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.
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.
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 🤷♂️
Le thème : les modèles de language et la robotique open hardware. Si ça vous intéresse de découvrir une autre facette que Skynet et la machine à billet,
We need #openhardware with #bluetooth so we can link them it to #MyGNUHealth.
Currently we have @pine64eu smartwatch, but we'd love to integrate scales, glucometers, blood pressure monitors...
Just reply to this toot or send us a message if you know of any device. We'd love to test them!🤗 #GNU#GNUHealth#pinephone#PineTime
"While companies like Framework and #Fairphone have been good at being transparent by providing repair information and access.., they are unable to be completely open when it comes to the hardware. One.. reason for this is the reliance on a hardware supply chain peppered with NDAs. One company that takes a.. different approach to that is MNT Research." 💪 @mntmnhttps://www.ifixit.com/News/94927/how-open-hardware-empowers-users#OpenHardware
It seems to have happened without much fanfare, but about a month ago @purism has released the Librem 5 hardware layouts under GPLv3 (as original PADS and converted KiCad projects), joining the schematics that were already available from the start.
Has anyone come across any information design research project/group/community which makes infographics of supply chains of the making/manufacturing behind really complex biomedical devices like MRI and drug manufacturing, testing equipments like spectrometers, chromatographs?
With the aim of documenting everything necessary in order to make #openhardware, #opensource alternatives to them?
"#Tangara is a portable #musicplayer. It outputs high-quality sound through a 3.5 mm headphone jack or Bluetooth, has great battery life, and includes a processor that’s powerful enough to support any audio format you can throw at it. It’s also 100% #openhardware running #opensource software, which makes it easy to customize, #repair, and upgrade. Tangara plays what you want to hear, however you want to hear it." https://www.crowdsupply.com/cool-tech-zone/tangara
Join us in less than an hour for a tech talk with Andrew "bunnie" Huang. He's currently working on IRIS: (Infra-Red, In-Situ) inspection of silicon, a project to facilitate the non-destructive verification of silicon chips.
There will be lots of time for questions and comments as he is interested to hear peoples' thoughts about IRIS.
Andrew "bunnie" Huang will give a webinar about his project IRIS (Infra-Red, In-Situ) inspection of silicon. A project to facilitate the non-destructive verification of silicon chips.
He'll give a short talk about the project but will leave most of the time for a Q&A as he is interested to hear what people think about IRIS.
Bunnie is an open hardware hacker, and an activist for digital rights.
Join us Thursday May 2, 11.00 CEST. https://nlnet.nl/events/20240502/index.html
Everyone is welcome to our two upcoming open hardware webinars:
Open source CPU and SoC design: The flow, the challenges and a perspective, with SpinalHDL creator Charles Papon on April 11, 13.00 CEST.
And a Tech Talk with Andrew "bunnie" Huang on IRIS: an open hardware project to verify chips. May 2, 11.00 CEST.
An interactive talk with hardware hacker bunnie on his project IRIS (Infra-Red, In-Situ) inspection of silicon.
Anyone seen a free hardware design of a small PCB that adapts 50pin SCSI (host side) to 68 and 80pins (drive side), including termination of the upper 8 bits?
Without this termination, many drives run unreliable on older computers.
Yes, BlueSCSI, ZuluSCSI and RaSCSI exist. We do use these. But we have plenty of 80pin drives, and these are more appropriate for an SGI or HP 9000 – including the sound & feel (clickety-clack).
