Ahh the linksys was a 12v device, the wall wart i had was unregulated and the wires were rubbish.
The little stripboard daughter board in the pics is hosting an LM7805 to power the usb webcam thing because the wrt54g usb port itself was a bit of a hack https://wiki.dd-wrt.com/wiki/index.php/USB_mod_WRT54 https://wiki.dd-wrt.com/wiki/index.php/USB_mod_WRT54
- magicalhippo 6y agoAh yeah I was thinking about the article solution. If you need 12V at the device, I'd use a ~18-24V wall wart, laptop supply or similar with a DC-DC converter. The LM7805 works fine for low currents, but being a linear regulator wastes a lot of power which gets turned into heat once the current goes above 100mA or so.
