We love our clocks around here and we love nixie tubes as well. The combination of the two almost seems to be a no-brainer. With the modern twist of an ESP8266, Reddit user [vladco] built a minimalist nixie tube clock.
The build starts with the nixie tubes, Russian In4s, each …read more
Classic games never seem to have gone out of style and with the emulation powers of the Raspberry Pi, there seems to be no end of projects folks have been coming up with. [Chris Mills] project is a great looking monitor to get his Commodore 64 fix by combining the …read more
The Raspberry Pi is a great platform for running retro video games, and with the addition of some buttons, a TFT screen and some speakers it’s relatively inexpensive and easy to get a working console up and running. If you have access to even a cheap 3D printer, a good-looking …read more
When it comes to managing ingredients and baking at a professional bakery, we know that most people would turn to an SQL database and emacs. Really, what else do you need? Okay, so maybe there are a few who would think that emacs couldn’t help you with this, so, here’s …read more
Sometimes you have an idea, and despite it not being the “right” time of year you put a creepy skull whose eyes tell the time and whose jaw clacks on the hour into a nice wooden box for your wife as a Christmas present. At least, if you’re reddit user [flyingalbatross1], you do!
The eyes are rotated using 360 degree servos, which makes rotating the eyes based on the time pretty easy. The servos are connected to rods that are epoxied to the spheres used as eyes. Some water slide iris decals are put on the eyes offset from center …read more
People love their tech, and feel like something’s missing when it’s not there. This is the story of one person’s desire to have the venerable trackpoint in their new keyboard.
[Klapse] loves a Lenovo old-style non-chicklet keyboard, so, despite the cost, five were ordered. They very quickly ended up with keys that didn’t work, although the trackpoints still did. After buying a sixth which ended up the same, [Klapse] decided that maybe giving up on the Lenovo keyboards was the best idea. A quick stop at a local store scored a fill-in mechanical keyboard, but in the back of [klapse]’s …read more
When it comes to guitar effects pedals, the industry looks both back and forward in time. Back to the 50’s and 60’s when vacuum tubes and germanium transistors started to define the sound of the modern guitar, and forward as the expense and rarity of parts from decades ago becomes too expensive, to digital reproductions and effects. Rarely does an effects company look back to the turn of the 19th century for its technological innovations, but Zvex Effects’ “Mad Scientist,” [Zachary Vex], did just that when he created the Candela Vibrophase.
At the heart of the Candela is the lowly …read more
Using LEGO Technic gears and rods seems like a great way of bringing animation to your regular LEGO creation. Using gears and crank shafts you can animate models from your favorite TV show or movie like LEGO kinetic sculpture maker, [Josh DaVid] has done when he created a spinning TARDIS. Crank the handle and the sculpture spins through space and time.
The large gear stays in place. The hidden gears, turned by the crank, rotate a shaft from below that goes through the large gear making the TARDIS rotate around the main axis. Connected to the TARDIS model is a …read more
[James Bruton], from the XRobots YouTube channel is known for his multipart robot and cosplay builds. Occasionally, though, he creates a one-off build. Recently, he created a video showing how to build a LED ball that changes color depending on its movement.
The project is built around a series of 3D printed “arms” around a hollow core, each loaded with a strip of APA102 RGB LEDs. An Arduino Mega reads orientation data from an MPU6050 and changes the color of the LEDs based on that input. Two buttons attached to the Mega modify the way that the LEDs change color. …read more

[Matt Bradshaw]’s entry in the Hackaday Prize is Polymod, a modular digital synthesizer which combines the modularity of an analog synth with the power of a digital synth. Each module (LFO, Envelope Generator, Amplifier, etc.) are connected with audio cables to others and the result is processed digitally to create music.
The synth is built with a toy keyboard with each key having a tactile switch underneath it, contained inside a wooden case upcycled from a bookshelf found on the street. Each module is a series of potentiometers and I/O jacks with a wooden faceplate. The modules are connected to …read more
