That looks like far too many holes to drill (UYM,J)
I did consider counting them on the way up yo Stoke, going to see Top Gear Live in Liverpool tomorrow, but I decided against it. Been dragged out for drinks with my drunk sister and friends. And they've all desserted me for the toilet.
Started soldering the main board.
So far I think I've done a reasonable job, but it's only the easy bits. Felt like I was cheating using the long pins of the transistors to make things easier!
So far I've learnt that dip sockets are quite easy to solder, female pin headers are an absolute pain.
I've finished the board. But it's not working properly :C
The second and third shift registers aren't working. They seem to cause the LEDs to be full brightness . I've checked the wiring but I think I need to check again with a fresh mind. Though I did read something about communication issues across shift registers with poor wiring.
Not had chance (been bothered) to have a proper sit down with it. Bought a cellulose decorating sponge the other day, so I finally have sponge!
Removing all of that multi-coloured capellini laying all over the board should help a lot.
It needs to taste good though!
Arduino... The taste you have been looking for.
It seems the step up reg might not be the best way after all. Either that or the Pro Mini is consuming more power than I realise. Got about a week from the last set of batteries.
New plan is to drop the clock speed so it can run at 1.8V and switch the step up regulator on when the temperature is read. The sensor needs 3V.
I've also ordered a couple of Atmega328p chips to make a barebones board.
And my Nanos have /finally/ arrived. Got one of them controlling my bedroom LEDs now. Borrowed the mini that I'd set up to do it before.
