In this episode of DIY or Buy we will be having a closer look at a cable tracker. It is a tool that is used to locate wires in you wall. This is helpful to drill holes in your wall or to locate a fault in your wiring. I will show you how the sender and receiver functions and afterwards I will create a super crude, but functional DIY version in order to find out whether we should Buy the product or create our own DIY version. Let's get started!

Congratulations for this amazing video. It immediately became my top favourite because I was searching how to make one myself. But I have two questions: I can only find sn74hct14n instead sn74hct14dt what is the difference between the two? And the second is how many ohms should a resistor instead of a potentiometer be if I want the frequency be around 1Khz ? Thank you very much for your help. And again bravo for the tutorial.

Super cool video! I might have watched it more than once... I've used these toners many times for low voltage work and eventually replaced the most of my cheap analog versions with what I believe is the only digital version (Fluke intellitone) and is priced as such. Using the second version is a must in a building with noisy (rf) cabling. Might be an easier win for the DIY, but maybe not.

The diy style could be even simpler, and the opamp you used is definitely not good for audio. Use the C4558 instead, or the NE5532.

@GreatScott Is it possible to modify the DIY version to have 2-3 antennas to pinpoint the wire for more accuracy? 2 antennas 3 inches apart with a comparator between their output stages should work, right?

Could you add a stealth mode to a microwave? It would disconnect the beeper when enabled and would reconnect it after some time after it detects a beep, so you won't have to manually disable it. This could prevent so many families from getting woken up in the middle of the night because of a hungry member.

In North America, the Loomex is stapled to the studs going vertically, and when running horizontally, drill through the centre of the studs with 1 1/4" of wood on either side. Loose cable flopping around behind the drywall is not an issue, as the wire will move out of the way when hit by the drill bit.

Hi Mr scott, great video as always. Maybe I could suggest another topic: due to pandemic I recently buy a finger pulse oximeter and I was fascinated by how many vital information you can get by a single led, your lovely components. Could be very interesting to see how this device work. Thank you and have a nice day!

NEVER assume that the presence of standards means ANYTHING. Someone before you may have entirely ignored those standards. It's super-easy to trace 120V / 240V wiring with any simple audio amplifier, using your hand as an antenna.
Mervin Victa
Mervin Victa Před 6 měsíci
Prototype wiring is great for a mock-up to test circuits. Through to the '60s all valve/tube, and some transistor equipment was hand-built utilising point-to-point wiring until PCBs became the go to method. It is still done today in audio gear like guitar amplifiers and HiFi amplifiers using tubes/valves where not only the traditional characteristic sound/tone is sought after but also the traditional build method for perhaps a unique, non mass-produced piece of gear. Tag strips or turret boards, a rectangular bakelite strip with a row of lugs, are used as solder points between components, the same principle as pads on a PCB. The difference in sound tone between point-to-point and PCB construction is subjective and similar to how someone might taste wine.

Great video, very useful channel, one of the best for electronics. Since I am a noob here, looking into some basics, I would like to see occasional videos with some basics and theory behind simple electronics circuits. For example, I would like to understand how to calculate some of the values for simple circuits. For example, LC filter calculation for rectifier, or similar.

What if the emiter is shorted? on the buy version it shouldn't be a problem (well, at least, when i worked in telecom, I used this a lot to find pairs between cabinets, if the sound went away when shorted i was sure that was the right pair)

ElectroBOOM Před 6 měsíci
Great video Mr Scott (let the comments begin correcting me about your name)! Question: in your receiver schematic when using a BJT or MOSFET as the antenna input stages, the schematic shows base or gate are pulled to ground which would turn the transistors off (especially in circuit with BJT the collector is also pulled to ground, should be VCC?). So this means the circuit is relying on the strength of the signal picked by antenna to turn the transistors on and pass the signal through. Is that correct? In such case I think that's why the receiver is not doing great as you showed because the antenna is working based on a weak capacitive coupling not strong enough to trigger the circuit with existing resistive and base current loads on the antenna. I suggest to improve the circuit by biasing transistors in ON mode and just let the weak signal to get buffered through transistor. Of course the bias can only be very high resistors not to load the weak signal, or in case of BJT use Darlington to reduce base current... I think! I don't know... good luck!
Amir B
Amir B Před 5 měsíci
wrong Mehdi, the FET is biased already in ON region (VGS is biased negative) but it is not amplifying, it is just a buffer with very high input impedance so to pick up the weak voltage. the BJT collector must have been connected to VCC, unless there is a negative VEE in the circuit which I dont think there was.
Stefan0719 Před 6 měsíci
Hi there. Keep in mind that in his version of the circuit he´s jusing a JFET, which behaves different than a normal BJT Transistor. The way he´s "pulling gate to ground" is the right way to do it here. Over all his circuit isn´t to good. The Jfet should have higher resistance or a better said a higher resistor in the source line, and the coupling capacitor to the op amp should be bigger. Also, if I recall correct, I think I saw some kind of frequency selective part in the original circuit (like to attentuate other frequencies and peak the 1Khz Signal), that was done using a RC circuit. In the short demonstration that was shown, it also could be heared that his version of the circuit did pick up a lot of intefference, whereas the original circuit (the one he purchased) did receive his diy transmitter rather well. I guess he used the JFET (which behaves different than a standard transistor) to have a very high input resistance and due to that make the circuit very sensitive. So yes, for standard Transistors biasing "Base" towards plus does indeed work, but for a JFET you have to "bias" the gate ("Base") towards ground. If you put it towards +, it will make the Jfet less conductive (reduce amplification). The circuit (receiver) could be improoved using a high impendance LC tank circuit, with a coil with many mH (>10mH) and a parallel resonance capacitor so the circuit will have a resonant frequency of about 1KHz. That also would put away the humm noise you heared when he tested the bought circuit (It´s not necessarry obviously, and was left away due to cost reasons). Anyhow, just wanted to reply to you. I watch your videos too, you´re an amazing entertainer.

Circuit traces can easily lead you the wrong way as well, and if the cables goes through a large server room, it's not much fun. The two tone tracer are better distinguishing the difference between data cables and what your tracing, there also helpful with hearing aid loops👂, you can even hear people taking over landlines with them.
