Microchip Technology's MCP9804 Temperature Sensor provides high temperature accuracy of +0.25° C (typical) and +/- 1° C from -40 to +125°C, as well as static current consumption of just 200 µA (typ.). Available in small 8-pin MSOP and 2 mm x 3 mm DFN packages, the I2C™ device reduces board space and enables longer battery life for industrial, automotive and consumer applications.
Every one of these first gen timelapsers was a labor of love, taking countless hours to complete. They were deployed by the dozens. The alarm clock buzzer is wired to an optoisolator which lets the tiny current activate an input to the ATOM microcontroller. The chip turns on a relay to turn off the alarm and reset for the next day then another relay shorts across the cameras power switch, it waits for powerup then another relay shorts across the shutter button contacts. After another short delay, the cam power relay turns it off to wait for the alarm again
This is the model R/C tank I am designing on a gearbox + Tracks & wheels from Tamiya. The radio is Hitec and two receiver servo outputs feed my microcontroller-based Pulse Position Modulation output into Pulse Width Modulated power output to the two motors.

Assembled AuroraWatchNet magnetometer sensor unit. The lower PCB is a Calunium v2.0 microcontroller board, the upper PCB is the FLC100 shield. This contains a Ciseco XRF radio module (blue PCB). The FLC100 magnetometer is located on a remote PCB (not shown).
The Arduino Duemilanove on a 6mm polycarbonate slab with four non-slip feet. The PCB is supported on M3 threaded spacers, and held down with Allen bolts (which I salvaged from a Video 2000 VCR). The edges of the polycarbonate slab have been polished, using toothpaste.
A small present for my girlfriend.

Lissajous figures are interesting curves that occur in systems where oscillation happens in more than one direction, for example when a pendulum hanging from a string moves in the plane.
These pictures are from an easy persistence of vision approach to playing with Lissajous figures. Read more about this project here.

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced its first instrumentation amplifier, the MCP6N11. The new instrumentation amp features Microchip’s unique mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means to control offset drift, which results in higher accuracy across time and temperature. The MCP6N11’s low-power CMOS process technology enables low power, while providing a gain bandwidth product of 500 kHz, and it features a hardware shutdown pin for even more power savings. The device’s low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, and its rail-to-rail input and output operation enables full-range use, even in low-supply conditions.

A pwb course exercise. I had to lay out a circuit in Orcad, I wanted to try a certain clock generator and I've been thinking of putting some of the 8515's on a board. So I threw something together. Two sided board, plated vias, milled with some machine. Kind of tricky to solder. Larger pads and holes would have been welcome in hindsight.
As the electronics hobbyist one of knowledge that we have to be familiar with is how to make our own printed circuit board (PCB). Making our own simple single side PCB actually is not require a sophisticated technique and technology as you might think, instead most of the required materials is already available at your home.
