I'm building a robot with many different voltages here.
I have managed to avoid voltage regulation by cheating, I run the motors that are rated for 4.5 volts at 6 volts from a RC NiCd battery, and I use an RC Electronic Speed Controller that can give 5 volts to the RC receiver, the wireless camera and the Picaxe. I feared that this might be a problem and turned to the all knowing LMR forums for help. And help I got...
Fritsl answered:
" I have never fried any picaxe, and I sure have done all the wrong things with them; Hooked motors up, that generated power back etc.
The SRF05's on the other hand; Each time I am just a little sloppy, I fry one! The fried ones can be used as models for drilling and fitting later, but still.. What I am trying to say is that they are sensitive!"
Well, to make a long story (involving 4 days!! of trouble shooting), I now have a fried SRF05 that I can use as model for drilling and fitting as well.
It seems very unlikely that I'll manage to get a new one shipped before the challenge ends tomorrow morning, so improvisation seems to be the order of the day (or this night to be more specific)...
Bollarks.
