IR receiver is for decoding TV remote control transmission. You can see the square wave of the remote and the digital code of the key you'r pressing.

The shaky hands problem is called essential tremor. Many of us have it. In this case, the word essential is medical speak for “We don’t have a clue.”

Great little device, but it has one downside - battery drain. If you plan to use it less than few times a year, add mechanical off switch between battery and PCB. It will save battery from going flat.

I have had the same device for some years. I bought this over other models, because of the compactness and the fact that it has its own battery. The IR receiver is to decode remote controls and indeed, it does for lots of different remotes. Overall, very nice and useful device.

One option is to get a little piece of protoboard, solder two rows of pins, and connect the leads to that. Make the board stick a bit outside the socket and you can even stress-relieve the leads. With 14 pins, it won’t jump out of the socket. Even 1 row of right angle pins on a vertical protoboard may be enough.

I think that I mentioned on your yellow thingy video that I had DIYd the same type probes as those that came with your new unit. However, my three pins are on just one header. So, it is very easy to drop it into the ZIF. I prefer to be able to remove the wires, to lessen the likelihood of injecting noise from the wires, as they will act as antennae. Your slot is better than a hole, because the back will not be dangling on the wires, when the case is opened. You might add some heat shrink over the wires at the slot, to prevent wear. You might place a zip tie on the wires, for strain relief. The original yellow thingy circuit was built on a PIC 16Fxxx, IIRC. Thanks for the video.

Hello, I have had this tester for many years and it still works well, personally I would not solder the clips to be able to use them in the K+A position as well. That IR receiver is there to test remote controls working on IR command transmission. Unfortunately, it cannot decode all types of transmitters. For those he knows, he writes a function with parameters. For transmitters whose code it does not recognize, at least it indicates signal reception with a dot on the display, so I no longer have to send a signal to the camera to see that the IR diode is flashing. Nice dqay 🙂 Tom

Problem I had with TC1, is that LED panel backlight, had cold joint. After some months, screen was dark but I noticed it works, maybe it was my fault, device was in backpack and maybe screen was under pressure. Then I wire jumped all signals, and screen was OK, then when I removed wires it got back to normal. I also noticed that 4.1V voltmeter measured on battery says 3.9V on device screen. 1:20 - Battery last long if not used, when used each measure takes away 0.01V and you can see it at every start... even on your video it says 4.15V on first measurement, and 4.14V on second measurement, like with mine device. 8:45 - If you connect/short slot 1 2 and 3 with that item in center of screen, and start device, it will do self test and recalibrate. Also, I saw somewhere on youtube, that this device is stolen, some guy from Europe made design, but chinese stole it and now make profit. There is video explanation how this device recognize parts.

I've used a version of one of these from Banggood for a few years now. I find it very handy when I'm salvaging parts from some old whatever that's headed to the trash. I also use mini clips on mine , I'm not sure how many times I've had to repair a break in the dinky wires I've used on them. It's been one of the handiest things, just press a button and most time it identifies the part and gives you the stats on it. The version I have has some hidden abilities to give out a test signal at different frequencies and also can go into a calibration mode for open, short , etc. 👍

You could just get a 3 pin DuPont backshell, or glue/heat shrink the set of 3 that you already have together. That’s what I had on my old multimeter that had an inbuilt transistor tester and it worked fine.

For the long haul, probably once you decide to use better wires, you might consider strain relief for the cable. A simple zip tie inside would work or if you want to get fancy install a TRS 1/8" jack in the side of the case and make the wire set detachable. Regardless, nice hack!

@Imsaiguy, do you have a video on BJT matching? I want to take the time to say thanks for these amazing videos. I think yours is fast becoming the best electronics channel on YT, can't wait for the algorithm to catch traction. You explain things so concisely, distilling the real essence of a subject, I suspect a prior professor or lecturer. And the sheer width of the topics you've covered is wild. Based on my watch history, I'm mildly obsessed ha! Thanks again.

Some of the newer ones (still called TC1) off eBay are of much lower quality. They have no crystal, can damage zener diodes when testing and use a counterfeit MCU. By "counterfeit" I mean it says MEGA328 on it but it's a different MCU entirely which is completely incompatible and can't be reflashed with newer firmware. There's a big thread on the EEVblog about this.
