what electronics with sound would be good for a spirit pack?
i was gonna get the frankengeek one but it has been sold out for a while so im looking for alternatives
If you like building something by yourself and know how to use a soldering iron try the Arduino Build b Count de Monet on GitHub or in this thread 
Frankengeek regularly restocks. Follow his fb page, since he announces restocks there. I liked his MK2 kit so much that I bought a MK3 one just so I could add the vent relay functionality and have a constant hum without switching to the song mode.
I went with the sound board and light kit in the GBfans shop. I couldnt be happier…

Id wait until sponge face has stuff in stock. All his stuff is usually top-notch, a lot of flexibility too. Gbfans wand kit won’t fit in spirits wand. Sponge face, you can buy his spirit wand lights, Matty or Hasbro wands and hook it up to his pack board
