“This project has been an astonishing little journey. Many of my previous projects were characterized by an amazing outpouring of effort to build something highly intricate and ultimately invisible…A little bit of work and a little custom design to create something new and exciting that I can immediately use in my everyday life. It also happens to be a sex toy.
In other words, I wanted to hack something I actually use: my vagina.”

“Pretty much every time I tried to work with some sort of digital interface I run into some kind of trouble where a logic analyzer would have saved me hours of blind debugging and posting to various forums….It was the first time I worked with SPI on a pic32 and as expected nothing worked for the first try.”

“Well, living together with a person comes with some responsibilities that are to be tackled. Like watering plants. My friend I’m sharing an apartment with was leaving for a couple of weeks and has burdened me with a task to take care of several pots with alien life forms.”

“Inductors are not the most popular parts in constructions.
The bad reputation comes from the lack of good measuring tools.
This project will explain how to build a very accurate and simple inductance, and capacitance measuring tool. ”

“Using a arduino and some resistor to work as a 8bit DAC, so we can make some waveform form it , build a Arduino simple signal generator. what you need just a Arduino, a protoshild and some resistor.”

“This mini Logic analyzer is a tool for you to watch on LCD the logic transitions 0 or 1 of a digital data signal. A digital data signal can be found on the output pin of TSOP-1730 Infrared Receiver, on the Transmit and reveive pins of MAX-232 chip (RS-232), on Clock and Data pins of I2C data bus and many more electronic components. This circuit supports capturing for up to 100 kHz digital signals.”

“I’ve recently had success in making a conductive ink using a fine copper powder suspended in an acrylic airbrush medium. This paper on conductive epoxies was really the key to getting this ink working….There is still quite a bit of experimentation to be done, but this is a very encouraging result!”

“This I2C-bus analyzer capture all transmissions via I2C/TWI bus, decode it and send to PC via virtual RS-232 port. Received data can be displayed by any terminal program on PC computer. Main part of analyzer is ATTiny2313 microcontroller with 20MHz crystal. Link to PC are realized by FTDI FT245RL on UM245R module.”

“This is a project that I made to take care of an ever increasing need to prototype vacuum tube (valve) circuits. As you can see from the photos, it really is a test “board”. I do a lot of work with tubes and love to design and improve circuits.”
