Photo of the week; Hack out of necessity

Out of necessity one of Hacklab’s members had to replace his pedal due to it literally falling apart leaving a stub, if he did not he would not make it to open house in time.
The new pedals that where picked up were the wrong size, so the only logical thing to do was to build a replacement pedal seeing as the stub of the former pedal was still good.
The new pedal functions fairly well but will need to be replaced or reworked for a smoother usage, and needs a little oil. The final pedal has been finished off with a coating of linseed oil that has been rubbed into it.

Mixology. A personal bartender.

Drink Mixer at your service.

Drink Mixer at your service.

Recently one of our members decided that he would create a personal bartender in a form of a Droid bartender. This handy piece of equipment is functional and makes a great conversation piece. The bar bot is named Luma-Droid and mixes some mean drinks. Not all of these drink need to be alcohol, I am sure this Droid can can mix a mean punch as well. This handy Droid uses 4 different liquid sources to mix from 6 different drinks pre-determined  programmed and dispenses at a push of one of the illuminated buttons. This is actually the second version of this little Droid. The first version did not have the ultra sonic humidifier that creates a further finished and polished look. But not every improvement is merely aesthetic. Many times when creating a project that delves into areas that is a first for anyone,  creates problems and a list of things you would do differently if provided a chance. Well Eric had the chance and in the second version shown in the photos, the ultrasonic humidifier was added, as well as new pumps, reservoir for the humidifier, and for good measure a extra layer of sealing to ensure the water proofing.

Hacklab at Digifest

by on May.16, 2014, under Events

Hacklab.TO had a booth at digifest for the family day exhibition – it actually felt a lot like a mini maker faire, with most our usual friends in attendance (hi makerkids, toronto tool library, techknight, getyourboton etc). We showed off a variety of member projects, including crowd-favorite Flipdot Game of Snake, some 3D printed objects, and some electronic jewelry. Looked to be about 1000 people through over the course of the day, check out my flickr gallery: digifest 2014

Cut and Sew.

by on May.07, 2014, under Projects, Unpatched Tuesdays

Several Months ago, a class mate approached me regarding a class assignment.
This is not an unusual for students to do to each other, but the subject was lasers and cutting services and where to find them.
I provided her with a few resources, and also mentioned work had one.
One thing lead to another and Several weeks later I received some Cad drawings to process for laser cutting.
The project that I assisted her with was a tailoring assignment, cutting fabric for various embellishments.
I do have to note that some photos have been cropped down to a quarter of the original size due to respecting her intellectual property, and artistic property.

Problems arise when the paper towel becomes completely dry. The possibility of flame ups in this case is increased.

Over the last few weeks there has been some rising use of the lathe.
Here are a few photos from some of the work going on.

Photo of the week; Out of this world.

by on Mar.09, 2014, under Projects, Running a Hacker Space, Unpatched Tuesdays

Eric wearing a flight suit.

Recently, one of our members surprised us all by showing up to the lab with a flight suit.

As the title of today’s post reads. This post is a little out of this world. Recently, one of lab’s members surprised us all by showing up to the lab with a flight suit he had obtained. We were all a little curious about its origins and the patches upon the suit. It turned out that the Ontario Science Centre had decommissioned this suit and this lucky member had been on a tour of the Science Centre at the right time to receive it. The patches on the uniform are a bit revealing. All of them seem to be authentic and telling as well.

The patch on the right side is from the Challenger Shuttle Mission in 1986.  I think this has been a little gem the Science Centre has had for many years. To include mission badges from such a tragic mission that ended in the loss of the entire crew on a flight suit that was meant to help educate and teach science has been a touching tribute. A tribute that has allowed the ideas of exploration and those who have been lost in its pursuit to be still part of it. Now the flight suit lives on with a member of our own exploration community. I hope that it can still help foster ideas of exploration, learning, curiosity, and education with its new owner.

Photo of the week: Fire and Ice.

by on Feb.26, 2014, under Projects

During the winter one of the members tried carving ice with the laser, with the intent to capture a little bit of Game of Thrones in ice.
This may sound both a great idea and a bad idea at the same time. The act of doing some test cutting proved this task to be more difficult than previously thought. Below you can see the results of the test cuts. The challenge was not water inside the laser, that was a simple challenge to overcome by adding a reservoir for any water that was melted and a mesh to keep the ice out of the water. The challenge with this came to be the laser itself. The power of the laser on the ice is just a bit too much for this job. This experiment became a practical demonstration of the effect of hot spots on ice in the Arctic.
The Laser is equal to the sun here, and when it heats up the ice enough for it to melt it basically creates a warm pool of water that melts the surrounding area of ice preventing any high resolution cutting. The more heated water the less of ice that remained. The laser job had to be stopped a few times to remove the excess water to achieve some of the quality of the cut in the second photo.

During the holiday break in December, I was able to print the below bracelet at the lab as a gift. The interesting aspect about this bracelet is that it is generated on-line allowing some customization and sizing for the individual. There is minimal clean up of the object once printed and the hinges work with no effort of cracking them or working them in. The hinges are quite an interesting design shaped in an oblong cylinder with corners that resemble chamfered ends. This shape provides contact to the printer bed without the use of support material and does not exceed the maximum print angle of an additive printer by a large margin. If you are interested in getting one of these visit n-e-r-v-o-u-s.com to customize your own bracelet.

Photo of the week: CT Surprise

by on Dec.20, 2013, under Unpatched Tuesdays

One of our members brought in a CT scan of a Kinder Surprise to show the lab one Tuesday evening, during open house.
Some of those lucky enough to be present this night had the unique chance to see what a CT scan looks like and learn about the process. The picture below provides a glimpse at the detail these machines can capture as well as the difficulties that can be encountered when trying to navigate the UI in the attempt to see around a proverbial and literal corner.  The photo described as view from top down is the top view looking at the imaging data. It is a little hard to distinguish what shape it is what as well as where one object starts and another ends. While in the second image a reference object is present in the foreground aiding the ability to distinguish shapes present in the background of the image within the CT scan imaging. This is why I said those who were present were lucky on that Tuesday evening, we were able to learn about and were provided a glimpse into what medical professionals may see and some of the difficulties they encounter when using visualisation technologies to identify and distinguish between objects.
