Synthesizer Recycling for Electronics parts salvage MF#64

[@LandonBalk]

I don't know what you're talking about sometimes, but the more I try to wrap my head around this stuff, the more it makes sense.

[@markusfuller]

+Landon Balk I don't know everything i'm talking about sometimes either. and as things keep on changing I have to keep on learning new things.

[@Sequencers]

Hi Markus good vid, I have been scrapping old gear for years if you want good stuff try to get hold of on old organ some have great keyboards which can be used for a synth they are available free on gumtree and eBay a lot most people want to give them away or very cheap ! Well in Scotland ! I have built a lot of gear from scrap parts including a Minimoog although I had to make a lot of bits, thanks for posting Steve

[@kerrybradley6565]

There's one chip on that HZ-600 board that you MUST extract. The NJM/JRC2090 is a 5V 4-pole VCF chip, custom-made for Casio. It's really warm and can be nicely controlled, would make a fantastic DIY filter box! Search KZbin for modified HT-700 and/or modified MT-600 to hear it in action!

[@markusfuller]

+Kerry Bradley Hi Kerry I have already eyed those up for extraction, theres 2 of them on this board. but thanks for the youtube search info I will go and watch those. Best wishes from Markus

[@terenceedwards5175]

yammaha keyboards have a chiped matrix,the chip for the roland is on the main board

[@PWMaarten]

The 6 pin IC connected to the MIDI in is probably an opto isolator.

[@markusfuller]

+PWMaarten Yes it is an Opto Isolator its standard on all midi inputs across almost all midi devicesI thought I said that so I watched the video again - I cant believe I said Op-amp "ouch" thanks for pointing that out.

[@303otto]

+markusfuller and a new one cost 3-4€ +shiping :O so, its very clever to keep them ;)

[@markusfuller]

The main reason i keep components like this is the time it saves from having to wait for shipping. some components are very cheap but if you do not have one it can take days for it to arrive.

[@303otto]

markusfuller yeah, thats the main thing i hate too.. waiting for parts :( atm i'm waiting for 10k potis (20pcs) from asia.. man, it feels like aaaaaages :/ Without having them, my project stands still... meh.. :(

[@JakobHaq]

This is a great video in a very important topic! You should make more of these Markus! =D

[@markusfuller]

+Jakob Haq Thanks Jakob :-)

[@bestrickie2]

I would hang on to the casing should someone need it assuming it is in good condition.

[@PorchBass]

Marcus there's 2 casio filter chips in there a La korg ms... I liked the programmable orchestration but sold the ht700 I had. hz is the big key version someone must need spare keys etc!

[@markusfuller]

+James Porch Its a shame i had to strip it down but there was just too much work to get it going again. Im sure the spares will donate eventually into other gear. PS hows the new synth ?. Im getting some interesting sounds from mine :-) put it through a few effects and it sounds BIG

[@terrykelling5692]

Yes, I would like to know where theses amazing car boot sales are. I only find crap being sold in the ones where I live.

[@markusfuller]

+Terry Kelling Most of the time there is only crap at the ones I go to but I visit 2 or 3 every sunday and sometimes I come home with nothing,

[@pie213]

Can you put up a video when you decide to make one of those "little projects"?

[@markusfuller]

+Jen Pies Sure will. I hope to make a simple synth of my own one day and will film it for youtube. even if im not succesfull.

[@questionerizator]

Man I love your videos! Awesome!

[@markusfuller]

+Josef Kolena Thanks Josef much appreciated.

[@Sequencers]

Hi Eman sounds interesting have you posted it on KZbin ? If not it would be good to have demo ! I got hold of the little Gaken sx150 and was thinking of putting CV and trig in on it so it can work of a sequencer ! Regards Steve

[@WesslansFilmprod]

If this is the synthesizer I think it is (a Casio hybrid synth with spectrum dynamic synthesis).... When you got a hybrid synthesizer on your hands Markus. If i'm not mistaken me this unit got both a VCF and a DCA for the filter and Amp section. If you still got the parts can build yourself either an analogue- or a hybrid synthesizer with DSP based oscillators. Cheers Daniel Fletcher of D.S. (a Swedish synthrock / synthpop group)

[@ThomasGrillo]

Nice bit of salvage operation, there. Thanks for sharing this. :)

[@markusfuller]

+ThomasGrillo Thanks Thomas :-)

[@leozendo3500]

Super fancy scope in the background

[@markusfuller]

Not really it is one of the lower slower models.

[@marcbrasse747]

You should have added a warning though. One never has enough space to keep all the parts one might one day have a use for. Maddness lurks there. I'm speaking out of experience, believe me! :-)

[@markusfuller]

+Marc Brassé yes Marc you are correct, every half year I have to dig through and throw some boards away as I just do not have the room. I do not keep everything but if its synth related I try my best to make room.

[@rot_studios]

This is so true haha "just this tiny corner of the room" I told myself, now the corner is a really big one :P

[@grsymes]

I'm looking for a SAD 1024 chip for a Boss/Roland BF-1 flanges pedal, would you have a working one you would be willing to part with?

[@markusfuller]

hello Galscott. I have just been digging around for you and i cannot find a sad1024 bbd chip. sorry. i thought i had a couple but may have used them at some point. my apologies

[@grsymes]

+markusfuller cheers for having a look.

[@Michael_Smith-Red_No.5]

Another good video. Off to find out about the Casio HZ-600, as it's a model I've not heard of.

[@markusfuller]

+Michael Smith hi michael, it was an interesting synth but there was just too much work required to repair this and i do not think it would have been an amazing synth sadly.

[@Michael_Smith-Red_No.5]

What you had there, looked a bit unpromising in terms of a rebuild. The HZ-600, though is bonzer! It sounds freaking great. A bitch to edit, and many other foibles, but they sound really nice; and the giant wheel is always good.

[@markusfuller]

+Michael Smith Yes but things were missing and I have removed a few components only to find they are dead. The transistor I used for (how to test transistors video) came out of this and theres a few other dead bits so I guess some of the chips could be fried also. Believe me I did a few days looking and some tests before i decided to kill it.

[@Michael_Smith-Red_No.5]

markusfuller I literally had just come back from the other parts of the internet, and realized how nice this synth sounds. My last comment was to mourn how it wasn't practically repairable. I'm in the market for one, now.

[@Michael_Smith-Red_No.5]

Not yours, of course. But they're out there. And sounding nice.

[@sasarasa88]

I have an ht3000 and ht700, which are pretty much the same than the hz600. They are polyphonic digital oscillator synths with a single analog filter. I learned synths on the ht3000 back in 1988. It's sad to see this hz600 dismantled, but I understand you got good reasons. I would suggest that you try to salvage the analog filter and vca chip. As you said in the video, that could make an interesting project.

[@markusfuller]

+sasarasa88 I did spend few days looking into it and realising there was just too much to replace and gamble that it would sing after days of work. but parts will be donated to other causes so it will still live on (partially).

[@gjnieuwenhuis2440]

Bit off topic: What scope are you using? I'm looking for a decent scope for synthesizer repairs (not for other but to maintain my own old equipment).

[@JakobHaq]

"Like chopping a boat up for building a raft" =)

[@markusfuller]

+Jakob Haq That just rolled out of my imagination. I wish I could write a book of one liners like that

[@d4funky1]

Here he goes with his car boot sale bargains - I wish my car boots were like this - jealous

[@markusfuller]

+UKG-TV Many weeks go by visiting many car boots where I get nothing at all. car boots are mainly baby clothes and Ikea table lamps but you just have to keep on searching.

[@d4funky1]

I hear you -

[@torpedo35]

Old pcbs are also great for anger management as well.

[@markusfuller]

+Photon Torpedoes Ha yes I think I know what you mean there

[@terenceedwards5175]

na man any thing that does not have a chip on will interface

[@drunkentrain]

I laughed pretty hard when you said you could build a synthesizer with the parts

[@markusfuller]

+DrunkenTrain Glad you likes that one :-)

[@Leverquin]

[@brickscratch]

I like this vid Marcus, stripping the components is something I've often done due to a lack of skills, knowledge or parts. Or if you can't salvage it - repurpose it. Perhaps it would have just functioned OK as a MIDI controller? But I do like Capo Donatellos' suggestion of a MF One synth project. That would be one badass MF ;)

[@markusfuller]

+brickscratch Hi It could not even function as a midi controller. theres was just so many dead parts around the power etc and strange voltages in the wrong places. I hope some of the parts can go to good use. Yes a MF-one synth. yes i have the ideas but not all the knowledge needed to build the monster i want to create. maybe I am thinking about it the wrong way and should try building individual units up to plug together ?. Hmm my brains ticking now. tick tock tick tock ???

[@gorillaau]

This is a tear up video... tear the item to shreds and throw out the bits that are rubbish.

[@fkthewhat]

This is why I would suck at electronics... I'd have all those components removed, tested and in containers... and would likely lose sight of the big picture as a result!

[@markusfuller]

+fkthewhat I use to remove all components and box them up but it takes too much time, now I just save the whole board and go searching when i need something.

[@bobjerome5390]

hi don't keep alot of the parts i have a RS acc and i can get alot of the parts next day yes you need to get you money back i got a akai GX77 that;s in a bad way i am only fix it because it a bio transport someone did repair on the audio pre amp to the vu meters and it did a lot of reg's in and transistors in i have done more hard fix up bob

[@davidogren4554]

My profile has some preety cool beats on my profile I'm only 15 as well

[@markusfuller]

+David Ogren Hi David, the beats sound interesting. what instruments or software are you using in your videos ?. also one small tip if you dont mind me saying is hold your phone/camera in horizontal landscape mode instead of vertical portrait and you will get full sized videos without the black lines down the sides, it just looks better on youtube. Best wishes & keep making the music :-) from Markus

[@tonalaxis_AXiS_MODULAR]

Also known as hoarding.... Lol

[@markusfuller]

+tonalaxis Oh yes I am a hoarder for electronics but it has gotten me out of trouble so many times.
