Can you tell me what display that is? I have an extra T7 that is broken and I wanted to use the display for another project, but it has no markings on it. I know it's a 160x128 TFT, but I'm looking to find the pin info to use it with an Arduino. Thanks.
Hi Paul, this is Paul. I changed out for a 2400 mAh battery and had to remove the white 2P connector to make it fit. Later I found out some complex mosfet style components could make the unit freeze (stumped?) with the display stuck on and not shut off. So I had to add a switch so that it would not require disassembly and soldering each time. I suppose I could also let the cell drop until the unit doesn't get enough voltage, inconvenient though. Added a slide switch, similar to what you did, slightly different place and method but same result for a different reason. I am sure others will find your post helpful. I will give you a thumbs up just because!
I'm sorry Paul, but I couldn't help laughing when you managed to carefully dump the load of Baking Soda on the switch. I was waiting for you to glue the plate to the table ! This one was very ... educational ... 🤭😁🤣 eeerrr I assumed you used Solderstick to splice the wire. 😄
Sir, thank you for making this video! Not only does it give me the idea about putting a switch in my component tester, but it also provides a video that I can watch when things are going terribly wrong and my self-worth has become nonexistent!!! It helps that even a MASTER like yourself can have a bad day! Everything will work out in the end!!! Otherwise, a few blows with a 5 lb sledge, and a broom removes all traces!!! THANK YOU!
I have a couple of older versions of this tester that are powered by 9v PP3 battery. I fitted a 3.5mm jack socket to both & just power it from a USB to 9V cable
Modded a regular multimeter, brought out a power lead, made 2 posts for the meter, and a pushbutton switch in between when pushed while holding a resistor to the posts, it activates and shows the resistor value.
One thing you did not consider is calibration. Every time you turn off that switch it looses calibration and reverts to defaults. To calibrate connect 1, 2, and 3 together with short wires and hit test.
You should always have a Dremel on the bench. I've found them very handy with all their functions. Have the right size of switch that would fit and JB Weld or Epoxy would have been better and know how much wire you'll need.
I would have used the first switch but soldered it on a small pcb. Solder the battery to the switch contacts and the pcb to the upper panel. That give good electrical connection and strong mechanical resistance. And always look and measure 3 times before cutting once ;)
It's a good idea installing a switch, but I think the switch has to be on the connected position for the unit to charge up. Is there any other way to install a switch?
I wonder if yours has a fauly battery ? I've had mine for about 2 years, I charged it once when I got it and rarely used it since. (My health got worse and I've had to quit electronics after 40+ years). It's still at 50% power.
I would have spent 3 hours walking around wondering why I have a hot soldering iron superglued to my fingers, and why my hemiparuplegic wife was firefighting.

Old modeling trick to hide seam cracks. I use baking power but either works. When dry just sand and the crack is all gone. Primer and paint. All gone. Lol I was hoping you remembered the circuit board, Oops... It happens to me all the time... Lol LLAP 🖖
The super glue and small switch is not very compatible I already destroy many small switch on that so just change and use epoxy but super glue is still the best glue for my projects
I agree. Keep in mind that cyanoacrylate (super glue) is volatile and can migrate into the switch connections, thus causing coatings on the connectors. In criminal forensics the CA is used in the vapor form to distinguish fingerprints. Forgot the CA instead use epoxy.

You gotta love when what should be a simple job turns out to be the opposite! The story of my life Paul, Murphy's law! Great video sir!

I own the 9v version of this and plan on doing something similar. Love the feature set, hate the randomly dead batteries when I need to use it.

14:58 Barking Spiders? I have to win a prize for catching that.
We all have those days were everything fights you. Thanks for posting that it is not just me.
What's the difference between the T1, T2, and T7 versions? The T3 version has a built in o-scope and signal generator.

I was wondering this too. The main reason I need a switch is for reset purposes when the machine locks up identifying a complex semiconductor.

Even 4 or 5 times ... ;)

Good idea. Will have todo it to mine.
Went better than if I had done it!!

Sent you info for a slim rocker switch. Thanks for the reply.
I also rep.aced the chinsy battery with an old cellphone battery - it stays charged a lot longer now
Why didn't you used US dollar note to apply the Baking Soda？ 🤣😂

JB weld would work better than CA/baking soda in this case. Does not set as fast, but won’t glue everything in a 5 mile radius.
Dremel to the rescue!
Thanks mate!
😑 Glad I am not the only one that does stuff like that. I always say plan ahead, yea sounds good.

I have to agree that is a needed modification. Every time I go to use mine the thing is dead.
Yep, I've put a switch in mine too.
Why didn't you just mask the underside of the switch? Push a bit of sticky tape over the pins then trim to size. Or buy some gel super glue?
Why didn't you chose a switch that only required a round hole. It would have made far less mess of the case.
15:53 Doh! 🤣🤣🤣
Maybe your battery is faulty. I have T7 for over 4 months and it does not drain battery when not used.
The super glue and small switch is not very compatible I already destroy many small switch on that so just change and use epoxy but super glue is still the best glue for my projects

I put a big and better battery in mine and last a hell lot longer. The battery they use in this is to small.
Thanks for warts and all video 😊.
Done that a ‘few’ times
Old motto, measure twice cut once . So true
Every. Job. Ever. lol
I got one two months ago. Unfortunately it was drop shipped from China.(said it shipped from the U.S.) It worked once!
Murphy's law😅😅🇮🇹🇮🇹
