Scratch-Built EV From Hoverboards

Electric vehicles are everywhere now. Even though battery technology hasn’t had the breakthrough that we need to get everyone out driving an electric car, the price for batteries has dropped enough that almost anything else is possible. The hoverboard was proof of this: an inexpensive electric vehicle of sorts that…... [Continue...]

Hi-Tech Tool For Measuring Your Kid’s Height

Sure we can have our kids back up against a wall, force them to stand up straight, and use a ruler on their head to mark their height on the wall, but what kind of hacker would we be? There isn’t a single microcontroller or any electronic component involved! The…... [Continue...]

My Take on Assistive Tech for the Hackaday Prize

We’re in the last few weeks for entries in the 2016 Hackaday Prize — specifically the challenge is to show off your take on assisstive technology. This is a hugely broad category and I’ve been thinking about it for a while. I’m sure there’s a ton of low-hanging fruit that’s…... [Continue...]

Hacker Places To Visit: Musée des Arts et Métiers in Paris

The best way to pull off this deception: tell your significant other that you’d want nothing more than a romantic week in Paris. Arrive in Paris, stash your bags, and then take either the number three or eleven Metro. When you get to the station that looks like the inside of a giant steam…... [Continue...]

Arduino Sketch: The Next Generation

What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated pretty quickly. At some point, things get harder because the Arduino lacks an operating system. There are operating systems that…... [Continue...]

Hackaday Prize Entry: LipSync, Smartphone Access For Quadriplegic People

For most of us, our touch-screen smartphones have become an indispensable accessory. Without thinking we tap and swipe our way through our digital existence, the promise of ubiquitous truly portable computing has finally been delivered. Smartphones present a problem though to some people with physical impairments. A touchscreen requires manual dexterity on…... [Continue...]

Brushless HDD Motor Driver from 9V and Painter’s Tape

Hard drives work by spinning platters full of magnetized data while a read/write head very quickly harvests or changes bits as needed. Older (or perhaps cheaper) drives spin at 5400 RPM, better drives spin at 7200 RPM, and elite drives (that mortals like you never shell out for) spin in the…... [Continue...]

Copper Thermite Explodes and Smolders Successfully

It was quite a surprise to learn that thermite isn’t just rust and aluminum powder, but describes any combination of metal powder, metal oxide, and optionally fuel mixed together in a reactive ratio.  [sciencewithscreens] shows us some of the properties of a copper (II) oxide based thermite. We can only…... [Continue...]

Forgot to mention SARGON 4 as part of my chess program overview…

Very nice, and runs with CGA, EGA and VGA cards: Sargon 4 (and not Sargon IV), distributed by Spinnaker Software, not from Hayden Software (which published the famous first three Sargon versions). It’s playing good, although different from Sargon III, which is not surprising because it’s from a different software…... [Continue...]

Creating A PCB In Everything: Introduction

A few years ago, I wrote a few columns titled Making A Thing. These columns were a tutorial of sorts for several different 3D modeling programs. This column wasn’t meant to be a complete guide to modeling an object in OpenSCAD or SolidWorks, it was just step-by-step instructions on how to make one specific thing with one…... [Continue...]

How to Run a Pagekite Server to Expose Your Raspberry Pi

Last time I showed you how to expose a web service on a Raspberry Pi (or, actually, any kind of device) by using a reverse proxy from Pagekite. On your Pi, you just need a simple Python script. However, it also depends on the Pagekite server, which isn’t always convenient.…... [Continue...]

Panel Meter-To-Bluetooth Hack Hijacks The Display Segments

There are a proliferation of cheap digital meter modules available online for pocket money prices. Current, voltage, frequency, or combinations thereof can all be yours for just a few dollars and a wait for shipping. Unfortunately though these meters are all self-contained units. They do not have a serial port or…... [Continue...]
