EGHM confirmed that the Bus Pirate will program ATMega8s at 3.3volts from AVR Studio. Thanks for the update.

Michal posted detailed instructions for programming AVRs with the Bus Pirate and AVRDUDE. But what happens if you have 2, 3, or even 7 AVRs on the same circuit board? Michal shows us how to use extra Bus Pirate pins to select among AVRs, or drive a 1-to-8 decoder to control even more chips.
Michal is also the author who added Bus Pirate support to AVRDUDE. Thanks for expanding the Bus Pirate universe!
Via Hack a Day comes word of a USB PIC-based STK500 AVR programmer. The really interesting part of this project, to us, is the stk500.c source that handles the programming interface. It should be potable to the Bus Pirate as a separate firmware, or as a mode in the existing firmware.
AVRDude already supports the Bus Pirate as a programmer, but STK500 emulation would make it instantly compatible with AVRStudio and a ton of existing applications.
Holiday cards that blink and beep have always fascinated us. This is our hackable DIY version, made with an ATtiny13A and a few LEDs. Push the button to play a short light show in the tree. We’re sending these to friends and family this year. It’s a handmade, hackable gift, and it was a ton of fun to build.
The card is also an homage to Velleman’s blinking Christmas tree ornament kit, and a kit-biz reference to the Adafruit Promise. (Did you know Velleman has a nixie tube clock kit? Really!)
You can buy a copy of our card at Seeed Studio. Assembled cards are $15, and a kit for adventurous solderers is $12. We’re excited to gauge interest an SMD kit, and hope to offer it as an option for future projects.
Video, hardware, firmware, and more, after the break.

UPDATE: Bus Pirate support is now included in the current AVRDude SVN version.
Michal Ludvig submitted a patch that gives AVRDude support for programming ATMEL AVRs and serial EEPROMs using the Bus Pirate. AVRDude parses ASCII terminal output at the moment, but we’re working on a raw SPI mode for better speed and performance. More in the forum.
The picture shows the Bus Pirate v3 with a Protostack ATMEL AT8 development board.
