  • Play the guitar sloppily
  • Mess with my computer
    • I love a very old Macintosh; old System 7.0-7.6 and MacOS 8.0-9.2. I own an old PowerBook 540C, 190 and two G3 notebooks; System 7.5, MacOS 8.5 and 9.1 as CD-ROMs. The SheepShaver is very unstable, so I tried to read its code, but it was too difficult (x x);.
      • QEMU for PPC is very stable on the Linux box. MacOS 9.2.2 runs on my Linux. But the sound device doesn’t work yet.
      • Recently, I found out a branch of QEMU-PPC named “Screamer”. I succeeded in compiling it on my Linux box with ALSA, so MacOS 9.2.2 operates with sound. However, the emulation speed is slower than the original version. (Why?)
    • Tips for Linux OS and applications
      • Ubuntu
      • CentOS
      • Wine project
      • timeshift (backup application like TimeMachine on MacOSX)
    • Tips for FreeBSD
    • Tips for MacPorts
      • I tried to run gnome3-desktop on the MacOSX GUI system.
    • LiveSPICE (MS-Windows only, this software is very unique, so I am interested in it. But its development stopped in 2014. But it hasn’t been updated since 2014.)
    • Jetson(TM)

  • Mess with hardware
    • Hand made magnetic PickUp using the 3D printer
    • Customization of my fretlight(TM) guitar with Bluetooth 4.2 device (600 series) up to Bluetooth 5.0 (because of very unstable connection with PCs and smartphones)
    • Making of FPGA using the Time-Frequency Analysis
      • noise reduction on any sound device
      • virtual pickup system like a GP-10(TM) using piezo pickup as a source of guitar sounds

  • etc
    • Combined with LT-spice(XVII) and KiCAD
      • EAGLE is highly functional, but even the STANDARD version is a tough buy, it seems to be able to share it already in the list of spice-nodes, but can’t we create something like a wrapper?
