Asus – downloads

I needed a motherboard manual to sort out some USB headers. So rather than searching through all my files I went to Google on the laptop which took me straight to the product page on the Asus web site. To download anything Asus wanted to know what OS, so I […]


My main PC died today

I opened Firefox and it just went off and would not restart. The power supply has failed; seems it won’t supply the load. It’s a AMD dual core something-or-other, about 3GHz I think, 4G ram and a 1G low profile Asus ENGT220 video card on a Asus MB. Asus; that’s […]


433MHz RC development

The intended purpose is for RC control with telemetry of FPV and larger planes or multi-rotors. The link is two-way; RC control to the plane and telemetry back. With a GPS module plugged in at the plane, position, speed, altitude etc. can be returned in real time to  the transmitter. […]


Power Safety Cutoff

Low cost RC quality

Just A few notes: my impression of Chinese product quality Many people currently think of product from China as a knockoff and/or rubbish. I think this will change. I heard recently that China is patenting more stuff now than the rest of the world is. It doesn’t mean it’s good […]


Linux on an old Laptop

For some micro code development I wanted a simple serial terminal on another machine; something like Teraterm or Hyperterminal, but not windoze. I’ve had far too much trouble in the past with windoze and serial comms, and I want it to run USB to serial cables without fighting with stupid […]
