Level translation 3.xV <=> 5V
Good point AndersAnd! Hmm, It could work, but maybe in bandwidth's expense? P.S. It's not an issue for me anymore, since my devices are already out there with TXB0104 installed...

SinaProg - GUI for AVRDUDE with AVR Fuse Calculator
Actually, USBtiny programmer works with either "x" or "usb". It worked even without the code addition! I suppose you know better. :) I asked you about the fuses because...

SinaProg - GUI for AVRDUDE with AVR Fuse Calculator
Nice work! The fuse calculator is a great add-on. Did you wrote all the possible fuse combinations by hand? There are a couple more things you could do to make it perfect (from my...

Idea: Stack as randomizer/random generator?
I use TCNT registers from various timers that I have running different PWM frequencies and CTC modes, combined with EOR. It works great for me.

Pony Prog USB
Ponyprog actually WORKS with USB to SERIAL adapters (specifically mine, with FTDI IC inside and a full RS232 IC). The only problem is the speed. It's toooooooo slow. I still use...

Bray'sd terminal--misses incoming characters.
Using PortMon, I've found that Bray's terminal is using something like polling to fetch the data, not events, so it is prone to loosing data when streaming high baud data. For...

isolated amplifier for 8Ohm speaker.
Isolation of an analog audio signal is easily done with transformers. There are 600/600 Ohm transformers for small signal audio.

TXB0104 interface level translator
What's your 3.3V regulator? Is it ringing too? Can you post the schematic around the TXB0104? I've checked my board and the 5V line also have a ringing pulse of 100mVpp at 62.5KHz...

TXB0104 interface level translator
Is this happening on a single prototype board or the whole batch? Mis-soldered traces could cause that. 200mV seem a lot to me. Maybe your 5V regulator is not good. We used to...
