I know engineers who put their numbered lists in ascending order, and they're all cowards.

#engineer #number #order #ascending #descending #NumberedList #numbered #BulletedList #schematic #coward

A small excerpt from a schematic diagram, showing a legend of numbered notes for various things on the drawing. This numbered list is in two columns, but for some reason, the first column's items from top to bottom are numbered 9, 8, 7, and the second column's are 6, 5, 4, 3, 2, 1.

On the off chance someone in my circle knows...

Fender amplifier schematics seem to commonly have a warning attached to some components, saying "DO NOT STUFF". On the schematic for a cheapie Chinesium Fender Frontman 10G that has just decided to fail immediately after the 2-year warranty ended, it's attached to half a dozen capacitors.

I don't know what "DO NOT STUFF" means regarding electronic components in a circuit. I've done some searching (and will do more tomorrow, it's late) but all my results so far are more schematics for other Fender amplifier models - and there are a *lot* of them.

So if anyone knows and could point me to an explanation, I'd be forever grateful.

Incomplete #Schematic of the #Morgue I plan to set my #Chroniclesofdarkness #oneshot. Based on a very large #Reddit post about different kinds of morgues.

The story is partly inspired by The Autopsy of Jane Doe. Note that I said "partially" inspired; players who've seen the movie still won't know everything I have planned.

Incomplete blue print for a fictional morgue.

The front door opens to a reception area, which itself has doors to an office, a viewing room, and a main hallway.

The viewing room has a glass window looking into a sealed viewing room for potentially infectious cadavers.

Behind the office is a staff room and kitchen. Behind the sealed viewing room are a locker room, showers, the post mortem room, and the cold room where bodies are stored.

In the cold room, against the outer wall, are ten columns of four lockers for body storage.

Every time someone designs a #PCB and puts the whole #schematic on one sheet, the Universe ritually sacrifices the cutest #unicorn.

You've been warned, you heathens. Top-level schematic symbols show the logical relationships between your clusterf*ck of parts!

Схемотехника и алгоритмы световых мечей: вызовы и решения

Сага «Звёздные войны» давно стала больше, чем просто серией фильмов. Миллионы людей объединены общей страстью, и для многих из них обладание своим личным световым мечом становится очень важным. Ведь это не только предмет коллекционирования, технологический артефакт или даже спортивный инвентарь, а символ джедайской (или ситхской) философии. На этом интересе вырос целый рынок. Есть компании, которые производят световые мечи целиком. Есть те, кто специализируется только на отдельных компонентах: рукоятях, платах, светодиодных модулях и прочей электронике. Привет, на связи Крэйл из команды умных устройств Яндекса. Но сегодня я расскажу не о Станциях, а о своём необычном хобби. Однажды ко мне обратились производители компонентов с задачей разработать электронику для кастомных световых мечей. Проект оказался ярким во всех смыслах. А в статье я расскажу о том, какие были условия и как я справлялся с поставленными задачами.

Well thanks, Sparkfun. Now I had to spend my morning updating Schemdraw to correct the DB9 vs DE9 name in its circuit element library, and add several other D-sub connectors. 😀

This will be slightly #geeky, and probably only of interest to #electronics hobbyists and #guitar players. I happen to sit in the intersection of that particular #Venn diagram.

When I was a teenager, having only been playing guitar for a few years, I owned a guitar #effects pedal that went on to become legendary - the Boss HM-2 "Heavy Metal" #pedal. Its sound is still ubiquitous in metal.

I don't have it any more. I think I traded it for an analog chorus, which was a seriously expensive pedal back then. Although I have other #distortion effects, I've missed it a lot over the years.

Well, lots of hobbyists build their own effects. And the circuit schematics for many effects, particularly the classics, are available online. So like many others, I decided to build my own HM-2.

This image is the schematic for the #HM2. It's not the most complicated pedal, but it's a league above something like an Ibanez Tube Screamer. As far as active devices go, it's got 6 #opamps and 10 #transistors of various types, along with a bunch of diodes for multiple types and stages of clipping, and the usual jumble of capacitors and resistors. Oh, and four potentiometers.

#EffectPedal #HeavyMetal #pedals #metal #DIY #schematic #circuit #hobby #OperationalAmplifier #TubeScreamer

A circuit schematic diagram for the Boss HM-2 "Heavy Metal" guitar effects pedal. It is fairly complicated as far as distortion pedals go, containing 6 operational amplifiers (opamps), 10 transistors of various types, and 4 potentiometers.

I don't know what goes into "good" alt text for a schematic. Shown here, the input signal enters at top-left and exits at the lower right side of the diagram, as is customary. In addition to the actual signal-processing path, it also includes a power supply section supporting 9V battery or AC adapter and which generates a 4.5V bias voltage in addition to buffering the power supply. There is also the traditional Boss "soft switching" which routes the signal either through the effect, or via a bypass to the output.

Sigh.
