FAULTY Sheffield Electronic DRUM KIT - CAN I FIX IT?

[@flyingmower]

Hi Vince, it was me who sent this item to you. I saw it on eBay and I paid £15 with postage. It was described as having no power. I was hoping it wasn't just the on/off switch. I had it sent straight to you to save more postage costs. Thought it would make a good fix it video. Also thought if you got it working, the kids could drive you nuts with it later on. I'm pleased you didn't mind me doing this and also pleased you made the video.

[@Mymatevince]

Ohhh OK, so the sender was the eBay seller. Oh well I thanked Raj but I should have been thanking you Flying Mower. It all makes sense now😂 Nice one for sending it over. I was also worried it was going to be the on/off switch but I think it made for an interesting fault, luckily it was more challenging but not too hard. I will pin this comment. As it turns out it is me driving them nuts with my hip hop unique drumming style 😂 Thanks again 👍👍👍👍

[@willmorici5765]

@@Mymatevince That's awesome. I actually was thinking: There's Raj, sitting at home saying...."Man, I just gave away a drum set to Vince and he fixed it for 20P." Nice work, as always, Vince. What do you do with half the stuff you fix? The wife must drive you crazy to get rid of half of it! *the drum set is next, btw!*. 😂

@@willmorici5765Well most of it has just been storing up, but my house became a bit of an embrassment as every room was getting taken over with boxes. So I have been giving away stuff to friends and family and I will probably try and do a car boot sale or maybe eBay some smaller items👍👍👍

@@Mymatevince Vince, let me say that it's an honor to hear from you, first and foremost. Much respect to you. As a NASA engineer, I work on spacecraft; but my forte is Mechanical Engineering. You have taught ME so much much on the electrical side of things. Thanks and keep up the good work. Thanks again for the great content and I look forward to seeing more of your electronic repairs. I really loved your wacky projects, such as windows and plumbing. I had such a laugh with you trying to get that window out and turning the water on and it gushing everywhere.

[@MrOverstuffedcow]

Great job Vince. What a great way to come home and find another video of your fixes.

[@ekens6344]

That was great! With the voltage regulator I think you made the right call in the end. On that datasheet it looks like the original one is a BL8503-40 so that would be a fixed 4.0V output. Voltage regulators are set up to always have a fixed voltage output, so generally a 4.0V regulator would always output 4.0V no matter whether a 5.0, 6.0 or 7.0V (or higher) input, you only need to worry about not going beyond the limits of the specific regulator. And a minor point is needing to have a bit of differential between input and output so for a 4.0V output regulator you'd normally need minimum a 4.5V or 5.0V input for it to have something to work with. Again it depends on the exact regulator. Anyway, they probably used the regulator here to lower the battery voltage to a safe level for the chips so 5.0V output could well have been too high!

[@Mymatevince]

Nice one, I thought they might just step down the voltage to a % under a range of input voltage. I didn't realise that they have a fixed output. Thank you 👍👍👍

[@MrMaxeemum]

​@@Mymatevince The output should be 3.0V according to the datasheet for the regulator shows 4V input (Minimum) and 3V output (this allows the batteries to run from 6v down to 4V before the output is affected) I was screaming at my screen when you used the 5V regulator, I then took a great sigh of relief when you swapped it for the 3.3v although it's higher by 10% it should be ok but I would still swap it for a 3.0V version.

[@BuyitFixit]

@@Mymatevince Generally the last two digits are the voltage output like a 7805 (5v regulator) 7905 (-5v regulator) 7812 (12v regulator) etc, so I'd expect a 8503 to be a 3v regulator. Well done on another successful fix.

[@Mymatevince]

@@BuyitFixit That is useful to know. Thank you👍

[@iretromods2963]

I don’t know what you do but your repair videos are so relaxing and enjoyable to watch no matter what the item is your fixing even if it’s fixing a bad toaster that I’ll probably never need to fix but still watch it.

[@quanchyplimp]

Nicely done Vince. It is always satisfying to fix something when the components only cost 20-30p a piece. I fixed a TV a few months ago, the component I already had in my stock with a value of around 10cents (EURO), which was an IR receiver for the remote control. The client thought the actual remote handset was at fault. Fixing it as an amateur really put a grin on my face, a nice feeling and prevent things going to the landfill so quickly.

[@retrorestored]

Interesting fix, it’s funny how just one little component killed the whole thing. I enjoy fault finding too, and you always hope it’s not something simple. Some things take a lot of time but when you finally fix it, it was all worth it.

[@ruikazane5123]

You had me on the edge of the seat Vince! I was here saying "No! Don't use the 5 volt regulator! Use a 3.3 volt one!" and was glad to watch through...what a relief! Now with some more broken musical instruments that could be fixed there seems to be a band forming up... Those piezo things are there to sense vibration and strikes to the drum pads hence the sensitivity and velocity/hardness sensitivity (if such kit does have that!) So the LDO (yes it actually is) that was originally in there is a CMOS part (known for low idle power consumption but a bit fragile on high current applications) in a tiny package (cannot dissipate the heat well)...must have heated up and died out that way. Personally it is not worth getting that same exact LDO for a replacement only to fail once more...I would have used a fixed-voltage 108x (1084, 1085) or jig an LM317 on there! 3.3v seems to be the ideal spot for that blob chip. 4 volts is a bit of an oddball, maybe conversion to 3.3 seems to lay burden on the regulator considering input voltage so raise it up...Or to account for droop when the batteries get weak. Remember that as input-output voltage differential increases the current capacity drops down too

[@Mymatevince]

Thanks Rui for the detailed info👍👍👍👍

[@Adrian_Finn]

Really enjoyed this. Don't be afraid to use flux like normal when using low melt solder, it's a lot easier to use and doesn't stick and spread everywhere and keeps in a nice flowing blob rather than turn stodgy and sticky.

[@Mymatevince]

Thanks Adrian, on my next video or maybe the next next video I did use flux with the low melt after reading the comments on the Mega Drive clone video (I think it was) 👍👍👍👍

[@scouse1967]

Vince: "can it as easy as the on and off switch?" Me: "no Vince it can't. The video is 42min long." 42mins of pure enjoyment and relaxing 😁

[@avatarsven]

Excellent video. I had the exact same issue with my e piano and my ultrasonic bath. In both of them the 3.3V regulator has failed. I have no bench power supply, so I took 3.3V from an ATX power supply. I think these regulators are often undersized and likely to fail. So I love the fact you replaced it with a bigger one, I wish I did so either but I took it from another board and now I can wait for it failing again 😂

[@Tim_3100]

An unusual one for you Vince but great thing for trying to fix

[@DEmma1972]

Nice fix wow that globtop is huge the biggest blob i have ever seen it can basicly fit a whole packaged microcontroller under it with package and all i wonder if its a custom asic with mcu and audio and drum circuits or its just a microcontroller with code i so wonder if it houses more dices like a mcu a drum synthesizer etc

[@309electronics5]

Also these voltage regulators are linear they are basicly big resistors wich limmit the voltage and throw exces in heat also the ams1117 are used in arduino development boards and their number might indicate voltage example 780[5] 5 volt 7812 12 volt thank me later for the info

Those piezoelectric speakers are microphonic Vince just like how you can use a normal speaker as a crap microphone, when the crystal flexes from being hit it’s generating a voltage.

[@Mymatevince]

Thanks Gower, I never knew that! I have only seen them used on cheap handheld games for sound. It was nice to see them being used as a microphone 👍👍👍👍

[@SimonNemeth]

@@Mymatevince Not a mic, more of a variable impact sensor. Even the expensive ones work the same.

[@ralphj4012]

Well done as always. However, use caution (you corrected yourself) when injecting voltages, changing regulators etc. Many micros which normally run at 3V / 3.3V may have a maximum working voltage of 3.6V (3.5V from a noisy power supply may damage them and 5V certainly will).

Voltage regulators put out a fixed voltage, independent of the input. You need the correct regulator voltage, not just any voltage.

The exact value of tour regulator should be written on the regulator as a code.

I don't know how, but I read the video title as "Sheffield Lab Electronic Drum Kit".

Exited full screen mode & then realised I read the title wrong. How in the world did I imagine that Sheffield Lab made any sort of equipment is beyond me. Wot a git.
