  2. MacGyver engineering with at Brussels Airport. Charging a Baofeng with duty-free material only. Pencil lead as current limiting resistor, pencil sharpener blade as wire stripper. Two USB powerbanks in series to get 10V, USB power monitor as amp-meter

    Can probably squeeze out a little more simply by populating the matching network.

    First results look pretty ok. Currently testing SF 7 with 125 kHz bandwidth @ 10 dBm PEP. Getting a range of around 3.7 km from indoors. Can't do any proper outdoor test today but a first quick test from the back of my car yesterday suggests a max range of ~9.5 km

    Gets quite a bit better with some hand effect though. Setup right now might actually be comparable to the real world usecase

    Soldering in the largest battery I scoped out for the design yields significantly worse results

    Very easy to get it to 868 MHz with a little scraping. VSWR and S11 aint looking too bad either

    Currently designing a small MPPT solar charger to go along with it. Maybe I can turn this into a little solar powered environmental sensor platform or something. Guess CPU + communication board is next. Will probably be ESP32 based and have a LoRa radio.

    Designed a small 4s Li-Ion BMS to acquaint myself with TI battery gauges. The gauge can provide lots of interesting data on the batteries, but at first glance the configuration software looks pretty intimidating. Think I've got everything dialed in correctly by now though.

    Just finished building 's Otter-Iron, a PCB for converting the famous TS100 into a USB-C PD powered soldering iron. Will be absolutely awesome for soldering on the go since I can now power my soldering iron from a normal USB-C PD power bank!

    Spent the evening adding a fbdev frontend to shoreline. Now I can run a Pixelflut server on an EasyBox 904 xDSL (in glorious 320x240). Pixelflut all the things!

    First time ever soldering 0.4 mm pitch BGA components. Turns out it is really easy! Got 3/3 boards working first try.
