Photos from our craft room. This is a dump of photos from my phone. Many may be duplicates or similar angles.
My first look at the circuitry of the YN-460 flash.
This is the inverter board that drives the flash tube.
BTW thanks TC. for being the first to risk it!
PS see this discussion for more info
This is an laser cut enclosure for mobile arduino prototyping. I will start selling this soon. A bit more testing is needed.
Check:
Physical loopback: USB to serial. On the left of the screen is the USB port, where I'm catting a big file into /dev/ttyUSB0; on the right side of the screen is picocom, receiving the file off /dev/ttyS0. To the left of the computer you can see the silver USB cord, going to a bog-standard FTDI232 translator board, then through a Dallas DS275 ttl-to-RS232 voltage converter, and then through the rainbow-colored cabling to the serial port. This is a proof-of-concept version of the front end of an Arduino, allowing me to do tiny embedded Arduino boards consisting of just the processor and clock circuitry, while still using the Arduino software interface framework.

Ingredient for a simple target board: Perfboard, 6-pin DIP header, optional battery box, and two types of 20-pin socket: low cost and zero insertion force.

This is a picture of an Arduino controlling a 12V DC fan through a TIP120 transistor. Note that this is not the same as IRF520 transistor below. The pinouts are different.
An Arduino being used to measure the speed of a 12V computer fan. An IR light emitter and photodetector are placed on either side of the fan. As the fan blades spin, they break the beam of light coming from the IR emitter from being seen by the detector. By counting how often this happens, we can figure out how fast the fan is spinning. In this picture, the LCD display says the fan is spinning at approximately 5040 RPM. This was programmed in C++.
This project was interesting because it is a very direct way to see how fast computers really are. The fan is spinning so fast that it just looks like a blur to the human eye, but even this tiny, not-so-powerful microcontroller had no problem keeping up with it and counting the rotations. Very cool.

Microchip announced a new series within its high-performance PIC32MZ family of 32-bit microcontrollers (MCUs) that features an integrated hardware floating point unit (FPU) for high performance and lower latency in intensive single and double-precision math applications. This new 48-member PIC32MZ EF series also offers a 12-bit, 18 MSPS analog-to-digital converter (ADC) for a wide array of high-speed, wide-bandwidth applications. Additionally, the PIC32MZ EF supports an extensive DSP instruction set. This combination of DSP instructions, a double-precision FPU and a high-speed ADC improves code density, decreases latency and accelerates performance in process-intensive applications. For an overview of the PIC32MZ family, please visit: www.microchip.com/PIC32MZ-091415a
The latest Microchip TCP/IP Stack, downloadable from www.microchip.com/tcpip, includes an SSL module, which enables secure, encrypted communications between two nodes on an unsecured network. It supports both client and server functionality, while providing fast 128-bit ARCFOUR encryption for bulk data transfers.
