Step 2: Getting it ready for experiments

In order to work with this circuit, we need to replace all of the useful internal wiring with wires that we can use. To start with, I've replaced the "Lock" switch with a simple wire jumper - although you could just switch it to "unlocked" and leave it there. If you choose to replace the switch, you have to desolder the three connections of the switch - a hit on each joint with the vacuum pump cleaned things up nicely enough that the switch fell out. I just put in a little wire loop and resoldered onto the two "unlocked" pads.
Hi pal, I've looked at this project a number of times and always been tempted by it. I'm wondering if you ever solved the beep problem with regards to the record button? I have five of these sat next to me and I'd really like to implement your design in an instrument I'm planning to make.<br>last but not least, in your opinion do you think a resistor ladder keyboard could be used in place of the resistor pot to control the rate?<br>cheers in advance
Really cool, looks like a fun machine, thanks.
This fantastic project was made as part of the Tangible Interaction course in <a href="http://dms.du.edu">Digital Media Studies</a> at the University of Denver.
Looks interesting, but I don't think it's available here in the UK. Do you think it would be possible to make this toy be an &quot;echo&quot; device?
You could try, but the problem would be that the low fidelity would recirculate in a bad way if you tried to do feedback (for repeating delays). Also, it does not record and play back at the same time, so that would limit its usefulness as well.<br><br>Good luck on your quest!<br><br>[ddg]
