Project Overview Video for Hackaday Prize 2023: The End Result The Plan In principle it is simple: by connecting different combinations of binary value resistors in parallel, and assuming a constant input voltage, we can consume any arbitrary amount...
This Project is to add a 2 watt laser module to the WaterColorBot.The Lasers power and controls go through a arduino.The laser will activated by a micro switch which is under the holder (the holder is where the laser and heatsink will be mounted)
This project started some months back. I was given two projectors, one with a bulb, one without. Not wanting to scrap either unit, equally not wanting to spend £100 on a bulb that would be prone to shock and likely to fail, I decided a more serious...
System Design:The assembly is built for my mini-cnc-mill (see my other project), it has a mount diameter of 65mm like my Chinese spindle (0.8 & 1KW have the same size) which means to be compatible with other small CNC.The syringe is 10ccm, mounted in...
The project started out as a 555 timer based flyback driver. I wanted easier control of the frequency and duty cycle, so I decided an Arduino was needed. Normal Arduino PWM frequencies are far too slow for a flyback, so I used a library that...
This probably comes under the "not much of a hack" banner... I guess some purists would suggest that replacing a flat filament tungsten bulb, whopping great wire wound pot, and a large transformer with an LED headlight bulb, cheap'n cheerful LED PWM...
===============STATUS===============AM Status - Version 1.0 - Arrived with no plated holes, guess OSH park can only handle 1 drill file, oops... drilled the holes myself, got useful prototype info and poof that it worksVersion 1.2 - Much better,...
So i really wanted a warm cookie at my desk one day.Rev-01so i took apart a cupcake tray and got the cup. I wrapped a beaker warming nicrome wire around it and cemented it in place with fire place caulk. It was a 150W heater and i found although it cooked...
Frame Ultimately, I have been looking at using some sort of metal (steel or aluminum) tube in a combination of 5/16", 1/4", and 3/16" sizes for the frame of this beast. The frame's tubes in the model have been sized accordingly, albeit solid for model...
Hello! This is my infinity mirror/window project. I hope you find it informative and entertaining.I'll start off with a quick video of the final project. This is running a relatively simple 12-band EQ preset on Jinx.We started with 200 WS2812Bs, and...
First Stage (Audio Modulator):This class D amplifier takes in a mono audio signal as the input to an lm393 comparator. The other input of the comparator is a 60Khz triangle wave using a 555 timer triangle wave generating circuit I pulled off the web....
I'll start the description with the basic specifications of the supply:output voltage range: 0 - 15Voutput current range: 0 - 3Aconstant voltage with current limiting and constant current modesmains earth isolated output so multiple supplies can be connected...
The plan is to design and build a digital bench power supply. As the starting point we have the following:a project metallic enclosure from an old ATX supplya microcontroller, the choice is Atmega8 (or for extended functionality, such as Bluetooth/HC-05,...
I've been interested in radios and communication for a while, and I've always wanted a radio for my car. There's a barrier to entry with mobile radios, however, and most quality units start at $200 or more. My goal with this project is to design and...
Each segment will have about 7 of the ws2812B leds because with a heatsink they have a radius of 1cm and a segment is planned to be 7.5cm long.Diffusion of light: I plan to either sand the glass or to use a thin paper membrane like wax paper. The interior...
