3DR Solo iMX6 as video and telemetry link

3DR Solo, have a great onboard computer, the IMX6 runs Yocto Linux : link to the Linux source: https://github.com/OpenSolo/imx6-linux Among it s best features is the HDMI-in, USB, and mini-PCIe port which can easily use rather powerful MicroTik router/Wi-Fi modules. I reverse-engineered the remaining pins, as only the 3 and 6 pin headers were known to Continue reading 3DR Solo iMX6 as video and…

BMSOne – the universal BMS

This product is discontinued. Version2 is here: https://madhacker.org/bmsone-2-universal-2s-6s-bms-for-ardupilot/ This BMS is very flexible and universal, you can fly any 4-cell battery chemistry/capacity that the Solo can handle in terms of voltage weight, anything that produces 10-20v(I did not actually research/test Solo s upper voltage limit) The PCB is less than 50x40x9mm (the balancing…

FLIR One: USB-C and battery mod.

FLIR ONE is a nice product, with an extremely limiting battery and bad software. (Luckily, third-party software is much better) You may say the battery has two reasons to be there:1: Limit useful time: pushing users to a more expensive product.2: Obsolescence by design: become useless as the battery age and stops working. Goals:1: remove Continue reading FLIR One: USB-C and battery mod.

Solo/Ardupilot SMBUS BMS

Latest progress: See https://madhacker.org/bmsone/ the resulting product. 13 January 2020: It s working as expected. (The balancing connector header had 2mm pitch on PCB (my bad), therefore, this test version got a wire.) All Calibration/setup/programming and firmware updates are done over the FTDI header. Please do not think much about the poor flight time I Continue reading Solo/Ardupilot SMBUS…

SW-LD73 Laser driver modification.

This laser driver board seems to be common for many 20W LED lasers used for cutting/engraving. Whenever powered on, it defaults to full power due to a rather strong internal pull-up. Most CNC machines have a laser TTL PWM output that goes into high-impedance mode on boot. In that case, any connection to, or reboot Continue reading SW-LD73 Laser driver modification.
