Here’s my latest video. The First prototype, I messed up the square hole for the LED display and it was a job to cram it all in but it works! Tested on my SA Collider and Quaverato last night and it works a treat.
Take a look and let me know what you think….https://www.youtube.com/watch?v=oNGxQ16tWf8&feature=youtu.be
Next step is to use a 1590A enclosure and I’m reverting to the Pro Micro now as its easier to work with and update inside the enclosure (it has onboard usb) I’ll also be dropping the LED display and reverting to 8 LEDS, I just prefer them, but the code is still there for the 7-seg if needed.
Now moved the code to a Pro Mini, they’re about $2-$3 and I built a small programmer to program them without soldering pins to them. Final Build of the Project before boxing up. Uses a Pro Mini (not a Pro Micro as I say in the Video). I’ve added two more functions; A DIP switch to choose 6 or 8 presets and a Hold switch function that also selects between 6 or 8 presets. Next Video will be the finished and boxed item!
Here it is!Hi Brach,
I’ll be putting it all in the enclosure this afternoon, I’ll also be adding some code to read a dip switch and including the dip switch hardware ready for “future expansion”.
I’ll post another video of it working and boxed when it’s finished.
Great ideas Brach, thank you! I was thinking of going even smaller with an ATTiny84 (the 85 doesn’t have sufficient I/O) but by using the Pro Micro I can easily incorporate a dip switch and was thinking of another mode of ‘hold FSW for x seconds’ to toggle mode. For now I’m going with the design as it is because I really must get on with finishing my Quaverato Kit!
By staying with the ProMicro (that has built in USB for programming) it’ll be easy to change the code to, for example, increase the presets to 8, I could then use it on my Source Audio ColliderNext steps….Now programmed into a Pro Micro….Link to Video…Click on Me.
Thank you! I looked at the tiny but didn’t have enough ports for the 7 segment display but when I was just using 6 LEDs it would have worked. But the AT micro will do the job so I’m experimenting with that now. Will keep you posted!
Can’t seem to edit my previous post, so I’ve added here. I just realised that there is a difference between Physical pins and logical pin assignments and now they do all make sense. DUH!
Having looked at the myriad of specifications….I think I’ll stick to the Roll-your-own! THey sound fabulous so why change. Thank you for your patience and help.
