Looks like FET's (field effect transistors) will be used. So no additional clunky automotive style relays to be wired with moving parts and clicky noises. The amp load from the solenoids is pretty low about 750mA, so probably MOSFET style, doing this will keep size down too since they can be integrated into the control unit.

 

Very nice, can't wait to see the final results!

 

Me too.

 

YO! Haven't heard from you in awhile. Hope you and your son are doing okay in the slow season. Steady progression I guess, everything is on track. Surprised you looked at this thread having a stick.

 

Not even using a arduino anymore, has been simply reduced to a ATmega328p.

 

Interesting, can't wait to see where that leads.

 

what are you using to program it with?

sweetness, by the way

 

Arduino

 

i meant hardware... just using the 'duino board, or an fdti cable, or...

 

Yeah, a Arduino board and FTDI cable will be used to program the chip, then removed and put in a socket on my shift controller board.

 

Looks like the revision will use mosfet.

 

have you tried it with the mosfets yet? i'm wondering how hot they'll get. and are they "on" when digital out is "high" or "low"?

thanks in advance, i'm starting to get back into arduino, so that's what's with all the questions

 

Wait, where is the flux capacitor? How come it didn't make it into the final build schematic?

 

No idea, hasn't been built and tested yet. I will update when more is done, might have to give me a couple weeks.

 

It was phased out when the 88mph goal couldn't be reached and walmart quit selling plutonium.

 

duh!

 

So if I had the time and ambition to build more of these and sell them, wonder if it would be worth my time...

 

Depending on final price I would be interested.

 

As far as price it would be pretty cheap, but such a niche market.

 

Yeah, you would not sell a lot of them but list them on ebay and you would get a sale every now and then.
