A Pocket-Sized Terminal for Mobile Python Hacking

Inspired by the good old days when your computer would boot directly into BASIC, [Le Roux Bodenstein] has created a handheld device he calls “DumbDumb” that can drop you into a MicroPython environment at a moment’s notice. If that doesn’t interest you, think of it this way: it’s a (relatively) …read more

Software Defined Radio Gets Physical Control

Software Defined Radio (SDR) is a great technology, but there’s something so satisfying about spinning a physical knob to cruise the airwaves. Wanting to restore that tactile experience, [Tysonpower] purchased a cheap USB volume knob and set out to get it working with his software. Unfortunately, getting it up and …read more

A STM32 Tonewheel Organ Without A Single Tonewheel

The one thing you might be surprised not to find in [Laurent]’s beautiful tonewheel organ build is any tonewheels at all.

Tonewheels were an early way to produce electronic organ sounds: by spinning a toothed wheel at different frequencies and transcending the signal one way or another it was possible …read more

A Mini Vending Machine To Ramp Up Your Sales

A common sight in the world of hackerspaces is an old vending machine repurposed from hawking soda cans into a one-stop shop for Arduinos or other useful components. [Gabriel D’Espindula]’s mini vending machine may have been originally designed as an exercise for his students and may not be full sized, …read more

This RGB Tree Has its Roots in a PCB

[Paczkaexpress]’s RGB tree is a mix of clever building techniques and artistic form that come together into quite a beautiful sculpture.

The branches of his tree are made from strands of enameled copper wire capped with an RGB LED and terminated in a female header. The separate wires are all …read more

This Home-Etched ARM Dev Board Is A Work Of Art

One of the step changes in electronic construction at our level over the last ten or fifteen years has been the availability of cheap high-quality printed circuit boards. What used to cost hundreds of dollars is now essentially an impulse buy, allowing the most intricate of devices to be easily …read more

GigaDevice Releasing RISC-V MCUs And Development Boards

Probably not too many people have heard of Chinese manufacturer GigaDevice who so far has mostly been known as a NOR Flash memory manufacturer. Their GD32 range of MCUs is however STM32-compatible, making them interesting (cheaper) alternatives to sourcing directly from ST. Now GigaDevice has announced during a presentation that …read more

Blue Pill Makes Cheap But Powerful Morse Tutor

[W8BH] attended a talk by another ham, [W8TEE] that showed a microcontroller sending and receiving Morse code. He decided to build his own, and documented his results in an 8 part tutorial. He’s using the Blue Pill board and the resulting device sends code with paddles, sends canned text, provides …read more

Building A Development Board For The STM32 G0 Series

When [Andy Brown] recently tripped over ST’s new G0 series of MCUs, he figured after some research that the best way to learn everything there’s to know about the STM32G0xx by making his own development board based around the STM32G081. The result is a Nucleo-style board, breaking out all pins …read more
