#today I am going into uni for supervision (and, I hope, comments on my paper revisions). I didn't get to start the energy system #schematic yesterday, but decided *how* to do it (with an eye to supporting a second use of it), and have started it this morning... The forecast is for 33C today, so I would really rather not be travelling, but I think I must!

#today back on the #research #paper I have updated and extended the abstract - possibly not enough but I will seek my supervisors' opinions. Now on to the home energy system #schematic which is a *big* task and I am not sure even which tools to use...

All the #yeasu #ft101 service manuals online are pretty low resolution.

This really hinders the ability to read the schematics and PCB diagrams.

Given I had an original manual on loan, I decided to scan all the important bits in 600 dpi:

You can now finally see where components go on PCBs

I decided to tidy up my computer since I had a bit of free time.
One email popped up saying that I couldn’t use their desktop app for cloud drive synchronization without a subscription. Not a problem - I’d be more than happy to delete your app.
And while I was looking through the list of apps, my attention stopped on EAGLE from Autodesk - an app for designing schematics and PCB.
This news has probably already become just another unremarkable sentence somewhere on Wikipedia [citation needed], but for me it was a tremendous disappointment that couldn’t be fully conveyed even in a single lengthy novel.

Philips PM3206 oscilloscope service manual with full schematics. Perfect condition. Still in 1989 stamped envelope from its original source in the Netherlands.

Send me carriage cost by PayPal etc and I'll forward it to you from UK. Thanks

Why can't ChatGPT figure out the difference between a crossed line and a junction point in a schematic. Now way to get it to understand. ☹️

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.

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.

It's amazing how I can paste a #schematic into #ChatGPT and have it interpret it. But it's also amazing the nature of the mistakes it sometimes makes.
