Building a Beautystar/Topdirect CNC DIY Router Engraving Machine PCB Milling Machine CNC Wood Metal Carving Mini Engraving Router PVC

Here we will discuss how to build these inexpensive CNC test/hobby machines which seem to be sold by different companies but look pretty much the same.  I add pictures and add explanations in addition to the assembly instructions found on a USB stick. The Instructions are a bit funny as you will find instructions in both Chinese and badly translated English, overlapped in boxes on pictures. There are also instructions to build a Woodpecker CNC, which seems not to be this product. The instructions are fairly accurate but sometimes the boxes are badly sized so you don’t see all of the text or the part looks different, or is mirrored while you are instructed to watch the orientation.

Building an ANTBOT Part 1 (the robot basics) to get the motors running

The Insect Robotics Group at Edinburgh University published a partly defunct plan  (No sources and incomplete building instructions) to build an ANTBOT.

I thought I nevertheless give it a go and see where I end up. The whole guide is practical and not intended to communicate endless theory that can be found elsewhere. What we want to achieve here are the minimal requirements to get the robot chassis going.

Seville 2009 Habitat3D data set as GPU Render

After having a look into Insect Robotics, I came over the Seville 2009 data set of an ant habitat (Cataglyphis velox).  Converting this with Meshlab and using a generic ant model with some freely available HDRI’s, resulted in some nice pictures in OTOY’s Octane 3.06  to visualise an ant perspective.

There is also a MATLAB representation on http://www.insectvision.org/walking-insects/antnavigationchallenge

Clyde Estuary Time Lapse 23.4.2016 – 3.6.2016

Using the techniques mentioned on this site [UCAM Sending] I made a time lapse video of the Clyde Estuary in full HD using 59650 single images using avconf.

First the webcam plays the image on my server, then the Continue reading Clyde Estuary Time Lapse 23.4.2016 – 3.6.2016
