controlling of a handpieces of dentistry
you also need the special connector for it. Usually, you need air for cooling, and air or electricity for rotation depends on model. If it's air forget it. regards.

differential ADC at potentials outside GND..Vcc
do you know zetex and specially there zxct1009 current sense device. They are available in sot23 package for about usd 1.0. They only need a resistor to convert current to voltage...

Troubleshoot my Silly Mosfet Circuit IRF9Z30
if you find out a lm311 (a voltage comparator with open collector output)in your junk box, you will save the 3 diodes,the 2n2222 tansistor and the base resistor. the supply...

ATMega88 stopped working
there are a lot of tread here concerning this common problem. please use the search option. I think you just need a square signal to feed your avr clock with to make it run again.

Galvanic isolated ISP
Have a look on this appnote from atmel, it give you an idea for the opto choise. like said glitch, you do not need bi-directional line here. http://www.atmel.com/dyn/resources/...

Ballistic Chronograph - first project and first PCB feedback
A hint concerning the pcb becarfull with 5V track under the voltage regulator. Because the metal of the 7805 part is the ground.

Circuit not functioning without avr isp mkII plugged in.
i allways use a 10K resistor ( this is not a ood reason, i know). and from atmel datasheet i have found this TA = -40°C to +85°C, VCC = 2.7V to 5.5V (unless otherwise noted)...

Circuit not functioning without avr isp mkII plugged in.
use a 10k resistor instead of the 4K7 in your reset line. connect your analog power supply (avcc and agnd). Add a capacitor as close you can your µc vcc pin.
