This Makevember project automatically switches between headphones and speakers whenever the headphones are picked up. This issue has bugged me for a long time. When I want to use my microphone, such as when receiving a Skype call, I need to disconnect my speakers and use headphones to avoid echos and feedback from the speakers to the microphone. Having to plug in the headphones each time or access audio configuration is cumbersome and it can wear out the jacks. So I designed an automated switch ...
This is a quick project I cobbled together only days before the Pi Party. It's an epaper badge showing my name and information, but also a slideshow of my recent Pi projects. A portable portfolio and business card, if you will. Geeky and semi useful?     Hardware Software Code Video Hardware  The following hardware components are used in this project: Raspberry Pi Zero / Pi Zero W 8GB microSD card Pimoroni Zero LiPo Pimoroni 2200mAh Lithium Ion battery P ...
Introduction It's fairly geeky to want to make your own flashlight! This project offers over 260 lumens of light output (approaching some typical LED lights for home use) and is powered by three AA or AAA batteries, or a single lithium ion (Li-ion) cell. It was built from scratch in about 4 hours, using whatever I had handy. Here it is not shown, because the light is very bright! I held a 5mm thick sheet of perspex in front of it.   The Circuit for Flashlight 'A' The circuit is shown h ...

Geeked Out Business Cards

Posted by dougw Top Member Jun 11, 2017
I have made a lot of unique business card holders over the years, but I always wanted to make one that could automatically dispense cards. It sounds pretty straight forward, but I know that to make a reliable and simple machine that can do this is not an easy task and there are several risks that turn it into more of a research project than a sure-fire design project. The Project14 Geeky Gadget is a good opportunity to see what can be accomplished, since there are no product sponsors counting ...

  I'm fashionably late to the day's celebration.   And... I bring a project that isn't even complete too!     It's a proof of concept.. and it's a work in progress. Right now it's a 3D printed housing with a 128 x 64 pixel OLED display inside.     Above is a Solidworks 3D model of the whole housing. The plan is to house everything inside the ring itself and run it all off of 2x CR2032 batteries.   If you want to see more of the build, see it complete ...

Geeky Dalek Project

Posted by lahey May 19, 2017
My geeky idea is a Dalek with object recognition and different behaviors based on what it sees. I have recently acquired two 12'' rc daleks, one functioning and one for spares, and the motor section is actually well built. I will use a RPI3 for the image recognition and an Arduino for the movement and obstacle avoidance, so as not to encumber the RPI too much. Trying to find a viable way to turn an optical mouse into an odometer for motion tracking. Any tips VERY welcome.   ...
