Beacon Controller
Log from Edog - Mini 3D printed Quadruped Robot ✨
As explain, edog will participate in the Eurobot cup. To do so, I need to know the robot position in (x, y) on the table. But I can't use embedded lidar or using triangulation due to its small size and its limited capacity to carry heavy...

New Applications made with STEMCA App Inventor - by my kids :-)
Log from STEMCA Inventor - STEM Education and DIY Amplified
Happy New Year! I invite you to try some new apps we created, in last few weekends, with STEMCA App Inventor (about 2-3 hours per app) for Learn, Teach, Invent, Make initiative! All these can be used without STEMCA Brick. Download and install them on...

Beer Goggles Code Running Windows
Log from Beer Goggles
In order to test full body detection (and see just how fast I can get OpenCv to run on a relatively beefy Gaming PC) I decided the edit my code to run on windows using a hacked Eye Toy webcam.Getting the Eye Toy to run was easy enough, several drivers...

Machine learning object detector isn't as effective as I hoped it would be!
Log from RAIN MAN 2.0 - Blackjack Robot
Over the past couple months, I've been tinkering with machine learning to try and train an object detection neural network that can detect playing cards. The OpenCV algorithm I used (described in this video) works great at detecting cards, but it doesn't...

Rep counter
Log from Silly hardware wishlist
With old age & senility, it gets harder to count reps. There is of course the ages old https://www.amazon.com/GOGO-Counter-Carnival-Manual-Mechanical/dp/B001KX1VW2 counter from grumpy old school bus driver lore. Maybe it was too rooted in...

Raspberry Pi Setup
Instructions from Open Source Air Defense
What I did to Raspberry Pi 3 B (for now)... Do not use NOOBS (I don't think it allows analog composite video output as we need it) Install just RASPBIAN, use 'stretch' update only (I think?).perform: -update pip3perform: sudo apt...

FaceAssure: cloud based pan-tilt security camera
Details from FaceAssure: cloud based pan-tilt security camera
Board Design. We use Eagle to create our embedded board design, including version 1.0 and version 2.0 . Here is the version one, our first prototype for testing of images transmission. As we can see, this version includes WiFi module, MCU and camera...

Face tracker
Log from 3D printed truck
The decision was made to transfer to using a face tracker instead of manually pointing the pole cam. Manual pointing would override the face tracker if the remote control was powered on, but it was expected to disappear. The lion kingdom...

Face tracker 2
Log from 3D printed truck
Face tracking based on size alone is pretty bad & nieve. It desperately needs a recognition step. There is an older face detector using haar cascades. opencv/samples/python/facedetect.py These guys used a haar cascade with a dlib correlation function...

Details from Develop an open source Raspberry Pi OCR system
A good OCR system requires the following: Capable of agile iterative algorithm models, including model training for new scenarios and online deployment of models. Reduce the cost of continuous deploymentThe lens can be changed to suit the needs...

YET Another IR Vein Detector
Details from YET Another IR Vein Detector
The project is based on the idea to create a cheap way to map veins on medical patients in order to canalize them. Knowing there are devices that already do the task, the goal is to achieve it in a cheaper way. In order to do so, the idea is to use a...
