LOOKS GREAT!! fantastic job everyone. Mark I would think twice about having a vibrant color. Most people will probably want to hide the box, it is the function that is important....... best felix b. On Jul 22, 2012, at 5:56 PM, Mark Webb-Johnson wrote:
Guys,
Here are the latest pics. Very neat, and getting close.
This was supposed to be the final prototype, but some problems found:
1. Diag port can't tx while pic on. This is caused by the new voltage divider arrangement, and we're trying to add a diode to get it working.
2. 12v ADC measuring circuit doesn't work. Design issue, now ok.
3. GSM/GPRS switch stuck ON. Board design fault, now ok.
Other than that, it works perfectly. Can bus is fine, LEDs are the same brightness and easy to read. Transistor circuit for async comms pic->sitcom works great (thanks William). Cable arrangement is fantastic.
So, I've got a final prototype board coming in the next week or so. I'll run that in my car for 1 week, and if no issues are found will then give production go ahead.
Regards, Mark
