Projection Mapping with the Raspberry Pi Workshop

unnamedAn introductory workshop where one could learn the possibilities and try out projection mapping with the Raspberry Pi. A full stack setup cycle demo will be presented. The following will be covered in a run-through manner.

  • Burning an SD card
  • Booting up and using ofxPiMapper
  • Using openFrameworks on the Pi
  • Creating custom generative source

The Raspberry Pi mini-computer is the perfect choice when one has to create a permanent projection mapping installation. OpenFrameworks makes it possible to create almost any kind of generative, data-driven or interactive applications that run on the Raspberry Pi and with the help of the ofxPiMapper it is also possible to projection map them.

Projection mapping is the art of texturing real-life objects by using a digital projector and specialised computer software.
Krisjanis Rijnieks ( works with creative coding, projection mapping and digital fabrication. He is developing the ofxPiMapper projection mapping addon for the openFrameworks creative coding toolkit, and using it in his own projects. He holds an MA in art and design from the Media Lab Helsinki and is the author of the book Cinder–Begin Creative Coding.

The workshop is a part of the Creative Museum project and in collaboration with the Chester Beatty Library.

Hardware Required

  • Raspberry Pi
  • SD Card for Raspberry Pi
  • Associated Cables


A Sign for Radiona

Last October, our own Jeffrey Roe visited Radiona, a makerspace in Zagreb,Croatia. While their he gave Skull Radio workshop and hung out in their space. As a thank you, we decided to make them a new sign for their door.  Taking a raster image from the Radiona website, we turned their logo into an SVG and made a sign. We went for a raised lettering effect with 3mm Plywood and using CF glue to stick the letters.

For photos of the build, check out our gallery.

DIY Vacuum Former

Last month Tog hosted Science Hack Day Dublin. A weekend where 80 makers took over the space to build all sorts of projects. A group of Tog members got together to make a home made vacuum former.

The idea came about while chatting on our IRC channel about what tools we should add next to our workshop. As just recently a got new CNC , we where looking for something we could build in a weekend and we landed on a vacuum former.

Starting off on the Saturday of the Hack Day, we formed a team to bring our idea to reality. After checking out some YouTube videos we formed a basic design.



Once we had the design, we slit the team up into three. One worked with the laser cutter to make the box. One worked with the CNC machine to make a frame to hold the plastic. Final the person worked with our electric oven to figure out the settings to melt the plastic.

Someone had the idea of drilling the holes by hand on the top of the box. Such a waste of time. So many holes we should just have laser cut them.


After a few hours all the parts where ready for our first test. It did not take us long to think of what our first object should be. A video of the inaugural us of the vacuum former is below.



Check out our gallery for photos of some of the things we have vac’ed.



Parts We Used

  • Cookworks Mini Oven
  • Shopvac
  • Lasercut Box (Download our design here)
  • CNC Frame (Download our design here rename to .dxf)
  • HIPS Plastic

November Open Social….with a twist!

mind-webBy now, you’ll probably know that we hold a regular Open Social evening on a Saturday in the middle of each month. November will be no different. We’ll be doing it on Saturday 19th November. This month however, there’ll be a bit of a twist!

We’ll also be hosting Science Hackday Dublin that weekend, so the space will be very busy. You’ll get to see up to 100 makers, up to all sorts of making antics, just for the pure hell of it!

If you’ve never been to our Social, you’ll find it a great alternative Saturday evening in town. Come in and look around. If you’ve never been in before, we’ll give you the grand tour of the space. Talk to members and visitors about projects or things you’d like to do. Ask about our regular craft evening, which has just restarted. See what the Science Hackday participants are up to. If you like what you see, ask about joining as a full member. Either way, we’re always interested to know what has drawn you to our door.

Hopefully there’ll be, caint, ceol agus craic as usual. The space stays open until the last member is left……usually the small hours of Sunday morning. The evening is free to attend for members and visitors alike. No need to book…. just turn up. You can drop in for 10 minutes, or stay the whole night. We have parking available. Bring beer, food, gadgets! Our doors are open from 7PM. Hope to see you there.

Visit the Science Hack Day website too, for more information about the event.

First cuts with TOG’s DIY CNC router


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.

Science Hackday Dublin 2016

Science HacScience Hack Day Dublink Day Dublin is a 36 hour hardware and software hackathon. A social event with creativity and love of science at its heart.  Each year it brings together coders, designers, scientists, engineers and makers simply to make interesting things. Why? For adventure, for playfulness, for science!  The event takes place on the 19th & 20th November.

This year we are super proud to be hosting the event in our own space. We have been helping out since the very first Science Hack Day many years ago. We are excited to offer a big range of tools and experience to all the participants. Now entering its 5th year, its the best community hackathon around.

Visit the Science Hack Day website for tickets.
