Solar Charge Controller Kit 2.0 Geiger Counter Kit
Wireless Freezer Alarm
Now you can record your own
shaking, rattling, and rolling.
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.

3D LED Cube Kit
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.

With one PCB you have the option
of detecting wirelessly:
temperature, vibration, light, sound,
motion, normally open switch, normally
closed switch, any varying resistor
input, voltage input, mA input, and tilt,
just to name a few.
If you charge batteries using solar
panels, then you can't afford not to have
them protected from over-charging. This
12 volt/12 amp charge controller
is great protection for the money. It is
simple to build, ideal for the novice, and
no special tools are needed other than
a soldering iron and a 9/64" drill!
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 LND 712 tube in our kit is capable
of measuring alpha, beta, and
Partial kits also available.
