Having experienced some major WIFI problems over the years, with the overly crouded 2.4 ISM band. I decided to dust of the good old CC2500 chip, and get it running, properly. The reason for this chip? the 8-bit RSS value you can acquire from it. These day’s, the very cheap NRF24L01+ is rather nice, and cheap, but with a 1bit RSSI ‘threshold’, not very useful for these kind of setups.
A friend of mine was enjoying his Chinese UC40 projector, but for some strange reason, the manufacturer figured that it would be a nice feature to watermark the projected image. So he decided to upgrade this beamer with what turned out to be a incompatible image.
After a failed attempt (see my previous post) to re-gain access to my HP-probook 5310m laptop due to a bios pre-boot authentication, I decided to give it another go.
