Dobot robotic cinematography?

I'm a mentor at Higgs Hub, a hardware accelerator in Shenzhen, China. I love helping these young companies and startups learn how to make their products in Shenzhen and develop their companies. One of my favorite projects is the Dobot robotic arm.

Desktop Michelson-Morely Interferometer

If you're in need of measuring  nanometer scale displacements on the cheap, this tutorial is what you've been looking for. Over the years I've had to measure some unusual processes in systems, and one of the most common 'tough' problems has been the measurement of displacement. For mm-scale motion I've used mice (mechanical and optical) [...]

Howto Build a Function Generator

Scullcom has a nice tutorial video series on building a function generator. ...we will design an build a function generator capable of providing a sine, triangle, square, pulse and ramp waveforms. We will be using the XR2206 function generator I.C. A 8 digit 7 segment display will be used to display the frequency. Source: Scullcom [...]

Hack Cheap PID Temperature Controllers

It's great how Derryn uses an off-the-shelf PID controller and replaces a single board with his custom design. Because the design of these controllers is modular, with a power supply board, display board and separate microcontroller board, I've designed a new microcontroller board that has the same physical form factor of the old board. I'm [...]

Pimp My Geiger Counter

Pretty cool thing to see while being irradiated. A couple of years ago I bought a Geiger counter from Sparkfun. It works pretty well albeit somewhat boring; a blinking light and an ascii character via its serial port. Then one day I had an idea: I should make it visually more attractive. I had tons of led-matrixes [...]

Modular Bench Power Supply

I'm sure a lot can be learned from this design. If we ever do a power supply, this will be a great resource. This is a design for an open source, modular bench power supply with enough features to compete with the mid-range commercial units in the $1000-ish range. This project includes features such as [...]

VIPER: Python IoT design suite

With the rise of ARM microcontrollers and development board we're seeing an increase in the use of Python for hardware tasks. As its name implies, VIPER — or “Viper Is Python Embedded in Real-time” — makes it possible for Makers, interactive designers and IoT professionals to create their next connected project in Python for the [...]

Portable Environmental Monitor

Here's an environmental monitor compatible with the Global Radiation Monitoring Network. The portable environmental monitor addresses pollution, the kind that we are unable to see but directly affects our health and causes life threatening diseases such as cancer. Airborne toxic chemicals, radioactive dust and radioactive radon are correlated with cases of pulmonary cancer. Since our biological [...]

The Factory of the World

The Hackaday folks made a wonderful documentary on what's happening in Shenzhen. Of all the places I've been in the world Shenzhen is the one that feels most like home. I am truly fortunate to be here making the T400 and future products. When it comes to manufacturing, no place in the world has the same kind [...]
