From Hackaday Supercon last month in Pasadena, California:
Samy Kamkar is well known for many things, but lately it has been his hardware security hacks that have been turning heads. The nice thing to know is that, despite not having a background in hardware, Samy is able to run with the best of hardware researchers
al1 created this remake of the old Texas Instruments TIL305 display with tiny surface mount LEDs:
TIL311 had a alphanumerical brother the TIL305. This was a 5×7 LED matrix in the same form factor
Here is a video of reDOT in action:

ALKR has shared the board on OSH Park:
This is the continuation of a series where I create a PCB in every software suite imaginable. Last week, I took a look at KiCad, made the schematic representation for a component, and made a schematic for the standard reference PCB I’ve been using for these tutorials. Now it’s time to take that schematic, assign…
Over the last decade or so, battery technology has improved massively. While those lithium cells have enabled thin, powerful smartphones and quadcopters, [patrick] thought it would be a good idea to do something a little simpler. He built a USB power bank with an 18650 cell. While it would be easier to simply buy a USB…
We don’t always JTAG, but when we do, we use a Black Magic Probe. It’s a completely open ARM-chip debugging powerhouse. If you program the small ARM chips and you don’t have a BMP, you need a BMP. Right now, one of the main producers of these little gems is running a Kickstarter where you…

Ever since Jimi Hendrix brought guitar distortion to the forefront of rock and roll, pedals to control the distortion have been a standard piece of equipment for almost every guitarist. Now, there are individual analog pedals for each effect or even digital pedals that have banks of effects programmed in. Distortion is just one of…
MatthiasR is building a scanning tunneling microscope:
At the end of last year i started collecting information about needed system components like the vibration isolation, the tunneling current amplifier, the z-height controller, the coarse approach mechanism and so on
Here’s a video of his DIY vibration isolation system:
For the past year, I’ve been organizing a very special project over on hackaday.io. It’s the Travelling Hacker Box, a box full of random electronics junk, sibling to the The Great Internet Migratory Box Of Electronics Junk, and a project that has already traveled more than 25,000 miles. Earlier this month, I said the Hackerbox…

Jakub Polonský of Kaktus Circuits created this programmable electronic load that sits on top of an Arduino:
Electronic loads are used to draw power from a source at either a constant current or a constant voltage. This comes in useful for things like battery discharge testing or making sure that PCB you designed can actually power those motors without releasing the all important magic smoke.
The kit is sold on Tindie:
MightyWatt turns your Arduino Uno R3, Arduino Zero (M0/M0 Pro) or Arduino Due into an electronic load capable of dissipating 70 Watts in a very small form factor. Ideal for testing power supplies, batteries, fuel cells or power amplifiers.
Design files and source are shared on GitHub:
This is the continuation of a series of articles demonstrating how to Create A PCB In Everything. In this series, we take a standard reference circuit and PCB layout — a simple ATtiny85 board — and build it with different PCB design tools. Already, we’ve taken a look at the pre-history of PCB design with…
