Schematic questions, also one about the firmware

[danrulz12]

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

What schematic you mean?
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.

Sorry, i should have been more specific. I want to know C1 from the emulator schematic, and C7 from the power supply schematic. Also i'm afraid i don't know what L1 from the power supply is, im not very experienced. Is it apart of the transformer? Thankyou for your previous responses.

C1 - 47 microFarad electrolitic capacitor
C7 - 0.01 microFarad - 10 nanoFarad capacitor
L1 - any regular inductor

Would it be possible to use this power supply ( http://www.powerstream.com/dc6.htm ) or this one ( http://www.powerstream.com/dda.htm )and adapt it to have and on/off input? If i could adapt how would i do it? Is it necessery, could i just connect it to a switched 12v source thats controlled by the vehicle key? Thankyou for all your help so far

Maybe. I don't know how you can adapt on/off input.
