Default Cap Foil Side Tester

Hi,

Has anyone made Mr. Carlson SIFT foil side cap tester? Any thoughts?

Iíve watched all the videos so I decided to make one because it doesnít seem like thereís any product on that market that does this. Iím at the point where I ordered all the components and am waiting for them to come in.

Any thoughts on making one of these?

Thanks

But it requires a sign-up. Maybe if you post on the patreon site you may get a response from someone who has made one.

Now that you got sucked in, you should pay the piper. Can you just
do it by the project, if that is what you want to do.


No sense doing the monthly thing unless you know what else is available?
If so, join for a month and download everything from the site.


If you like the stuff be happy share with those you care to or not.
I'm sure some of the stuff is already in the public domain, as
expired patents etc.



Cheers,

If you insist, you can always come up with your own. I am pretty sure that there is 0% rocket science involved, just 1970s tech (essentially, an audio amplifier with high impedance input to amplify the hum, a rectifier, and LM3915 or similar bar graph driver - the trickiest part may be reversing the cap and providing an indication without having to resort to an unduly exotic switch). You are merely paying for the convenience of getting a project with all the nitty gritty already figured out, instead of having to making it work well by yourself, which may be a more than fair tradeoff depending on how much you value your time.

Mr. Carlson shows how to test for the foil side of a capacitor using only an oscilloscope and a BNC-to-alligator-clips test lead like this one

Yes that device he is using with the oscilloscope in this video is the switching portion of of the complete SIFT device he made later with the led display to replace the oscilloscope. The complete device schematics is available on Patreon only.

I have paid for his Patreon for a year or so now. I enjoy his videos and projects, and the two dollars a month is well worth it for me to build a project with all of the bugs worked out.

The only thing I did differently is I modeled the PCB in a CAD program as to get the PCBís made professionally rather than etching my own. Theyíre due in today. Iím doing the complete unit so I donít have to use my oscilloscope.

Thanks

I'm a MCL Patreon subscriber. Any chance you might have an extra board to sell or the gerber files? I've been thinking about drawing up his PCBs to get boards made for this and for his low voltage capacitor tester.

Hi,

I just finished my SIFT unit. And it works very well. I’ll post a couple pics of my build later.

I do have several more boards. PM me.

I’ll be doing boards for the leakage tester next.

Thanks
