Hello, i have a few questions about the schematics.
1. What is the value of C1, measured in uf? i don't understand the 'm'
(is it supposed to be mf, i understand that) also does C1 have to be polarized (i assume thats why the symbol is different on the schematic).
On the power supply schematic i have afew more questions.
2. What is the value of C7(doesn't have a unit)?
3. Am I correct in saying that the value of R9 0.22 ohms(it just seems like a strange value, but then im not very experienced
)?
4. Could you reccomend parts from Digikey ( www.http://www.digikey.com/ ) to fill the spaces of T1, L1, D1. This is the only place i can order parts from, as there is not alot available in my country (Australia).
5. Do you have board layouts for the emulator and power supply?
Now the firmware question
6. What version of yammp's firmware did you modify and will your modified version work with the prebuilt yammp-3/usb ( http://www.jelu.se/shop/product_info.php?cPath=1_21_24_25&products_id=28 )
Sorry for all the questions but i am eager to start building this

3. Yes. R9 - 0.22 Ohms.
4. You need to made T1 yourself.
5. No.
6. I don't remember... Firmware work with yampp3/usb but in FAT32 mode without usb.
) сразу начинает скакать то 0 то 1. при чем, даже если подкючить только один провод (плюсовой, например). вольтметр показывает напряжение 0 между BUS+ и BUS-.
