Op-Amp question about linearity
Sylvain - Take a look at the LT1991/5/6 amps from Linear. They have matching precision resistors built-in, and you can change gain just by connecting different pins. Great...

DC offset on a DC signal?
I've found 3 documents to be invaluable when dealing with opamps ... TI SLOa030 Single Supply Opamps Especially good with a cookbook style. TI Sensor to ADC interfacing TI Single...

Protect AVR input from over/under voltage
It will depend on the size of the resistor. So long as the max current through is small enough, the internal protection diodes should be able to handle the overflow from the...

Problem with ATAVRDRAGON
Best to get it out of the way early in life. My own death-defying one was many moons ago, when I was but a titch. Needing a small powerful fan for my darkroom, I cannibalized an...

Where/how to purchase thousands of AVRs?
Try - free signup (or it was when I signed up ages ago) and you can set a target price for them to search/negotiate.

Fuel Injection works - Thank You
You are most welcome. The only payment we all really want is details on how things worked out. Pretty pictures are especially desired :)

Programming non-DIP Packages + Bootloader
One nice method I've used (if you have the board space) is to bring the ISP connection out to the very edge of the board, and have a slot cut into the board on each side. You set...

scanning LED clock
Fabio - Put up some pictures :) glitch - I don't think charlieplexing will work for a propeller clock - there's just not enough time. For example, you would want the propeller...

Need a 1-wire type protocol
Mike - thanks for the offer, I'll definitely take a look at whatever you have. It's not so much a bootloader that I would need as it is an application updater. I think that's...

Need a 1-wire type protocol
This thread has kind of morphed a little. Originally I was just looking for pointers on how to implement a 1-wire type protocol to transfer data from a main AVR to a Tiny....
