    Model engine CDI easy and cheap

    As above in #202 ...new order arrived and so showing the photos of top and bottom ....these are the "panelized" pcb's ....so 4 pcb's per panel, 5 panels in order. These are slightly larger than the originals from way back when to allow for the larger traces and solder pads.

    Model engine CDI easy and cheap

    OK...went back to my original drawings and changed the board setup so that only one pcb is made per panel. That will give you 5 pcb's in total and you may need to cut to size I imagine (maybe not, never done it that way) Generated the Gerber File for that as " Version 3 Add On CDI Single" which...

    Model engine CDI easy and cheap

    That would be 2 rows x 2 columns so "4" pcb's per panel, not 5....then there are 5 panels. So all up 20 pcb's....but at AUD$14 odd cheap as........ I "panalize" the panel so I can get more pcb's for around the same cost. It used to be that "panelize" was free but now a small extra charge...

    Compression ignition

    It's still a compression diesel engine with direct injection regardless. Physics just will not allow it to run on your standard pump diesel fuel, I thought that was obvious. Seems there is always at least one knocker, apart from the engine that is.

    Compression ignition

    George Punter built this Lester a few years back. Take note of the name as he is a retired secondary school manual arts teacher and winner of the Duke of Edinburgh trophy in the UK so no slouch when it comes to model engineering.

    Model engine CDI easy and cheap

    As the heading says ...easy and cheap...bugger all to play with and go wrong...anyone can access the parts from anywhere in the world. Can be put together by anyone with any wiring/soldering skills in a few minutes AND guaranteed to work first time, every time. AS it suits the hall effect...

    Model engine CDI easy and cheap

    Had a call from my mate the renowned Duke of Edinburgh Award winner George Punter yesterday and yet another of his creations now up and running on the modified off-the-shelf CDI system I designed. 1/4" spark plug and all. Said he did the Toyota jump when it first fired up but then he admitted...

    4 Cylinder Inline Engine

    Think you'll find those tygon tubes will flutter and close up to a degree on running.

    Model engine CDI easy and cheap

    Already posted a circuit and details on a cop type coil from a BA falcon...runs on 3v7 LiPo and NO driver required. Obviously you missed it.

    Model engine CDI easy and cheap

    The only reference to what you say as I can remember is, this is for the 4 pin DC CDI module which are all the same as far as I know. Obviously my circuit will not work with the HV (300-400v) 5 or 6 pin units. One link is here anyhow, just about to order a few more. In this instance from here...

    Model engine CDI easy and cheap

    Update for the original CDI Easy and Cheap. Recently found that some find the soldering on the small pads difficult and they sometimes damage the pcb traces. Seemed ok for me though but I just didn't want to have to add the leads for everyone so re-design easier. Decided to update the CD add-on...

    Arduino Rotary Table for Dummies

    Yes, I have the same query. #488 says go to some web site, that website tell you to come back here....seems typical of some of these writeups.

    Fuel for compression ignition engines (around 1 cc) - diesel model air plane engines

    There are other alternatives out there for fuel as, if like down under here in Aus, ether is almost unobtainable. Mention ether and they are likely to call ASIO these days. I have details on the alternatives somewhere, just have to find them. I do have a dark brown glass 0.5 litre bottle of the...

    Advice from me would be, as this is your first engine, start with something simple like the Simple Simon single cylinder engine I included here some time back. It might feel to you like it is "below you" but believe me, you will have enough to do there to keep you going for a while. Plus you...
