Building an EDS LeakSeeker 89!

The EDS LeakSeeker is a unique device for finding shorts. Watch the videos on YouTube by EDS or check the description on the EDS website. Unfortunately, EDS stopped selling them a few years ago. But there is a way to build one yourself!

During a routine search after a used LeakSeekers (which don't exist, everybody is keeping them!), I came across THIS PAGE.

I wrote a mail to Dave Miga of EDS, who designed this cool device, and after he had confirmed that shipping to Germany is possible, I ordered a board from the above source and a parts kit from Dave.

This wasn't exactly cheap, but this thing is so unique and useful that I just had to build it! I will enjoy it until the end of my days as I don't think that anybody will design something similar anytime soon.

And here it is, the assembled LeakSeeker on my bench in a prototype stage. I have yet to find a nice case for it. The original case has no space for 9V battery blocks. I like portable testing tools. The thingy draws less than 100mA when it is testing and 30mA idle.


It is not difficult to build, yet there are two things I (almost) messed up:
  • Make sure that the resistors left to the gain switch are all the way in, otherwise, they might short with the metal case of the switch.
  • Handle the 0.05 ohms wire carefully and don't bend its legs. The legs are welded to the wire and can break off.
During my first tests, I thought it didn't work because it can take quite a while until it moves from the green LEDs to the yellow and produces a deeper chirping sound.

Here I am playing around with a testboard that has a 10 Ohms resistor to simulate a defect component. The sensitivity of the LeakSeeker is astounding. I can hear the tonal difference of 1cm distance on a trace in the low gain setting.


Update 2024: Finally a Home for the LeakSeeker

After a whopping four years, I finally got around and built a case for the LeakSeeker. While browsing through my drawers I also found a long-forgotten 2x9V battery compartment, which fits perfectly.
With a slide switch, I can choose the power source. Cool, now it's a no-fuss portable testing device.









This is the answer I got from Dave to my inquiry. I think he won't mind me showing it here.

All EDS products use pc boards fabricated by andy.yu@fastechcircuit.com 
These pcb makers will have a small minimum of boards that must be made so there will be extras;
There are also many people selling these extra spare pc boards on eBay; do a Google search or see email list below.
Or anyone advertising in magazines like Elektor or Nuts and Volts. Or get spare boards from other kit builders. Try these, most have purchased parts kits and may have spares...

  1. I know you say no commercial sites but I'm hoping you allow this since you link to my blog and outdated eBay listing above and I want to share the current sources for parts.

    I've still got the bare PCBs, enclosures, and panel overlays available on eBay as well as my website (https://store.eccentricworkshop.com/index.php?main_page=index&cPath=14_15). I don't yet stock the parts kits but buyers can have Dave at EDS, Inc ship them to me and I'll package everything together to save on international shipping (usually $15-20 rather than $50).

    Thanks for buying a PCB and showing off your build!

    3. Hola, como Estas?, Hey hay dos sitios de internet donde ouedes compare El kit completo del EDS 89 Leakseeker y ensamblarlo tu mismo o alguien mas, y cuesta alrededor de $200.00 dlls. No se si hacen envious a Colombia.

  4. Thank You for the information and the warnings. I just bought this kit and was wondering about how to properly install the 0.5 ohm resistor? I see that the part is too wide to place in the holes properly. You noted not to re-bend the leads because the leads are welded and may break off, So if you leave the part as it is and mounted it on the board the resistor will be too tall to mount in the case. Would you have a picture from the side view? Did you press the part down from the top and flatten it?

    1. I did bend mine, however not at the welded legs, but the actual resistor metal stripe. It sits as low as possible. I don't have a case for the device so far, so can't tell it that works.

    2. Thank You for your response. I think I will try to bend my resistor (R2) to the same height as the 5 Watt resistor (R14) right beside it. The board should fit (hopefully) in the case.
