It is getting harder and harder to tell homemade projects from commercial ones. A good case in point is [Mirko’s] all band radio which you can see in the video below the break. On the outside, it has a good looking case. On the inside, it uses a Si4730 radio which has excellent performance that would be […]

This project is without doubt the most complex I have undertaken, with sixteen IV-11 VFD tubes, two Arduino Mega cards, ten LED Neon light circuits, a servo, an electromagnet, two MAX6921AWI IC Chips, five DC power supplies, a HV power supply, two DC Volt meters, a DC Amp meter, FM stereo radio, 3W power amplifier,

In ridiculous times, it can help to play ridiculous instruments such as the slide whistle to keep your bristles in check. But since spittle is more than a little bit dangerous these days, it pays to come up with alternative ways to play away the days during lockdown life. Thanks to some clever Arduino-driven automation, [Gurpreet]

Electrical engineer and electronics hobbyist Etienne at Etimou based in Clermont-Ferrand, France has created a new open source development board in the form of the Arduino RF Pro Mini. The creator of the Arduino RF Pro Mini open source development board Etienne, explains a little more about the inspiration behind the project. “I’ve loved Arduino

Recently, I came across RDA5807 module which is an FM Radio Tuner in a very tiny package. It is very cheap and uses I2C protocol for communication which means that only two wires will be required to talk to the IC. Less wiring! My mom used to listen to the radio every day while cooking food before
This Instructable describes a lower-cost, battery-powered wireless IOT sensor layer for my earlier Instructable: LoRa IOT Home Environmental Monitoring System. If you haven’t already viewed this earlier Instructable, I recommend reading the introduction for an overview of the capabilities of the system which are now extended to this new sensor layer. The original LoRa IOT Home

Readers of a certain age will no doubt remember the external modems that used to sit next to their computers, with the madly flashing LEDs and cacophony of familiar squeals announcing your impending connection to a realm of infinite possibilities. By comparison, connecting to the Internet these days is about as exciting as flicking on

Cablecams are a lot of fun, but they’re not inexpensive, even if you need just something small for your action camera. There are commercial solutions out there, like the Wiral Lite, but they’re pretty expensive for what they are. Perhaps even more so than the camera you’re mounting to it. When Kasper at MAKESOME was asked by his friend

There’s no doubt that the RTL-SDR project has made radio hacking more accessible than ever, but there’s only so far you can go with a repurposed TV tuner. Obviously the biggest shortcoming is the fact that you can only listen to signals, and not transmit them. If you’re ready to reach out and touch someone,

Sometimes the best way to figure out how something works is to make a model of it. 3D-modeling software makes it possible to do the job in silico, and sometimes that’s enough. But to really get inside the designer’s head, executing a physical model, like this quarter-scale RC-controlled Perseverance rover, is a great way to go. If
