My project mod ebay frequency counter

My project mod ebay frequency counter

i Build a 5 volt power supply
Based on LT1764
I added a BNC connector
CONN BNC RCPT STR 50 OHM SOLDER


And coax cable

TE CONNECTIVITY - RAYCHEM
5019D3618-9
TE Connectivity Aerospace, Defense and Marine

and Aluminum Case
Which I specially adapted
For him

Works pretty well
In addition I built
A small oscillator tester
I'll add to him a BNC connector later on

i add 9v voltage reg LM2940 to the oscillator tester

Good job Daaz.
I've bought this counter last year (very cheap on Ebay), but unfortunately it is not able to measure frequency below about 100kHz. I only read the bid too fast.
Anyway, it work fine (and precisely) above.

I can measure it with frequencies starting at 200 Hz
Enter the menu
Filter - Select Off
And select L mode (Low)
If you are in A mode ( Auto)
It measures from 100 kHz

I tried to switch off the filter too, but i don't remember to be able to measure
as low as 200Hz. I will try again then !

I am now building an aluminum chassis
For the
Colpitts Crystal oscillator tester

That I built

I cut the aluminum
For the chassis.

I dril holes for the LED
And the BNC.

I painted
In a blue candy.
4 layers In the oven 50 degrees.

Almost ready
All that remains is to add the led
And connects to the power adapter

 

[dazzz]

Almost ready.
I finally used my glass cutter for a purpose that not jast artistic

Mission completed

i Pierced holes the For screws
It's ready at last
