This week I sold the last AVR HV Rescue Shield kit in stock! This is a significant milestone as it means I have finally sold off all of the kits from the original PCB fab run. At the time I wasn’t sure if anyone would actually buy such a thing, so pulling the trigger on what seemed like a huge number of boards was a leap of faith!
I want to thank everyone who bought kits and PCBs. Thank you for supporting me and the site!
Rather than reorder new boards of the existing design, I am taking this opportunity to re-evaluate my approach to a couple things, with the goal of reducing the BOM cost and lowering the overall cost of the kit.
The bad news is that this means there won’t be any more kits in stock in the short term. I’m planning to release a new PCB design within the next couple weeks, which means kits would be in stock within about a month. Because this is a busy time for me, I can’t promise specific dates, but I will do my best to keep the process moving because I know there are people waiting for the new kits.
If you want to try your hand at surface mount soldering, this is a fun project that can be completed in a couple hours with a decent soldering iron and a pair of tweezers. The instructions aren’t perfect (I had to short across the PCB pads for D1 and D2 to get my programmer to talk to the AVR, and at the moment you have to install Eclipse to compile the hex file) but I am confident that these minor issues will be fixed shortly!
I just uploaded version 1.1 of the Arduino sketch, which fixes an issue with garbage being printed in the serial monitor between burn cycles. I also made some minor changes to try to reduce the likelihood of getting serial gibberish upon opening the monitor window, although I’m not 100% sure what is causing this. The sketch was compiled and tested with Arduino 0017.
I have verified that the shield works with the Atmel ATmega328P AVR microcontroller.
