ATtiny85 + 100 ohm resistor = RFID tag?
Yes it's a 1mH (1000µH) ±10% inductor (or coil as he calls it). Please note the third ring is red and not brown as you can see if you look at the hires picture. So even if it...

Sorry but I will say it's stupid to make a buck converter to get the voltage down from 12V to 6V, when you can instead just use a buck-converter conneted directly to the 12V...

Wire length on ISP with JTAGICE mkII
Slow down the programming speed, that might help. Are you AVR decoupled properly? Do you use external or internal oscillator? Have you anything else connected to the ISP lines?

what kind of socket for AVR ATMEGA168_10MU 32-pad QFN/MLF
PLCC sockets are for PLCC devices, they wont fit QFN/MLF. PLCC has leads, QFN/MLF has no leads. You don't use sockets for QFN/MLF devices. They are soldered directly onoto the...

Memory Recommendations?
You could also have used an SPI 25xxx EEPROM instead of an 24xxx EEPROM. But so far the ony 64kB SPI EEPROM seems to be Atmel AT25512: But it...

I would throw those 4 amc7135 drivers away and use a single step-down (Buck) SMPS LED driver that can operate directly from the input voltage. This will also be much more power...
