I know lots of hackaday readers are HDL specialist and this content may not be useful, but beginner (including me) needs some struggle just for simple application. Here I would introduce "how to make simple counter" using my training board.The training...
Detecting Clean-vs-Messy Rooms using TensorFlow Deep Learning This guide will walk you through the steps to create and use a TensorFlow machine learning model to detect a clean room vs messy room. In our house, we integrate such a model with our home...
What it can do: This radio telescope takes pictures in radio (on frequencies between 10.7Ghz and 12.75GHz). Theoretically, this radio telescope should be able to take pictures of the sky, in radio. If the dish is aimed properly, the results should create...
The idea was quite simple. Buy a linear actuator from OpenBuilds with a stepper motor, attach a camera on top of it, two tripods below, assemble a control box with some Arduino-compatible, WiFi-enabled board and write an Android application that would...
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
LEDs come in all manners of sizes, colors and brightness. To be able to choose the most appropriate ones, we need to know what are they going to be used for. For this purpose, we did some market research on UV curing glues. After checking the datasheets...

Announcing a major new capability: CylinDraw makes for an excellent paper plotter! The hardware needed to enable this capability only requires the addition of a large tube to wrap the paper around and two rubber bands to secure the paper in place....
YouTube How to update CircuitPython firmware This method is suitable for the BPI-PicoW-S3 board that already has tinyUF2 firmware. If the flash of the board is erased or the failure to enter the UF2 mode occurs, you need to refer to the method of burning...
The BPI-Pico-S3 is an ESP32S3 development board that has been fully adapted to CircuitPython, and the TinyUF2 + CircuitPython firmware is installed by default. No need to install any drivers in Windows 10, Windows 11, Ubuntu Desktop, or Mac OS operating...
Are you the type of person who likes listening to good ol' radio like I do? Unfortunately, medium-wave broadcasting has decayed in the last few decades. There's nothing in many areas, even at night when medium wavelengths work best. That’s why the radios...
My daughter loves reading, and I appreciate her hobby as it helps her collect information. To honor her hobby, I will give her a customized bookmark that I made. It will be a symbol of love and appreciation for taking her hobby so seriously...
I'm going to create a stand-alone PSoC project to use the PSoC to read SD cards. I'm going to start with the hardware defines for this project (which should leave the Z80 hardware pins unmolested) and just not download code. For the software piece, I...
