I found this project to build NeoPixel bike lights but it's either been abandoned or on a long hiatus.
(I don't want to say it's "dead" because I sometimes go years between project updates.)
Anyway, this is somewhat similar to a few projects I'm working on, and will hopefully complete at some point.

Thinking about powering a small Arduino project with a solar panel and backup battery.
What setups or components have worked well for you? Any pitfalls to avoid?
Gah! So the prototype worked, and all the signals on the new PCB are doing what they're supposed to. But it ain't working.
Must be a timing thing.
Don't mind me. Just grumbling out loud.

Illustrated Dictionary of Electrical and Electronics Engineering. 3ed by Antonio Escobar Molero, 2024
Provides clear definitions and visual illustrations of key terms and concepts in the field of electrical and electronics engineering.
This dictionary covers a wide range of topics, including circuit theory, digital electronics, power systems, telecommunications, and more.
The volume down on Child A's cheap little music player doesn't work anymore, it just squashes inwards. Let's see if I can fix that. The first tricky part is forcing the back open with some spudgers. I always hate this part because I never know what the correct amount of force is to get it open without breaking some snap fitting.

Any recommendations on where to sell finished DIY/maker/small business #electronics ( open #hardware) projects online?
I know there are many platforms out there aimed at this (e.g. #Tindie), but I have no personal experience with any of them.
What are the pros/cons to look for?
Vacuum Technology is used to remove air and gases, making processes more efficient in labs, industries, and electronics.

Still in mint condition & works perfectly well
A neighbor harvested some 18500 LiFePo4 cells from their garden walkway lights, but didn't know what to do with them. They all still have a proper charge (~3.2 V), but I'm not sure how I would recharge them if I wanted to use them in a project.
They can't be charged with a lithium ion charger, so I'm not sure what I should do with these. Anyone have any suggestions for an inexpensive charger I can buy, or a circuit I can assemble on perfboard?

If you're the person who spunked £500 down and properly outbid me on the CSI / CSA Transputer Education Kit on Ebay UK a few weeks ago, I have just one question...
... can I please have a copy of the software disks, and some photos of the ISA card?
If you can't do mastodon, my email address is on https://www.philpem.me.uk/contact .
Boosts appreciated, feel free to share this post with non-Fedi friends!
Kącik buraczanego renowatora amatora prezentuje: kalkulator Elwro 144, rocznik 1983 (więc mój rówieśnik) z niektórymi częściami z roczników '81 i '82.
Robota ogólnie dość łatwa, wystarczyło wyczyścić tony syfu z klawiszy, usunąć zdezintegrowaną gąbkę spod nich i delikatnie przeszlifować ścieżki i pola na płytce stykowej, bo wspomniana gąbka weszła w reakcję z lutem i wżarła się w niego tak, że klawisze nie kontaktowały.
Teraz wszystko działa, ale klawisze są dla odmiany superczułe i trzeba ich dotykać naprawdę delikatnie, żeby nie powielały. Zresztą cały mechanizm klawisza to chamska płaska sprężynka, przewleczona przez dziurę w płytce i trzymająca się tylko własnym oporem - nawet nie wciskana ani nie przykręcona. #retro #elektronika #electronics #prl #elwro #kalkulator

Vietnam to have 50,000 semiconductor engineers : ‘We worry about shortages, not surpluses’
Can anyone please give me advice on finding a reputable seller of Li-ion batteries in the UK?
I want to replace the battery in a solar floodlight. It uses 4 ICR18650 cells at 7.4Vdc, and I'd rather buy a pre-balanced battery pack because I haven't worked with Li-ion before.
