Sometimes a webinar is just another event on your calendar. You join, listen to a few presentations, learn something new, and eventually move on to the next thing.
But occasionally, something much more interesting comes out of it.

I've been looking at the ESP32-C61, and it’s an interesting addition to Espressif’s lineup. All in a compact, low-cost module.
What stands out to me isn’t just the feature list, but how it fits into the existing ESP-IDF ecosyst...
Real quick: IDEC-TUI is a command line utility for reading, writing, and monitoring IDEC PLC registers and assets. Operates over usb serial, and it is still very much a work in progress. However there has been some new features added:

SensoredHacker's On The Line Challange with PLCs, HMIs, Arduinos
R&D from May through June 2026
The original FC6A library began after a work project where I needed to log basically every PLC event in a testing array. I wrote the functions I neede...
The main concept was to build a clock generator that supported at least a 50 MHz frequency. I have decided to use a module with Si5351. This module supports the three simultaneous outputs for which it is possible to set individual output frequencies....
A few weeks ago, I was asked to check the car's radio that had an issue with power on. It was the Blaupunkt Bremen 975, which is one of those radios with Android. The initial check and measurements showed that, from the perspective of electronic...
For a few months, I was the owner of Siglent SDS824X HD, which is a really good device in case of performance and price ratio. But I have decided to perform an upgrade and get one more advanced device which supports higher bandwidth, sampling a...

The Analog Discovery 3 has support for two programmable power supplies with a voltage range 0.5V to 5V and -0.5V to -5V. These power supplies have support for voltage readback, but there is no information about current usage. Even t...
Hi everyone,
I’m working on a small tool idea around STM32 / Cortex-M debugging, and I’d like honest feedback before building too much.
The problem I’m trying to validate is this:
When a Cortex-M firmware crashes into HardFault_Hand...
The WaveForms has a nice feature that allows us to perform characterization of elements like diodes or transistors. By default, it requires a dedicated adapter. However, there is an option to use a breadboard and a simple circuit. For example, to ch...
