October 6th Main Library Meetup

We had our first indoor meetup in many years at the Main Library. For me (Lakota), this brought back nostalgia from the Wednesday meetups used to hold there in 2018. A small group of us found a quiet table on the third floor, and we had an enjoyable time. An opened cassette rewinder was brought for donation, and we were able to observe the intricacies of the internal mechanical parts. It is truly amazing how so many sets and layers of gears are required for a seemingly simple, yet delicate and precise task.

However, a major source of entertainment came from something very low-tech: a windup toy caterpillar from the dollar store. Kids’ cheap windup and battery-operated toys can contain useful and intriguing parts that can be hacked and repurposed for other projects. Sometimes, it’s just fun to open them up and see what’s inside.

Needless to say, we dissected a caterpillar for science at the library, and it worked properly when put back together. 🙂

Everyone ought to have a screwdriver or multi-tool on their person at all times. Nope, definitely no geeks at this table. 🙂 Photo courtesy of Diane Bruce.

We will have future meetups at different locations (some of our favorites from before the pandemic and potentially some new ones), but overall, this one was a blast.

Hack613 In-Person Meetups

With the COVID-19 pandemic rocking the world, our meetups up until last year had been entirely online over Zoom. Zoom proved and continues to be a useful resource for many people in the group, as it eliminates commuting from the various parts of Ottawa. Additionally, it has enabled the group to connect with other makers and robotics enthusiasts outside of Ottawa. For a time in 2020, we (consensually) Zoom-bombed a robotics club in Sheffield, England and had several laughs and interesting conversations. We’ve also had ongoing connections and virtual meetups with the Vancouver Robotics Club.

However, despite the benefits, we’ve had far fewer opportunities to capture fun memories and share them. Our website has been very quiet over the years as a result. In 2023, with the coming of summer, we began holding in-person meetups once a month at Britannia Park or Remic Rapids. They have been well attended and have helped to reinvigorate the spirit of our group. We did park meetups again this summer and in the colder months hope to continue meeting at least once a month in an indoor location.

Both online and in-person meetups have their advantages and disadvantages, so we aim to maintain this hybrid model into the future to accommodate the preferences of all in this unique maker community.

CNC613

CNC613 is a project to create a shared CNC machine. People can learn to use it and understand their needs and eventually elect to buy a machine or just use the shared machine. The exposure to the machine and community around it would lower the friction for people to buy or adopt this method of fabrication.

It was initiated by Darcy Whyte and the first machine was assembled by Doug Commons and Dave Hunt. A bit of help from Richard  Sloan.

We now have a great community of practice around CNC techniques.

Picnic and Space Program

We made some progress on the space program thanks to Steve (of rimstar.org). He made a complete apparatus for electrolysis. We learned a lot from it and it will affect our next steps.

I also flew my magnus glider but I’ve not got any pictures on that yet…

Picnic Pics

We had perfect weather yesterday. Ice cream cones and some running around in the park!

This park thing is really working out! There was even talk of doing this on some of the Wednesdays!

Last Sunday Meetup

Here are the pics from last Sunday!

Lakota is working on her locomotion robot project. Walter and I are working on a game based on movement that will use Arduino and accelerometers. We had other guests too!

Elgin

So back in the old days when we were running the Blink meetups Doug had this kit he made to introduce soldering and Arduino.

There was this one young lady who came and she was a bit reluctant to do the hands-on activity thinking it was too hard. Her name was Elgin. Doug and I insisted it was easy and she had a go at it.

She was ecstatic when the lights came on.

I came across her online yesterday.

She leads soldering and arduino type workshops in BC now and is a Masters Student in the School of Interactive Arts & Technology (SFU Vancouver).

Here’s a drawing robot she made.

I think it’s clear there is a great value in these walk-up activities!

Thanks Doug!
