Behold the insane genius of my SMD layout on strip board to test my design with the SMD components I bought, before I get a custom PCB made. #KiCAD #PCB #electronics

Some new PCBs arrived today, once I put one or two together I might make a bigger post about them.

Hmm, #PCB OSP is interesting. I have my first board.
Everything I am told says it is a non conductive layer that will survive several re-flows.
My first board is clearly conductive pads.
So sounds like I don't need solder paste on bare pads after all. Fun.

My main technology platform, which I use to learn how to design electronic kits and enclosures—the “FireFly Solar,” is now in the stage of “mass production”.
The FireFly is basically just a Morse code beacon that transmits at dusk for some time a programmed short message. It is battery less using a 50F supercap, solar charged.
The main idea behind this project is to gain some design skills. Essentially, I want to reduce the size as much as possible without using SMD components. So most people with an smaller solder iron can do it as a weekend project. This technology platform combines mechanical work (enclosure), programming (Attiny85 coding), PCB design, and circuit design.
Currently, a prototype is hanging outside and do his job, so I can test the enclosure and how it works. To do more tests I started to build some more.

@aislerhq I built a litter tray on a load cell for my old cat that had several issues and I wanted to track his weight. It's just two wooden panels with the load cells that are placed under the litter box and an ESP32 S2 based PCB with some parts for the load cell, a display and a knob. I also added a buzzer, so it always plays a nice melody when the cat did its business 🐈️ 💩 🤣
The measurements are stored in a CSV file on the ESP32's flash memory and can be displayed with the webserver that runs on the microcontroller. -

What are the chances of my first PCB actually working? It's an ultra low noise USB power distribution board for wing mounted cameras. The power LED at least lights up! I have to program the USB chip which is a one time deal 🤞
After I fully test this, I have four to give away.

Been meaning to finish this for a while.
Small #PCB, #ESP32S3, all GPIOs on pin pads. USB-C, and battery charger circuit, ADC for battery level, and works a 3.7V LiPo.
Uses TPS22916CNYFPR to manage power, so when off it is almost zero current from battery. CPU can then make it stay on.
Also has two of them to control power to two switch output power pins, as well as two fixed output pins.
And a WS2812 LED as well.
I have not ordered any, but let me know if interested. All on my #codeberg.

Практический реверс‑инжиниринг источника питания Murata
Один из лучших способов изучить силовую электронику — это реверс‑инжиниринг качественных изделий. Недавно я полностью воссоздал DC/DC‑преобразователь Murata мощностью 369 Вт — от многослойной печатной платы до принципиальной схемы и конструкции магнитных компонентов. В этой статье хочу поделиться с вами своим практическим опытом реверс‑инжиниринга импульсного источника питания RBQ-8.2/45-L48NBL2-CIS2.

I really like the design of the EMF Explorer badge by @drc3p0 which I had the pleasure of soldering up at #Emf2026 , it has a really creative use of removing solder mask to let light from an LED on the opposite side shine through for a great effect. I am inspired to make my next PCB project be more arty and more like a finished product than just another board. #emfcamp #pcb #electronics

Have I mentioned I’m working on #synthseqr 3.0? Things are getting really serious. I have all my parts in my inventory and my order of five #pcb are arriving Friday. I #3dprinting’d a stand in for the pcb since #kicad will let you do that, and I did a test fit of the physical interface parts. It’s starting to feel real!

Satisfying Tech Build: Full Assembly & Packaging of USBbridge KVM 2.0
I've uploaded a full video showing the entire USBridge-KVM 2.0 assembly process, from the bare PCB to packaging for tech bloggers. If you're interested in seeing how the device is created, this video is for you.
Currently, all assembly is done by hand to personally guarantee the highest quality at this stage. Factory assembly will be next.

This is the first I have heard this #EDA tool. It's a fork of KiCAD, but doesn't look like it's been updated in over a month, nor does it look like it has a user base. However, it sounds interesting. https://www.zeo.dev/

Вводим рейтинг по алкоголизму
Алкометр, который сохраняет результаты на веб-сайте в историю, а также позволяет соревноваться с другими пользователями в недельном рейтинге. На проект ушло более 400 евро, один год и несколько ревизий. В статье расскажу о долгом и затратном пути к финальной версии и о том, какие ошибки были совершены.

Origami meets electronics: researchers created conductive circuit traces by folding and cutting a liquid-metal-impregnated paper-like material. An intriguing approach for rapid prototyping, STEM education, and interactive paper devices.
