uRAD Monitor Flash Update

I recently received a firmware update for my uRAD Monitor so I thought I’d share my experience on it.

The new firmware adds a local web interface to few current stats as well as encryption back to the server.

You will need a ASP programmer that is capable of 3.3v, the firmware which you will have to request from Radu and avrdude for the flashing.

You can download avrdude from here.

I picked up a cheap ASP programmer from eBay for around ~$3 supporting both 5v and 3.3v.

Make sure the jumper is set for 3.3v.

I then pulled down my monitor and removed the two screws on the back of the unit:

Connected the programmer and powered it up, be careful as the orientation of the programmer may be different to mine!

Fired up a command prompt and avrdude to download the firmware to the flash:

Put the unit back together and reinstalled outside, after a few seconds the unit was back up and now responding with the new web interface:

Over all a pretty easy process, I look forward to future updates and am intending on building a weather station in the near future to be able to match weather data with the radiation data.
