Invention of the day: The banaligator
« on: November 07, 2024, 12:04:28 pm »
Tadaaam!!!  Proudly presenting ... [drumroll] ...  The Banaligator!  8)



Take a thick paperclip, cut in two places to get 3 pieces of U shaped paperclip wire of different heights.


Solder those inside the tail of an alligator clip, to form a 4mm banana plug.


Found it to be very practical when attaching unterminated wires to the power supply.

If you unscrew the binding post a little bit there is already hole to put a wire in on all of my TE with binding posts.  ;)
I told my friends I could teach them to be funny, but they all just laughed at me.

Yes, but the banaligator would be faster and easier at attaching wires.

Side note, the binding posts in the Rigol DP832 power supply I have are notoriously bad.
https://www.eevblog.com/forum/testgear/wires-connected-without-banana-to-binding-posts-(rigol-dp832-power-supply)/msg5700041/#msg5700041  So far I had to use them only with banana terminated wires (even so, the banana hole in the red binding posts is smaller, some banana plug brands do not fit in the binding posts for plus, but they fit in the binding posts for minus  >:()

Except this time I've run out of bananas, tried to DIY a few more, and that's how I've accidentally arived to solder pieces of paperclip wires on an alligator.  The intent was to cut away the alligator jaws and solder a wire instead, only to realize it would be easier to leave it just like that, a banana with jaws.  ;D

It would also likely be faster at blowing fuses and/or output stages too.

You should just buck up and fix your power supply before you get hurt having dodgy interconnects everywhere

https://www.digikey.com/en/products/detail/pomona-electronics/3760-3/736552

a few DIY special use adapters is one thing, but they should not be sticking out of your power supply in force

Wago are way ahead of you

https://uk.farnell.com/wago/51174966/plug-4mm-cage-clamp-red-pk5/dp/1283539

(Attachment Link)

Some action photos.
They work well with quite thin wires too, very handy when quickly trying things out.
I'm not using many (any) red/black in the photo because those are frequently sold out.

I also like the Deltron banana plugs (553 series) because they are about the cheapest reasonable quality plugs around for general use. Unless I need something higher-performance, I use those because they are extremely low-cost, have a screw terminal (so can even be easily reused at a pinch) and support stacking.

Similar-ish functionality ones are already there.
They don't look all that great, though! (Although, to be fair, even the Wago ones visually look flimsy, but they perform fine.)

I prefer the Wago banana-end style over that AliExpress one, however (i.e., convex-bent steel wire in the shaft).

this is an old concept I am sure people soldered speaker terminals to a banana connector before for convenience. I almost did many years ago but my speaker terminal was very low quality meant for super shitty panel mounting, long before 3d printers were popular

I didn't think of that before, but it's a good point. The lever terminal on the banana plug is really not much different to the ones that were on the back of audio amps.

maybe no one ever did it because when you take that apart you really doubt that its a good idea when you see the actual part :D

Usually you think "I can't believe that works" and "I can't believe they sold that" and "I can't believe I bought that"

A wiring spring, like those in old electronics kits

It is basically a static structure at that point without any lever, pin or other mechanical jibba jabba that can cause problems. The alligator clip is a complex machine in comparison.

If soldered to a banana connector or shaped to be compatible with one it should make for a easy wire interconnect.




I think rogeorge can do better then make over complicated adapters


I believe the paper clip by itself can make a good interconnect so long its plated, shaped and tempered properly in the right places

Such a creative solution, RoGeorge! The banaligator seems super handy for quick setups. It’s impressive how a little ingenuity can solve everyday challenges. Just curious, have you tested its long-term durability?

Thank you.

Not tested, only found that combination a couple of days ago.  Might need an isolation sleeve, too, as it was pointed out (a large shrink tube anchored to the alligator screw would do it).

Meanwhile I was looking for an even simpler way to DIY a banana connector to casual wires.  After all, alligators and bananas are middle-man pieces of metal.  Would be better to connect the strands of the wire directly to the binding post.  The sideways hole at the bottom of the binding post is one way to do that, but not very practical.

So I am looking now for methods to DIY a banana out of the copper strands of the wire itself.  The idea is to use a round wedge to press the wires against the inner walls of the 4mm hole inside the binding posts.  Pieces of round wood make a good wedge (tried chopsticks, toothpicks, matches, a twig, etc.).  Maybe not the most elegant, but very firm contact.

Another way would be to use the sleeve from a cable of just the right thickness, and to bend back the strands of the wires, something in the style of second DIY banana from the right:
 


Has to be something made out of common items, dirt cheap, and no longer than a minute to make.

Still looking for other ways to quickly and reliably plug a cable without using a banana.  Has to be something that can accommodate with slightly different diameters of the binding posts holes, too, like the faulty ones in my DP832.  Not sure which model will win in the long term.

I have two pairs of spring loaded banana connectors for quick wiring. This wago copycat looks interesting though, and I haven't seen it before thanks for posting.

As an aside: am I the only one that parses the term intuitively as banal-igator?  Perhaps it is just my ugly personality, though.

A therapist is not someone who has non-consensual sex with your mind, though.  Pity "mind blown!" is off by one base.

I particularly like therapistfinder.com: I know it is just two words, but I always see three.
