The Poor Man's Seismograph is a great
project /device to record any movement in
an area where you normally shouldn't have
any. The kit includes everything needed to
build the seismograph. All you need is your
PC, SD card, and to download the free
software to view the seismic event graph.

This kit shows you how to build a
really cool 3D cube with a 4 x 4 x 4
monochromatic LED matrix which has a
total of 64 LEDs. The preprogrammed
microcontroller that includes 29 patterns
that will automatically play with a runtime
of approximately 6-1/2 minutes.
Colors available: Green, Red, Yellow & Blue

This is an inexpensive surface-mount
project that is good for beginners to start
with. This kit has its own printed circuit
board (PCB) which makes mounting the
components easy. Plus, it comes in a pocket
size shielded aluminum case measuring 3. 5"
in length and 1" in diameter. The on-off
switch is a pushbutton on the bottom.

This kit is a great project for high
school and university students.
The unit detects and displays levels of
radiation, and can detect and display
dosage levels as low as one
micro-roentgen/hr. The LND712 tube
in our kit is capable of measuring
alpha, beta, and gamma particles.

FOR BEGINNER GEEKS!
The labs in this series — from GSS Tech Ed — show simple and interesting experiments and lessons, all done on a solderless circuit board.
As you do each experiment, you learn how basic components work in a circuit, and continue to build your arsenal
of knowledge with each successive experiment.
