Handy 20 Drill Bit Set for PC Boards
Handy drill bit set contains 20
different steel drill bits from size
61(.039”) down to 80(.0135”).
You can use these if you are
careful with a hand held hobby
tool to drill the holes in PC
boards (unlike tungsten carbide
bits that break instantly if not used in a drill press). Of course
tungsten carbide is sharper and harder than these, however
we find these tiny steel bits to be great for drilling PC boards
when you don’t have access to a drill press. Comes in a
small metal box inside of cardboard packaging which will
have stains on it (drill bits are coated with oil for protection).
G17294

Ultra Thin Cell Phone Microphone
These
tiny
microphones
type
ERBSXK1079654 were made for use
in cell phones. They have a special
conductive elastometer connector in
the easy to peel off rubber boot. When
you peel off the boot two tiny gold
plated surfaces are exposed which it
appears you could easily solder to. We have no data on
these, however, they are brand new and are probably the
smallest microphone we have ever seen. Size 0.23” Dia x
0.06” Thick.

Battery Operated High Voltage Generator
This high voltage
generator PC board
packs a whallop. It
operates from 3VDC
at 120mA (battery
power) and charges a 0.015µF 2KV capacitor to about
2000VDC in an instant. It was made for a portable bug zapper!
When you short across the leads connected to the capacitor
you hear a pop and create a spark. Looks like it would be
great for use in all kinds of high voltage applications. Size
about 2.4”L x 1.2”W x 0.75”H. We have no data, schematics,
etc, we just know that you connect (+) 3VDC to the white
lead near the transformer and (–) to the green lead. Board
has been coated with a high voltage insulation coating. You
should not buy this unless you are familiar with working with
high voltages and you should be careful to take all safety
precautions when using this board. Removed from new bug
zappers but sold “AS IS” only.

Made by Motorola, these were made to measure
pressure ranges that you would find in medical
devices (up to 300mm Hg). We are not sure of
the exact pressure range spec on this one but it is
similar to the MPX2011DT1 or MPX2301DT1 sensors. They
all have the same hookup. These are based on piezoresistive
technology. The case is the white plastic chip PAK and is only
.38”Tall x .26”W x .10”Thick. Has small fitting with a black
colored gel inside for mounting to your hose. The size of this
fitting is .123”Dia. The sensor is brand new on tape and reel.

115VAC 1Amp
Adjustable Timer Module
Nifty timer module is fully adjustable with on
times from 75 seconds up to 4 hours. This
heavy duty module is 1” square x 0.08”H and is the same
type found in many industrial machines, washers, dryers,

load up to 1Amp (115Watts) to it. To start the timing process,
you press the momentary pushbutton, the load is energized
for whatever time you have set with the potentiometer. At the
end of the time the module turns off the load. New, made by
