Dusting off an old hobby! I forgot how Zen it was to put on headphones and just paint for a few hours. Didn't go exactly to plan, but happy enough with how it turned out 😊

Material science, microfab, microscopy, machining. Mostly :)
The last month of my life: BreakingTTAPs This is a custom transport-triggered, 32 bit processor that will be fabricated by GlobalFoundries on their 180nm process (via of wafer.space) I'll make a video at some point, but some high level details here:
I made a video about this! Laser deposition of aluminum, silver, copper, titanium, invar 36, niobium ITO and (sorta) zirconium. Pretty nifty little technique. Not perfect, has some major disadvantages... but easy and reasonably robust! youtu.be/J0NNO91WyXM

Breaking Taps@breakingtaps.com · last yr.Playing around with a laser thing today and accidentally found a good set of parameters for transferring aluminum onto glass. Neat!
Had a long flight and finally got around to fully reading @benjaminreinhardt.com 's essay on DARPA, why it works, where it struggles, and how it might be replicated: blog.benjaminreinhardt.com/wddw Very thought provoking read. Been on my todo for ages, should have read sooner!

Oh hai there, look what I found in the bin of childhood stuff my parents dropped off 👀
Shoutout to bad decisions that past BreakingTaps let future BreakingTaps sort out 😑
Getting ready for my $5.50/hr reindustrialization sewing job at the textile factory. 👊🇺🇸🔥
Lol futures for S&P, NASDAQ, Dow etc are like a vertical cliff. So much winning! jfc
The annual urge to build a modern letterpress has sidled into my brain yet again. 🙃 Hand-fed platen press, ballscrew/linear rails/servos to actuate press and inking rollers. Resin print the plate. Load cells to automatically tune the printing pressure, etc etc.
Large area deposition ends up being quite easy, but does require a spacer between metal and glass which limits ability to pattern. Ag is great, Cu is tricky (oxidizes easily). Ti, Nb and Invar 36 seem good. Can make TiO2 easily too. Zr seems to oxidize immediately

Shameless shilling: I'm selling some esoteric equipment! Want a 200 femtosecond IR laser, or a 532nm picosecond laser? How about a linear motor stage with 10nm resolution? Or an XYZ wafer stage with 250nm steps? I gotchu: www.ebay.com/sch/i.html?_...
Designing hardware for space is, unsurprisingly, hard! Join me for 35 minutes of discussion about all the considerations that go into designing and manufacturing a tiny little hinge.

Have some external deadlines popping up in my life so need to stop messing around and finish a video or two. First up: space hinges! Yell at me if you see me on social media before a video is posted plz k thx 🙏
Academic paper pet peeves: - "Facile" 🤬 - "Wearable" or "Flexible" as justification for importance - "Green process" because it uses a slightly less-bad solvent
SIGH. Aligning optical assembly today and huh weird, red beam isn't passing the UV dichroic beamsplitter. Oh right that's because it's actually a UV bandpass filter 🤦
Waiting on a few components, but the rough layout is starting to look like a thing Litho v3 soon, hopefully? 🥺
I'll be at OpenSauce again this year! Had an absolute blast last year, and for some reason they decided to let me come back 😊 Looking forward to seeing all the cool exhibits and chatting with attendees!
