getting another set done

Active full‑to‑half‑duplex UART conversion (2× NAND + OR). Falstad: is.gd/eW6BNm

S7RVO C.T.R.L | Silkscreen ready. This style is user-oriented. Only the necessary information for connecting. Other prefixes etc.. can be found on the document layer, which is not drawn. #Firmware #HardwareHacking #IoT #Innovation #EmbeddedSystems #LowPowerDesign #Falstad

Power path is simple: Battery → PTC fuse → P‑MOSFET → system B+ The MOSFET gate is tied directly to ground for consistent behavior. Bulk capacitance sits on the system side of the MOSFET, and each IC has its own ceramic decoupling.

@ToddMory @mikerankin @IObrizio Yep. TPSM81033.

@webronen @mikerankin @IObrizio Looks like a Tetris nightmare.

What nightmares are made of…

Testing interceptors🤠

Do you have need of a microswitch with a custom lever? Here is a 3d printed design that uses a tact switch. github.com/ruenahcmohr/Ru…

@RueNahcMohr I like this. "Best part is no part."

Build external data files for the Arduboy FX games you are building: bateske.github.io/Arduboy-Webtoo…

yay it works! This is the magnetically-returned, optical sensed collision whisker for this weeks robot. The chip is a 74ls04 which acts as pullup and threshold.

BOOM! A stencil I got quoted $20 for now costs $0.01 to make Nobody believed in the 3d printed stencil but it worked perfectly! You guys are all crushed under the boot of big stencil. While I’m liberating the people. Start 3D printing your own stencils, it works!

@willreil @eevblog Wow. Have to try. Thanks. I have used fibre laser for stencil and PCB manufacturing.

@zackslab HW without FW/SW, is Zombie. FW/SW without HW is imagination.

hardware is so unforgiving. software is child's play. literally a playground of unicorns and rainbows.

I really enjoyed this ESC design. Based on TI DRV8850. Brushed.

NANOHOLD R.E.G.A | Voltage monitor Voltage monitoring is handled by a 0.28 inch 3 segment display. Also ON-OFF switch and a monitoring button. The part is easy to print and install, as you can press the ends together with your thumbs and release. Advantages of PLA printing.
