Without a doubt the hardest piece of furniture I've ever made. Welded steel frame, top made from very old Tasmanian hardwood from a barn. Getting the angled legs right and just the amount of sanding/filing required to make it look all smooth took more hours than I can count. #woodwork #metalwork

New daily driver until I can find someone to fix my jammed Olympus OM-1. Canon AE-1 with a vintage Japanese analog light meter on top (internal light meter doesn’t work). The light meter is complete superfluous hipsterness considering I have meter apps on my phone but I like the process it creates.

The fact that I can impulsively get something printed out of stainless steel will never stop blowing my mind. AMAZE! Grace figurine from Project Hail Mary, 3D printed in stainless steel.

These were just taken with my iphone, hand held. I took a heap of photos with my tripod and DSLR but still need to sort them.

Final night in Tassie for our holiday last night, lying in bed at midnight about to sleep for our morning flight home, when my brother messages me and says “You still awake? Go outside”… and this is what we were met with… Aurora Australis.

Finally finished my micropython-powered pedestrian crossing lights. Currently has "timer mode" for kids to use as a trampoline timer and "manual mode" for me to toggle red/green as a workshop safety indicator when I'm welding/grinding and it's not safe to come in. obsoletenerd.com/making-old-p...

People keep competing for smaller and smaller mechanical keyboards. Here is my contribution... a Raspberry Pi Pico powered binary-chording 8-key keyboard where you play piano-style chords of binary values representing the ASCII table. This message may have taken an hour to type, but it works!

Hydroponic strawberries are flowering and have their first berries forming. Still manually controlling nutrient percentages but next step is to add automation there.

The plug was "rattling" inside, so I pulled it apart and all these pieces fell out. Internally the plastic pieces that hold the 240V prongs in place had all snapped off, leaving the prongs "floating around" with nothing else fixing them in place. These were barely used, just sitting running lamps.

I've now had 3 of these Mirabella Genio "smart plugs" fail in a very dangerous and scary way, over the last year or 2. Both have been in use in our home for a few years now, neither have been "abused" just used to schedule fish tank timers/lamps/etc. Details in thread.

Spent the last few weekends fabricating this steel bracket that connects to the factory CRT points in the Sega OutRun cabinet to mount modern monitors. The 3D printed VESA adapter lets you put any modern monitor in, and keeping the area behind empty of stands leaves plenty of space for the PC.

Tiny (<35mm to each side!) binary clock desk toy, using an ESP32-S3 and a GlowBit 4x4 RGB matrix. It checks the time using NTP then displays it in HH:MM columns, with the rows being binary values of 1/2/4/8 top to bottom.

Made a little grip-training thing that clips onto my home gym and lets me do climbing/grip training. Scrap metal plate with a welded loop on top, then designed mirrored holds in Blender and 3d printed them. It can be used in a few different ways to focus different muscles and grip types.

The sticker on the bottom of the keyboard. It says it was made in Taiwan, and all the chips inside say Made in Malaysia. No mention anywhere of this brand ever selling desktop PCs though, just keyboards and some laptops.

I found this old 8088-based PC at an e-waste place and can't find *any* information of its existence online. The only branding anywhere on the whole thing is on the keyboard, saying "Nan Tan Computer Co" and "NTC CO" but no reference of them building PCs, just keyboards. #retropc #retrocomputing

The world's smallest Canon DSLR remote shutter? Was mostly just curious how the pins work on the proprietary connector, with the ultimate plan of making an ESP32 remote-shutter for input-based triggering.

Why buy stickers when you can make stickers. Threw this together today at @ballarathackerspace.org.au using Inkscape and a vinyl plotter.

Nothing but the highest quality equipment in my workshop. Paint booth made from a camping gazebo, a spotlight zip-tied to the ceiling of it, and a heat gun hanging from some scrap wire. Worked great though!

Went out to support our school at the Energy Breakthrough race where kids race pedal-powered tadpole/reverse trikes. It's such a cool event and I loved seeing all the home-made trikes built by the kids. (The forged-carbon factory-built private school ones were a bit cringe though).

Progress on the Pico-8 arcade cabinet. Everything “works” and now it’s just about tidying up the documentation and the software installation process to make it more user friendly, and adding all the vinyl decals. #pico8 #ballarat #hackerspace #ballarathackerspace

PICO-8 arcade cabinet we've been working on at Ballarat Hackerspace. Far from a "Raspberry pi emulator and computer monitor" setup, this has a 1:1 native LED display suited to the PICO-8 resolution, custom graphics daemon to run PICO-8 natively and feed the LEDs, and a very slick laser cut cabinet.

Got these pedestrian crossing lights years ago, finally getting around to making something out of it. Adding LED panels and a Raspberry Pi Pico W with a web app and physical button to control them. Something for the kids to play with.
