Absolutely - read the thread
... there are several!
see the very first post for an index, and the second post for a list of components
(... and my comments below for the components I first used - and still use! )
Rebo wrote:Can the relays be built up on bread board? I do have a cnc that I can use for the pcb but I would need a mach file.
yes indeed - read the thread
This was first suggested by Frakk on page 2...
have done it myself since to test other components. it's very easy
there are a number of well documented examples contributed by other people that have tried breadboarding this circuit in this thread - I recommend you search them out, as you may be able to avoid any problems that have been worked through before

Could someone post a 'complete' list for me.
you dont need to know much about electronics - just read the thread dude! -
That's why I wrote it - it's instructions from start to finish...
Effectively, the list you asked for is on the first page in the second post - the circuit is so simple that I deliberately didn't force components on anyone in case they couldnt find them and might think it wouldnt work with any other type from those listed... the components are so unbelievably simple, that you can pretty much make it up as you go along - other than the relays, all my bits came from maplins "lucky bags!" - this has to be the simplest DIY electronic solution by a mile... and the cheapest! I can't find an easier way of achieving variable speed multi directional motor control (and believe me... I have tried!!)
Here, just for you is the list of bits (with Maplin codes) that I used - the original circuits STILL WORK despite many hours of testing under load
Apologies to anyone in a country that does not have Maplin
each wiper needs:
DPDT relay £4.99 each - N08AW
Relay Socket £1.69 each - N32AW
1K resistors £0.14 each - Dude - a 1K resistor is a 1K resistor
2 diodes (from a lucky bag... about £0.10 each) - ANY that can take at least 12v and 15A - never had a code.
1 NPN Transistors (from a lucky bag... about £0.15 each) - I used BUX127, but have 6 different types now, all of which work well
thats it! - the component specifics just dont matter. As long as minimum voltage and current requirements are met and/or exceeded, it will work fine. If in doubt, just ask an assistant to help you choose a diode and/or transistor - they are usually pretty clued in
page 14 post 9 (how it works) will help to understand what each of the bits does and how it all hangs together...
should definitely help with understanding where each component goes in the circuit, and make troubleshooting easier
