MO-BB-advancedUpdating the breadboard with the components for the final schematic of the Mighty Ohm – Wifi Radio.

Again, first power it up and check if the 16×2 lcd displays any text (it should) before hooking it up to the asus 520 router.

To the left the usbTiny is shown with the 6-pin ISP cable disconnected. It’s easier to work on the breadboard this way and I don’t want to remove the patching of the other end of the cable into the bradboard just yet. A little breakout board would be handy for this. Maybe I’ll build one. If so I’ll share it with you.

Just above the usbTiny you see three wires in a loop. These are the TX RX and GND that need to be connected to serial pin connector on the asus 520 router.


Comments Comments Off on Mighty Ohm โ€“ Wifi Radio: breadboard 2

While modding the Asus WL-520GU router into a wifi radio it’s time to bring out the breadboard.The schematic on a breadboard Interested in the project? Look here at Mighty Ohm.

After flashing the Atmega168 with the usbTiny the first phase would be to see if I can get some text on the display. I found a helpfull comment on the Mighty Ohm forums that, without actually attaching the breadboard to the asus 520, there will be text visible on the 16×2 lcd display.

Power is supplied through the usbTiny 6-pin ISP that is still hooked up since flashing the microcontroller.

After a first scare of seeing nothing I realise that the potmeter just might need a little turn. That was it! Text appeared on the display without further connections.

Note: this is the intial schematic on the breadboard. The final schematic of the project has more functionality and a few more components.
