Just want to post a reminder that if you're on this instance and you're not into making the same types of things you see me post, that's ok. If you're making (or have made) a thing and want to share it, please feel free. I'll usually post things that are electronics or mechanics related, but I'm always interested in seeing the diverse things that makers create.
This has been years in the making. We're very proud to partner with @olimex, a company which makes open source hardware.
Sales launch soon. Order: https://www.olimex.com/Products/OLinuXino/Home-Server/Pioneer-FreedomBox-HSK/
@jmwright Not described is the high voltage source. I built a Cockcroft–Walton multiplier pictured here. It is many stages, driven by a switching power supply from NiCd batteries. Fast diodes are needed - 1N4000s won't cut it.
I got a nice (safe) arc from this. I sent this to my kid's school, but it spooked the teacher.

Avec une chute d'isolant fin et de la toile cirée récupérée, on fait ... un sac isotherme. Doublé en toile cirée et qui ferme avec des velcros. (Le sac est rouge, pas rose comme sur la photo) / With a drop of thin insulation and recovered oilcloth, we make... an isothermal bag. Lined with oilcloth and closed with velcro. (The bag is red, not pink as in the picture) #sewing #diy

Ubuntu Touch OTA-8 has been released.
Can't recommend it enough. PLEASE use this for your media:
OpenCAx project ideas for the 2019 Google Summer of Code. FreeCAD, BRL-CAD, OpenSCAD, Slic3r and LibreCAD are all involved.
You can 3D print a piece for the world record attempt at the largest 3D printed duck.
This container is for use in working with a terrific new material that I am investigating: a mixture of chopped glass, sodium silicate, and water (more on this in a later post). This mix tends to get lumpy when mixed. I like to press out the lumps to create a more homogeneous mixture. This strong, flat-bottomed container will work well for that.
I created the flat-bottomed, straight-walled container from stainless steel. I used a carbide-infused fiberglass cutting disk mounted to a Dremel for both tasks.
All-State 11 FC Nickel-Silver coated brazing rods seemed like just the ticket, but it didn't work. Finally, I called the local Air Gas (where I get my gas cylinders) who sold me Radnor Safety-Silv 56 coated brazing rods. 😀 I used a natural gas-oxygen torch.

Makerdon is a Mastodon instance focused on Makers, Open Source Hardware (OSHW) and STEM/STEAM. Free and Open Source Software (FOSS) is a likely topic as well. If you're interested in making things, allowing others to build on your work, and/or teaching others about making things, you might like this instance.
