@therealcarlin very chinese of you

I'll let my kids have a tablet or phone as young as they want. Up to them. But, they have to make it themselves.

@i2cjak you just lack the 中國人 mindset, 白妖怪

most performative slave award

@SoraUnchained @anarch97 and you left with your ass and mouth turned out

@anarch97 I got into Stanford by pretending to be DEI (anyone can visually see I’m not) The best one available to us was to say we were LGBT Very hard to disprove, immense upside, and you can just claim you’re bi (lmao) I got in as a straight guy

lol

@Insigolon @_Stocko_ yes!

@_Stocko_ So robots should have skin?

this is how many sensors robots need to have

@lithos_graphein i hope this doesn't affect my chemical supply :<

Brewer Science will acquire Heraeus Epurio, which manufactures raw materials for lithogrpahy in Dayton, Ohio. - Photoacid generators - Photo-initiators - Monomers - Crosslinkers - Trace metals purification

@i2cjak giving brain

what's it called when you can't unclench your jaw

@blind_via not forgotten! flash sintering tools for printed electronics still use these :)

Tall and proud. Old school tech that is now forgotten. These old giant caps would shot the F out of you if you were not careful with them.

@_Stocko_ inches should only be used to measure cock size, nothing else

the chinese are all in on the millimeter. the only thing holding back total millimeter domination is the 0.1" spacing on breadboards

I can’t tell you how sad it makes me feel when someone reduces all of my work to an “Aliexpress case”. When you call me a larper and an embarrassment, you’re not insulting a marketing department or some huge corporation. You’re directly insulting me. I’ve always been transparent about the parts I use, how much they cost, and the fact that some of them come from China. Not Aliexpress, but factories that manufacture watch components. I don’t think that should invalidate every prototype, every sketch, every failed attempt, every jig, and all of the work that goes into the things I do beyond the case itself. I’m a one-man band, just a guy doing his best to achieve his dream of making watches. All of my dials are cut on my own laser machine, hand-drilled, hand-sanded, and hand-painted under a microscope. Sometimes it takes days to finish a single dial, and I am incredibly lucky to have found people who appreciate that work. If everything were as simple as you say, everybody would be doing it. Creating a worthwhile physical product is difficult. It takes years of learning, thousands of mistakes, and a level of commitment that most people never see. To top it all off, you mention how you want to do the same, and how you: “just need a garage, a lathe, and a pad printing machine so I can finally free myself from the shackles of other people’s taste in this matter” I’m 24, still immature in many ways, but old enough to understand how difficult it is to create something with your own hands. Whether I like a person’s work or not, I know how much effort, sacrifice, and vulnerability goes into putting it out into the world. It took everything in me to get where I am today. Years of saving to afford more than €20,000 worth of equipment, years of tinkering, starting from absolutely nothing, not to mention all the sleepless nights and stress that went into creating something like this. You don’t have to like it, but you don’t need to belittle it either. It’s very hard to gain confidence by tearing down the work of other people, but getting shit done is something else entirely. (I’ll use this day to post more about the costs, how much I make exactly per watch, how much money I made so far, and how I’m still about 11000€ short to just pay off my gear, let alone all the time sunk into this black hole of a hobby, it’s far from glamorous, so I’m excited to share)

@willreil get his ass, king

a CHUD will tell you to use a $3 nRF54L15 "because it's better and has bluetooth" but a CHAD would use a $0.50 ATTiny412 that does the job just as well, assemble the whole board for less than $3, and pocket the rest. low cost profitable hardware 101 (thank you for the advice)

@Xaraphim finally, a hairclaw for the classic situation where i place my wife on a 40 kHz shaker table

my wife is going to be so spoiled man it’s so over for me

@Control_wiz hearing tactile sensors is like music to my ears :)

It's well known that you need three fingers for stable manipulation. With two fingers you are limited to pick and place tasks. The missing part has been tactile sensing. There are decent ones but they are very expensive. The gap is robust multi finger manipulation with cheap force sensors.

@1p_semicon has this been published in a journal?

九州大学発の新技術。 人の皮膚のように広い面で温度や触覚を感じる「電子皮膚」に用いられる温度センサアレイ。従来はアナログ回路とアナログ-デジタル変換器（AD 変換器）が必要だったが、アナログ変換せずに直接デジタル信号として読み出す新方式に基づくセンサアレイシステムを世界初開発。 これにより、極めて低消費エネルギーかつ⾼速な読み出しを実現した。 kyushu-u.ac.jp/f/66280/26_061…

@gabednconfused how different is this from the voltera machines? you can direct-ink-write batteries with those as well.

The problem with designing and building your own machines There’s no one to call and yell at when they breakdown

@al_bert_1901 Link it

Yeah we still have a problem. Turns out SLA straight up poisons the silicone. Doesn't cure AT ALL. Next we try painting the molds with lacquer, I guess.

@therealcarlin eh, you could, i just like inhibit X since 2 brush coats work with no issues.

@al_bert_1901 Was thinking about painting them with a lacquer based primer first.

It didn't work. The rubber left over in the cup cured within a couple hours. The feet didn't even cure in ~20hrs. I wiped the molds down with WD-40 as a release agent so maybe that's why? It's a mystery.

@IanPritchard i like the concept of hydrogels, but how are you supposed to keep them at a constant "wetness" to prevent drift? maybe i should first ask how you're going to use these as actuators.

First hydrogel test was a success! Next batch I will increase the electrolyte contents and hopefully end up with some actuators, or passive sensors at the very least.
