First cuts with TOG’s DIY CNC router

img_20161101_201537

A few months ago we’ve mentioned a DIY build of a CNC router. The project turned out to be more complicated than we anticipated. The steel-based construction is not very forgiving, and the large size of the machine doesn’t help. Still, due to all the help from many members we managed to overcome a number of difficulties and do a few test engravings in MDF.

MDF is not a difficult material to mill – the most noticeable problems are the awful dust and the fluff around the edges of the cut.  The furry edge is easily fixed using sand paper, but the dust will probably require some more drastic measures in order to protect our lungs. Eventually we’re planning to cut and engrave a variety of materials, many of which have interesting properties but are incompatible with our laser cutter.

Visit us during one of our Monday CAD nights to see the new machine in action or in the video below.

We recently ran a Electronic “Build-It” Workshop. We have twelve build a line following robot. The little robot was an all analog device,  not an arduino insight. Check out the photos from the workshop in our gallery and the video below of them inaction.

Science Hack Day Badges

We love rockets around here, so when it came to creating this years Science Hack Day badge, we decided a new design was in order. We created a new rocket shape design for science champions to wear . A video of the process is below. If you would like badges created for a community event do get in touch with us laser@tog.ie

Tickets are still available for the upcoming Science Hack Day Dublin on the 14th / 15th of November.

Tech Week 2014 – Videos

On Thursday 1st May 2014, TOG hosted a night of talks for Tech Week. Nearly all the talks were recorded, and are on our YouTube Playlist. Apologies for the lighting in some, we are still finding our feet when it comes to videoing talks in TOG.

Introduction to Open Source by Rory McCann

How to pretend you know stuff about stuff by Sinead McDonald

Blender and the Creative Space by Jamie O’Leary

Spammers hate him! How one weird trick can keep your accounts secure online by Diarmaid McManus

The battery for the video camera ran out a few minutes into this talk.

Made It Aoife Crowley & Mary Plunkett
Unfortunately the battery in the video camera was empty, so this talk wasn’t recorded.

How to Build a Time Machine in 12 Easy Steps:

 

A Tachyonic Antitelephone is a theoretical device, a thought experiment from physics history which allows the user to send messages back to his or her own past using faster than light particles called tachyons. A while back I decided to build a receiver. Being a fine art graduate however and lacking all but the most basic knowledge of physics and electronics, I required more than a bit of help. For the benefit of my past self, I’ll now outline how it’s done so I can send this message back in time and know how to do it:
