I like motors and actuators, America needs to make billions @westmagco
- Western engineers often have no exposure to the cheap CNC work being done in China. Your milling costs are China's margin
Replying to @boxcardavidStamping. Laser cut fan profile, then bent to shape. Either than or die cast/injection mold. I wouldn't be surprised if it was plastic with a shiny coating. Even at 1000 quantity, even in China, you're looking 100/part for cnc. - Disney published a paper about computational design of mechanical characters in 2013, super cool

00:15it’s so over they automated italians. - Dyson knockoff turbine motor fans are dirt cheap on Aliexpress and going into fun stuff like these handheld fans that move a lot of air. 200 watts 200 grams CNC impeller $5, crazy.

- I got on Aliexpress to check the latest CNC fan prices but I had to close the app right away

00:00 - CNC and laser cut aluminum is cheap enough that you can always do one-off prototype heat sinks like this. It looks amazing too.
BLDCドライバ作った。これから頑張って回す。 - Self-delivering bikes are worth a revisit at some point
00:00 - Ebike and escooter motors make great actuators
00:00 - I’ve followed this dude on YouTube for years, I don’t know anything about him except he makes super aesthetic motor and bot videos

00:39 - I encourage everyone to drop a .step file into cnc.jlcpcb.com. No sign up, no drawings, you'll get pricing immediately. $40 shipped, MOQ 1
Replying to @boxcardavidThis is one side of the coin. Let me tell you as a person who has tried it. First of all, they want to produce only large series. If you are in the market for one to ten pieces, forget about it. Second, if your piece has very precise tolerances and needs special equipment for - Pro tip, if you drop a bolt kit on the ground explosively just throw it all away and get a new one. Don’t live out a physical sorting algo with your precious engineering hours.
- Jony Ives’ studio at Apple didn’t just have CNC machines for prototyping, they were identical to the machines in the factories in Shenzhen. His team designed the parts, the fixtures, and the manufacturing process.
Btw if you’re looking to get into industrial design I wouldn’t start anywhere else except Jony Ive’s biography. He’s the designer behind the iMac, ios7, iPod, iPhone, AirPods, Watch, etc, but the book goes into what about his skills allowed him to get that position, and the
