I know its likely to be pretty "full on" but at literally 2k cheaper than commercial options, im willing to give it a read. As for your incentive, you could whip up a few sets of brackets on your CNC machine and sell them with the guide so people to copy your system I have the same coilovers as you and am literally fed up of smashing every speed bump in sight to the point where i barely use the car unless i 100% know theirs no speed bumps along the route! sure I can sort something out for you once I'm happy with the setup. Going to make a custom pcb for the electronic side when I get a chance and do away with all the relays I only mention this as I know you're partial to an arduino Quote Link to comment Share on other sites More sharing options...

andybp Posted August 19, 2018 Author Share Posted August 19, 2018 Well I've got the rear all up and running but it's taken most of the weekend as I had lots of problems with the electronic side of things turns out it was back emf from the valve block causing spurious problems which shouldn't have happened as they are all driven from mechanical relays which are immune from such issues unfortunately the electronics driving the relays seems somewhat sensitive anyway I've frigged it for now and will build my own, I have managed to get the front coilovers removed and fitted with air springs and back on today but I need to route the airlines before I can try them So that's my excuse for a lack of pictures, I've been too busy trying to get it to work will try and get some pics tomorrow. 1 Quote Link to comment Share on other sites More sharing options...
cs2000 Posted August 20, 2018 Share Posted August 20, 2018 (edited) Those Mechanical relays boards are normally pretty good, but general overkill for what i have needed in the past, They're usually fully opto isolated etc which sometimes is needed, other times not and can complicate matters. On my VDC/Traction control boards im just protecting from back EMF with a simple diode across the relay coils, seems to work well. Looking at your boards, your original solid state relays weren't opto isolated., the new ones (blue relays are) but i cant see any EMF diode on the board in the photo you've put up. Looking forward to seeing progress! Edited August 20, 2018 by cs2000 Quote Link to comment Share on other sites More sharing options...
andybp Posted August 20, 2018 Author Share Posted August 20, 2018 got the fronts connected up today had a few air leaks but still got a few issues I don't think I fitted the top o-ring properly so will have to strip them out again tomorrow as the fronts only hold air for about 2 hrs then the Z's on the floor the rear are good been up for 2 days This is the front installed 3 Quote Link to comment Share on other sites More sharing options...
Daisyduke Posted August 20, 2018 Share Posted August 20, 2018 (edited) That looks like it would raise the front so high. What does the min and max height look like? Awesome work Edited August 20, 2018 by Daisyduke Quote Link to comment Share on other sites More sharing options...

Awesome work not sure on max height but as it's set up now it pretty much sits on the floor at it's lowest in fact it is right now as the air has pretty much all leaked out hope to get that sorted tomorrow Edited August 21, 2018 by andybp Quote Link to comment Share on other sites More sharing options...

ChrisB Posted August 21, 2018 Share Posted August 21, 2018 Hey Andy, this is great Awesome re-purposing of fire extinguishers ..and of course use of Arduino. 1 Quote Link to comment Share on other sites More sharing options...
cs2000 Posted August 21, 2018 Share Posted August 21, 2018 Looks amazing! Hope you get the air leaks sorted, then we need some propper external photos and videos too. Is the pump loud?? I always imagine them sounding like a garage air compressor! Quote Link to comment Share on other sites More sharing options...

I always imagine them sounding like a garage air compressor! all seems to be holding air now. controller is temperamental ,same emf issues but I have designed a new one just need to make the pcb. The compressor is a bit noisy hopefully will be a bit quieter when everything's back together lots to do yet Quote Link to comment Share on other sites More sharing options...
andybp Posted August 22, 2018 Author Share Posted August 22, 2018 made the pcb and started building the new controller this evening hope to get this finished tomorrow evening 2 Quote Link to comment Share on other sites More sharing options...
Mik Du Posted August 22, 2018 Share Posted August 22, 2018 (edited) Well. This is all way beyond me but Wow... I just want to skip to the end! Hope this all works out! And can't wait to see the end product - had to comment something just to get on the updates! Edited August 22, 2018 by Mik Du 1 Quote Link to comment Share on other sites More sharing options...
andybp Posted August 23, 2018 Author Share Posted August 23, 2018 new controller / driver pcb is finished though I haven't tried it yet. should get a chance tomorrow after work. 4 Quote Link to comment Share on other sites More sharing options...
cs2000 Posted August 29, 2018 Share Posted August 29, 2018 Looks good mate. if you need any assistance on the PCB layout or arduino coding, give me a shout I know that PCB is a one off prototype, but im sure i could get that smaller if i built it in Eagle and had it printed over at JLCPCB, but for a rev 1.0 design, it does what it needs to do by the looks of it! 1 Quote Link to comment Share on other sites More sharing options...

As a pressure based system the arduino code is pretty much sorted I just need to write the code for the 2.4" touchscreen the only problem is that I haven't decided on the control philosophy and how the controls will work once I add the height sensors As for the PCB as you said it's a prototype and I've already started designing the rev 2 board in Eagle but it's always good to know there's someone I can run it by or the code for that matter. 1 Quote Link to comment Share on other sites More sharing options...

andybp Posted September 9, 2018 Author Share Posted September 9, 2018 It's a little bit one step forward 2 steps back at the moment I thought I was being clever with a bit more Ghetto Rigging, trying to use flexible hoses to go from the front struts to the body but hoses with the right fittings 1/8"Bsp and about 12" long are like hens teeth except for grease gun hoses. Damn I'm good at least I thought I was being clever watch the video and see so it seems grease gun hoses will hold 4500 psi of pressure as long as it's not air as it seeps through the inner core and blows apart the rubber outer scaring the crap out of me so back to the drawing board. 2 Quote Link to comment Share on other sites More sharing options...
