I'm so impressed with this I've ordered the 5 boards from PCB Way this afternoon, this will be so handy in my Radio Amateur workshop, Cheers Richard & Det, I'll download the software when I receive & populate the board.
Thanks for your support. You won't be disappointed, Mr Bleep is stupidly fast and thanks to Detlef working out the debouncing issue early on it's also very reliable. This was totally a joint effort
@@LearnElectronicsRepair It will have a baptism of fire though, I've been given a non working HP bench multimeter, there's a shed load of of diodes & semi's in there, is will help me no end I'm sure ,like you Richard once I take my eyes of the board I'm lost, so I'm going to work on one of the many boards at a time.
I’m very impressed .. when I was looking for this feature in meters (and didn’t find it) I assumed that Fluke must have had a patent on this way of testing, but I guess not. Well done guys 😀👍
Actually the colors of the rgb led has to be changed.... Short should be red as in fail red then normal diode green and the Schottky blue as that makes more sense other then that good job guys and if you could add zener diode with yellow led then you got all covered
This project would make a nice logic probe style tool if it used smd components and a teeny voltmeter. Just a thought. In any case I shall be building it. It's pure genius.

That's an awesome little creation. I have a Fluke 115 meter, which also has the diode test options and it's very convenient. I'm just starting my adventure of learning electronics. I wish that I knew enough about electronic circuits to build useful things that are needed. Hopefully, just maybe, one day I will be able too! Great video!
Great video guys, I’ll be ordering some as soon as I can, oh and by the way, I received my prize today from LEC , Thankyou so much, keep up the great hard work you’s put into making these videos, cheers.. 🤙🏼🇦🇺 Joe from Australia 🤙🏼🇦🇺
Very nice work. I ordered 5 PCBs which came in yesterday. The parts to set them up should be here today! Any chance someone already designed a case for it? :)
Update the boards have arrived, I'll build mine when its going I'll keep one more of the boards ,the other 3 I'll give to other radio amateur friends and spread the love of electronics
Can you do a demo of how it works doing a drag across lots of pins to identify a short? This is something a lot of techs in cell repair industry would do.
My 50 dollar Neoteck does not beep on diode mode at all , I have to press the function button to get the beep / continuity mode ......... It does not read a diode on the beep mode ..... I did see your new video on Mr. Beep boards with Det ..... That's why I'm on this video refreshing my memory from 4 months ago when I watched this video........... I need to get me a Mr. Beep....
Can this be modified to also find shorts? e.g. continuous bleep when meter leads shorted (adjust using a pot), then the more rapid the beep, the lower the resistance found. So as you get nearer to the shorted component, the more rapid the beep (or perhaps the lower the beep frequency). Is it sensitive enough? maybe if a short (
@@budgiefish Are you reading our minds? Det and myself discussed this very same thing but decided Mr Bleep was good to go as a standalone tester. As the say though, watch this space 😉
Hi - Do you fancy some troubleshooting on this? - board bought and built but i don't have the same operational outcome as you! I get a beeps for normal diode but they are long - maybe 1000ms (the code does say 80ms...) , no beep for schottky, no activity on the neopixle. Any idea on what ive done wrong?
Great video ! .... but that measurement is a quantitative one. A real qualitative measurement would show you not only a possible defect of a diode, but also it's value, as you showed it with the Fluke. But there are also defects of diodes, which will vary in the forward voltage drop. By a first sight, this would probably go into a good diode. But if you watch the forward voltage and it will change over a few seconds, then you also have a defective diode. Means in general, there are components which seem to be good, but they will change their behavior over the voltage and/or time applied. Voltage dependent defects of components. Go figure 🙂
Does MR. Bleep Bleep at 50 ohms? I learned from Leo's bag of tricks video that Flukes do bleep at 50 ohms and it is not a short in my understanding. It is also a reason why I have not bought a FLUKE. I'm wondering if I should make Leo's version or MR. Bleep. Maybe both :)
@@LearnElectronicsRepair That would presumably depend on the threshold voltage you have used to trigger the different indications. With a 1.5mA current source through 50 ohms you would see 75mV across the probes, which is quite a bit lower than a Schottky diode but certainly not a short. This is certainly something I'd suggest could be improved to make it more useful.
OK, I see in the other video where you go through the code that this is a simple setting that can be adjusted in the source code. Maybe it could be extended so that there is different/variable tones depending on the voltage drop as you approach a dead short. I'd also like to see an easier way to download the schematic and source code files without having to register on some new download site, or download the IDE tools. Just some suggestions for improvement.
Have you considered adding a low value fuse with crowbar protection to limit the rather undesirable affect that would occur should a voltage source be probed by mistake?
No, we added an 8 pin DIL socket for the cheap as chips microcontroller instead, so if you trash it by accidentally probing a powered up board then you just plug another one in 😆
Excellent! First class and so helpful both as a project but also as a capable tool to use. Will there be a housing for it as I do think that it would be better for storage like your multi meter so you can have the unit maybe even a kick stand so the read out can be housed also giving stability placing that at the top or bottom. Great project though and ideal for schools where I think more of this should be done, instead of meter work or whatever it comes under.

Other videos for this showed the schematics and they are up on PCBWay per the video description " And it works real good! here you will find links to everything you need to build this amazing little device. Gerber files, Source Code, Schematics are here. If "
You see, I'm not going to replicate this device; it is the fact that you learn nothing in electronics unless you explain the device hand in hand with the schematic showing how and why this approach or that is taken. i'm just advising how to make your effort more useful@@GregM

@@LearnElectronicsRepair you also need an extremely low energy standby mode, because who use a on off switch now day, I still think 2 CR2032 can be a bit too big
As Rich stated, we were thinking about a Micro Mr. Bleep. Running from 2 coin cells, a lo power LDO instead of the 7805 and completely SMT. That would defy the target audience we had in mind: the current version is intended for beginners - that's why it's all through hole. No promises - but we may do one just for fun in the future
