Have you ever made a processor? I did. Took me just 12 microchips and a clock generator. The processor can execute several commands, and programs can be written for it. The program code and input data are entered using micro switches, and the state of...
Let's get to some more real-world examples. First, we can look at a color-pill. Pick a color. If you search for "blue pill" or "green pill" or "red pill" and tac "stm32" on to the search, they all bring up useful information. ...
Part of the hits of 2018 has already come out, part - more will please us in the next couple of months. However, it is time to look into the more distant future and take up budget planning for future projects. So, we present to your attention the twenty...
SOT23 vs SOT323 Overview SOT23 and SOT323 are both plastic and surface-mounted packages. SOT23 owns 3 terminals, 1.9mm pitch, 2.9mm x 1.33mm x 1mm body, while SOT323 boasts 3 leads, 1.3mm pitch, 2mm x 1.25mm x 0.95mm...
So if you've seen damn near anything I've done for the last 18 months then you've seen examples of using Reverse Mount LEDs and also manually mounting LEDs upside down. A sample of my projects from 2018, all using reverse mounted LEDsReverse Gullwing...
As noted in our previous column, in the not-so-distant future we’re going to start creating simple circuits using resistors and light-emitting diodes (LEDs), but we first need to learn enough about resistors to ensure we use the right ones when the occasion...
[2 April 2023] So I was researching into input devices, and I had an idea: what if there was a way to use the SpaceExplorer I have in a shelf as a 2D mouse? Hear me out here! The main reason it was in a shelf was because I didn't want...

I ordered some counterfeit STM8S003 recently as the parts dried up and the prices were getting higher. I didn't think much at the time as the seller had been around for a few years and had good reviews. Aliexpress dispute initially rejected my...

I have been interested in smart home systems, automation, and sensors for a long time. I like devices without reference to any manufacturer. So I often use the excellent Shelly Wi-Fi devices. These relays, controllers, and bulbs have an open embedded...
Choosing the right motor for a CNC mill, lathe or router depends on several factors, including the requirements of the project and the characteristics of the motor. Here are some important factors to consider when choosing a motor for a CNC machine:...
1. What is an Arduino? Arduino is an open-source hardware and software platform that is used to build and program electronic devices. It consists of a microcontroller, which is a small computer that can be programmed to control different components...
While discussing with Paul Falstad about a new feature of circuitjs, came the question of which default parameter to propose to the users. For basic simulations, the contact's resistances can be pushed to the limits (on: 1m Ohm - off: 1G Ohm) because...
