That AVR JTAG ICE adapter works pretty well, but it’s annoying to having to flash new firmware to the programmer and then needing to customize avrdude in order to use it.
For the past 8 months or so I’ve been using a different flashing tool, basically just a USB to Serial TTL adapter paired with pymcuprog (instead of avrdude). It works very well and those USB to Serial adapters are dirt cheap and everywhere. See here and here for a few more details. I had been talking with Sofirn about putting together a flashing kit with this, but that conversation seems to have gone quiet, as I think it was going through Lux-Perpetua.
In other news Wurkkos has decided to use their current design of WK10 with aux leds and 14500 only. That’s an easy pass for me, for now this the only the Anduril AA/14500 light.
Since this project has finally become a reality and may have opened the door for more projects. I really want an updated SF11 with Anduril 2, parallel battery config of 4x AA or 14500 batteries and low vf led and of course an LT1 model based on SF11
Power and efficiency wouldn’t be very good with parallel AA configuration, in a single AA light there is no choice but with 4 cells in series the input would be 4V (Nimh) to 16.8V (li-ion), with theses voltages an efficient and powerful buck converter could be used.
The 519A only became the new hotness after Sofirn had started producing this light. It’ll take them a bit figure out that the LH351D is old and busted now.
Well, I bought 2 and used a coupon, $21 no battery, $23 with battery. Not bad. I’ll try it. I’ve been waiting for AA with Anduril a while. It was worth a shot. Too bad the flat magnetic caps are black. Also non removable magnets.
Surely they will offer the colors soon. You can kill your magnet with heat…hot soldering iron, small hot air tip, etc. Once you get them to around 80°C (for the usual grade) they will start to lose magnetism gradually and permanently…the higher you go the more is lost, and faster. At the curie temp (around 300°C I think) everything is gone for good. Can also try to break them up with a punch or cold chisel and remove pieces that way if you can get past any glue.
