If I don’t buy this MacBook I’ll just cop an Arduino Kit and start Hardware on weekends. But first make I hustle money ASAP

そうか、ArduinoのシリアルからPCに送るんでなくて、シフトレジスタLSIを経由してパラレルーUSB変換基盤を経由して、パラレルデータでArduinoからUSB変換器に送って、USB変換器の8ビットデータのUSB送信を組み合わせれば、データ送信は問題なさそうだなぁ。手持ちで5MHz駆動できるシフトLSIあるし

These Arduino projects are really enjoyable; it's surprising how easily non-tech people get impressed. I believe it's time to explore further in this area, now that I can attempt more complex projects. After that, we'll see what comes next.

Arduinoにもなにか仕事をあげたいところ でも今1番欲しいのは省電力なLLM母艦(スタックチャンの頭が残念なため)

マイコン的存在、自動水やり用に放置してたArduinoと最近スマートホームのハブになれたラズパイに加えて体のないM5 stackと今回お迎えしたスタックチャンの4機になった

小さいバイト数をブロックにして、TCPみたいに再送を頼める位でやり取りしないと無理かなぁ… ArduinoのサンプリングレートとUART送信バッファ(ウィンドウバッファ)の戦いだな。2KB RAMでどこまでやれるのか…という話だねぇw

ふとおもったが、Arduinoで信号モニター辺りなどを作った時にPCにデータ転送をしようとすると、当然U(S)ARTの速度も問題になると思うが、高速になるほどビットエラー率は上がるわけで、何か手あるかなと思って考えてたのだが、パリティON+一定バイト毎に垂直パリティを送れば、修正できんじゃね説が

Arduino IDEが意外と面白い。

Now my files are back (Mostly Yuzusoft save files and some Ruffle flash game save files. These are the most important to me, as these are my records of progress. Other files include Arduino packages so I don't have to download them again) And captured videos were not affected

Pour info je suis basé en Bourgogne 🙂 il y a aussi un peu de route...

Deux salons de 3 jours, deux week end de suite un à Toulouse l autre à Nantes. Je confirme, le bruit, la foule, quand on rentre on est HS! Faut plusieurs jours pour atterrir 😄 n’oubliez pas que le soir on se retrouve entre makers pour manger, boire un coup 😉

SDカード以外の問題となると、フォント自体の設定弄れば解決するはずです。フォント内の.iniファイルにアウト音からハム音の時間がミリ秒で設定できたはずです。 設定は面倒かもですが、やれることは多いです。Arduinoがベースなので、セーバー以外の制御も追加で書き込めるかもしれません

電子工作沼の入口、発掘しました。 Japanino出てきた。 たしか大人の科学かなにかの付録で、これが入ってたのが始まりだった気がする。 ここからArduino、電子工作、渦、ロボット、ペンプロッタへ続いていくと思うと、だいぶ人生を狂わせた赤い基板。

実は、Arduino Nano R4が発売されていたようなのですが、全く気が付かないまま1年が経っていました。 実際のところRaspberry Pi Pico2やESP32マイコンなどのほうが 安い&高性能なのでNano R4の立ち位置がよくわからなくなっている状態です。

Je me disais que c'est une activité qui n'est pas de tout repos. Se lever tôt, préparer le stand, rester au stand, faire la fermeture, ranger le stand, etc. Physiquement, ça doit être fatigant. Je ne critiquais pas et je ne dénigrais pas.

🧲 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…
