How to make the best DIY back probes in 2 minutes.

Here is how I make back probes for electrical testing.
I use .56mm Guitar string cut at 1.5 inches
Non insulated butt connectors
Shrink tube
and alligator clips.
Here is a link to the Alligator clips used in this video, it is a 10 piece kit that we will cut in half to make up to 20 backprobes. - amzn.to/3wcLBcx
Non insulated butt connectors - amzn.to/3IYlp8G

Good video, only advice i could give is solder the wires on the alligator clips, when you pul the boot back they are just loosely crimped, this could give you a false connection. Solder the wires on the end's for best connection.

Thats a great point Jason, im sure my crimps are strong, but if these have a weak point, it will be the factory alligator crimps. ✌️

[@JasonsLabVideos]

@@Finding_Our_Way thats what i'm saying, your crimps are bang on, but the factory crimps on the Alligators are very BAD! :)

[@f-puppet4059]

Thank you so much! I will be ordering the supplies this weekend to make my set!!!

[@Rein_Ciarfella]

Thanks! Made a set yesterday following your instructions. 👍🔧

[@Finding_Our_Way]

Thats awesome! Thanks for checking it out. 👍

[@kenpryor4440]

I made the same ones a few yrs ago but i used paperclips for the probe still have them and use them today

[@Finding_Our_Way]

Good idea

[@dannywilsher4165]

Great tip. I have a bunch of these clips. I will be making me some probes like yours. I've always used a test light to probe connections but this will be much better!!! Thanks, I subbed...

[@Finding_Our_Way]

Thanks for the comment and sub Danny! Yes these work great.

[@azjackal]

Very well noted.
Thx

[@doc_sav]

This is great!

[@Finding_Our_Way]

Thanks!

[@train4905]

Awsome😊

[@jf3232]

wow this is great

[@Finding_Our_Way]

Thanks😊

[@jrc2905]

I like the idea. they seem like there would be more flexibility. My probes some time bend over from the weight. I looked for some .56 guitar string online but did not see any. Maybe a plain steel paper clip?

[@Finding_Our_Way]

Thanks, yes they work great. I think a paperclip would break pretty easily. These guitar strings handle a lot of abuse. My first set I made lasted about a decade, i only made a new set because i lost most of them. Try walking into a guitar shop, they will have lots of string, thats what i did a long time ago and it was very cheap. Cheers.

[@mnewln1800]

Sweet! Thank you!!

[@Finding_Our_Way]

Your welcome 😁✌️

[@DJ-tn7vj]

Solid DIY video bro. Keep it up. I would have include some banana jacks to go directly onto the probes for your scope as well

[@Finding_Our_Way]

Thank you ✌️. And yes banana jacks are a good idea. 👍

[@thebigpicture2032]

Excellent if you have the materials on hand, otherwise sourcing everything is more expensive than just buying them. At least where I live.

[@alefauman2293]

Can you provide a link to the "non insulated butt connectors" and the shrink tube? (which size do you use for these?) The 0.56 mm guitar string I've found🎸

[@Finding_Our_Way]

Hi, thanks for the comment. The alligator clips i posted are 22-AWG, so amzn.to/3IYlp8G these butt connectors should work (22-16 gauge)
And here is a link for an assortment of heat shrink tubes. Definitely handy to have in your toolbox.amzn.to/43O5CTx
Honestly, I purchased my butt connectors and heat shrink from the local auto parts store, Lordco. And it is cheaper for me there. At lordco i buy heat shrink tube in 3 foot lengths and its very cheap. Cheers

👍👍

[@guateque1718]

Noice,!!!!!

[@ambientsounds1416]

Or instead of buying guitar strings, I will just buy the probes 😂😂😂

[@Finding_Our_Way]

Hmmm, yes that may work 🤔

[@baukesikma9374]

They sell seemless barrel connectors, much nicer crimp

[@Finding_Our_Way]

Good point, those would work better.

[@billsmith2212]

Those test leads are available from Harbor Freight . 5 Colors , 18" for $ 3.59 . Great idea . Jeff Bezos has enough business .

[@Finding_Our_Way]

Nice! I am Jelly of Harbor Freight prices. We dont have that in Canada. The Harbor Freight toolboxes look legit.

[@vicpetrishak7705]

Yes , but Amazon sells a lot of American Products . Garbage freight sell only MADE in China or Taiwan products , their company is not LOYAL TO AMERICA at all !!!!!!!!!!!

[@t1d100]

Nice probes. I have to admit that I am not familiar with the term "back probe." I see that you are plugging them into a connector, but please explain their specific use. Here's a tip... You are using plain steel guitar strings. Plain steel is not the greatest conductor. Guitar strings also come in brass and bronze, IIRC. So, maybe research which of those metals is the better conductor and buy that type of guitar string. HTH.

[@Finding_Our_Way]

Thanks for the tip.
I use these when i need to probe the back side of a connector while it is still plugged in, also if i need to unplug a connector and test the front side it is great too.
The guitar string has a good amount of rigidity, i can press these pretty hard and the guitar string doesnt bend.
I use these when diagnosing vehicle electrical components.

[@hullinstruments]

Same here.... I work with test equipment and metrology but had never heard the term. Interesting video and premise. I could see them being really useful in your position
Thanks for sharing!

[@gordselectronicshobby3853]

Not a good idea at all. They won't last.

[@Finding_Our_Way]

My first set lasted about 6 years, i work full time in auto repair and these get used regularly.
