Put me LDR & 10K resistor on and installed that firmware, the dimmer works a treat!

5. Download AVRdude from here: WinAVR | Free Development software downloads at SourceForge.net and install it.

7. Run Comand Prompt and type avrdude and press enter, should look like this:



8. type: avrdude -c usbtiny -p m168 -U flash:w:name of your firmware.hex
It should start loading the firmware.

The firmware will install from your root directory so if its C:\Users\YourName put the firmware there.

9. It should look like this if all is good:


It will beep when done, unplug the power and ISP cable from the clock PCB and install the tube then power the clock up and look at your new firmware!

I attached the firmwares i have in a .zip file.

My clock is working just fine now. Don't fix it if it ain't broke.

Thanks for writing that up!


How long does it take for the brightness to change?

Click to expand...

It changes in one second. You have just enough time to see the change.

Update:

Im no C programmer extraordinaire, but i did some mods to the firmware

Lol, that is a very personal clock

I see you installed the ldr, Did it work now ?

yeah the LDR works good!
