NEW 6 MM POTENTIOMETER FOR HIGH TEMPERATURE LEAD-FREE SMD PRODUCTION

Piher Sensing Systems has re-designed its popular PT-6 Carbon Potentiometer for high temperature lead-free SMD production. High-temperature plastics, flat suction areas for vacuum pipettes optimum assembly and a new pad design enables PIHER’s customers to employ automated placement of this components on their circuit board using reflow solder and thus simplify their manufacturing processes. A […]

SAVE MONEY AND HAVE FUN USING IEEE-488

A few months ago, I was discussing the control of GPIB equipment with a colleague. Based on only on my gut feeling and the briefest of research, I told him that the pricey and proprietary GPIB controller solutions could easily be replaced by open-source tools and Linux. In the many weeks that followed, I almost

DEVELOPING AN OPEN SOURCE ELECTRONICS TRAINER

It’s a safe bet that most Hackaday reader’s interest in electronics started at a young age, and that their early forays into the world of hardware hacking likely involved some form of “playground” kit. As long as you didn’t lose any of the components, these kits promised the user that hundreds of possible projects were

Nui – IR Volume Controller

Nui is an IR controlled volume controller for analog audio. It sits between your audio source and speakers and can amplify or reduce the volume using IR commands (and eventually BLE). Why do I need this? It all started because I have my trusty Logitech Z-2300 speakers and subwoofer I purchased back around 2004/5. They

Raspberry Pi Controlled PIR Sensor with Email Notifications

Story This project was made for extra credit in my measurement and instrumentation class but I also wanted it to be something that I would get some use out of. This allows me to make sure nobody has been into my apartment when I am out of town. This code is only set up to

Bright or Not?

In this project we will use the Adafruit Starter Pack for Windows 10 IoT Core on Raspberry Pi 2 components to make a speaking light sensor. This will show how to use an MCP3008 Analog Digital Converter (ADC) chip to interface the Pi2 to three analog components. Two variable resistors (potentiometers) and one CdS photocell.
