These are plastic razor blades made by Scraperite. They come with a little holder. And what these are good for is any task where you need to delicately scrape something off of a surface that you don’t want to scratch up with conventional razor or palette knife.

This week on Maker Update, a MIDI compatible music box, alternative controller indie games at GDC, an Arduino for your knife, controlling your computer with zombie heads, free game developer software, and Hackspace issue 5. This week’s Cool Tool is the Makey Makey Kit.

The annual Game Developers Conference in San Francisco is a wonderfully outrageous, high tech fantasy land where corporations like Microsoft, Facebook, Sony and Google, hold court with their latest zombie-blasting simulators and VR headsets. But it has a secret.

Off in the back (technically in a whole separate building), away from the buzz and hustle of the main show floor, is a small cluster of 20 curated, one-of-a-kind games under a banner labeled “alt.ctrl”. Here, the creators of these games encourage people to come over and play their project. They call themselves Developers, but I see them as Makers like myself. People who take their fun from mixing equal parts Art and Engineering. 

This week on Maker Update, an automatic dice spinner, a desktop CT scanner, what taggers can teach us about permanent markers, and powering your Raspberry Pi from lithium iron phosphate. This week’s Cool Tool is the Krink K-70 Permanent Ink Marker.

This week on Maker Update, a mechanical hummingbird, the 2018 Hackaday Prize, a tour of Fab Lab Barcelona, casting metal from 3D prints, and getting started with Arduino without an Arduino. This week’s Cool Tools is 3M Virtua CCS Protective Eyewear.

Particle, the company behind the Internet of Things hardware and software platform of the same name, announced three new, low-cost development boards today that make use of mesh network technology. The Arduino-compatible development boards come with either a cellular (LTE/3G/2G) connection, Wi-Fi connection, or a mesh-only option. All three boards are also cable of communicating over Bluetooth Low Energy (BTLE).
