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.

Now back in the NV Webstore — the
new and improved Talking Skull Kit.
The new kit includes the much improved
audio/servo driver board. See all the
details online. This kit provides all the
necessary supplies to build one talking
skull. You provide the labor and tools, and
you’ll have a great Halloween prop
in no time!
The fading eyes circuit gives you two LED
eyes that can be adjusted between a slow
fade-in/fade-out to quick pulses. The speed
is changed by simply adjusting the variable
resistor with a small screwdriver. Another
adjustment allows you to set how long the
LED stays on within the on/off fade cycle.
Includes a battery snap, two red LEDs, and
two 24 inch eye cables.

no special tools are needed other than
a soldering iron and a 9/64" drill!

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.
Partial kits also available.
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.
