[ SYNCUSSION SY-1M BACK IN STOCK - FOR THE LAST TIME ]

Post by satindas » Thu Feb 06, 2020 8:16 am

Hi All,

The currently available batch of Syncussion kits will be the last !
It was brought to my attention that the MHS122K SPST switch is now out of production and Mouser/Digikey have zero stock.

Fortunately, I managed to grab enough of the MHS123K SPDT switch which is now included in the kit.(The only difference from the MHS122K is a redundant, center "OFF" position).

Also, in order to make the boards easier to solder I have gone for a HASL finish.
This should mitigate the issues causesd by ineffective solder joints as was quite common with the ENIG boards.

That's odd- I get no search result for MHS122K on Farnell... when did you see that they had stock?
The only one of the same series I see in stock at the moment is the MHS233K.

There are about 85 kits left at the moment. 65 gone already from this batch.

Im going mad. Or something. youre quite right, they dont. Im sure i searched a week or so ago and they had 600 odd, but only as american stock. I was browsing your site and noticed the note you put up about them.

but i cant find them again now.

Apologies, didnt mean to mess up your thread.

Not had experience with either of those suppliers but definitely worth looking at... Bookmarked, thanks ;)

FWIW, another possibility:

http://www.seekic.com/icdata/MHS122K.html

...not a site I’ve ever used, but you never know where there might be a few thousand sitting on a shelf.

How much, roughly, do all the components in the BOM come to? Been wanting to build this, but curious how much I'd be looking at all-in.

The mouser BOM is like 175, I think there are are few things that are not in there + the kit , shipping etc.. its right around $500

Slightly off topic, but does anyone know if the MHS122K will fit an original syncussion? Mine is missing one S&H switch and I'd like to solder in a replacement

Looking at the schematics it seems there's an easy mod and get use of the center off switch for S&H. Instead of just disconnecting the LFO you could use one switch contact for the normal LFO input and the other leg feeding white noise into the S&H instead. Some trace cutting I bet but not difficult.

I haven't used an SY-1 but it seems odd to not have proper random modulation. What is the purpose of the S&H sampling the LFO?
