Back on the air! Now to try transmit. Old power supply #capacitor was failing... lucky I had an extra new one!

@ieure @ifixcoinops

This is all fantastic info, thank you both.

When it comes to basic restoration like re-capping, is it straightforward? Specifically, did they tend to use standard, marked components so it's easy to see what they should be replaced with? Schematics/service manuals findable on the 'net?

More modern electronics with sanded-off, lasered-off, or never-marked-in-the-first-place components is annoying to try to do this with.

Why I reinstalled Mastodon?
I actually need a scratchpad or shall I say, a slightly better than a CRUD message API, note keeper.

What am I keeping?

Since I've been bashing my braincells against #Dart and #Flutter for the last few days...

JSON to pretty much anything

Dart is really retarded when it comes to JSON serialization.

I wish I could just write mobile apps in Go...
or if there WAS A USABLE #KEYCLOAK ADAPTER FOR #CORDOVA / #CAPACITOR.
Instead there's...

Why can't there be one solution that fits all, without having to jump languages and even packages?

Why is mobile such a fenced off world?

{BREAKING NEWS] World Exclusive: Nichelle Nichols (Lieutenant Uhura) and Leonard Nimoy (Spock) - Star Trek (1967) - changing the AMIGA expansion board capacitors with a soldering iron from the future!

#amiga #commodore #cbm #caps #capacitor #startrek #Spock #uhura #retrocomputer

Current experiment: Using a super-capacitor instead of a LiPo battery to power a #LoraWan sensor node.

The #capacitor holds enough charge to power the microcontroller and sensors for 9h after it gets dark (dynamic transmission interval, 10 minutes max).

Controller used is a Heltec Cubecell AB01(v2).

Code is on Github: https://github.com/wtremmel/heltec-cubecell-lora-sensors

These are the insides of a #Philips DVP630 #DVD player. It has been broken for a few years and was given to me.

There are 4 boards inside. From right to left is the power supply (directly from mains), the main board, and a board for #SCART output. On the bottom is the front panel board which has standby/play/pause/etc. buttons and a small display. On the left there's the DVD reader (with a long jammed DVD in it).

The player did not turn on. After some research I found that on this model this may happen due to a bad #capacitor, C316 on the power supply board. You can see it slightly bulging in the picture (not the best angle to see it, sorry).

This is a 1000 μF 10 V capacitor. I did not have 1000 μF capacitors so I didn't try to repair this for a long time.

Recently I wanted to watch some DVD and so I thought "okay, let's see if I can repair the DVD player". So the other day I went to buy some 1000 μF 16 V capacitors. 16 V instead of 10 because I suppose this capacitor normally fails because a slightly larger voltage one should have been used in the design. Hopefully a slight larger one will last longer.

The repair was very easy, just disconnected the board, desoldered the bad capacitor, soldered the new one. Parts cost was 15 cents.

I also found the #schematic for the boards online. Capacitor C316 is related with the circuitry that ends up producing a 5 V source. I measured this after I replaced the capacitor and reassembled the player and sure enough 5 V were there (shame I didn't measure this point prior to the repair, but I didn't want to get shocked due to a large charged capacitor in the supply).

The moment of truth followed, tried to power the player on and it worked!! DVD spins, display says "loading", then "play" then starts counting seconds.

Now to test the player. The outdoors are analog. To my dismay my TV only has HDMI 🤦‍♂️

Tested on my parents TV which has AV input. Used a SCART to AV cable. No image detected 🙁 what a disappointment. You win some, you lose some.

A few days followed. I had the ideia that maybe the SCART board is bad, that maybe using the AV output directly would work. I didn't have an AV to AV cable at hand though. Then the other day my girlfriend found one.

Yesterday I tested the player's AV output. And it worked! The player works baby!!

TL; DR: I managed to repair an old DVD player. SCART does not work but AV does. May investigate this in the future.

So, in just over an hour I was able to port over the #react components from my EV Cost proof-of-concept next app into #ionic and kick out builds for Android and iOS via #capacitor

Everything’s working as expected including Local Storage, so… uhhh, i guess now i go back and actually design this thing out, do some refactoring, and publish it to app stores? Seems too easy…

Yeah, I’m not doing that 😅. It’s too much work plus there’s some amazing apps coming out — but i did get around to learning more about the #capacitor and #ionic ecosystems and they seem like a really good fit with what I already know. Maybe I’ll build my EV Tools app which is mostly math with a few API calls 🤷🏻‍♂️

Back when people were having furnace problems others were bringing up talk of #motors and and they're starting #capacitors going bad Etc so maybe this is an inexpensive one you could stock up on if you need it.

Do #Neopixel strips require me to add a #resistor or #capacitor? #microelectronics #rp2040

Hi folks, so I've decided to use Mastodon - will no longer be actively using my Twitter accounts in a week or so as I'm not enjoying the mess that the new "leadership" is making of it.

Building a distortion pedal and I'm missing one capacitor! Argh! So frustrating.

Does anyone here have a . 47uf (or 470nf) film capacitor with 5mm lead spacing they can send me? I'd rather not pay more in shipping than the $1 US (or less) if I order it from somewhere.
