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 $5.00/set. 

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. 

G17276 $1.29 ea. 

Heavy Duty Brushed Aluminum Handle 

Attractive heavy duty brushed aluminum handle 

come complete with mounting bolts. These 

mount to panel holes spaced 4.5” apart. Height 

above the panel about 1.15”. Brand new nicely made 

with threaded holes for included bolts. 

G17312 $2.49 ea. 

Deluxe Prototype PC Board 

Deluxe glass epoxy prototype PC board is 

much sturdier than the phenolic boards we 

sell. This one is 2.5” x 3.5” x 0.06”Thick. 

It has 600 holes each surrounded by a 

copper pad. Makes prototyping small 

circuits more reliable and professional. 

Holes are on 0.10” centers to simplify component mounting. 

High quality at a blowout price. 

G17131 $3.50 ea. 

Deluxe IC Prototype PC Board 

Deluxe glass epoxy prototype PC board 

is much sturdier than the phenolic 

boards we sell. This one is 2.5” x 

3.5” x 0.06”Thick. It has 460 holes for 

components and 72 holes for mounting 

8 pin, 10 pin and up to 20 pin ICs. 

This one is very handy for almost all 

prototyping needs. Makes prototyping IC circuits a snap. 

Holes are on 0.10” centers to simplify component mounting. 

High quality at a blow out price! 

G17129 $3.75 ea. 

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. 

G17350 $4.98 ea. 

High Quality 8” Hemostat 

High quality stainless steel hemostat/ 

forceps made in Pakistan. These are 

very nice 8” long straight hemostats 

that you can lock onto a wire, part, 

fiber, etc. Great for all types of hobby 

applications. New!
