The B3603 is an affordable constant current or constant voltage DC to DC converter. I works great as a bench top power supply and takes 6-40VDC in and delivers 0-36VDC up to 3A. Accuracy is also pretty good. As a side project a few people have been looking at writing alternative firmware for it. EEVBLOG … Read More →

NANO-ARM : Arduino Zero Compatible but in Arduino Nano Form Factor
We loved Arduino Nano’s but always wanted a bit more performance and memory. So we decided to create a Arduino Nano compatible board but with an upgrade micro-controller that is similar to an Arduino Zero. They are now ready and shipping from our online store : Protoneer Online Store http://wiki.protoneer.co.nz/NANO-ARM Nano-ARM forum page
Electric Cars Vs future of the Nurburg Ring
I am “quietly” enjoying the future of automobiles. Serious I love the sound the next generation of speeding cars are making…. The NextEV Nio EP9 is a stunning example of where we are heading. +1300HP from zero RPM. 0-200KM/h in under 8 seconds!!! It started with Formula E and they have now moved into the … Read More →
Raspberry Pi CNC Challenge – Update
First of all thank you to all who responded to the Raspberry Pi CNC challenge. We received plenty of emails with amazing projects. Entries closed on the weekend and it was pretty hard to pick. Congratulations to the following people. Your boards will be on their way in the next few days… Charles Taylor … Read More →
GRBL’s PWM functionality – How to control a laser or variable speed spindle.
As of Version 0.9, GRBL supports PWM for controlling variable spindles and lasers. (Both our Arduino CNC shield(V3.10+) and Raspberry Pi CNC Boards support the PWM functionality. ) To use the functionality there are two parts to look at. The first part is the way GRBL firmware is set up when compiled. Luckily most of … Read More →
Vagrant makes it easy to use mBed GCC Toolchains
I am a great fan of Automation and with my recent venture into Hardware manufacturing( + limited resources) the need for automation has been highlighted. In a previous post I explained how to deploy firmware to hundreds of Micro-controllers with a simple script. My next adventure is with Toolchains. Toolchains are the software utilities/tools needed … Read More →
Arduino CNC Shield – 100% GRBL Compatable
Do it yourself CNC projects are popping up everywhere and we decided that we wanted to contribute to the growth. Here are a few of our design goals: Modular Design – We wanted to do more than just keep cost down. We wanted things to be reusable and up-gradable. (Arduino , Individual Stepper Motor Drivers and … Read More →
3D Printing Cars reduces environmental impact.
Quick preview of how easy it would be to assemble a modular car frame. By using more efficient materials like light-weight carbon-fiber tubing, it reduces manufacturing cost by using less energy to ship raw materials.
