"Tell the chef, the beer is on me."
We’ve posted before about our tinkering around with Ebikes. One of our members had a faulty Ebike battery. Opening it up, the battery management circuit was found to be toast. We sourced a new one online from China, fitted it, and the battery is back up and running. We are thinking of making some spare batteries from old laptop batteries. We’re also thinking of having a TOG loaner Ebike. If you have any old laptop batteries that you could donate to us, we’d be interested. If you’d like to take a look at our Ebike works, drop in to our regular Monday evening Electronics night.
Summer is coming, that means our favorite event is only months away. Dublin Maker is community run event, which will be held on Saturday July 22nd, 2017 in Merrion Square, Dublin. It takes the form of a festival style showcase of invention, creativity and resourcefulness, and a celebration of the maker movement. It’s a place where people show what they are making and share what they are learning. Now is your chance to take part, they have a call for all sorts of projects and ideas on their website.
To get an idea of whats it all about check out the playlist below from last year.
Tog is proud to be a partner of this wonderful event since its inception and we are looking forward to it.
The Goethe-Institut´s regional project Fading Memories are hosting a special screening of “Who am I” by Baran bo Odar in the IFI. Following the screening there will be a panel discussion with Renate Samson, Chief Executive of Big Brother Watch (London), Una Mullally, journalist and columnist with The Irish Times and William McLoughlin from TOG Dublin Hackerspace.
The screening will take place on Wednesday 5th April 2017. For tickets visit the IFI website.
HackBergen arrangerer vårens loddekurs
Alle får lage en krets som de får med seg når kurset er over. Du lærer ikke bare lodding, men også litt elektronikk og hvordan du kan teste kretser uten å lodde.
Kurset holdes på Bergen Offentlige Bibliotek i Verkstedet. Verkstedet er i 2. etasje bak amfiet i Urom. Vi starter klokken 11 og gir oss ca kl 15.
Vi stiller med nødvendig utstyr og verktøy.
Deltagere under 16 år må ha med seg en voksen, som også må delta på kurset.
Meld dere på her: https://www.deltager.no/loddekurs_01042017
Tonight at NERP, Elias Bakken of Intelligent Agent AS and Thing-printer, in Oslo, Norway, will tell us about the Replicape rev B. [http://wiki.thing-printer.com/index.php?title=Replicape_rev_B]
“Replicape is a high end 3D-printer electronics package in the form of
a Cape that can be placed on a BeagleBone Black. This page is about
the Major revision B. It has five high power and low noise stepper
motors with cool running MosFets and it has been designed to fit in
small spaces without active cooling and without the need for physical
access to the board once installed. That means no potentiometers to
trim or switches to flip.”
NERP is not exclusively Raspberry Pi, the small computer and embedded systems interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago. Find NERP and Pumping Station:One at
Doors open at 6:30pm. NERP is free and open to the public. Ed Bennett ed @ kinetics and electronics com Tags: electronics, embedded, NERP, Open Source, raspberry pi, hackerspace, Beagle Bone, Pumping Station One
If you’re not familiar with the Power Racing Series, it’s a challenge to build and race an electric vehicle. You start with a Power Wheels car and transform it into a powerful machine that can transport a human, and oh yeah, you have a budget of only $500. (Pictured above is a car made by some 15 year old kids a few years ago for Maker Faire Detroit!)
You can find super-cheap (and even free) used Power Wheels cars on craigslist, and usually the batteries are dead and there’s no charger, which doesn’t matter, because we replace all that with more powerful motors, batteries, motor controllers, brakes, etc.
One of the goals of the series has been to get high school age kids involved, but some of the skills needed to build a car may be out of reach of your local high school, such as working with metal. Welding equipment may not be available, and mentors may not have metalworking skills, so we wanted to develop a reference vehicle that uses no welding. We chose to mainly work with wood for our build, but check out the “no-weld car” wiki page for some other builds…
Here’s the start of our frame. It’s all wood, glue, and screws. We’ve utilized a torsion box design for strength. So far we’ve only used a saw, drill, and some clamps. No specialty tools that are out of the reach of your common workshop. We’ve got a long way to go, but we’re going to try to make this car super-cheap, and easy to build, so that many teams (of kids and/or adults) could easily build it. As members of a makerspace, we may tend to forget that not everyone has access to the tools and skills we do.
We’re also working on front wheel spindles build using wood and bolts. Yes, you can buy metal spindles for cheap, but a lot of what we are doing is experimenting with materials and geometry, which should provide some valuable lessons along the way, and it should be cheap/easy to modify things, try-test-try again, and see what the outcome is.
For years, our makerspace has used a hodgepodge of solutions for storing members’ projects in progress and other personal belongings. Most recently, we’ve used a dozen or so plastic totes. The totes worked great, but were limited in quantity (they were industrial waste, and no more matching totes were available) so that not everyone could have one. Additionally, these totes were slightly trapezoidal, which wasted quite a bit of space between them.
To that end, Ben and Kevin undertook a project to convert personal storage to standard Letter/Legal Banker’s Boxes, which are readily available and pack more densely. They are a bit smaller than the totes we were using, but most members totes weren’t full, and we can store twice as many boxes in the same space.
Read on for full plans and assembly instructions.
Ben’s initial sketch was nothing fancy, so he drew it up in Sketchup, and developed a full cutting plan. The entire shelving unit is 2 sheets of 23/32″ plywood and 2 sheets of 1/8″ MDF, both readily available at the local home improvement store.
The instructions below are split into “cutting” and “assembly”. Without going into painful detail, you’re going to need some power tools to make this project happen. We used a table saw with a dado stack, a circular saw, an air nailer, and a router with flush trim bit, among other things. You could certainly get by with less, but these plans were made and instructions written given the tools we had available. Without further ado, the instructions.
First, using a circular saw and straight-edge (if your table saw setup is big enough to make these cuts, go for it, but you probably don’t need my instructions – just print the cut list and have at it).
Next, set the table saw fence to 15-7/8″. Once this is set, don’t move it until absolutely necessary – we’ll be switching around between tools for a bit, but when we come back to the table saw, we’ll want our parts to be exactly this same length.
Next, go back to the circular saw and cut the conjoined shelves from Sheet 1 to 42-3/4″ length.
Mount a 23/32″ or 3/4″ bit in the router and set the cut depth to 1/4″. Cut the grooves across the side panels every 12-1/4″, starting with the bottom of the first groove 4″ from one end of the panels. This end is now the bottom.
Back to the table saw, still set to 15-7/8″, and rip the side panels to their final width. We’re finally done with this fence setting.
Now use the table saw to cut the divider panels to their final 11-3/4″ height.
Now we need to cut 1/8″ wide, 1/8″ deep dados in the shelves, starting 14-1/4″ in from each end. Six middle shelves will be grooved on both sides, but the top and bottom shelves only need grooves on one side. We can do this with a 1/8″ kerf blade in a table saw, using a miter gauge to support the parts, or with a router and a 1/8″ bit. The router is probably the safer option, but those tiny router bits are expensive, fragile, and slow.
After struggling with our old Dewalt bandsaw for the last year. We have finally taken the plunge and purchase a Startrite 301S bandsaw. We purchased it “not working” for a really good price, luckily we soon got it working. With a new blade this thing is amazing!

"Basically the price of a night on the town!"
"I'd love to help kickstart continued development! And 0 EUR/month really does make fiscal sense too... maybe I'll even get a shirt?" (there will be limited edition shirts for two and other goodies for each supporter as soon as we sold the 200)
