Simple Ft245 USB Oscilloscope for the PC - If you are thinking about adding
a USB interface between your project and a PC, read on. Implementing USB is now easier
than you think. Eddy Insam will show you how. The USB (Universal Serial Bus) provides
a new way of interfacing low and medium speed peripherals to personal computers. That
old workhorse, the RS232 connector, is fast becoming obsolete, even becoming absent in
newly purchased PCs. ….(electronic schematic added 11/08) |

Simple MIDI interface Tester - Sometimes when experimenting with different
soundcards and MIDI interfaces it is useful to see if there is some data going in MIDI
interface. This can be easily tested with this adapter, which converts the midi
signals to visible light pulses. Just the circuit and plug it to the MIDI output of
your computer.... (added 4/05) |

Simple MIDI Tester - Sometimes when experimenting with different soundcards
and MIDI interfaces it is useful to see if there is some data going in MIDI interface.
This can be easily tested with this adapter, which converts the midi signals to
visible light pulses. Just the circuit and plug it to the MIDI output of your
computer. When computer sends any midi data out, you see the LED flashing. I found
this tester very useful in testing homebuilt soundcard MIDI interface.... (added 4/05)
