When Roamer's bumper is depressed, there are five possible "backup and turn" scenarios--the activation choice is random.After 30 seconds of forward movement (stuck spinning wheels without depressing the bumper or long distance), she backs up and tries...
A quick survey showed that the Braille display is an electromechanical device that can fully replace traditional paper Braille and provides the access to any electronic text. Although there are a great number of speech synthesizers and myriad audiobooks,...
Making a DIY Photoshop Editing Console What if there was something that we could use to quickly change or swap between the tools in Adobe Photoshop with just one button push? Or, say you’re editing video clips and want more control over your brush size...
There are a lot of dot matrix display projects out there ranging from chopped up LED strips glued to a board all the way to custom designed modular circuit boards. Given this project is geared towards high school kids with some basic electronics...
I'm finally starting to revamp and equalize all my details pages so that the projects can be better understood and information hidden within the depths of logs can be more easily found. The below is the old Details page. Notable Tetent projects, sorted...
[Published 21 Aug, 16:16] As I said in the previous log, unlike most cheap laser engravers and 3D printers with attachments, the Suspense has nearly everything for safe and effective laser cutting use. I'm not interested in engraving, and Klipper...

Recently, we made a all-metal Raspberry Pi robot car integrates mecanum wheels chassis and 5DOF visual robotic arm. We innovate some interesting applications based on Raspberry Pi’s AI power. Introducing MasterPi by Hiwonder. MasterPi’s chassis is composed...
Competing with TensorFlow Lite for Microcontrollers Using the public magic wand dataset For my first experiment, I used an official TensorFlow Lite MagicWand example. The trained TensorFlow Lite model is built into the Arduino SDK and is described in...
NTC and PTC are known as thermistors, which can be further known as temperature-controlled resistance. Now something is related to resistance but how it works and which type of circuits can be designed using these components. Let’s know the working concept...
Monday, 14:46, 23/01/2023 Well, I'm creating this other project log because my mind is a weird as ever. Every time I hit a wall, I feel like I didn't look up all the ways in this labyrinth of headaches that I call "project". So, I will try to look up...
Current state of the project It’s no longer just a collection of random bits and pieces glued together. This time I’m actually happy with how it works and looks. By no means is it perfect, but it’s getting closer. You can watch this video if you want...
To make sure the shortest distance also move faster in long straight paths, we require a moto speed control system. Along with that we need a PID control system to find the fastest safe seed way to cover the distance in short time. The focus is to have...
Design Description Overall, the GRIP consists of sensor inputs sent and processed by the ESP32, and then data sent to the web-server through websockets. The web-server then also pulls the 3D hand models from a github repository based on the sensor input...
In the previous log page I walked through the history of the enclosure part of "frame+enclosure". This entry describes the latest iteration. It's all kinda deep weeds and I don't know if anyone will ever actually read it. I wrote a lot about...
