I'm not sure exactly, but quite a bit. If you do the double, the kit is $150 more than the PCB alone. Little breadboards are like $2 shipped from China on ebay, get 24 pots from Tayda for $0.65 ea. Buy all the common parts like resistors/dc jacks…
This page has digikey part #s for most components: http://casperelectronics.com/finished-pieces/nova-drone/parts/
There's a LED you have to get from sparkfun, and if you order cheap pots from Tayda electronics, you'll save a bunch over digikey price…
Not exactly sure, I was buying for about 4 other projects at the same time, and I had a bunch of the parts lying around. The biggest expense would be the 24 pots (although Tayda has cheap pots that fit for around $0.65 each), the sp3t switches (I c…
Any 9v center positive power supply should work. Minimum 600ma. Anything over 7v should do it, actually.
Or 6 AA batteries will run it for over 8 hours.
It was still running when I got home at 4am, died sometime before I woke up. So, 6 2700mah batteries can run the LXR for over 8 hours.
Cool, thanks for the power supply tips - I'll try that out. This headphone amp is supposed to get 30-50 hours o…
Anyone know if there would be anywhere I could pull +9v and -9v from the LXR? The headphone amp needs both - right now it's powered by two 9v batteries, but it'd be nice to get rid of those and just pull power from the LXR if that's at all possible…
I removed the standoff in front of the mainboard, and now the battery pack sits perfectly under the right side of the front panel. The headphone amp is on the left side with its own batteries. I just plug in the AA battery pack and the headphone a…
I haven't run it long enough to run the batteries out yet. I think it'll run for a while though. It's 6 x 2700mah batteries in series, so 2700mah @ 7.2 volts... I haven't checked what the LXR draws, but another thread suggests maximum draw is abo…
Kensington, the door right beside Graffiti on baldwin. https://hacklab.to - they do an open-house thing tuesday nights after 6pm. Just stop by and walk right in, everyone's pretty friendly. I met a modular synth designer guy there last night and …
Incidentally, if anyone wants my old frontplate, you're welcome to it... I'm in Toronto. It's a little loose around the buttons, but it works.
This one:
I made my first frontplate from a piece of acrylic by hand with a Dremel, but the nice looking cases are made with laser cutters. Not a tool many people would have at home, but there are most likely a few commercial laser cutting places around wher…
I laser cut the frontplate from Shiftr's case design last night... The button feel is a lot better now that the frontplate supports them a little more.
Yeah, I've been either using it as a master or slaving it to a clock from one of my other devices typically, but I had it out last night and was showing it to someone, and realized that short of beatmatching by ear, I didn't know how to sync it up w…
Seeing how such a significant feature has been added on to the device so quickly, is it safe to assume that the LXR will be able to make me breakfast and drive me to work within a month or two?
This thread really illustrates why open hardware is gre…
Wow. Just got around to trying this out. Amazing - this adds so much to an already great device. I'm getting some crazy sounds out of this...
Would it be realistic to hope that the LXR will eventually be able to save individual voices, with the s…
Julian's idea would mean that the current onscreen repeat/next system wouldn't work anymore, since each pattern could be followed by different patterns at different places in the sequence... So, maybe when shift is pressed, the sequence could be sh…
sounds good. another idea I had would be to use the pattern buttons to enter the desired sequence:
- hold shift
- selecting the already flashing step starts chain selection
- while holding shift enter the pattern sequence you like. for example 1, 1,…
Cool. Thanks for this.
Is it safe to assume that pretty much all the button handling code for all buttons in all modes is in /front/avr/buttonhandler.c and .h? Should I be looking anywhere else?
Frank's case labels those voices as "CL/OP Hi Hat", which suggests that the left button is closed, and the right button is open. But all the kits that ship with the LXR have it set up the opposite way - left button is open and right is closed.
Not …
