[Перевод] RESISTORS: как подростки из 1960-х работали с компьютерами до эпохи ПК

В конце апреля 1968 года компьютерная конференция в Атлантик-Сити едва не сорвалась из-за забастовки телефонисток: терминалы крупных компаний стояли мёртвые. И вот посреди этой неразберихи в центре внимания оказалась небольшая группа подростков из окрестностей Принстона. Они раздобыли акустический модем, подсоединили его к ближайшему таксофону — и вышли на связь с удалённой мини-ЭВМ. Отраслевая газета Computerworld вывела их на первую полосу с заголовком в духе «Школьники украли шоу у профессионалов». Эти ребята называли себя RESISTORS — придуманная задним числом расшифровка аббревиатуры: «Radically Emphatic Students Interested in Science, Technology, Or Research Studies» — то есть «Радикально увлечённые ученики, интересующиеся наукой, техникой и исследованиями».

I can safely say that it's been a while since #DigiKey sold #resistors in pre-packed bags of 5 with included card labels. As their own brand. Made in Taiwan.

Or called themselves "Digi-Key Corporation".

More seriously, I found a bag of #components left over from my senior year of school, when we did our big final project. Mine was a computer-controlled slot machine. Components were seriously expensive then; I organized a group buy with 4 or 5 of my classmates through "Digi-Key", partly because they were cheaper than the local suppliers (see previous story about the "Two Weeks Ten Bucks" guys), but also because we could get quantity price breaks on stuff that was common between our #projects, like the 1 kΩ resistors. IIRC, the resistors cost about $0.30 each in the 5-packs, but the bag of 200 was *way* cheaper - about half that, I think.

These were ordered in 1997, so almost 30 years ago. In addition to #vintage resistors, I found ZTX549 PNP #transistors (still in stock at DigiKey today!), MJE2955T #PNP transistors (also still in stock!), 3 different brands of 741 #opamps, including made-in-Japan and made-in-Malaysia #NEC, TI ones from Taiwan and the Philippines, as well as #TI TL081CP and LM318P from Taiwan. Also a bunch of 74-series logic #chips and some weirder stuff, like a #Motorola MC14412, which is essentially a 0-600 bps (~baud) modem-in-a-chip.

So if you need some vintage components, hit me up 😉

I'm looking for #opinions from #electronics #hobbyists or professionals.

When I'm using a #solderless #breadboard to prototype circuits, resistors can be frustrating. If you just keep re-using the same well-worn ones that look like a pretzel, you have to leave the leads long for the unknown next place you want to use them, and you can accidentally short something else against the leads.

Over the years I've frequently thought "Someone must make #jumper wires with inline resistors so they're easy to reuse", but I've never seen them for sale. [1]

So I made a bunch. And wow, it's labour-intensive to make them well. That explains why no-one's selling them.

Would other people be interested in buying and using these? Anyone can make them, but a lot of people would rather use their limited #hobby time to make their projects, not make things they need to make their #projects.

I've reduced the amount of time to make them and will keep trying, but I would have to charge at least US $30 for a pack of ten. There are ways to reduce it further, but they require a significant investment in equipment, so I'd have to be selling quite a few.

I make them with good materials - silicone 26AWG #wire for flexibility, name-brand 1% metal film #resistors, total length 24cm.

Would anyone want these?

[1] Closest thing I've found is https://www.dfrobot.com/product-1438.html but they're rigid so you need to use an additional wire anyway if you're not connecting exactly that distance through clear space.

Finished #soldering. What I learned so far: l should clean between soldering #SMD components and #throughhole ones. I should leave enough space between the SMD components. I also dislike 0806 #resistors, better get some in 1206 size. The #capacitors were okay.
I tried it out with a square and a triangle wave as two inputs, connected through #potentiometers on a mini #breadboard and looked at the #oscilloscope

#Organizing and #Protest #resources. Intro 3/3.

Additional sorts of organizations that may be of use for #resistors include human rights organizations, political parties, some religious organizations ( eg Bishop #Budde 's #EpiscopalChurch https://www.episcopalchurch.org/way-of-love/ ), unions and more. Resources include guides like this one or the "Protester's Link Compilation" (https://linktr.ee/peacefulprotest) as well as specific advice.

As they get catalogued, theyll be added to the pinned post: https://mastodon.social/@VoxOhm/113947435965408477

#finished #soldering the #perfboard. The #TL074 and the #LM13700 are already inserted, too. Will give it a try tomorrow, now is too late.
I forgot to order 120kΩ #resistors, so I used 100kΩ ones and added 20kΩ #SMD resistors on the back side.
While planning the #PCB layout, I sometimes used diagonal traces. At three places they went directly through neighboring solder joints, so I had to insulate them. In future, I'll use them less often.

We were poor students. Electronics were still quite #expensive (it's a long time ago ... mumblety-five years or more...). I needed #transistors and 10W power #resistors and 1/4W resistors and #diodes and I don't know what else, and most of them besides the 1/4W resistors were a dollar or more each. Even plain resistors were 20 or 30 cents.

By splitting the shipping charge between us and buying common parts so we got the #price #break at 10, or 100, or whatever units, we saved a bunch.
