  • ARDUINO: Setting up a Gentoo development environment…

    if you’re reading this post, most likely you’re having issues with setting up Crossdev as mentioned on the arduino.cc site. i tried countless times to configure my system for AVR compiling that way, but it always failed compiling avr-libc and would never compile avr-g++ no matter how i applied the USE flags. in short, i…

  • Mellotronium revised…

    here’s an update on the new additions/approach to the Mellotronium. i’m attempting to redo the SD card routines once i get the functionality added. using the SD library just doesn’t work right when reading byte values at 8kHz. i’ve looked into the WaveHC library with the most success, but had to modify not to use…

  • Arduino: LFO Generator

    here’s a treat for anyone that’s into the audio side of arduino. it’s an 8-bit two-timer based LFO Generator using timer 0/2 on an ATMega328p. i’m only using timer0 for output in this code. i’ve started implementing the LFO code into my 8-bit melotronium where timer2 is dedicated for the audio output. in the larger…

  • Arduino: the 8-bit Mellotronium prototype

    i’ve been pretty Arduino obsessed over the past month. i got in my head this idea about building a midi-controlled digital sampler that uses SD cards for storage after thumbing through the Arduino Cookbook and have finally started to make some headway on the project. there were some major obstacle to overcome, unfortunately. the first…

  • Arduino: second verse, same as first… sort of

    well, not really. feeble attempt and making some sort of microprocessor controlled tempo clock, but a good exercise in the ATMEGA328s finicky behavior. don’t ask me what that squeal is. i think it comes from the way the input was wired up (mistaking the second sleeve as a synonym for ground) coupled with the PWM…

  • Arduino: Analog Aerials

    Essentially the oBITerator program with aerials instead of actual input signal. Of course, we’ve got to mix in the newly constructed PT2399 pedal. A little work needs to happen in the common-collector preamp in the delay pedal. I’ll be recalculating those values soon as well as switching out a couple of the ceramic caps. They…
