IntroductionVaporization is done by off-the-shelf ultrasonic atomizers, either really cheap ones (the black ones in the picture below, 2.50 $ each) or some more rigid ones (the silver one, a Fogstar 300, 290 € each), air is moved by an array of...
The idea behind this project was for my sons birthday party. He wanted a robot themed party, so I figured this would be the easiest to build. Similar to the commercial claw machines, the idea is to grab a toy and successfully get it transferred over...
The local club needed another scoring box, and the things cost a fortune. So naturally I thought, "Hey, I can totally build one of those!". And I did, sort of.First attempt was way too elaborate. it was a whole enclosure with EL panels...
To synthesize nice sounding musical notes you need to control spectral content of the note, the rise time (attack), fall time (decay), and the change in spectral content during attack and decay. Also it is nice to have at least two independent musical...
The device is based on a PIC16F88 microcontroller. The sleep mode of the PIC is used for standby, negating the need for a power switch. The PIC simply records the last state of the metal ball switch and then uses the opposite of this as a trigger for...
QUUB is an open-source, micro controller system based on a core processor, addressable daughter boards, and remote IO modules. It is a general-purpose embedded microprocessor system, the form factor is based on a main MCU board and multiple stacked...
Features Supports 3/4 lane MIPI DSI displays.DSI controller supports resolutions of up to 1080x1920 at 60 Hz refresh rate.Converts HDMI video to DSI - letting you connect any MIPI DSI screen to your PC, Raspi or similar devices. Conversion works up to...
First you need to mark out a suitable area on the back of the guitar for the battery compartment measure it's dimensions in height and width. There's always a lip on battery boxes to cover the router cut on the guitar body so measure the inside dimension...
Simulated visual systemWe want to use artificial neural systems to teach biological instrumentation methods. The goal is a set of small circuits which behave like neural systems with respect to voltage, timing, and system behavior. This will enable...

Opamp circuits:Repressilator: The repressilator is a genetic oscillator (3). Here we build an electronic approximation of the repressilator. Gene expression is represented by the output of opamps U2, U3 and U5 below. Protein concentration is represented...
Making GSM phone utilizing GSM modules is not that complicated. One needs to use MCU with UART and few IO lines and then truckload of patience for writing decent parser of AT commands - that can be nightmare to do correctly. For this construction, I...
Soft oscilloscope This program:Simulates the function and appearance of a traditional two-channel oscilloscope. The GUI consists of a simulated oscilloscope, hereafter refered to as the scope. Accepts real input from either the Windows sound device,...
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...
Joe made an excellent write up and created some great sample code to go along with the NeoPixel shield. This was helpful because most of the examples in the code provided by Adafruit were geared for NeoPixels in general, this one however was built with...
