I printed case for the small automatic irrigation system I am building. It contains the batteries, the circuit and the little pump. There is a slot to insert a RS233 adapter to program it with a laptop. Maybe in the next iteration I will include an LCD and a rotary encoder, but for the moment it will do. #3Dprint #electronics #Diy #ElectronicsDiy #microcontrollers #irrigation

In the last few days I worked on a new project: a simple irrigation controller for some plants. A PIC microcontroller handles a small pump and a humidity sensor that measures the soil’s electrical conductivity. On this version all is controlled via a serial link. I may add an encoder and an LCD display in a later version. I kind of like programming #pic microcontrollers in assembly. #ElectronicsDIY #Microcontrollers #Irrigation #Electronics #DIY

Version 2 of the #eurorack overdrive module:

- Placed filtering caps closer to op amp.
- Schottkey diodes to protect against reverse polarity.
- Tip normal of input jack connected to ground to avoid noise/hum/interference when nothing is plugged in.
- Unity gain for unused op amp.
- More compact design.

I'm running out of ideas for what to improve. The next version will have drive, tone, and volume controls. #synthdiy #diy_electronics #electronicsDIY

Second exercise in PCB design with #Kicad: a super simple #eurorack overdrive module (non-inverting soft clipper using LEDs). Essential features missing (gain) and probably tons of obvious mistakes but it's my first complete module. #synthdiy #electronicsDIY

That’s all for the Nuova Elettronica number 104-105 from October-November 1985. If you want to have a look, the scan of the whole magazine is available here: https://archive.org/details/Nuova_Elettronica_104_105/mode/1up #NuovaElettronica #ElectronicsDIY

The final section of the magazine was often dedicated to projects sent by readers. They usually only provided the schematic and a brief description of the circuit. It was usually a favourite of mine as it was very diverse and interesting. #ElectronicsDIY #NuovaElettronica

After a forgettable article about magnetotherapy, the next project is a 4A DC power supply, with a switchable voltage output from 5V to 15V. Based on a nice toroidal transformer, it’s a conventional linear design. It was meant to use car radios at home, as most of them were removable so they weren’t left in the car, as they were stolen very frequently. I like the style of the box! #ElectronicsDIY #NuovaElettronica

Then, the “pièce de résistance”, i.e. the Delta computer, that was a nice Apple 2e clone. The guy in the top picture by the way recalls me my electronics professor when I was at the university. @hkz rebuilt it from scratch by redrawing all the schematics in KiCad as well as all the motherboard with minor modifications. He could run my text adventure games on it and I am in awe. #retrocomputing #Apple2 #NuovaElettronica #ElectronicsDIY

The next two projects are a guitar preamplifier that boosts the 3kHz to 6kHz frequency band and a junction tester equipped with a beeper. The latter may be useful, indeed, as the sound is different when the junction is good or in short circuit and you just have to keep your eyes on the circuit you are testing. Of course, there’s no sound for an open circuit. #NuovaElettronica #ElectronicsDIY

Then, we find two other blinking lights projects. The first one is an interesting two-transistor design that used an uncommon circuit. The second one is again a strange Christmas light project based upon a SN76477, that is in reality an audio synthesiser IC they must have had in stock. #NuovaElettronica #ElectronicsDiy

The second project of the #NuovaElettronica 104-105 from 1985 was a simple test oscillator for CB radio at 27 MHz that could be modulated by an audio tone. They used a 74LS266 quadruple XNOR in this project and in another one a few pages after. Probably they had a large stock of them to sell in the kits? #electronicsDiy #electronics

BTW, if you want to test the release candidate of #FidoCadJ, do it now! We are planning to release the stable version as soon as we get enough feedback and we are confident that enough bugs have been ironed out. We would like to have a feedback also about the release process, too. #opensource #ElectronicsDIY #Electronics

Question for the more industrial electronics/electrical peoples here:

I've got a little build on the stocks which requires quite a few wire-to-pcb connections.

The BOM uses TE MTA-156, but those really require a special (absurdly expensive) tool to attach the wires to the female connector.

I'll sodder the wires direct to the PCBs if I have to, but I wondered what other neat, pluggy, inexpensive solutions there might be?

I just did my first electronics repair. Fixed up an old multimeter we had lying around.

It was a simple repair, sure, but there's so much satisfaction in seeing the thing come back to life.

The only thing on my mind right now is that I should've gotten into this stuff way earlier. This is so much fun. ​:blobfoxlaughsweat:​

I teased it last night but I am absolutely thrilled to properly announce the release of PETI Firmware Version 0.4.0, the Sleep and Growth Update!

PETI has been a multi-year project of mine to build a virtual pet that has a retro feel while running on relatively modern hardware, and this update finally adds two very important features to the game: sleeping and evolution! This thing is finally starting to feel like a real toy.

(I also take the time to elaborate on my project roadmap and hint at some possible hardware changes).

Quick blog post for y'all.

The ultra short version: You will see more content of more varied kinds coming through the lab now. It can't all be gizmos in this economy.

I was pretty low energy last week, so I didn't stream much and just sort of plugged away on my own. That also meant I didn't take many notes.

For this week's blog post, then, I thought I'd talk about the roadmap for the rest of PETI. I think if I really focused on it, we might be able to finish the firmware entirely by this time next year, easily. Sooner, if I somehow made it my primary life concern.

Hi #fediverse 👋🏻 I have a question: I’m picking up a thermal camera and can’t really decide between two models: Topdon TC004 or Uni-T UTi260B? Specs seem close and I need the one that has a clearer image for working with small smd components and a better software updates/support. What would you recommend? #unit #topdon #ircam #ircamera #electronics #repair #electronicsrepair #electronicsdiy #ifixit

So among the things I did yesterday that I was putting off for fear of their complexity, but which later turned out to be quite straightforward, was writing a custom export module for the font editing tool we've been using for PETI. This new exporter lets anyone use fontedit to spit out a font in a much more standard format, which can then be edited with any additional tooling of their choice which supports it.

It's an unfortunate bit of yak-shaving, but it should get me unblocked on creating the new glyphs I needed to finish the evolution features and get the next update out to you guys much more quickly.

Having spent a chunk of my morning trying to do SMD by hand, I am now reminded exactly why I wanted to learn reflow.

Anyone got a good ingress into that skillset?

If it's almost 8PM but the UPS tracking says my package will be delivered "by end of day" do you think it will come today?
