Sam, Wonderful to see this all coming to life already ! As we at the organ museum are going to be returning both instruments to how they left the Compton Works, in 1938 and 1952 respectively, all of the extras that were added after the instruments moved to Leeds in 1965 aren't going to be returned, however due to their history in their own right, deserve to live on - and i'm so pleased we could agree for them to come to you. In the photograph, for your eagle eyed viewers - the console on the right of the two "Tub" consoles, is the Parkway Hotel Leeds, the very first british electronic organ, the Compton organ company had prior to this, been building "Melotone" units, that were added to their cinema pipe organs to add to the specification, but these were a handful of stops meant to add another tonal colour, not complete the whole instrument. The "Theatrone" was the next step in this technology, with the rotating electrostatic generators to produce the tone, this used the first generation of tone generators - of which there are very few remaining, of the three sets Lucien managed to collect, we will construct one "good" set in order to return the organ to how it left the Compton works. The second of the two, is the organ that was purchased by the Broadstairs corporation in 1952, to be used as a mobile organ for the council. However, most often used on the band stand from what I gather - this used the later 347 metal generator racks, as we've discussed before, another item you will be getting ! On one hand, it is a shame they were altered to such a degree in their last home, however on the other - they likely would not have survived otherwise, it is our intention to restore them to their original form. A note on the percussions you were talking about ! The Chrysoglott (Pronounced Criz-o-glott) is a series of soft hammers, that strike large metal bars - usually, a vibraphone but with the motor turned off ! So, i'm not actually sure why he had them as seperate devices in this case !? And the Glockenspiel is as it says on the tin. All of the "relays" you describe are Kimber Allen Pulldown Magnets, off the shelf from a company in Kent that are still to this day producing organ components just as they have done forever, a real old fashioned firm, and certainly worth a visit ! Also, the blue speakers (Why that shade of blue !?) that have Rotafon in what I know to be wheelybin letters ... Those are all, infact, Leslie speakers ! He just called them Rotafon to stick with the Compton names for things, despite them being very very different, i'm so glad you will be able to use these, too ! I really should get my act together and get our own youtube channel up and running, considering the amount of projects we have going on at the moment, Jamie keeps suggesting it but this has been somewhat of an encouragement !

[@EastMidlandsOrganMuseum]

@@JesseBadut14 Quite right ! Usually they are the same thing, just it becomes the Vibraphone when you switch on the motor for the rotating baffles. However for some reason in this case, Mr Stockdale had one of each !

[@nicholasmechak4207]

Humble suggestion: the vibraphone is one of the only instruments where you can play a note and then decide when to stop it later. You can do this electronically with piano and organ too, but I think it'd be pretty cool to have a mute for every key that can either be activated via a midi off message or even a separate midi channel.

[@althejazzman]

Surely the note decays slowly, like guitar which you can also choose to stop, or instead any wind instrument that stops when you stop blowing!

[@MuntyScruntFundle]

Grab an old sewing machine motor, if you pick one up with all its wiring you'll also have a ready built speed control and they can be really quiet.

[@karlfischer1011]

the trolley under the vibraphone is typical of orchestral mallet instruments of that era, and even now to some extent. I remember pushing the xylophone from the band room to the gymnasium for an in-school concert and the legs of the trolley folded under itself. We had to make some modifications to repair it. I would recommend building a sturdy base for your vibraphone :)

[@Seblington]

Well well well, how interesting. Back in 2020 I was offered this whole setup along with some tape recorders, the organ was way too big for me and everything had been hand painted over, was a shame really. The main musical side of things was housed in a very cramp room, whilst the driving electronics was in a shed opposite. I did purchase most the recorders as I collect Leevers Rich equipment, and it seemed a shame that the organ might end up in landfill, but its great to see it actually survived.

Wow. What a great find. I saw one of your performances recently, on KZbin. You are just awesome for putting these videos together. Thanks.

[@toplak666]

Honestly, maybe the way to go is a NEMA 17 stepper motor with a TMC2208 driver. Perfect low to mid speed controll, enough torque, nearly silent operation (provided you use a silent stepper driver like the TMC2208 or similar) and easy to control via arduino with the AccelStepper library or something similar...

[@flomojo2u]

Unfortunately I've tried this type of arrangement, and it's great up to a certain speed before it starts vibrating due to the resonance of the motor and the drive frequency itself, since it has to commutate the coils at higher and higher speeds. It's too bad, but you're stuck at lower frequencies.

[@JohnHenrySMH]

Beautiful. I'm sure I'm not the only one who instantly wondered how this would sound playing Wintergatan's Marble Machine song!

[@ScottsSynthStuff]

A critical differentiator between the vibraphone and a glockenspiel is that damper that you kind of glossed over. That's a major part about the vibraphone sound - you can engage the damper to silence a chord when moving to a different chord, to prevent dissonance. Without it, you basically have a glockenspiel. I would suggest adding a solenoid programmed to respond to the sustain pedal CC, that actuates the damper, but in reverse - so when you press the sustain pedal, it damps the vibraphone, like an actual one does.

[@LOOKMUMNOCOMPUTER]

Yeah it's cool but the dissonance is lovely too :D

[@LOOKMUMNOCOMPUTER]

It has a solenoid on that. I didn't mention is cus not as interesting as the wobblies

[@EastMidlandsOrganMuseum]

On the pipe organ side of these, you would quite often have an individual damper felt per note, with a seperate stop key that would activate a larger pneumatic to lift them all up at once, quite useful ! Some even had a "Half blow" feature, able to cut the wind in half, in order to soften things down even further.

[@caddelworth]

@@LOOKMUMNOCOMPUTER Yeah, the damper should be a simple MIDI on/off; should be easy to do for a chap of your talents, Sam LOL! And having at one time gigged with a vibes player for a few years, yes you DO need to be able to program the damper as well. 😉

The diodes on the relays are for flyback voltage suppression as the coil is de-energized, it does make the coils polorized so they need + and - right , but you need them somewhere in the circuit, maybe the new drivers have them. Fascinating work.

That's really cool. Never saw a vibraphone up close.

Could work for near-term recordings. Definitely has the low-speed control. 😅👍

Have you ever considered putting magnets into the keys of the church organ, then putting coils under each one so that the keys will spookily play themselves ... maybe for Halloween?

[@LOOKMUMNOCOMPUTER]

yes. sadly its a big modification job. and would likely take the console too far away from its provinence. but who knows! maybe a sleaker less intrusive means will rear its funky head.

[@EastMidlandsOrganMuseum]

A very rare thing to see, especially on organs - however not something that doesn't already exist ! Moving keys on self playing instruments was as Sam has described in other videos, a very American thing. Not popular over here as it can harm repetition, however that being said, Kimball - the pipe organ builder in the states, and later electronic organ builder, produced a series of electronic organs that could play rolls, and these - had moving keys ! Very fun, but so rare in the UK, we've never been able to find one for our own museum. kzbin.info/www/bejne/qWq2Zaqwesuqps0

[@Juttutin]

​@@LOOKMUMNOCOMPUTERgiven the current rate of progress, in five years there might be some slightly used but obsolete fully dextrous robotic android arms floating around. Not sure that's the right kind of (not) obsolete you're going for tho...

[@aserta]

@@LOOKMUMNOCOMPUTEROk, how bout this. No permanent modification, not even a temporary one, just one you can use when you want it to play on its own. Make a wooden frame that rests on top of the claviature. That frame consists of an MDF board and two uprights that are its legs, but also go up as well (so in profile from the front, it would like a wide H). At the tip of each of the keys, on the MDF board, one hole is to be drilled, and one tube is to be glued in place. This tube sticks (again) both up and down from the MDF, and i'd say it should be one of those plastic electric conduits, but... it ultimately is tied to the coils you'd potentially use (be they hand would or already existing items, which is up to you). Now, you'd need wooden dowels to go through each of the tubes, and they should fit loosely inside and rest on top of the keys, protruding out of the tubes' ends up top. By how much, to be determined. The tips of these "sticks" should have cue tips (from billiards). That's a soft (easily replaced) surface that won't mar or damage the keys in any way. Next would be to add a C channel piece of metal up top (this has two purposes, it weighs the whole contraption down so it doesn't vibrate off and it's also robust enough for its intended purpose). Nothing too heavy tho, and of course, something you can bend. If you can't bend something like that, then it can also be accomplished from a plate of metal with angle iron on its sides. I'd say that the plate could be 1 mm sheet and the angles 2 mm metal one. On this plate, you'd need to drill holes above the sticks and stick springs to the sticks that only just keep the sticks off the surface of the keys. Then... we come to the relatively complicated part and actually where the project would start on account of the fact that you either have these coils already or have to make them to wind them, to suit existing tube you can find. The coils would stick over the tubes (at different height intervals if the tubes are too close proximity) and they would energize using a piece of metal tube that's either slipped over the sticks (which affects the pull power of those springs mentioned above) or the sticks are cut in half and stuck into the metal tubes. Each time you activate a coil, it pulls down the metal, which is tied to the stick which then pushes the key through its cue tip. In theory, you can have this move with quite a bit of accuracy when playing. In practice, a prototype should be build to test out just how much acting force you need on that spring, which is the key component of the whole affair. Visually, it wouldn't be too heavy on the eye, it reminiscences of the organ tubes in a way and it's also silent. So it won't detract from the organ with noisy activation mechanisms. If you tune that spring force perfectly, it won't affect the keys in any way as (potentially) a motor would (rolling key presser as some retrofitted pianos have). Just a thought.

I learned my lesson properly with Joan's organ and I say cut those wires with great abandon! The vibes sound amazing. Can't wait to hear the rest of the instruments!

[@TheMovieCreator]

One note, those diodes are for flyback voltage-spike protection. Now, while the ULN2803 of the solenoid board you have got its own set of protection diodes internally, it is worth noting that not all transistor-array chips got these for people looking into designing their own driver boards. It's a very common beginners mistake to have motor and/or solenoid driver transistors blow due to lack of protection, and I see the engineers behind the vibraphone got around this by just using solenoids with the diode already built-in.

[@LOOKMUMNOCOMPUTER]

I'm pretty sure most people know about adding protection diodes. But indeed. Cheers!

I love these midi controlled instruments! I'm imagining a whole room of them with mics everywhere that you can use with a computer like a live vst plugin.

[@RobSchofield]

@ 12:33 - you have a brushless in place (the servo). You need a good quality DC *brushed* commutator motor, with pretty strong shaft support bearings (the side load on the servo from the rubber belt was what was causing the bulk of the noise). A decent, high-current H-bridge shield for a UNO R3 or some such should drive it, with a current capability of about 2 - 2.5x the peak current draw of the motor. Strangely, the motor you took off looked like a modified London bus wiper motor (probably Lucas) which would have done the job fine. Why not try that? You also need to watch the belt tension. Alternatively, use *two* brushless servos driving the shafts directly via flexible couplings (take the pulley wheels off), one for each set of tremolo butterflies, which will not have any side loads and can be synchronised for position to keep each bank of butterflies in phase. Great project!

[@LOOKMUMNOCOMPUTER]

Thanks for the info! Excuse my knowledge if wrong but I'm pretty sure servos, well the cheap ones I had are almost certainly brushed motors. I meant brushless purely from the point of a lower end kick but also high rpm with low noise. I want it to rev up and down via the digital input quickly and quietly but no need for torque. The first thing I tried was a brushed motor I had but for whatever reason it wasn't working so I switched to servo. I tend to work with what I have on the day. Especially when needing to finish projects for videos (like this) in 2-3 days postage becomes risky so I rely on what's in the drawers. As for the motor on the vibraphone it was a 230v geared motor so I'm assuming bus wipers used 12 or 24volt supply it's possibly not? I don't think it would do what I'm hoping I want to get up to atleast 300rpm on the shafts and slow as 20rpm I don't think that would Have done it. Also how bodgey it was and also the weight and mismatch of voltages. Trying to keep the whole room at the standard of 12v and 1 power input per machine. Anyway thanks for the thoughts! Think I'm going stepper motor. Cheerz.

[@packratorama6266]

​@@LOOKMUMNOCOMPUTER FWIW, the vast majority of the noise caused by servo motors is the internal gearing mechanism, because the tiny DC motors in there run best at high speeds, but results in low torque. The noise has basically nothing to do with the brushes or DC, so don't write those off. The setup is actually quite inefficient because you first have the internal servo gearing that reduces speed and increases torque(with resulting power losses), and then your external belt-driven system that then re-increases speed. I suspect the steppers will also be noticeably noisy despite fancy drivers, just because still at their core they are discrete, almost digital, devices and will have cogging noise effects. Hopefully I'm wrong!

Those diodes in parallel with the relay coils are likely flyback diodes to prevent negative voltage spikes as a result of suddenly disconnecting an energized inductor. I'd suggest reconnecting them in the opposite orientation so they aren't shorting your arduino GPIO but allow energy stored in the coils to be released.
