Title: Schematic questions, also one about the firmware Post by: danrulz12 on 13 Oct 2006, 14:22 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 Title: Re: Schematic questions, also one about the firmware Post by: Vitat on 13 Oct 2006, 15:49 Hello, i have a few questions about the schematics.

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.

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 capacitorC7 - 0.01 microFarad - 10 nanoFarad capacitor L1 - any regular inductor Title: Re: Schematic questions, also one about the firmware Post by: danrulz12 on 13 Oct 2006, 20:00 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

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