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...
I received this surprise swag bag last week, but unfortunately I was not able to make a post because I was having problems with my desktop. Now that the issue has been resolved, I am finally able to share it.
First of all, I was completely surprised ...

Some time ago, I occasionally bought an HP 5082-7010 LED display, which I did not have time to test if working properly. Today I decided to do this with the help of Analog Discovery 3.
The HP 5082-7010 is a single-digit red LED numeric display modu...
I received by Swag bag yesterday, Being mentioned as a Rising Contributor in 2025 Year in Review & Celebrating You It has been a honor to be part of this community. I started being active on this community almost an year ago and ...
I was taken by surprise when a package had my name on it and it wasn't something I remembered ordering.
It was full of swag from e14.
Happy days. Thank you so much. It's always appreciated.
As a fan of e14 I just love the fan... after la...
Today, I decided to check the pattern generator and logic analyzer features of the Analog Discovery 3. I have used a Microchip development board from the Curiosity Nano series with AVR16EB32 MCU, as a device under test unit. The AVR16EB32 MCU has su...

I just arrived home from an extended trip and what did my wandering eyes see but a swag bag from E14.
My friends and family are enjoying the spoils. I typically share the stuff. The miniature USB fan I think I will keep. That has ...
Thanks E14Alice and element14 for the surprise swag package for contributing to the community.
Here is a quick video showing all the goodies.....

Thanks Element14 and E14Alice for the 2025 Contributor Swag package that arrived just in time for my 14th Anniversary next Tuesday! Very rewarding (literally!) to be part of this engineering community. Looking forward to participati...
It looks like the Easter Bunnies have been busy again at e14.
Many thanks for the mention in 2025 Year in Review & Celebrating You and many thanks for all the lovely surprise swag received today. Much appreciated.
Thank you element14 and E14Alice ! Earlier this morning, a package appeared on my front porch. What a great way to start a Monday. And inside the package was... e14 stuff!!! Whoo-hoo!!!
As you can tell, I'...
Touted as "Listen to music through your mouth", the TastySounds Audio Lollipop is all gimmick, and depressingly one-time-use. Even if you're handy with an exacto-knife, or your favourite decommissioning tool of choice.
These 'sweets' come 'toys' have...
Today I have checked the adapter for an impedance analyzer which I recently received. I previously did some tests using a breadboard during which I manually chose resistors for measurement, but this adapter makes measurement easier, because we could...
Today, I performed a quick check of a network analyzer without using a BNC adapter (with differential input). The circuit under test was a simple RC low-pass filter, with a cut-off of around 294 Hz. Here is a schematic with indicated connections for ...
The waveform generator built into Analog Discovery 3 has a lot of features, from simple predefined signals to complex custom ones. Today's I wanted to check the sweep and modulation options. The first test was with signal swept from 1 kHz to...
Today, I built a simple relaxation oscillator with the 74HC14 integrated circuit. The purpose of this circuit was to get a reasonably fast rising time pulse generator. Here is measurement from SDS824X HD:
It is observable a noticeable ringing. For ...
element14 sent a unique award to commemorate passing the 1 million point milestone.
It wasn't expected and not something associated with the Ayrton level (12), but it was a very pleasant surprise.
