@boxcardavid axial flux any?? Would love to start seeing more super flat axial flux.

A motor this small in NEMA packaging is like a boy in his dad’s suit

@lvjin1993 I wish they had these in axial flux style bldc. Would love to take advantages of the manufacturing equipment around that to make some tiny nice motors.

这款超薄步进电机确实把空间压缩到了极致，力矩密度高、动态响应快，小机身大能量，真是蚂蚁扛鼎！

@ZombieHedgehog_ @emberprototypes looks like it was enough of a problem that they had to add dedicated Nozzle Calibration.

This is going to succeed because of this one part: Automatic Nozzle Calibration. Looking forward to seeing this in peoples hands, and hopefully get my hands on one soon😁

@observie @saleae Very nice capture. I really like this scope. I love how they are using the USB C wires for digital probing.

This is my scope. It's a 12-bit, 200 MHz, 1.6 GS/s no-knobs scope and logic analyzer combined, specifically designed for embedded systems development. I'm a long-time user of @saleae's logic products. They're not cheap, but I've always felt they give me an edge on whatever I'm called to debug. This one is called the "Logic MSO" and it takes debugging to the next level. I still have my analog scope around, but just for sentimental reasons: I haven't used it once since I got this bad boy. Probably the biggest advantage of the Logic MSO is its ability to record a long session and then just scroll, zoom, and annotate. No more missing rare events and you get to see the before and after. It was instrumental in debugging the BMS issues below: being able to record a night-long session was invaluable. The fact that their software is super intuitive and runs on Linux helps too.

@Gundrium @Cpt_TAKAHASHI Love this setup. I have the 556 MDR with 6x magnifier and eotech I want to also get the .308 setup too.

@Cpt_TAKAHASHI Have some more! Here my MDR, in .308, with the longer barrel and the Medium Power Variable Optic in black. And my brothers MDR with the Eotec/ Magnifier setup chambered in .223 with the shorter barrel in tan!

写真を見せてくれと言ったら、想像の10倍のgun photoが届いて困惑しているよ。

@boxcardavid Lol I have two! Wife thought it was crazy at first. Now she wants me to get an embroidery machine.

“Do you own a sewing machine?” is my favorite interview question for engineers. “Is it a serger?” is the follow up that really clinches it.

@blind_via If you were making a flight controller or something similar you would need to make much more significant gaps that may no longer be worth dealing with. I was limited in my ability to connect ground to the chassis so spark gaps worked well.

@blind_via Pick a good value and test. Closest point was 8 farthest point was 10 mils with. I used a round trach surrounded by ground plane. The product is not going to be used beyond 10k feet. I won't be doing pulling a vacuum to test but that is outside the scope if the product.

These features on the pcb look like little bugs faces. I think this is for shorting across on purpose like a jumper, but for more current.

@blind_via This was used on the chassis to device ground. The current version is designed around 1.5kV at sea level. Anything smaller should not be able to jump to sensitive components anything larger should only use this spark gap path. All other interfaces have dedicated protection.

@MarcosLima260 how do you account for different environments it will exist in? arc gap varies a lot based on altitude and moisture environments

@MatthewTavares @dddpworld I had seen these before. They are very cool. I wonder if you could do it with a single gear and deflect the whole gear. Basically like a wave washer.

@MarcosLima260 @dddpworld It would need two gears where the teeth smoosh together for that. See sdp/si: shop.sdp-si.com/products/gears…

This might be my most requested print. Any guess what its for? Can you tell where the inspiration came from? Excited to see how it works...🤞

@i2cjak I find this to also be a bit crazy. Adafruit seems to have a different inductor and others have just replaced it with a LDO. I really think it is some EMI thing that they are not explaining clearly.

POV you are handholding the most retarded switching regulator design of all time

@shapoco The answer is always more RGB. Add the data pin for an ARGB LED.

拡張端子の余った 1 ピンに繋ぐと良さそうな信号あるかな

@boxcardavid Hey where did you get our motor? /s

I should sell keychains

@okatyannel These are really neat. I had been wanting to make these for some time but never got around to it. Would have never been able to it the super low price anyway.

アリエクでMicro-USBからType-Cにポン付で交換できる端子を買いましたがけっこう良かったです。 これで個人的に一番大嫌いなUSBの中のmicroから離脱できますw micro-USBが好きな方はいますか？

@boxcardavid I have noticed if the company has a dedicated site the prices are much closer to what they used to be. Aliexpress is still a bit inflated for me.

Actuator prices seem pretty stable, $175 on taobao for a robstride 04, $280 on their website (links to aliexpress), which is the same as a year ago. What you’ll actually pay after shipping and tariffs will depend on how sneaky you and your shipper like to be

@seveibar Love those little stepper motor drivers. Makes high value projects super fast and accessible

Almost ready for second axis

@denjin_Electric I like it. Very neatly done. Would be interested in seeing how fast it could go.

直下層にベタ張ったけど、本当に意味有るんかなこれ
