Assembled a third artificial muscle today! Growing my collection.
Bet you’ve never seen an actuator that looks like this! Just assembled the actuator and ready to run some tests.
Flex PCB order finally arrived! This is the longest option available at 1400mm. Excited to assemble it and test it out!
Did some laser micro-machining to prototype a new Flex PCB design for the robotic muscle project. Being able to iterate daily rather than every week will be huge.
Pyralux samples acquired from DuPont. Soon I will be making my own Flex PCB.
New tests for a new year (!) Wish me luck as I upgrade my power supply, to avoid charge retention. Still, good progress. Also, there’s a fancy machine at Waterloo that I want to try out. Can prototype flex pcbs in a few hours, don’t have to wait 7 days for china.
Same prototype as the video yesterday, but now it’s hanging! I’m still facing an issue with arcing (since the copper is exposed). Next design is fully insulated, so should be able to run 3-4x higher voltage. In theory should result 9-16x the strength. But that’s just a theory..

The Frida Kahlo Quick-Build Project is up for approval next week, thanks in part to the people who signed the petition supporting it! If you haven’t signed the petition, sign it now at actionnetwork.org/letters/fridak… — it only takes a few taps and less than a minute and makes an impact!
this right here is the electoral impact of the housing shortage whenever fake “progressives” in San Francisco or Boston push NIMBY policies, they are literally helping the Trump campaign
We need SF to work. Many thanks to @moritzKBE and Neighbors SF for fighting for an SF that is truly amazing fixsfgovernment.com/vision
San Francisco is a weak mayor town - structurally the Mayor has been completely hamstrung by decades of bad policy led by Aaron Peskin, the head NIMBY doom looper himself. This policy must end.
San Francisco has 130 commissions and more than 1,200 commissioners! And many receive full health care insurance from the city. No wonder no one is accountable for getting things done right. Even Los Angeles, many times the population of our city, has only 49 commissions.
Of the hundreds of local governmental meetings I’ve attended, tonight’s Half Moon Bay Planning Commission debate over a 100% affordable housing project for senior farmworkers may be the most infuriating one I’ve ever been to. And that’s *really* saying something.
@EmilybyNight higher end: - cotogna - bar sprezzatura - spruce - nopa - flour & water middle: - che fico - hog island oyster co (ferry bldg) - good good culture club low-but-fun: - radhaus - zeitgeist (they have food, it counts)
This is how it's done. Why do new buildings in SF look like hot garbage? Oh right, @sfplanning's absurd "design guidelines" that actually mandate some of the worst new architecture on the literal planet.
this guy’s been in and around #SF City Hall for more than 20 years, he must have gotten inspired

Damn that's wild
Ok but YIMBYism is obviously right wing lol
By that logic, Cupertino's rental market must be very affordable given how fiercely the city has fought against developers wanting to build tall, dense housing there. Now to take a sip of this coffee and look at what rents are going for.
@arram @HousingSpock The "build up and everywhere" people are advocating for Developers to create a massive and expensive rental market in CA. Places like Oakland, Austin who have seen dips in rents - those dips are due to people leaving/lack of demand. Developers now pack up and leave.
This kind of "permission slip culture" is exactly why we need permitting reform at every level of government
The first gear made on our 4-axis wire EDM machine! 30 teeth at a 0.5 metric module with a 14.5 degree angle. Precision and achievable complexity will only increase as we improve our craft.
An interesting response we've been getting: “This video is cruel. I can’t leave the city. My job, friends, and family are here!” Yes. That's why we shouldn't block housing in cities and price people out.
If You Hate Density, Maybe Don’t Live in A City: youtu.be/LQCvIRfRgX0
Good news of the day: The federal government is shifting away from credentialism and toward skills-based hiring.
Ever wanted to machine your own custom brushless motors and gear boxes? Desktop wire EDM is going unlock so many possibilities on the tech tree.
SF is the most childless major city in the nation due in large part to Aaron’s unwillingness to support more housing. We have a housing shortage crisis, which leads to displacement & exorbitant housing costs. Two decades of Aaron’s NIMBYism at work. sfchronicle.com/sf/article/few…
I am proud to have protected Baby Prop C funding from being diverted in last year's budget. Quality childcare is a lifeline for working families + our early childhood care workers are true heroes who deserve wages that allow them to thrive for the incredible service they provide.
It’s easier to get a gun than a Below Market Rate (BMR) apartment in SF. Hundreds of BMRs perfect for families and first responders sit empty despite over 1,000 applications because of an absurd City Hall process. It’s time for a City Hall that works for us and not against us.
4 months ago, 14 builders chose to uproot their lives and put all their savings on the line to move to SF and build at The Residency for those of you who want to see their insane progress over the last 4 months, this is what our demo day was for 🧵👇
