AVAILABILITY Have some more samplers almost ready to go, unfortunatly supplier sent the wrong parts so have to wait for replacement. I hope to have them ready to go next week (WC 6th June)!

This is a simple mono 8-bit sound sampler for use with Amiga's, connecting via the parallel port. It is based on "echolevel's" design available on GitHub. I had the PCB made (with a couple of minor tweaks) and designed a 3D printed case for the sampler which has the DB25 connector on one end, two RCA connectors on the other and signal gain control knob in the middle.

The 3D printed case is available in White with Grey text.

While there are two RCA connectors on the unit, the sampler itself is MONO ONLY, meaning if a stereo signal is applied, it is mixed into a mono signal then sampled. This was a design decision taken to vastly simplify the circuitry and also because most Amiga music module creators use mono samples.

If you have a mono signal then only one of the RCA connectors needs to be used (doesn't matter which).

Here is a rambling video showing the sampler's operation: https://www.youtube.com/watch?v=Eji0Wg25V3g

IMPORTANT! When connecting or removing the sampler to the Amiga ENSURE THE AMIGA IS TURNED OFF! Old machines like these are quite sensitive to this and, given the age of the internals of the computer, probably more so these days!! I have tested on my Amiga A1200 and haven't had any issues but care is always needed when attching to older machines like these.

I use this process: - Turn off Amiga - Connect RCA leads to sampler - Plug the sampler into the Amiga's parallel port - Turn on Amiga - Use sampler to sample sound - Make music!

I actually made this for myself just for fun as I am not that musically minded. You can see in the video above the visualiser I use to test the samplers.

Postage I am doing this as a hobby and will post out as soon as I can. Given the current world situation the deliveries may take longer than usual. I will be using Royal Mail.

Please message me with any questions you might have or if you are interested in buying one but I don't have any in stock!
