Solar Reflector

Solar Reflector

Whipped together a quick solar reflector. My goal was to get it to boil some water, ended up cooking lunch with it.

The full story is up on my blog (link in bio). It includes build details (3d files, BOM, code, etc.), a superfluous explanation of what The Voice is, and even a video with its original aspect ratio still intact!

Built a fume extraction setup for my resin printer Built a fume extraction setup for my resin printer. Initially, the fumes were barely noticeable if I kept a window cracked while printing. But I recently tried a new resin (@sirayatech Blu 🤩) and man it gassed me out just sitting in the vat with the printer off. There’s plenty of tweaks to be made, but this should be enough to test the concept. It’d be great if I could keep printing indoors and still join my work calls without feeling like I just got off a 3-day paint huffing bender.

Had an awesome time taking a helicopter lesson las Had an awesome time taking a helicopter lesson last week!  Wasn’t sure going into it if I’d really get to do any piloting given how complex the controls seemed, but was  thrilled by how much I actually got to do.  Having never flown in a helicopter before, I was amazed how nimble and smooth it was (when the real pilot was flying, that is 😅). 

Some fun facts I learned: you can land a helicopter even with no engine power 🤯, but if you let the rotor RPM dip below a critical level, you’ll go into an unrecoverable stall and fall out of the sky 💀. 

Shoutout to the super knowledgeable and enthusiastic Jonathan at @mnhelicopters for making it such a great experience!
Molasses in January would give my writing speed a Molasses in January would give my writing speed a run for its money.  Nevertheless, I finally finished up a blog post about decoding and spoofing a wireless temperature sensor using software defined radio and a neat open source tool called Universal Radio Hacker. Check out the link in my bio if you into that sort of thing.

The prototype circuit boards I designed for the ne The prototype circuit boards I designed for the next incarnation of my Tirsty Tannenbaum Christmas Tree Monitor showed up today from @oshpark !  I’m curious to see if it can outperform my scrap aluminum + food saver bag setup from last year.  TBH I’m so proud of myself for that little logo that I won’t even be mad if it’s a total flop 😎🎄

I wasn’t sure what kind of signal conditioning would work best with this kind of thing, so I decided to just leave the electronics off and make a bare capacitive probe to start experimenting with. The electrodes are made up of wide traces in the top copper layer, which are of insulated from the water by the solder mask. The sensor is broken out into two sections vertically. The bottom 1 cm forms a reference capacitor and the remaining section forms the sensing capacitor.  The ratio of capacitances between the two should be directly proportional to the water level, once the reference is fully submerged.

Trying to up my game with my WiFi Christmas tree w Trying to up my game with my WiFi Christmas tree water level sensing rig this year 🎄. Designed a custom printed circuit board (PCB) that will replace the “FoodSaver bag and aluminum scraps” capacitive liquid level probe. Hope @oshpark can fab it in time. …and that it actually works 😅.
