Ratch Aurora has got a color sharp memory display with a backlight. A LSM6DSOX IMU for motion tracking. NOR flash to store apps. A vibration motor for notifications and a Lipo battery. Its got 4 buttons called up, down, select and back. Everything is...
You can get the detailed bill of materials on github. But basically you will need:4 IN-1 Nixie tubes STM32F051R4T6 ARM Micro DHT22 temperature sensor if you want temperature display 30 FMMTA42 transistors that are used to drive the Nixies - so no special...
The amplifier is based on 2x2 LM380N-8 that gave a pretty sound on the first tests. Stereo circuit is also doing well, look at the scheme attached to see how I built the whole thing.It needs a 12V voltage supply and give back a 2.5W output power. I linked...
Who We AreWe're a collective of all kinds of people who love to explore science, art, and technology. We love to push boundaries, test limits, take things apart and then put them back together again (they usually still work!). If you think this sounds...
Aims:I don't want to buy an external phono stage, and everything is set up for one inside my amp, so lets build one. First to work out the spec.1. Must work with MM (Moving Magnet) cartridge turntables. These require the least amplification, so are easier...
I am going to be 3D printing a Qi Charging case for my phone. This is a pretty complicated project for something that involves 1 3D printed part, one component module, some wire, and some washers. 3D printing off of the bed using carefully designed support...
This all starts from mapping what contacts go to what keys on the USB keyboard. I decided to use the minimum number of wires and just remap the keys in the emulator. So I went with 2 columns (pins) and 7 rows (pins) , so it's 9 solder points for all...
how this all works there are 4 main parts1.vixen 3 the lighting sequencing software 2.raspberry pi loaded with falcon pi player3. Arduino Nano with a ENC28J60 Ethernet Module (each Nano can control maximum of 240 pixels)4. a load of 12mm WS2811 LED...
This project will be an open source project once the schematics and code are cleaned up a lot. Right now everything is wonderful development mess :)20 Flexible Inputs (ADC, Digital, DAC) with individual selectable voltage ranges12 Bit ADC (SAR)Programmable...
Robots are getting far more sophisticated, far more capable and all this, with less effort. The aim of this project was to learn ROS (Robot Operating System), the assembly of the materials, electronics and all the of the other components that make...
I bought a New Hermes Vanguard 3000 CNC engraver a long time ago without any controller. It is a professional machine that is mechanically sound and has all the components except for the electronics. The plan is to restore this machine to make it fully...
From the picture it looks almost done, but far from it! This was just a layout test. I need to redraw everything, make it smaller and find out the arrangement of the LEDs first. Some things have to be fixed in software, as the original layout for...
This movie illustrates the launch sequence of the model. After pushing the launch button, the crew arm swings back, pulling up the sway arm on threads. Next the crew walkway retracts. At T-8 seconds Neopixels light up the F5 engine plume tubes. At T-0...
I basically copied the Ganglion design, but removed the SD card holder, accelerometer, and the obsolete bluetooth/microcontroller module. I also hard wired all the instrumentation inverting inputs to the reference voltage since I only plan to do single-ended...
This RPi 4 computer is not just a compact-sized, Pi 4B based PC, it also offers a complete OOTD experience, apart from the SBC & certain peripherals, we designed, manufactured and pre-assembled everything else. All you have to do is unbox, plug, and...
