annmarie.p.thomas I'm an associate professor of Engineering and Entrepreneurship at the University of St. Thomas in Minnesota. There I run the Playful Learning Lab, where we developed Squishy Circuits, and other playful ways to approach education....
Dan Maloney11:57 AMHi Raj, welcome aboard! We'll get started in a minute or two Dan Maloney12:00 PMHello and welcome back to the Hack Chat. I'm Dan, and I'll be moderating today along with Dusan as we welcome Raj Nakaraja for a chat about Open-Source...
IntroductionI've owned a MicroKim by BrielComputers for years, but it had been defective for a long time: as it turned out, the EPROM was malfunctioning. This project describes how I found out what the problem was, and how I fixed it. And hopefully it...
This project is based on PIC24EP512GP806, which has 52K (53,248 bytes) of Data memory and 512K of Program memory. CPU speed is 140 MHz (70 MIPS), but here it runs at 120 MHz (60 MIPS).Due to the limited amount of RAM, frame resolution is 220x220 pixels,...
Overview and GoalsHello, interested reader. I have benefited so much from other people's blog posts, both in my hobbies and my professional life, that I decided it was high time I contributed a little. I hope that someone finds it useful.I've been interested...
Hi!Today I'm going to tell you about Alice's power management and power structure. As for today, it is like this:It's pretty simple and mostly made of ready-to-go modules. This is one of my beliefs - projects like this are better if they're modular (modules...
Jason Kridner @AdityaPrakash23 I can clearly say yes because you say "very basic". The big question is how basic is basic. A BeagleBone can do face recognition using the OpenCV demo code (unoptimized) at about 5-10 frames per second. Lots of...
Sophi Kravitz : Let's get started with an intro about yourself from @Jac Goudsmit Sophi Kravitz : questions/ discussion go in the comments of the event page: https://hackaday.io/event/28313-reverse-engineering-the-digital-compact-cassette...
The "Tingle" is a wearable device designed to combat body-focused repetitive behaviors (BFRBs), especially trichotillomania (compulsive hair pulling) and excoriation (compulsive skin picking). Prevalence of body-focused repetitive behaviors (BFRBs) ...
Turning my attention now to the Explodophone 2.0, I wish to explore how to make sudden, brief, loud sounds to excite the resonant modes of the tuned tubes-- a snap, crack, pop, or bang (a SCPOB). Small real and thought experiments had me thinking about...
When I decided to release Sawppy to the world, I thought briefly about how to best organize all the information I want to convey for rover assembly. I quickly fell into a state of Analysis Paralysis and, as a path out of that state, decided that it was...
This was a long and tedious 3 stage process involving building up a specialised Mobile SSD version of caffe, converting the resulting trained model to Intel OpenVino format and then deploying it on the Raspberry Pi. Fortunately, the results were 'not...
It's been a bit of a battle, with a steep Python learning curve, but finally I created a single Python file that enables a time stamp, detection class, confidence and bounding box coordinates to be sent to the Arduino base station. Obviously, there's...
1. A little bit of theory Between 291,000 and 646,000 people worldwide die from seasonal influenza-related respiratory illnesses each year. iF°EVE will change this. iF°EVE will be a life-saver like a defibrillator or a rescue helicopter. First...
Abstract: Neuroscience is being widely explored to develop more interactive brain computer interfaces for control applications. The objective is to enable a computer to read and display thoughts of a human using an Electroencephalography (EEG) device...
