My latest blog post: Hacking an IKEA HÖVOLM into a Helmet Rack

https://mikecoats.com/hovolm-helmet-rack/

I received my first ever 3D printer as a present recently, so I decided to put it to some practical use. I designed some new hooks to hold bike helmets securely on an IKEA HÖVOLM.

OpenFlexure is an open source laboratory-grade microscope used to diagnose malaria and cancer. In this interview Julian Stirling, one of the core developers, tells us how the project evolved from its academic roots to a diverse community of people who use it, build it, sell it, teach it & develop it.
OpenFlexure is manufactured in many places to build local capacity. The next step is medical device certification, a slow but worthwhile process.

Europe has a unicorn obsession, and frankly it needs to stop.

The EU is pouring €43 billion through the CHIPS act into creating "European champions," but we're missing the bigger picture: why are we treating essential tech infrastructure as private property instead of public commons?

We need a different approach. One that serves public benefit over private extraction. Read my thoughts here: https://tarakiyee.com/the-hardware-innovation-monopoly-problem-why-europe-should-stop-chasing-unicorns/

My Sensor Watch Pro just arrived!

Time to take apart my Casio wristwatch to install it! ...as soon as I can find my tiny philips screwdriver.

Curious how we program our two giant lasers?

Hier eine kleine Geschichte darüber, wie ich zum #MEGA65 kam, und was sich seitdem ereignete.

Viel Spaß beim Lesen!

Looking at schematics and #firmware of #Teufel #MYND waterproof portable speaker.

Very cool to check out their #OpenHardware design, though not much to see.

Everything of note runs through the WB-2835P #Bluetooth / Audio Module. It even acts as USB-Soundcard and digitizes Line-In, then outputs #I2S to the amplifier chips.
