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.

Here is a video showing all the swag that a...
At the end of the week, I'm retiring.
What can I say to express my appreciation for nearly 9 years on the community team and managing the roadtest program? It's been a wonderful experience to end my career. I've found my job both in...
I had the network administrators quotidian task of resolving a user dilemma of I can't print. I received the user quintessential response "I didn't do a thing" to questions before taking the printer to my desk to investigate.

Technically Earth Day here in the US is on April 22 but it is generally celebrated for the whole week. Reminded me of it this morning because I need to watch my son's dog while he participates in a cleanup activity in downtown Portlan...
This is the 3rd mystery project - it might be easier to guess, especially once more clues are revealed, but it may still take a while before the full reveal because there are still a couple of parts apparently coming on a very slow boat. Also I'm not...
Intro
I'm only playing hockey once per week this month, so no hockey tonight. This means I have some time to get started on a second mystery project.
The idea of these mystery projects is to add some interactivity to the project blog by sequenti...

I am working with a model railroader to use light, sound and/or motion to create animations in an office tower that is over three feet in height. Plastic people miniatures moving through o...
I posted earlier about putting out my mason bee houses. I haven't been very successful with bees nesting the last couple of years so I thought this year that I would put up a camera to monitor the activity at the bee house. I did a c...
Intro
This is the opening salvo in my 4 project push. Rather than simply presenting a chronological documentary or a report format with objectives and dry design documents, I wanted to make it a bit more interactive, so I presented pictures of the sy...
So, what do we have here? The goal is simple, using a COB LED (230VAC!!!) for occasional lighting where needed, good for home use. Natural white in color, and with a power consumption of 20W, this COB LED could not be used safely, and by that I mean ...
After more than a year of work to tidy up everything, I finally moved from my parents house to my new apartment, living on my own for the first time.
With the move, I managed to gain something that I had wished for a long time: a dedicated space for ...
This is my usual year end summary what I did on element 14 for the past year. I use these summaries as a handy chronological index of my content activities.
2024 was a lean year for Project14 with the departure of Tariq, but I compensated by doing de...
Introduction
One important piece of equipment that is missing in my lab is an electronic load. Lately, I found myself ill so I was forcefully blocked home for few days. I decided to take advantage of this "free time" to try building myself ...

Hi!
I started writing on E14 in January of 2018 when I was first year of college, 6 and a half years later and around 70 blogs here later, I've finally gotten my Master's degree in Electrical Engineering! This site was a crucial part of that journey ...
