A quick and dirty introduction to the PyPPMHere are a couple short summaries of the "what" and "why" behind my PyPPM project.Still interested? Awesome! Read on, friend...How an Earth's Field NMR (EFNMR) experiment worksThe first-revision PyPPM...

IntroductionE-textiles (a.k.a. soft circuits or wearables) is a rapidly growing field of electronics. Projects generally consist of interactive circuits embedded in textiles using conductive thread and Arduino-based microcontrollers. The components commonly...
Prototype system design:The specific scanning techniques that may be tested include: Area-basedFourier transformTopographicCanny edge detectionHough transformSIFTSURFBarcode-type scanLibraries used: OpenCVPILpyinsane (Sane API) For storage, the cases...
Usecase:In Christiania (freetown in Denmark) we have an off-grid heating infrastructure running with wooden pellet stoves. To send out bills we need to be able to read the meters installed at all households in a fast and easy manner. Before we used pen...
In addition to the wireless module, I started working on infrastructure to support a network of devices. I'm using a USRP to coordinate a group of these things and respond in real time to changes in the spectral environment. This is really important...
Here is the Open Source laser cutterHardware:The entire machine is moved by low cost servo motors with a close-loop encoder feedback. mxl timing belt and printed sprockets are used for movement.The machines have a cutting size of 2'x3' for the...
Inspiration:The SolarSurfer project started because we were looking for something cool to do. Being surfers and engineers, the project was a perfect fit. When we first started, we had no trouble finding the right microcontroller, sensors, GPS,...
A PQ60 standard board looks something like this:The QubeCast Max is a radio board based on a NiceRF RF4463F30 radio module.This module is based on the Silicon Labs Si4463 RF chip. This is an integrated ISM band transceiver IC, normally used...
MotivationI have four little kids and a full time job, so I don't get out to the apiary as often as I'd like. I keep the hives healthy, but they do occasionally fill up most of their available space with nectar and slow down collection before I can get...
Cyberia Makerspace is located at 6800 E 30th St Indianapolis, IN 46219. We hold an open workshop for the public on the first Saturday of every month from 1-6pm. Membership starts at $35/mo.
Problem: Previously we had whiteboards that had laminated indicators velcroed on. These were placed on the sides of the partitions between the desks, all faced the walkway so you had to kneel down to write on them. Plus, many were obscured from view...
Ever since my addressable RGB LED strips (WS2812B) came from Aliexpress, I've been fascinated with LED projects. Following up on my success with my Charlieplexed LED clock, I wanted to create something with more Jazz..While browsing google images,...
What's all this for then?The Biotechnology Age is well under way. But like the Silicon Age, I think it will only really explode in growth once the entry price reaches a point where a few college dropouts can afford to build a biotech lab in their parent's...
Background:I wanted a charger for portable power that could be used with solar panels, TEG elements and dynamo. It was also important that the charger could take all available power. I quickly realized that LiFePO4 are the best batteries available. LiFePO4...
