Beginners Welding course

Learning to Weld

I have been self teaching myself welding for a year or so. I picked up the cheapest entry level MIG (Clarke Pro 90 MIG Welder) off ebay and just went at it. Some other kind folks at Hackspace (Steve and Neil) showed me some arc (MMA = manual metal arc) and gave me some time on a proper MIG setup which made be realise how "Pro" has no place in the name of my Clarke Pro 90. So when another member (Barny) posted a Beginners and Improvers Welding course at Easton college I thought it would be a good idea to get some proper training and fun too. So this is what we learnt.

3D-Printed Prosthetic hand

3D-Printed Prosthetic hand

The Raptor hand is a design of prosthetic hand that can be printed on consumer grade 3d printers like the Ultimaker 2. Anyone can get the files from Thingiverse and make one. We didand were amazed by the reactions from kids and parents

The designer Jacky Wan explains the hand project to Norm from tested. Also shows a new design that has a cooler steampunk feel as well as some cool modifications like 3d printed temsioners that replace those pesky screws.

This is the difference a hand can make to a child

Shapeoko CNC router update #1

The Shapeoko uses a RAMPS shield which is intended to run the RepRap 3D printers. A cheap CNC shield is now available which is more suitable.
