Digital Controlled FM Stereo Transmitter
For more than a decade we’ve
been the leader in hobbyist FM radio transmitters. We
told our engineers we wanted a new technology transmitter that would provide
FM100 series quality without the advanced mixer features. They took it as a challenge and designed not one, but TWO transmitters!
The FM30B is designed using through-hole technology and components and is
available only as a do-it-yourself kit with a 25m W output very similar to our FM25
series. Then the engineers redesigned their brand-new design using surface
mount technology (SMT) for a very special factory assembled and tested
FM35BWT version with 1W output for our export only market! All settings can be
changed without taking the cover off! Enter the setup mode from the front panel
and step through the menu to make all of your adjustments. A two line LCD display shows you all the settings! In addition to the LCD display, a front panel LED indicates PLL lock so you know
you are transmitting.
Besides frequency selection, front panel control and display gives you 256 steps of audio volume (left and right
combined) as well as RF output power. A separate balance setting compensates for left/right differences in
audio level. In addition to settings, the LCD display shows you “Quality of Signal” to help you set your levels for
optimum sound quality. And of course, all settings are stored in non-volatile memory for future use! Both the
FM30B and FM35BW T operate on 13. 8 to 16VDC and include a 15VDC plug-in power supply.
(Note: After assembly of this do-it-yourself hobby kit, the user is responsible for complying with all FCC rules & regulations within the US, or any
regulations of their respective governing body. FM35BWT is for export use and can only be shipped to locations outside the continental US or
valid APO/FPO addresses or valid customs brokers for end delivery outside the continental US.)
Electronic Chirping Cricket Sensor
Electronic cricket? Sounds
just like those little black
critters that seem to
come from nowhere
and annoy you with
their chirp-chirp! And
just like the little critters,
we made it sensitive to
temperature so when it gets warmer, it chirps faster!
That’s right, you can even figure out the temperature
by the number of chirps it generates! Just count the
number of chirps over a 15 second interval, add 40,
and you have the temperature in degrees Fahrenheit!
Not as fancy as a digital thermometer but much more
unique! And unlike its little black predecessor, the
ECS1 operates from around 50°F to 90°F! I don’t think
there are too many real crickets chirping away at 90°F!
A unique thermistor circuit drives a few 555 ICs providing a variable chirp that is guaranteed to annoy
everyone around you! But just watch their faces when
you tell them the temperature outside! Runs on 9-
12VDC or a standard 9V battery (not included).
Includes everything shown, including the speaker and
battery clip, to make your cricket project a breeze.
ECS1 Electronic Cricket Sensor Kit $24.95
Electrocardiogram ECG Heart Monitor
Use the ECG1C to astound your physician with your knowledge of ECG/EKG systems. Enjoy learning about the inner workings of the heart while, at the same time, covering the stage-by-stage electronic circuit theory used in the kit to monitor it. The three probe
wire pick-ups allow for easy application and experimentation without the cumbersome harness
normally associated with ECG monitors.
The documentation with the ECG1C covers everything from the circuit description of the kit to the circuit description of the heart! Multiple “beat” indicators include a bright front panel LED that flashes with the actions of the
heart along with an adjustable level audio speaker output that supports both mono and stereo hook-ups. In
addition, a monitor output is provided to connect to any standard oscilloscope to view the traditional style
ECG/EKG waveforms just like you see in a real ER or on one of the medical TV shows! The fully adjustable gain
control on the front panel allows the user to custom tune the differential signal picked up by the probes giving
you a perfect reading and display every time! Additional patches are available in 10-packs. Operates on a standard 9VDC battery (not included) for safe and simple operation. intended for hobbyist usage only. If you experience any cardiac symptoms, seek proper medical help immediately!
ECG1C Electrocardiogram Heart Monitor Kit With Case & Patches $44.95
ECG1WT Electrocardiogram Heart Monitor, Factory Assembled & Tested $89.95
ECGP10 Electrocardiogram Re-Usable Probe Patches, 10-Pack $4.95
The kit has a pulsing 80 volt tickle
output and a mischievous blinking LED. And who can resist a
