I made this 3d printed high torque worm gearbox. It called also winch, hoist or crane. The gearbox uses a 775 12V 13000 RPM (100 Watt) brushed DC-motor which it has 0.074 Nm torque and 13000 rpm. This 3d printed gearbox had a gear ratio of 98:1. So the...
So I wanted a small clear container to hold my mini projects. I found these Amac plastic boxes at The Container Store and they are fairly inexpensive. The 1"x2" ones are about $0.59 apiece. So I bought a clear one and a smokey one.Taking some quick measurements,...
Sketch of the electronics Its heart is a Teensy 3.2 microcontroller board. It is fast, has plenty of peripherals and is easy to use due to Arduino compatible libraries. I use an H-bridge IC, the L293, as motor driver, allowing to drive in reverse. It...
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...
When my station isn't in a radio silence and doing really Recon passively and connect my wire or buy 5G or Wi-Fi it will have access to my personally trained large language model, convolutional neural network, with several additional modules and an agent...
It's intended as an educational toy for my 2 year old son. The idea is that he plays with letters and numbers and eventually spelling and maybe even math.As mentioned above, there is a PS/2 keyboard attached to an ATMega328-P programmed using Arduino....
Video GenerationThere are several very good references for understanding how TVs are controlled by a pulse sequence. I particularly liked the Stanford EE281 Handout #7 entitled "TV paint". Also very useful were Software generated video, by Rickard Gunée,...
I decided to build a FP with 8-bit exponent and 9-bit mantissa (and with no NANs, infinities, denorms or rounding).The sum of the bit-lengths (plus one sign bit) means that the FP number fits into a 18-bit M4K block word on the CycloneII FPGA. The 9-bit...
The plan here is to build up intuition for HiD representations in parallel coordinates:points -- The basic representation of points as lines in PC.lines -- The observation that lines map to points in PC.planes -- Hyperplanes can be detected visually.clusters...
The Circuit The circuit is a standard pulse generator using two 555 timers (in a single package). Approximate rate adjustment is 1-100 Hz, pulse width is 1 ms-0.5 sec. In single pulse mode, one pulse of the set width is generated when the trigger button...
The outer shell material is black expanded pvc painted with blacklight sensitive acrylic paint. The UV paint was actually transparent, so there's a layer of white primer underneath. The "frame" is just small segments of 2"x2" anywhere the plastic forms...
The Arduino Bluetooth Smart Car has the function of Complete tracking, obstacle avoidance, infrared remote control and Bluetooth remote control. It is a MCU study and application development system base on Atmege328.The greatest feature is that you can...
The project has been scripted in MATLAB because of it's amazing matrix math functions and simply because I had it installed on my laptop.What I eventually would like to do is develop a SLAM (Simultaneous Localization and Mapping) algorithm to generate...
The multi-Function automatic move smart car uses an MCU development application system and a 4-wheel driver system,the core of which is arduino Atmega-328P.It can realize multifunction,such as tracking,obstacle avoidance,remote control and some other...
