でも、そんな北海道でも、莫大な埋蔵量を誇る石炭や復活可能な炭鉱に注目が集まれば、あの明治大正の時代の、破竹の勢いだった北海道が帰ってくるはずなんです!石炭さえ、石炭さえあれば、北海道の鉄道路線はまた元通りに、いやそれ以上に伸びるはずなんです…!!!おい何をする俺は正気だ
日報さん🍎@nippou_

海外含めたくさんリプライもらってるのにお返事できてなくてごめんね…北海道の鉄道がまた廃線になって落ち込んでいるんだ…鉄道がなくなったところからなんとなく寂しい町になっていくから、まるで鉄道は土地の血管のようだなって思っているんだ…また北海道に血の通わない部分が増えてしまった…

This is why all our bus drivers are all fat. Physics respecters. All the bad kids congregate in the back so you can’t have a skinny driver and maintain aerodynamic stability. Math.

アメリカのスクールバスと言えば、私の娘が乗りこむ車両を見るたびに「後輪の後ろ長すぎない?後方の座席にアメリカ人が集中して乗ったら、これウィリーしてしまうのでは…?」と少し不安になっていた

ElectronicsNotes by Ian Poole
The Swiss Army Knife of Power Supplies: Why the LM317 Still Rules In a world of complex power management ICs, sometimes the classic solutions are still the best. The LM317 adjustable voltage regulator has been a staple on engineer workbenches for decades - and for good reason. Whether you're building a variable lab supply, a constant current source for LEDs, or local on-card regulation, this 3-terminal wonder is as versatile as it is reliable. Based on information on my website , here is why the LM317 should still be in your component drawer: Key Features • Wide Output Range: Adjusts from 1.2V all the way up to 37V. • High Current Capability: Capable of delivering over 1.5A with proper heatsinking. • Floating Regulator: Because it doesn't have a dedicated ground pin, it can be used in high-voltage applications as long as the input-to-output differential is maintained. • Robust Protection: Built-in current limiting and thermal overload protection make it incredibly "forgiving" during the prototyping phase. Pro-Tips for a Stable Circuit To get the best performance out of your LM317 design, keep these practical tips in mind: 1. Capacitors are NOT optional: Use a 0.1µF ceramic on the input to handle line impedance and a 1µF tantalum on the output to ensure transient stability. 2. The "Protection Diode" Trick: If you’re using large output capacitors (over 25µF), add a protection diode from output to input. This prevents the capacitor from discharging back through the IC if the input is shorted. 3. Layout Matters: Keep your programming resistors as close to the IC terminals as possible to minimize voltage drops that can degrade regulation. 4. Heatsink Connection: Remember that on the TO-220 package, the metal tab is internally connected to the Output pin, not ground! Always use an insulator kit if mounting to a common chassis. The LM317 is a testament to the idea that good analog design is timeless. It’s cheap, widely available, and virtually impossible to make obsolete. For more information check out my website - link in the comments. Are you still using the LM317 in your modern designs, or have you fully switched to LDOs and Switchers? Let’s talk shop in the comments! 👇 #ElectronicsEngineering #AnalogDesign #PowerSupply #LM317 #ElectricalEngineering #MakerMovement #CircuitDesign #electronicsnotes
