chance pi build

Hi Dan,
Your programmer is a clone of USBASP. So, you can use any software you want :
AVRDUDESS
EXTREME BURNER
ARDUINO (you can programm standalone chips with arduino software by Ctrl+Shift+u)
You can also use avrdude by command lines such as ; avrdude -c usbasp -p m328p -u -U flash:w:yourfirmware.hex

Regards

(ARDUINO (you can programm standalone chips with arduino software by Ctrl+Shift+u) would you mind explaining that a bit more thanks

v170 for ATmega8 and V301 for Atmega328 (still beta)

AVRDUDE likes slower AVR clocking then default one.
You should add software/config switch -B6 to slown down. It is most common clock setting

Hi,
The power supply is delivered by the programmer.
The interrupt is done by the rst pin of the 10 pins header.
I don't have any experience with mac but i'm sure someone here can help you with that...

Thanks reptooyep,

I would like to have software compatible with my personal iMac V10.11.6. Since my programmer is a V2.0 do I need to be careful what software I choose as well? Another question is can I program the ATmega while in the detector socket through the 10 pin header? If so, do I turn on the detector power and either give an interrupt command or is it automatic when the programmer is connected?

Thanks

Dan

Dantech,

What AVR programmer are you using for the Atmega8? I have the LCsoft Studio V2.0 USB to 10 pin hardware shown in post #91 of this thread. I am looking for compatible software for this device to program ATmega8 & ATmega328P chips.

Thanks,

Dan

The one is called USB ASP and it is compatible with AVR dude (controlled by console). GUI frontend is called AVR8-burn-O-mat. I use linux everywhere I can (I hate Microsh*t).

I saw AVR ASP on aliexpress for $3-4. This is quite popular programmer in europe and it is available locally

Dantech,

Sorry, R13 my mistake going from memory.


All of the posts in the Chance PI Coil thread in the COILS forum related to the Race Track 3DSS coil are as follows:

'Since this build has been going on for quite a while my posts on its construction are spread across several pages in this thread. Below are the post numbers in this thread that pertain to this build.

POST NUMBERS: 126, 134, 136, 138, 139, 142, 169, 173, 177, 179, 215, 216, 228, 229, 232, 236, 254, 255, 256, 257, 258, 262, 263.

Hopefully this will help to find construction details quickly.

Dan

Additionally the coil is 12.5" long by 4" wide to its midpoint. The coil is wound in the same fashion as the round version in the same thread on a slotted coil form having 37 slots on the outside perimeter and 37 slots on the inner perimeter but staggered to the midpoints of the outer slots...see photos. The coil measures 328uh in inductance.

Are you able to see the 1cm square aluminum from the side of a soft drink can with your original coil?

Not R1.
R9=470 near Q6. Sharp edges are critical in that circuit to make VDI stable and independent from signal strenght.

I did special release generating main pulses only (for ATmega8 to see coil ringing).
For dedicated coil R13=390 ohm and one is great. Ringing is visible above 500 ohm

I still do not have another coil than dedicated one.

Would you give me the size of your "racetrace" coil and winding scheme?
