| | | | | Raspberry Pis are great little computers. Wonderful for running hobby services. But, whenever I start a new RPi project, I dislike needing to dig out my spare HDMI monitor and USB keyboard. I don't like having to take up room, connect all that hardware, just to enable SSH and Wifi so I don't need any of that equipment I just finished setting up. | |

| | | | | QO-100, also known as Es'hail-2 is a geostationary amateur radio satellite. It can be used by large parts of the world, including Europe, Africa, (parts of) South America and Asia. The satellite works as a linear transponder. It receives a specific range in the 2.4 GHz (13cm) band and sends it back to earth on 10 GHz (3cm). In order to generate such a 2.4 GHz signal and transmit it to the satellite conventional radio technology with transverters could be used. I chose a different route and planned a fully software-defined setup. This has many advantages: - Cost (PlutoSDRs can be bought for ~120?) - Low power consumption (laptop, SDR, amplifiers), ideal for portable usage - No SSB transceiver needed - Software DSP processing for very clean signals - I/Q sampl... | |

| | | Wednesday, after some weeks with a flickering screen (or more precisely, something is causing GTK+ to redraw and the kernel to print ^@ in the terminal when you touch the screen, see http://jak-linux.org/tmp/20100628_002.mp4) in my 3 years old HP Compaq 6720s (which seems to be a software-hardware combination problem, at least it works in Ubuntu); I decided to buy a new laptop. It took me a few minutes to find the Lenovo ThinkPad Edge 15 NVL7VGE; which I ordered at notebooksbilliger.de at around 14:30 CEST using Express. On Thursday morning at 6:40 CEST, the device arrived. | ||
