This project is an open source (hardware & software) DDS generator, based on: smart TFT module, AD9834, LM7171 fast amplifier. The homemade function generator is a quite common project on the internet. We can find different ways to do it: – The quick & dirty way based on a DDS module bought on eBay – The […]

Here’s a fun system designed to take care of some of the headaches involved in breadboarding a circuit. It is is a simple set of template files drawn to scale with real world electronic components. Using a vector drawing program you simply move the components onto the breadboard template, draw a few wires and print […]

Over ten years ago, I put up a web page with detailed instructions on building a simple electric motor based on one from the Beakman’s World TV show. I called it the “Beakman’s Electric Motor” page and over the years it has had hundreds of thousands, if not millions, of hits. Realizing that just building a motor, […]

Researchers at Tohoku University in Japan have developed a new low-cost flat panel light source that could pioneer a new generation of brighter, cheaper and greener lighting devices to rival LEDs. The device uses arrays of highly conductive carbon nanotubes to deliver evenly-distributed illumination with high efficiency and a power consumption as low as 0.1 […]

UPDATE 22-12-2014 Instructables user mattpbooth has updated the code and is hosting it on github: https://github.com/mattpbooth/ArduinoNESController… Thanks Matt! UPDATE 03-12-2011 Replaced a println with print (derp). UPDATE 01-12-2011 Remade all code from scratch. Remade ‘ible code section; Now includes a ‘Processing COM port config for dummies’ Ladies and gentlemen, I proudly present 8bit pleasure.. yours […]

In this project, we will demonstrate how to build temperature sensor circuit using a LM35 sensor. As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay thi temperature to us back in degrees celsius. The IC we will use to measure the temperature is the LM35 IC. We will […]

Centrifugation is a powerful method for isolation of compounds such as DNA, proteins, oil or membrane vesicles from a complex mixture. The RWXBioFuge was designed to bring this powerful tool into the hands of labtechnicans, scientists, hackers, makers, diybio-ers and those who cannot afford to procure A-label equipment in low-resource settings. It may also be […]

What is a tilt sensor? Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances. Sometimes they are referred to as “mercury switches”, “tilt switches” or “rolling ball sensors” for obvious […]

If you ever wanted to integrate RFID functionality into your project, this small tutorial might help you accomplish that. I used the RDM630 module from seeedstudio in its UART version. It comes on a small board with presoldered connectors which fits perfectly on a breadboard. You only need to connect the antenna to the two pin socket. […]

This Application Note from Microchip provides a reference design for building a non-invasive blood pressure meter using the PIC24FJ128GC010 microcontroller and MCP6N11 instrumentation amplifier. A digital blood pressure meter measures systolic and diastolic pressures by oscillometric detection. Microchip’s digital blood pressure meter demo can measure blood pressure and pulse rate during inflation. The Measurement While […]
