3D modeling is a key tool in the maker toolkit and HackLab is full of makers who are skilled in the process.

Lawrence Temple, a longtime member of HackLab, taught a class this past August explaining the fundamentals of measuring the real world and using CAD software.

“In the maker community, there’s a lot of different ways that [3D modeling] can be used,” said Lawrence.

He mentioned three different uses of 3D modeling that are commonly deployed in HackLab; art, 3D printing, and machining.

“Anything that exists in three dimensions, you can model,” he said.

The first thing that Lawrence taught is how to measure things with precision. He spent an hour and a half of the three-hour class teaching participants how to use calipers to accurately measure objects in real life so that they can be recreated in a CAD program. Participants measured the dimensions of their cellphones and created models of them on their computers. Those models could then be used to create cases.

Lawrence, a software engineer by trade, wanted to get into 3D modeling to build a Gameboy Macro – a project where you modify a Nintendo DS Lite by breaking off the top screen, making it into a big Gameboy like device. He first learned how to model at the Fort York branch of the Toronto Public Library and then taught himself more using YouTube videos.

He spends some of his time at HackLab on his 3D modeling projects. He’s made a few different projects using the skills he has taught in the class, one of them being light fixtures, the results of which can be found in HackLab. The fixtures are thin-walled and clear, created in a vase style for aesthetic purposes. Through the design process he has been able to make different light diffraction patterns. His favourite fixture diffracts the light in a flame pattern.

From teaching the class Lawrence has learned that there are multiple ways to approach the same problem in design.

“You can basically approach [3D modeling] as many ways as you would draw a picture,” he said. “Some of it is intuition and some of it is tools.”

Over the next few months, we will be posting about the myriad of projects that people get up to at HackLab. Make sure to check back regularly for updates!

It can be hard to get information about social services in Toronto for people who are experiencing homelessness. They may not have regular access to the internet and pamphlets are notoriously easy to lose. Zach Donsky, a long-time member of HackLab, thought that there was a better way.

In 2018, Zach created Chalmers Cards, a set of wooden squares that have an abundance of important information laser-cut into them. They are tied together by an elastic hair tie that also makes it easy to attach to pants or a backpack and can be distributed by workers within the social services system. The cards can be easily and cheaply produced in maker spaces across the city and print files can be found on the project’s GitHub. It takes around three hours to make eight sets of cards and the materials cost around $1.

“Access to social services is not as easy as I think it should be,” said Zach.

Information is available online but is not often in the simplest terms. Most of the resources recorded on the Chalmers Cards are accessible through 24-hour toll free phone numbers. You can find contact numbers for TeleHealth, shelter referral, legal aid and more. Many people experiencing homelessness do not have regular access to computers or the internet, so phone numbers are often their best option for accessing services.

“A lot of social services documentation is available on the internet,” according to the Chalmers Card website. “But getting on the internet is a real chore when you don’t own a computer.”

The cards also contain brief guides on getting government identification and financial aid – no access to a computer required.

More than 1000 cards have been produced and distributed since the project was started.

Collaboration on the Retro Populator is still on going and some new progress photos can be found below. We have a new needle assembly, and have been doing minimum pressure testing to pick up components.
Additional news is that the Retro Populator has been announced as an semifinalist 1 of 50 top projects. In addition I learned earlier this week, that Hackaday.com featured the Retro Populator in an article post on there website.  Eric, Charles, Rob, myself, as well as Hacklab Toronto was mentioned in this post. Unfortunately Hackaday did not mention The Ultimate workshop and I hope they fix this issue soon. The Retro Populator is a collaboration and joint creative adventure between both Hacklab Toronto and The Ultimate Workshop. Both sharing resources, knowledge, and skills to create something that we hope others in turn will create there own enhancements for, and use it to create new technologies.

This years Mini Maker Faire in Toronto is over, but it was a grand success in my eyes.
People from all walks of life and age came out to explore, create, share ideas, and hack.
I believe the community just became a little bit bigger from this weekend, and a lot closer for those already in the community creating new connections and friendships.
I am hard at work combing through the photos, trying to decide what to do with them all.

I hope everyone had a blast this weekend and made memorys.
Here are a few moments I captured that I care to share.

This is the Droid you are looking for.

This weeks post is split into two, the first half is about a bearing made at the lab this week. The second half below the 4 photos from this week you will read about my adventures in Alberta and how I relate them to the community. This week  Atrain decided to outdo me and print a better bearing. If you frequent Hacklab, you may have played with the bright green printed bearing that is stiff and does not seem to be effective. Both of these bearings are open source, the bearing design is generated in OpenSCAD and is personalized to your printer. You can find the design on Thingiverse. Well Atrain did just that, went ahead and printed a bearing out of orange ABS on the Cupcake printer. The Cupcake is the oldest 3D printer the lab has, and of late it has been receiving quite a lot of TLC and some upgrades causing it now provide the Ultimaker with a bit of a competition. See the photos to see the great print quality, and the bearings in action.

I have been a little lax this month on posting new photos.  This has not been out of laziness, or the excuse there is simply no room on my camera. No, I have been away travelling around Alberta and volunteering at the annual  Canadian Institute for Theatre Technology conference (CITT). This year the conference was held in Calgary and while in town I took the chance when I had it to visit Protospace, Calgarys hacker space.                                 .

Moving Head fixture. This light on closer inspection is mainly built of stepper motors and controllers. The case contains atleast 9 stepper motors.

The CITT conference is an annual trade show for industry Representatives, Technicians, and more. Over the last few years of volunteering at the conference I have seen more DIY, RaspberryPI, Arduinos, 3D printing, and approaches to theatre discussed in a hacker and maker mindset. Theatre has always been a hacker and maker space, using little to no resources and lots of ingenuity, and usually little time.                          The diverse background of those in theatre, are possibly akin to those in the maker and hacker community.  Each person in a hackerspace has unique knowledge and skills. I forsee in the future theatre nestling or cuddling up to the maker community. The future should be an interesting one.

Tuning the newly assembled Series 1 3D printer, from Type A Machines.

As of late Tuesday night, HackLab is now the proud owner of a Series 1 3D printer, by Type A Machines. Leading to 5 members to tackle the construction, calibrations, initial tuning and testing of the printer. I expect throughout the following week the printer will be fine tuned and will settle in amongst the other printers we have in the lab.  I am sure we will be printing some add-ons for the Series 1 soon as well once the tuning is done, such as a tool rest and holder. We may even be adding LED lights to it to better see how the print job is adhering to the surface and see when problems are occurring in during the print job.                                                              I care to thank Type A Machines for the donation of the new printer, and care to extend an invitation to please stop by the lab during our Open House to see what we are creating with this amazing printer.

3D printers settling in to their new place in the lab.

At the rate we are building, working with, and utilizing 3D printers we may have to designate part of HackLab the Print Lab. I hope soon we can add the second Ultimaker we have been slowly repairing to our library of tools allowing more members to print at the same time and gain experience working with these tools. Thank you again Type A Machines for aiding to our creative, and educational tool library.

Hacklab the movie Exclusive still preview.

Todays post was originally suppose to be a comic strip that ended upon a past internet Meme which has recently been gracing the lab, specifically the LED sign.                                                               The Meme in question is the video of Rick Astley – Never Gonna Give You Up.  The LED sign just cant handle the current video this internet favourite, but I have high hopes for the video/animation currently in use with some more tweaking and editing it could be fully working in no time.                                         So instead of my intended comic I am present everyone with a mashup between a make your own caption, and what I am calling Hacklab the movie.
