When winter times come in my van its always a horrible time of year as the 2.5tdi T5 is a slow warming engine and the windscreen is so big it hard to scrape the ice, after getting a crack in my current windscreen I started looking at if it possible to retrofit the heated screen out the new T6 into my T5.
After phoning the windscreen company and asking if this was possible and they said the scenes are the same shape/size this was the major part out the way I now started looking at what else was needed.
There are some changes that would be needed and that was there no longer an aerial in the windscreen (no problem as I had fitted a shark fin aerial for FM,DAB and GPS at the rear.
Also the mirror is completely different as all heated windscreens come with rain and light sensor in the screen.
The windscreen would also need wiring but decided this could be done afterwards.
With it all looking good the windscreen was supplied and fitted by Corby Windscreens.
Next was to source a mirror and and after a little hunting found a 2nd hand Skoda Kodiaq one for £14 (Part number – 3G0 857 511AF) with this ordered and new trims from VW this was fitted and clipped into place (this makes the inside look much more modern.
This is the longest and hardest part of the job, (Wiring diagram to follow later)
For me it has to look as factory as possible so I matched as many connectors and pins as possible, I also mounting the relays in to the relay carrier under the battery. My van didn’t have heated rear windows so I decided to use the original heated rear wind switch and connect this the Central Electric J519 as per VW heated rear windscreen is wired (reason for this was it gave diagnostics to the heated windscreen, it also let’s you change the length of activation with VCDS) after plugging in my van to VCDS and checking it listed heated rear window as a option but also in the list was heated front windscreen! Even better.
After find a pin out data for the J519 and finding mine has the pins where heated windscreen should fit, a quick wire up and testing found it picks up the switch press but that is all and doesn’t turn anything on! On the pin data it lists heated windscreen as “not delivered yet” back to connecting the heated rear window route again.
First thing was to make the relay looms and holders, I used the VW relay holders that clip into the factory relay carrier under the battery – The windscreen is 2 separate system, the driver and passenger side runs it own circuit this is why 2 relays are needed and also to handle the current
Next part was to take a fused feed from the battery distribution point next to the relay carrier
Once out the power wires were run up towards the windscreen and signal wire was run into the van and towards the J519 – Central Electric unit
No onto the switch and inside of the van, as mine is a van I didnt have a heated rear window so used a rear window switch, this is wired into the J519 – Central electrics and J519 then provides the feed to the relays, this setup was used as with the diagnostic tool I can adjust the time the J519 keeps the screen on for before automatically switching off.
Once this is completed and all wired in next step is some coding and changed in the J519- Central electric ECU. I needed to add +1 to my original coding to turn on the heated rear window function (for my front window) Once done exit out and lock the vehicle for at least 5 minutes. Now unlock and connect scan tool again and check coding has changed. If yes you can now go into adaptions and change the length of time the window stays on for.
Check everything works and then put everything back together, wait for the frosty morning and enjoy your hard work.
We had some new windows fitted in the bay window of our house to replace the old wooden ones, the new ones are nice bright white triple glazed windows and very nice and make the room very quiet, but as the old curtain track was screwed to the wooden window frame we needed a new curtian pole.
Now quick look online showed universal poles for about £60 but these looked quite poor and required different brackets buying. Now I also found a site that would make pole with bending and brackets to suit but quick pricing showed this was going to be £300-400! This seemed expensive to me and I could make something better and cheaper.
As I already own a JD2 tube bender and 1″ former this sounded like a good base to make a pole, I found a website called metals4u and these listed 5 meter length off 1″ aluminium tube for around £12. But would it bend??? Checking some specs found that 6063 is a good workable spec and the tube from metals4u is 6063, so some quick measurements were taken.
Now because our bay window has return in the walls the hole in the wall is narrow compared to the bay window, so I designed the pole to mount the return on the walls and the centre mount is a ceiling bracket. I ran a 80mm offset from the window frame. A quick design in some CAD software called onshape looked good so I ordered 2x lengths of 25.4×1.6mm by 5000mm(1 spare incase it went wrong), 1x 22.2×1.6mm by 500mm and some 2mm flat plate.
Once the order has arrived I started by carrying out a test 90deg bend, cleaning the tube and former and using a lot of lube on the former it seemed to bend very nicely (I also marked the tube so I could work out the loss round the bend) with the measurements I proceeded to bend the other side and made the curtian pole I left the ends too long because it could cut these down later.
For the wall mounts I cut a 75mm hole in the 2mm plate and also a 22.4mm hole for form a donut or polo mint shape, then using a 75mm length of the 22.2mm tube I welded this onto the plate with the idea that the plate would screw to the wall and the rail would push into the smaller stubs, the problem I found is that was there not enough clearance and also the wall were not straight! While looking for curtains I found the perfect wall mounts and at £8 for 4 it was a no brainer to use these.
Now onto the centre mount the orignal idea was to cut some 2mm aluminium sheet and drill a 25.4 hole and then run that upto the ceiling with a 90deg bend and weld this to the tube see below
But, after some thinking I decided that the mount would need reinforcing around the screw holes and wouldn’t leave me any space to slot on the old mounts I changed to a steel centres mount. I brought some 12mmx3mm steel plate I clamped this into the vice with a ofcut of the 25.4 tube and proceeded to bend the plate round the tube to form a hook I then measured how far the curtains sat above the pole and added 10mm, with a 90deg bend added and 3x mounting holes I then painted it silver.
With everything ready it was now time for fitting, this was quite straight forward as everything was made to fit the windows. First I fitted the centre mount as the no up/down adjustment for this, with the pole now fitted into the centre mount I moved onto the wall mounts with it all mounted I removed the pole and put the curtains on and refitted the pole, job done now time for a beer
It was a short lived beer as I done a good job the wife turns up with some curtains for the downstairs bay! As I managed to bend the tube with only using the first tube I still had a spare 5 meter length of tube, so we started again and bent this to match the lower bay, this one is slightly different in that the middle mount needs to be wall mount and because they £96 curtains were in the sale for £11 they didn’t have the larger drop left so I needed to mount the pole inline with the top edge of the window, a hi-tech drawing this time.
This time as the load was being supported by the length I decided to triangulate the bracket but this all need to go up the wall. With the left over 12mm plate I made a new wall bracket that supported the pole and also the triangulation held the pole in place.
In March we brought a Rollplay VW Splitsceen camper kids ride on car this was the single wheel drive 6Volt model – It was being sold by Argos for a very good price as the 12v version was 4x the price!
After a summer of use the car has been really good apart from being 1 wheel drive on our bumpy garden the car get stuck and we have to go and push him, So i started looking at converting it to 2 wheel drive – You can go 12 volt conversion at this point but the extra cost was not worth it for me as I had a good battery and all the lights were setup for 6 volts
Now start by disconnecting the battery and unplugging the old motor,
Now turn the car over and remove the wheels caps and pins holding the wheels on,
Remove the rear wheels and axle
Remove the screws holding the old motor and remove the old motor
You should now be left with a empty rear end.
Test fit the new motors (note on mine the new motors fitted towards the rear)
I also had to remove a mounting hole off one side of the housing
With them test fitted now remove and solder some wires to each of the motor terminals (remember to swap colours for each side so the motors run opposite directions) Heat shrink the wires and leave the excess to reach the connector.
Refit the motors and run the wires through, refit the axle and wheels. Turn the car back over and we will start on the wiring using a multimeter connected to the old motor plug check put the car is forward and check which way gives you 6 or 12volts (if you have -6 or 12volts the power is on the black lead) make a note what colour wire on the car side gives you positive power. Now connect each motor in turn and check they spin the correct direction (if you reversed the wire colours on the motor you should have the same colour wire for forward each side)
On mine I remove the old plastic plug from the terminal on the old motor, these terminals use the 6.3mm male spade terminals but struggled to find anyone that made the plastic housing so we reuse the housing with new space terminals. I connected both motors and ran a 3rd wire out for the headlamp output. With the spade terminals fitted i pushed these into the old plastic housing.
Next because we knew which wire was positive I could fit the diode for the headlamps, this stops the headlamps working in reverse, diode stop current flowing in the striped end, so it goes positive power into non striped end and the striped end towards headlamp. With this all wired in tape the loom and secure all wiring and plug everything back in.
Now for the testdrive: After popping my 2 year old son in and sending him off all was going well until we got to the grass and the car stopped, (He shouts battery is flat daddy!) I walk over and try the throttle and it works fine, another 5 meters and it stops again. I think it my son stopped pressing the throttle but the next time it stops right by me and a second later I hear a click.
Back in the garage and checking I find a thermal fuse in the main battery lead, now with the 2 motors and grass it trips the thermal fuse, so next mod was to cut the thermal fuse out and replace with a standard inline fuse with 7.5 amp fuse, with this done next night we had a good drive all round the garden with no getting stuck and on pavement it faster but my 2 year old can cope with the extra speed no problem.
Due to some electrical work the weather station will be offline today (Thursday 1st August 2019)
Finger crossed will be back online by Friday 2nd August
As the old weather station was playing up (loosing communication with all sensors). I have saved up and bought and new weather station – Davis Vantage Vue
This new weather station has a greater range 300Meters vs 100Meters of the oregon scientific WMR200 – also seem much better built, downside are no optional extra sensors can be added to the Davis and the Davis is more expensive (When you factor in a data logger too)
The main display will live in the living room and using the IP data logger means I don’t have to put it next to the computer, This will give me more accurate inside temperature measurements and means I can keep an eye on the readings when in the living room
The Integrated Sensor Suite (ISS) make installation very simple, with only 1 unit to cover wind speed and direction, Rainfall, Outside temperature and humidity. using a TV aerial bracket and 1.5″ pole (3.6 Meters long) the sensor suit is mounted the gable end off the wall and sticks above the roof line to give as accurate wind measurements as possible.
Check the live weather out here:
I’m currently setting up my weather station in Irchester, The station (Oregon scientific WMR 200) is installed in a temporary position on the fence post for testing, The station display is connected by USB to a Windows 7 PC running as Virtual Machine on VMware ESXi 6.7 on a Dell R710 Server
This runs Weather Display software from Brian Hamilton with a 1 of fee for life. The software has evolved over time and I don’t think it the most user friendly but has many good features. This logs all the readings from the station and logs and graphs the weather. This then creatates a small .txt file that is uploaded to the website off your choice.
My Phoenix Trike (which my dad Dominic built many years and sold on, I then brought back about 8 years ago)
After putting back to standard and using it for a couple of years it was time for a change. I decided to headstock off and reweld back on with a greater rake, I also cut the rear suspension out narrowed the swing axles 3″ each side and made custom trailing arms with coil over suspension units
In this post I’m going to explain about the fuel injection conversion. It was decided that I was going to set myself a budget of £500 for the complete conversion. I will split this blog post into sections:
When I started the conversion 4 years ago there was only 1 option for a cheap ECU this was a megasquirt unit and at the time there was megasquirt 1 and 2. I went for megasquirt 2 with version 3 PCB, the reason these ECU offer good value is that you have to build the main board yourself (main processor is ready assembled). I ordered the complete kit with the Jimstim tester.
Once the kit had arrived I double checked the contents and laid it out on the workspace (dining table)
I brought a better soldering iron and also practised soldering once I was happy with my standard I went onto making the Jimstim board this went quite well but made some poor soldered joints, once they had been corrected I went into making the megasquirt, this all went well but you do have to make so choices while building on what options your going to run, I wanted to do away with the distributor so wasted spark and coil pack was needed so I decided on the Ford EDIS system. (If I was building now I would have used the VW wasted spark logic coil)
With the EDIS system the ECU was simplified which meant very little modifications needed. Once the ECU was built I then inspected all solder joints and setup the Jimstim to test the ECU, all tests completed it as then time to clean the board I removed the main processor and using electrical cleaner removed any flux left from the soldering once dry the ECU was assembled into it case and processor installed for the final time.
Here a time lapse of the build:
On the VW beetle engine I like the look off the twin carburetor setup but this is also linked with distributor, fuel pump and linkage system all showing at the back (in the beetle this doesn’t matter as it covered but on the Trike it all exposed) so it needed to be simple and twin carb looking but injection and cheap.
After some looking I found a set of Honda CBR400RR throttle bodies with injectors for £10.50 of EBay. These are used on a inline 4 cylinder engine but looked like they could be split, after receiving them they do just unbolt in half and provide 2x 2 cylinder throttle bodies, there are some issues the idle speed adjustment screw was only on 1 half with a link rod connecting all 4 together and the fuel rail linked all 4 together.
Fuel rail was simple cut in half and add the 4th missing mount to hold in place as it made off steel I welded on some an-6 fittings to each end and did away with there fuel pressure regulator.
I cut the fast idle/ idle speed rod in half and removed the coolant fast idle system (my engine is air cooled)
For the idle adjustment screw and rod supports I was bit stuck as I had 1 side but was missing the other after looking at making a new bracket and bush (I found another set of throttle bodies in eBay for under £15 so I brought these and borrowed the parts for the missing side)
The throttle bodies mount to round stubs using rubber seals. I got my local engineering shop to make me some stubs and tapered tube to go from the throttle bodies to the VW intake size hole in Aluminium, as the original intake stubs are Aluminium I cut the old ones to leave me the bolt flange and welded the tubes onto them (excuse my Aluminium welding is not the best)
This gave me a nice neat looking all in 1 throttle and injector unit with a Throttle Position Sensor (TPS) built in.
Because the Trike had a carburetor before the fuel system needed quite a few changes.
First change was the going to be cosmetic (aero filler cap). Because there was not enough clearance between the body and tank I notched the top of the fuel tank to give me enough room to flush mount the filler cap.
While the fuel tank is out I changed the small feed and reverse outlets to an-8 these will now be feed and return for the fuel injection system. The lower fitting go straight into a high pressure fuel pump this then feeds a fuel filter then into the first throttle body round to the next throttle body then on to a fuel pressure regulator and should be straight back to the tank but as the old fitting was a reserve port it only just above the fuel out and I was worried about high pressure return fuel disturbing the fuel out.
I decided to make a little swirl pot to slow the return fuel down and stop it disturbing the fuel out. This also takes the an-6 hose and converts to an-8 for the tank.
For the ignition system I wanted to run wasted spark and do away with the distributor to keep the engine looking very clean. When the project started the most simple way was to use the Ford Electronic Distributor Ignition System (EDIS) this setup only requires a crank sensor input (No cam sensor is needed). The Variable Reluctor (VR) crank sensor provides a signal from a 36-1 crank wheel mounted on the crankshaft, this signal is sent to the EDIS module that’s turns it into an RPM signal for the ECU, the ECU then provides a saw signal back to the EDIS to alter the ignition timing to the wasted spark coil pack.
The first job was to mount the 36-1 pickup wheel as the engine never came with one. Most conversions bolt this to the back off the crank pulley but as the Trike engine is on show I didn’t want this sticking out so I decided to mount it between the engine and pulley, this in turn made fitting quite difficult, we machined the back off the pulley to give us a flat surface then a spacer was made then using some aluminium, small neat grub screw secured it all together. Then the block of aluminium was machined to act as fuel pump blank and VR sensor mount.
A Mount was made on the main Chassis for the EDIS control unit. I then made a mount on the back off the fan housing for the wasted spark coil pack a set of Ford plug leads connect to the Beetle spark plugs.
A blanking bung was made for the hole where the distributor used to fit.
Throttle Position Sensor (TPS) this was easy as it came fitted on the throttle bodies (or so I thought). Until I tried to get the connector for the for the TPS, it took about 5 wrong connectors until I found what looked like the correct one, the only problem was the only place that sold them was in America and the connector was very cheap ($3) but with $15 shipping I didn’t want to order without checking, the company that makes the connector (sumitomo) have 3d drawing the only software on my computer that would open it was my 3d printer so I decided just to print it out. With a 3d printed connector it fitted the TPS so I ordered my connectors.
Coolant Temperature Sensor – As the trike is aircooled there no coolant but still need to give the ECU a temperature reading there debates on to what to measure (Oil or Cylinder head), looking at some newer fuel injection beetle engines they run a sensor in the head that pokes into the oil system by the rocker cover as my engine was a brand new Mexican engine it had the boss for this sensor built in, so after drilling the boss out and tapping the correct size thread I screwed the new sensor in.
Drilled and tapped cylinder head boss
this sensor is going to be a VW open end IAT sensor this will be mounted below the air filter and above the throttle body.
Do to a change of plan with airfilters (the weber twin 40 air filter I was going to use hit the body) I changed to 4x little airfilters each filtering air for it own cylinder the IAY sensor was mounted in the top of one’s of these airfilters.
This is located in the ECU and the throttle bodies had vacuum ports on each one. So pipes run from each throttle body to a 5 way adapter and then onto the ECU.
I made the wiring loom from scratch. Made a list of which wires go where and what need to pass from the engine loom onto the main loom (Oil light, battery light, Ignitions feeds etc)
Next step was to source all the correct terminals and connectors, most were simple Junior Power Timer (AMP) some were Ford only (EDIS and Coilpack) the troublesome one was the TPS as listed above. For joiners in the loom I used these water proof connectors (Click here 2 Way, 3 Way, 4 Way , 6Way) For relays and holder click here. With all the connectors I tried my normal crimping pliers but wasn’t happy with theverything result so looked online only to find some very expensive (£800+) commercial tools. With these being way too expensive I found some pliers online that looked good and priced in my range so took a gamble, I ordered the PA-20 when these arrived I was so impressed I ordered the PA-09 for smaller applications (I’ve been told these work just as well on the automotive terminals)
More updates to follow
Really sorry for the lack of updates there have been lately.
Just a quick post keep you informed of what I’ve been up with, and let you know I’m still alive
We have made a water hoverboard that works on water.
Phoenix trike is coming on it unit fuel injection conversion
I have built 3 quadcopters
My VW Corrado G60 has sold but I still have my T5 van
Over the next couple of months I hope to get this all documented for you and put up on my blog for you.
I managed to find a second hand CNC3020 milling machine on ebay for a nice price so snapped it up. Collecting the machine the person showed it moving around but said he never got on/got it working properly and has given up with it, sound like a challange and I like them 😉
Once I had got it back home and set it all up, installed the software and gave it a try – a quick air cut with the skull and cross-bone test pattern (having the cutter high up and not cutting anything). All looked good so on with a test cut, after setting the cutter hight and setting the machine going and the first cuts were made:
Not too bad apart from the cutter has left marks where the head should have lifted up and the size off the cut is a lot smaller than the diagram shows.
Looking back at the machine moving the spindle 50mm on the mach3 software but it only moving around 30mm on the machine. A quick check with the settings and everything is setup as the instructions say. After some trial and error I found the correct setting (sure it was 320 or 360, where the manual gave 450!) with this sorted out I then set about tuning the motors they seem to have a sweet spot where they sound correct.
I then checked the machine over and found missing and loose screws with these problems corrected I then found the Z axis had 2.83mm off play/backlash I stripped the machine apart and couldn’t find anything wrong? So I got a local machine shop to make me a 2.83mm spacer with this fitted all the backlash had gone and now it should cut correctly 🙂
Next task was to learn G-Code, there lots off guide but it quite a simple line by line text based system with some G-Code handwritten and learnt now to move onto CAD/CAM programs. I tried quite a few but the best one I have found is CamBam this is a 2.5D program where you draw in 2d and add machining depths in to give the .5d. You get 40 free trails so give it go.
Now to make something useful, I did a basic design for a door sign and set the machine off cutting it out
The finished sign:
I now used 2 cheap solar LED lights I mounted the LED’s into a drilling so the LED was a tight fit into the sign
With the lights switched off the sign looks like this
As the sign looked good I now un-solded the LED out of the solar light and made some extension wires so the panel can be placed away from the sign.
