A fun idea from another forum...

Design Concepts

I just read a great idea for future midi boxes, for those wiring a dout to light an led for recording, why not also have it activate an external switch to power a red recording lamp at your studio door

yes!

great idea!

just plug a relay on a dout modules (maybe with a transistor to have more current)!!!

  1. cool idea!

Yes, with a relay this should make fun - an additional driver is absolutely required. Either a transistor, or a ULN2803 like shown here:

(this example has been made for MIDIO128, but works also great with every MIOS based application)

What next??? MIOS - RR (robot roadie) :D… hehehe

and with this we can make a midi preamp for my hifi DIY amp!!

and with MIOS it would also be possible to drive a nice graphical LCD, to add meters for the HiFi channels, maybe also a spectrometer… and a remote control of course :slight_smile:

Here some impressions of a preamp project I realized ca. 10 years ago with a 80c535
