TOD controller - knob, wheel, or buttons?

[taylorRichie]

Thanks for the offer, and insight.

We're thinking 4 positions just as you said, and more than likely it'll be a 5 position dial. This is the where we haven't fully decided.

5-20-35-50-TOD

We have all the firmware and circuitry done, just waiting for another project to wrap before getting the boards shot.

sounds like you're using an MCU... are you going PIC or AVR... or something else altogether?

[taylorRichie]

Using a PIC microcontroller from Microchip.

And I can't really say "I'm" using anything... My brother is using it

[twistedsymphony]

cool I've done a few PIC projects in my day.

anything you can tell me about the design? which chip model and language are you using, internal or external clock? I'm curious how "picky" the VX is on the timing... I'm assuming not very since people got full lock by just applying 12V.

Are you adding any kind of power cleaning circuitry? automotive 12V systems is crazy harsh since the voltage and amperage spikes and drops all over the place whenever something kicks on or off.

Have you started working on a PCB layout yet, or are you still prototyping the circuit?

Obviously these are more questions for your brother...

excuse me if I'm excited... but it's not often I get to talk about my love of car modifications and circuit hacking at the same time

I understand if you want to keep the design to yourself for resale purposes.

Youn didn't think we were just going to forget about this...DID YOU???


Oh if only I had a dollar for every promised VX mod I've seen since 04...


Somebody had to stir the coals...

Somebody had to stir the coals...

Haha, I was thinking about this thread when I posted in the thread about the brake light. Was going to wait a day or two so I didn't look as desperate! Thanks for beating me to it

[twistedsymphony]

I lost interest in this when I decided that I'm going to do a 5-speed swap in the spring... in doing so I'll be losing the TOD system.. and gaining real 2WD and 4WD in the process

it will still be interesting to see how this turns out though.

[taylorRichie]

Hey I've been thinking about this thread for the past two months...

I hate the fact that it's "Done" but I'm not the capable party to finish it... so it's in my brother's hands.

And now with me going in to surgery this week... I don't know when I'll be able to help him wrap it up. Maybe a more realistic timeframe is a Moab 2009 Release But it's honestly an afternoons work (for him) then getting the circuit printed, housings ordered, and building up a few.



I'll try to put a fire under him now.

did I tell you I'm starting a Diesel engine swap and a 5 speed conversion

(just playin' of course, just another over promised under delivered claim)

[twistedsymphony]

hey the only reason I'm not doing the 5-speed swap right now is because My garage (not to mention my wallet) is currently tied up with this project



You know, I need at least ONE car on the road at a time.
5 speed swap is cheap money compared to this project.
