Quality engraving review

Engraving review K40 with Moshidraw engraving These engravings were done by someone else since I never got Moshidraw engraving to work on my machine and I really don’t want to reinstall the troublesome winseal, Moshidraw and the NanoM2 controller to find out that it does not work again. So, I can’t tell if these engravings are the best […]

Manufacturing an Arduino R4

  My journey with the Arduino PCB’s began a year ago when I purchased Chinese K40 Laser cutter and engraver from EBay which I upgraded with a Grbl controller based on the UNO R4. After experimenting with a stock Arduino UNO R3, I decided that I needed a better Arduino with at least one additional […]

PPA – other hobbyist particle accelerators

  Today’s blog celebrates others’ particle accelerators, through a series of youtube videos.  To get us started, let’s start with the real deal particle accelerators: overview of the LHC real homemade particle accelerator   Moving onto broadly similar hobbyist designs, Jo and I built our first particle accelerator without seeing these: Very basic accelerator Basic circular […]

Installing the K40 controller

Installing the R4 Controller Tools: All you need is a pair of pliers to cut one wire (optional), a screw driver to connect one wire and install the L shaped corner profile adapter for the opto coupler. Tips: Take photo’s of the existing NanoM2 board/endstop so you know what and how it was connected.   […]

PPA – Infrared Photogate Sensor (IRPS) design

An IRPS is required to provide ball position timings, so that the Arduino can precisely calculate the timing of a high power pulse to the electromagnet. The general concept of a photogate is that infrared light shines from a LED (transmitter) to a Phototransistor (receiver) all the time, except when the ball is travelling through and […]
