Very nice and self-contained solution at a decent price! It does exactly what it is intended for and it's obviously a lot easier to use and set up than a regular signal generator & amp/oscilloscope.
It does the job, best probe I have seen is Mr Carlsons lab super probe which is ideal for rf circuits. It is very high impedance because it is non contacting! Ideal for radios, transmitters etc ! It also features noise detection circuits for tracing crackling, noisy resistors, and frying eggs background noisy resistors!
I got this pen to use to test the audio output signal on a 1960's battery powered transistor radio. I'm not getting any sound, and I want to see if the problem is in the audio output section of the radio, or if it's before that, ie. in the RF section. IF I can get sound out of the radio's speaker, then I know the issue is in the RF section. Problem is I can't figure out how to use it. I want to see if I can inject the audio signal from the pen into the audio output section of the radio to see if can get that injected signal to come out the speaker of the radio. I'm sure it must be simple, but I'm a newbie and trying to learn something new. Any help on the connections is appreciated. Thanks.
Any idea if this would work for tracing 12-24VDC pedals? I'm guessing I'd need to power the pedal with separate power supply but just curious if it can handle higher voltage tracing? Dont see any voltage ratings in the build docs.
@@erikvincent5846 Thanks for getting that info and clarifying that. Good info to know as I have one or two higher voltage pcbs projects that I still need to get around to troubleshooting one of these days. Looks like a cool project and will work the vast majority of pedals out there.
Has anyone bought this that lives in the united states? I'm a little worried about shipping from Europe. Is there any where to buy it from in the states, or is the shipping reliable?
Dude, this thing comes from a shop in Germany. As far as I know your purchase is protected by EU customers protection laws. Shipping to the US takes about two weeks, how long it will stuck in your customs is anyones guess. You can order with tracking number. So don't worry, it will work and you will have an awsome gadget. I ordered mine yesterday.
cool tool, might get one. last time i had trouble it was a grounding issue from a solder joint to the back of a pot and the time before i didn't turn the volume up. 😂 also, like? aren't you basically playing operation? 😋😂

I made my own using an external sound generator. This is such a streamlined solution! Much better.
Thanks. I've had my injector pen for a couple weeks but haven't put it together yet
Thanks for the info. I've got a couple of dead pedals that needed this. Just ordered one.
Thanks guys, this looks like a great tool to have
I’ve just ordered one. Thanks :)

Amazing tool!!!
Would I be able to test 500 series gear with this? I assume so but just wondering!
Like rack mount equipment? It would work, assuming you have a good schematic for what you are working on.
@@erikvincent5846 Yeah, for rack mount gear. I have a DIY kit I can't get working, I don't have the schematic for it, however.

I just emailed Thomas over at TH Customs. I know there is an LM386 on board, so a maximum of 12V, I assume. But I'll let you know what I find out.
I got a reply back. It's designed for a 9V system, but everything on that board should handle up to 12V without issue.

Is this suitable for tracing radio IF or AF stages?

Pretty much. Although, this time, I want to make it "alarm"
@@erikvincent5846 looks like it’s going to be a cool pedal, I’m enjoying these videos a lot, but I can’t get LTSpice to show a output waveform. 🤷♂️
