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 →
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 →
UPDATE : Raspberry Pi CNC Challenge Update Hi everyone… I’m looking for help here. I am trying to improve the Raspberry Pi CNC board. I am willing to give away 10 pre-released Raspberry Pi CNC boards with the following new features:
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 →

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 →
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.

I have used Python on and off over the last year or so and keep getting surprised how versatile the programming language is. From the start I have accepted that it’s a scripting language and always used a normal text editor with the hope of someday being able to develop in a proper Integrated Development … Read More →
