He's created a kit that a farmer can fit to their existing spray boom; spray heads are only activated when the system sees a weed, which cuts herbicide use and costs dramatically.
For farm use, the hat is hard to destroy and easy to repair: inputs are clamped, it handles reverse polarity everything and ESD everywhere. It aims to be self-documenting and easy to understand.
It includes a PCA9685 PWM controller for PWM up to 2A/channel, because I figured this might be good for LED control. I don't recommend trying to PWM a spray solenoid; you will be having a bad day.
Had to order a new iPod classic as my current one seems to have the hold button broken on the motherboard after replacing it several times to try to fix it. Hopefully this will be the last iPod I have to buy since I ordered the Tangara. Between @mntmn and Tangara I can really start shifting to using open hardware in my daily life and this is a change I am so ready to embrace. wish I could use the Tangara before @defcon 🤷♂️
Linux kernel becoming their own CVE Numbering Authority (CNA) is wasting resources they'd have previously put towards higher quantity and quality backporting. We've noticed a drop in both for the stable/longterm branches and particularly Android Generic Kernel Image LTS branches.
