Elecrow PCB’s Recently Elecrow provided the offer of $10 USD towards pcbs (Which can get one 5x5cm PCB shipped for free). The catch for this was to provide a review of the PCB and their service. I ordered two PCBs from this voucher, a yellow PCB that acts as an XT30 joiner board for setting up paralell connections between 3S batteries, and, a black PCB that is the top pcb on the openBMS project I’m slowly moving along on HackADay....

Review The TS100 is possibly the best soldering iron I have used for under $200. It is very lightweight and portable, runs off a wide range of power sources and has full PID temperature control built in. The built in accelerometer provides a protective sleep mode to prolong the length of your tip. With the 65W power rating, it heats to 360 Celsius in under 8 Seconds. Main Features 65W rated output (24V Input)....
This is a public release of this design, created in KiCad. This board will plug on top of a Pi Zero and provide 3 SD cards (1x SDIO, 2x SPI) and an audio output DAC with headphone driver. This was originally designed for a prototype Audio player / streaming setup. This is a cutdown version omitting some power and misc components that are no longer required. The board could be re-routed to be smaller, however I feel releasing the tested version is a better idea....
Notes of setting up SeaFile under docker on Ubuntu Server 16.04 LTS I have recently started using SeaFile to provide an easy method of centralized file storage. Trying the normal install with the installation script kept failing (Appears to not support latest version). As I am aiming for an easy install for others I looked to the docker based image. I use docker for packaging up other servers I often use, so this seems like a natural and easy way to work....
