This project shows how to use a frypan for surface mount soldering. It uses a thermistor sensor to measure the frypan temperature and a solid state relay to control it. The overall device is controlled by an Arduino. To gain fine control of temperature the relay is controlling the heating element on and off. It’s something like low-frequency Pulse Width Modulation.

This project shows how to build your own LED ring light. “Alan” bought a stereo microscope from ebay and wanted a powerful light source, so he machined one using a lathe. The light ring comprise of SMD LEDs and a block of lexan. He machined it to include slots for the LEDs as well as the microscope mount. Check photos and construction details on the link below.

This project is a very small virtual rotating led beacon build using 4 x 0603 SMD LEDs and it takes place of about 2,5 mm3. LEDs are controlled by a PIC12F629 and drives each led by a PWM signal. See the virtual rotating effect on the video above.

This video shows an ultra fast and precise robot positioning small units. This is used to position surface mount components on printed circuit boards (SMD on PCB) during manufacture. Video was captured at the Japanese competitive robotics event, RoboCup, in Osaka 2010

An intervalometer is used to take a photo at a preset interval. This design by Udi Tirosh may be the smallest DIY intervalometer ever made. It uses a micro PIC microcontroller and two other smd parts and is so small it fits inside a phone jack! Source code and desing files are available on the link below. [via]

This circular board has 12 LEDs animated by a microcontroller. Assembly and HEX code and EAGLE files are provided on the web page.
This project uses the Simple LED Animation Kit (SLAK post or page) with the LEDs arranged in a circle around the PIC16F628A. I decided to do this project after picking up some red SMD LEDs at HSC in Santa Clara, CA, last week. Although the only difference from the basic SLAK is the board design, I find that this layout to be have the potential to be more useful. It could easily be a medallion on a necklace. If I had blue LEDs this would go well in an IronMan Reactor Core package.
This board only needs 4.5V and in the video is running on only 3 AA batteries. You can see that the PIC is still in a socket.
If anyone is interested, I can easily change the SMD parts to thru-hole parts and post an updated board. [via]

With the advent of high-output, relatively-inexpensive white LEDs, it is possible for a hobbyist to make a miniature solid-state ring light with surface-mount technology. The LED ring light featured in this article costs about $10 in parts (PCB, LEDs, resistors, wire, and solder). If you’ve never tried soldering surface-mount parts, this is an excellent project to start with. [via]
