Thank you Jessica, for the donation.  I’ve messed around with similar devices with some fun results. Stay tuned for noise.

Found this Muson toy Synthesizer in the storage shed. Fired it up and it is in proper working order. Unfortunately it’s missing one of the sequencer plugs and currently only plays 9 of the 10 notes. This prompted me to open it up and try to determine the resistor value of the missing plug.

The 1978 Muson Synth toy. Perfect working condition, but missing one of the sequencer step plugs.

I poked around and found several interesting bends so I’ve decided to build a new custom case for this. I’m currently in process of removing all the control components that are mounted directly to the board and will move them to a new control panel.

Rewiring the controls and probing for bends.

More to come…

Dragged these out of the attic a couple weeks ago and have just tested them. Unfortunately, they are DOA. I’ll see if I can bring them back. Anyone have schematics or any other info on these?

Finished this new gadget over the weekend. It’s another Yada looper voice recorder toy combined with a echo voice changer megaphone. Check it out.

This thing arrived yesterday and it looks promising.  It’s from a series of toys called Beat Blenders.  They each have a different theme (this one is Hot Hits) and there are 3 different parts that you can combine and sequence into a jam.  There’s Drums, Rhythm and Melody trachs and around 5 different parts for each.  Moving the slider at the bottom moves the “playhead” of the sequence forward or back.  There’s already a few obvious enhancments that can be made.  Tempo/pitch can be expanded, volume knob and instead of the slider i’d like to have direct access buttons to the different parts of the sequence.  There may also be a way to randomly jump to different parts of the track…. if so this thing will ROCK.  Stay tuned.
