A Smaller, Cheaper RISC V Board

Early this year, the world of electronics saw something amazing. The RISC-V, the first Open Source microcontroller was implemented in silicon, and we got an Arduino-derived dev board in the form of the HiFive 1. The HiFive 1 is just a bit shy of mindblowing; it’s a very fast microcontroller that’s right up there with…

Workshop: Assembling the Tinusaur Kit in Varna, Bulgaria

This Saturday, September 2nd, we will have one day workshop for assembling the Tinusaur kits for those who supported our Indiegogo crowdfunding campaign. It will take place in Varna, Bulgaria, our host will be VarnaLab – the local hackerspace. We will learn the basics of electronic components, microcontrollers – ATtiny85 in particular and, of course, […]

OnChip Open-V Arduino Compatibility

OnChip has posted a Crowd Supply update on their plans for Arduino compatibility:

Open-V Arduino Compatibility

Arduino compatibility can mean a lot of things to a lot of different people, so we’ll try to be as concrete and specific as possible. For the Open-V, Arduino development tools, and interoperating on a hardware level with existing Arduino shields.

wire-bonds-zoomed_jpg_project-body.jpg

We’ve updated our live, web-streamed demos to include an Arduino mode in addition to the assembler and C modes we already have. You might also notice the relatively new Blockly modes and a refined layout of the demo page. Go write some code and see the results live streamed!

Learn, Teach and Make with the Tinusaur

Last week we’ve launched our Indiegogo crowdfunding campaign and, as of a few minutes ago, we’ve reached 1/3-rd of our goal already. In case you’re not familiar what the Tinusaur project is about … A small board with a tiny chip on it that comes as an assembly kit – a small package with parts and you […]

thingSoC Grovey on Crowd Supply

thingsoc_modelthingSoC is an Open Source socket system for IoT development and has just launched a new Crowdy Supply campaign:

thingSoC “Grovey”

Build any IoT or Networked device you can imagine!

c24rwnwveaaa4cm

The thingSoC Grovey! platform gives you the freedom to choose from hundreds of existing sensors, actuators, and radios to quickly create new electronic systems, in plug together configurations that were not possible before. Easily mix together different CPUs, Radios, and Peripherals, like Servos, Motors, Relays, Sound and Lights, and then program them in your choice of Integrated Development Environments (IDE).

The thingSoC Grovey! series combines access to the Seeedstudio Grove system, and the Mikrobus “Click” system, to give you the widest selection of radios, sensors, and actuators available today.

The thingSoC Grovey Series files are available on GitHub:
