Another huge win for @SeedSigner running* on a microcontroller: we can build touchscreen-native from the start! Text entry is just SO MUCH BETTER on a touchscreen vs the joystick-based entry we currently have. --- *(early & VERY incomplete demo)

if a vandal were to put a low power microcontroller with a metal servo with two blades on the inside housing with a 6V battery & quartz clock that triggers it to cut cat5 daily and weld it back together, it could run for over 2 years, you'd have to take it down to inspect

It's a string rotary encoder. It has an open gate npn output. ~48k pulses over 1200mm of distance. Uses a hall effect sensor on a magnet. It runs on 5 volts, and the output can be direct to my microcontroller, no voltage dividing necessary.

Yes, I didn't play the game. I watched the summarized, 200-hour modded factorio playthrough that requires microcontroller, self-regulating systems knowledge.

Stepper Motors are today's Tasks. Some A4988 stepper Driver a NEMA 17 and an esp32 c3 supermini for the microcontroller.

I keep looking back at the DIY dongles I’ve made before with off the shelf aliexpress microcontroller boards and can’t help but think “I could do better”. Like SURELY there’s no way we’re getting good return loss on the antenna path but like does that really matter for this??

I have started DSi digital video project firmware development on a different microcontroller compared to RP2350. However, conceptually it is the same; MCU will function as update bridge.

Krass ... die Geschwindigkeit der Entwicklung und der Veränderung. Von da aus 75 Jahre ... und was haben Computer u. Microcontroller in allen Bereichen (!) Einzug in unseren Alltag gehalten!

🧲 MagEcoli: What the Paper Actually Describes You've pulled from what sounds like a biorxiv preprint. The core of it is real synthetic biology work: engineering E. colito overexpress ferritin, an iron-storage protein, causing the bacteria to mineralize iron oxide internally. That gives them magnetic properties. They've also engineered surface adhesion proteins so these magnetic bacteria can latch onto specific cell types. With an external magnetic field, you can drag them around — spatial control of a living microbe. That's the paper. It's a proof-of-concept for magnetically steerable engineered bacteria. The applications discussed in the literature are things like targeted drug delivery, tumor microenvironment manipulation, or spatially controlled bioremediation. That's the stated science. 🔬 The Jump to "Nano Robots Hijacking Synaptic Signaling" Now, the bridge you're constructing from that paper to "these are inside humans right now, intercepting action potentials before neurotransmitter release, controlled via Arduino-emulated hardware" — that's a massive inferential leap that the paper itself does not make, support, or even hint at. Let me break down the physics and biology of why this would be extraordinarily difficult: 1. The blood-brain barrier is not a suggestion. Engineered E. coli are micron-scale bacteria. They don't passively cross the BBB. Even if they did, they'd trigger an immediate and catastrophic immune response — sepsis, meningitis, encephalitis. You'd be dead, not subtly mind-controlled. 2. Magnetic manipulation inside a living human is a nightmare. The magnetic forces you can generate externally drop off with the cube of distance. To manipulate individual bacteria deep in brain tissue with any precision, you'd need field gradients that would also yank on every ferromagnetic thing in the body — and fry electronics within range. MRI machines use tesla-level fields and still can't individually steer single cells in real time through brain parenchyma. 3. Action potentials are FAST. An action potential travels down an axon in milliseconds. The idea of a bacterium physically intercepting that signal before neurotransmitter release at the synapse requires the bacterium to be positioned at the exact presynaptic terminal, sense the depolarization wave, and somehow block or alter vesicle fusion — all faster than the signal itself propagates. Bacteria don't have nervous systems. They don't "read" electrical signals. Ferritin mineralization doesn't give them that capability. 4. Arduino emulation? An Arduino is a microcontroller. It cannot emulate a neuron. The computational complexity of even a single synapse involves stochastic vesicle release, multiple receptor subtypes, retrograde signaling, and glial modulation. An Arduino has less processing power than a single ant's brain. The "emulation of hardware through software" framing misunderstands both the hardware and the software…

A man in Hokkaido, Japan never studied agriculture. He never inherited land. He started out as a civil servant. He wanted his farm to run better but could not afford an engineering firm. So he built the tools himself using Claude and an ESP32 microcontroller board. He built remote control of his greenhouse vents from a chat app. He built a bot that checks each greenhouse temperature and opens the vents automatically when it gets too hot. He built satellite crop health data laid over a map of his own fields. He built a database linking his plots, tasks, materials, and sensors. He generated wiring diagrams of his electrical panels from a photo. All of this used to be locked behind machinery and engineers that only large agribusinesses could afford. He bypassed all of it with a laptop and an AI model. He runs a 100 hectare farm. No engineering degree. No team. Just curiosity and the willingness to figure it out. The barrier to building things has never been lower. Follow for more stories like this every day.

The correction tables aren't applied yet, so it doesn't run that close to straight, the microcontroller mount *just* barely works, I might adjust the top clamp on it. the bot "is working" (still) tho.

Do you mean Microcontroller programming?

Just a note - "keep a close watch on the pressure valve" is triple redundancy microcontroller edge devices. Nobody in their mind would trust a human.

A 2-cent dual-core RISC-V motor control microcontroller? cnx-software.com/2026/06/12/… Fortior Technology's FU75xx MCU family pairs a 32-bit RISC-V core and the company’s proprietary 2nd-gen Motor Engine (ME2) core. The RISC-V core is used for parameter configuration and routine processing, while the ME core integrates FOC and CORDIC modules that enable fast calculation of FOC (as quick as 5µs) or square-wave control for sensored/sensorless BLDC/PMSM motors. There appears to be a development board and sample code (C language) to be used with Fortior Tech’s FTM32ForIDE. The FU7512L MCU and other FU75xx parts currently show up to 2 cents per unit (for 444 orders) on JLCPCB, but pricing needs to be confirmed.
