#electonics — Public Fediverse posts

I remember being a young kid playing with this thing, Mattel Auto Race. It's the first electronic game I played with and I remember being instantly hooked and my life forever changed.

#Electonics Fedi — in the UK — can anyone recommend a clamp meter capable of measuring DC amps that is worth owning, preferably under £50, ideally more rather than less "under" lol.

Ideally it should also log min/max.

My current cheap TackLife clamp meter has always seemed fine for AC mains wiring use, but I'm struggling with DC car electronics where it always seems to be claiming it has detected AC amps and is giving me definitely weird numbers. There seems to be no manual DC/AC mode, it claims to be "auto". (I am trying to assess the state of an alternator.)

[Edit: it doesn't actually do DC 🤦🏻 I am an idiot.]

Anyone have experience with #diy PCB etching? I want to get started with making some pcbs and I've found a lot of videos on how to do the process but can't find a list of what I need to get started.

#diy #electonics #maker

Je me suis fait un petit circuit imprimé rigolo pour tester la sérigraphie en halftone. J'ai voulu me faire plaisir. Je pense que j'ai passé une étape sur le côté artistique de mes PCB. C'est vraiment chouette. Vivement que j'ai des idées sympa pour faire des #kits #electronique pour les scouts lors du #jotajoti

Well of course I installed an LED 😂.

At first I went with a blue one but then decided to make it really special and put in an RGB LED. Because why not? 🙌🏻

Now the mod is complete. Next stop - replacing tone sucking pedals with decent ones and maybe wiring power underneath. But no rush there - I really doubt I'll ever play outside of my place again 😂.

A simple but satisfying fix...

A basic press on battery powered light brought home from a local pre-school were it is used as a learning aid.

It was not turning on, and changing the batteries (4x AA) did not help. Opening it up I saw the problem. The bulb was blown! Also, it was directly soldered to the switch, so replacing it would not be a simple swap.

Instead, I replaced it with a couple of LEDs and a 150R resistor. Then, some hot melt glue to hold it all in place ✔️

@jmrubillon I was wondering if there was something like, say, blue LEDs are 50 times more luminous than green LEDs, but our eyes are 10 times more sensitive to green than blue. So a resistor ratio of 5 - 1, would make the two appear equal, thus when mixed the result would be a balanced cyan. Similarly for yellow, when mixing red and green.

I only want to use the 3 primaries plus yellow and cyan, and the LEDs are either on or off.

I accept that I may be overlooking many facts...

Trying/struggling to "balance" the LEDs in my RGB LED...

Each LED in the RGB package has a different forward voltage so I have worked out the resistor values to give a current to each LED of around 6mA.

However, I am finding that, say, yellow (red + green) is a little too green.

I know that some LED colours are brighter for the same current, and our eyes are more sensitive to some colours than others.

Has anyone managed to work out resistor values/ratios to balance all this?

I needed some more LEDs, so when I spotted a box containing many colours, sizes and types and, I thought that was just the ticket. Lots of LEDs and lots of colours what could go wrong, I mean can you have too many LEDs - 350 isn't too many, is it 😉

This is what arrived! Not like the picture at all 😱

Now to be fair, they are the colours and type exactly as per the label in the lid - I tested 1 of each to be sure. However, I think I would cry if I dropped the box and mixed them up!

Making progress on my PCB editor software suite. Named MangoCAD after a family pet (African Grey) that recently passed. Will be file compatible with a certain bird-themed software product. Still very alpha level and can't actually edit anything yet, but showing promise. Open Source here for the morbidly curious: https://github.com/maehem/mango-cad #mangocad #javafx #java #PCB #electonics

NE555 Waveform Generator kit... Construction progress update 2.

Active parts, IC socket and header pins soldered.

As has already been commented upon, the PCB is in a handy clamp. This securely holds the PCB on the edges and allows me to place the components on the top side, then flip it for soldering.

I may be 50 but I still like taking things apart and putting them together again. In this case, the thumb joystick in the Joy-Con is worn out, so I'm replacing all the switches & springs.

In today's awesome solution in search of a project: a $19 RPi Pico glued to the back of a 1.28" LCD screen, with an accelerometer angled gyro. Add a battery and you have a watch that can be programmed with MicroPython.

These components are sooooo tiny, I really hate soldering them (0402 SMT mostly). Here is one compared to the tip of a mechanical pencil to give you an idea.

Of course the one chip i needed to roast with the soldering iron repeatedly in order to fix a stubborn solder bridge is the same chip that costs 30$ each, and the last chip i solder.. FML.

Oh well assuming i didnt fry this thing its actually coming along nicely. The missing trace i had to hack in is ugly but the fact i got it soldered on at all (had to scrape away some solder mask to get to a via) is impressive. Lets hope this thing works when im all done...

@Electronics

FUCK! Somehow I missed a single trace when I sent my boards off to get prototyped!!! At least its not a production run, but still this is super annoying. I'll have to jump it with a wire but might cause some RFI, not happy about this at all!
