	In this post on the BOINC dev forum it says you "publish diagram how to build your own detector". I can't find the diagram anywhere. Have you not published it yet or am I missing something?

	It is simple device (I hope). On next one model we want use Attiny4313 instead of 2313 - you can use it as well. In 2313 is not enough memory to use both HID and display (in current application we don't use LCD). ____________ Regards, Krzysztof 'krzyszp' Piszczek Android Radioactive@Home Map Android Radioactive@Home Map - donated My Workplace

	Thanks, looks pretty simple, especially if we ignore the display and buzzer. But is the SMPS transformer easily available (there's no part number)?. A PCB layout would be nice :) I'd do it myself, but haven't desined a PCB for years now :( Come to that, I don't think I even have my etching equipment any more :( Once the source code is available, how do we build the software, and more importantly how to we flash the chip? Interesting project! Al.

	I have used AVRMkII programmer to program it. Pictures of my detector will be available on web site tommorow... ____________ Regards, Krzysztof 'krzyszp' Piszczek Android Radioactive@Home Map Android Radioactive@Home Map - donated My Workplace

	Nope, not a project for me. I don't have my PCB etching shop anymore and it's just too complicated to rat nest wire it on perf board. The ATtiny 2313 and 4313 come in PDIP package which makes it easy enough to solder but the component count makes it too easy to goof up when doing it on perf board. The compiler/assembler needed to produce the flashable file is free as well as the software for flashing. It's all part of the AVR Studio package available for free from Atmel (ww2.atmel.com). The programmer would not be free though there may be schematics around for building your own. Hardly worth the cost/bother unless one intends on doing more work with Atmel's AVR family. Thanks for the diagram but I'll just wait and buy one when they become available from the project. BTW, I like the LCD display. Is that for on board diagnostics?

	BTW, I like the LCD display. Is that for on board diagnostics? No, on LCD we would like to display current values of metered radiation - this is reason why we change CPU (2313 have not enough memory to supply what we need to do this). ____________ Regards, Krzysztof 'krzyszp' Piszczek Android Radioactive@Home Map Android Radioactive@Home Map - donated My Workplace

Unfortunately the transformer is custom built, so it's not available as part. I can find and post the specs if you're interested. The core should be easy to find, it's also relatively easy to wind the trasformer.

	To build a transformer you need: - 2x ferrite EF16-R-0.0-3C90 - 1x EF-16-K-H-12P-12,5 - copper wire DNE0.35 and DNE0.10 Primary winding is 12 turns of DNE0.35. Secondary is 300 turns of DNE0.10. Every layer of secondary winding needs isolation from previous layer. As insulation you may use ordinary scotch tape but stripe of paper + a little of tape is even simpler to use.
