Make a satellite dish Wi-Fi antenna for free internet How To: For example, the note C4 would be a frequency of Have any old school floppy drives lying around? Make a Spot Welder for Cheap! Therefore the floppy drive’s integrated motors are designed to step the read head through each of these 80 tracks. Rather, it is a spreadsheet-like set of instructions”.

Now that the embedded software both real time and FPGA is developed and the hardware wired, there is one final piece of the puzzle Mod a flashlight into an IR night vision light How To: Open a power supply labviea destroying a transformer How To: Finally, after the myRIO has finished playing a song, the read head must be return back to the starting position, by driving the motor back the remaining steps.

myRIO Student Projects

The next task is to change the motor direction when the floppy drive’s read head reaches the end or the start of the disk. This frequency value is then passed to the myRIOs on-board FPGA, which generates a digital pulse train used to control the floppy drive motors.

A bit of ancient history Each MIDI message includes channel number, the note to be played, note start time and note duration.

Make a sneaky, snake spy camera that records video How To: Using this information, I created a custom counters on the myRIO FPGA to ensure that the direction of the motor changed when it reached the start or end of the disk. Make a satellite dish Wi-Fi antenna for free internet How To: Please enable JavaScript to watch this video.

A MIDI file has up to 15 tracks of messages, each representing a separate instrument within the song e. This setup is then duplicated for how many drives you have to wire to the myRIO. Therefore the floppy drive’s integrated motors are designed to step the read head through each of these 80 tracks.

This project uses a myRIO embedded controller and four floppy disk drives. My name is James Willis. Hack a coin operated laundry machine All Features. These messages lagview then be turned into arrays of notes for each channel on the myRIOs realtime processor, which can then be passed down to the FPGA.

Rather, it is a spreadsheet-like set of instructions”. Now that the drives can me sent tloppy tonal frequency and produce a musical note, the next part of the project was to teach the myRIO some musical scores! Share Your Thoughts Click to share your thoughts. I’m a student from Cardiff University studying electrical and electronic engineering, currently on my placement year working as a Applications Engineer at National Instruments.

Batman Arrow How To: See the formula below. Therefore, two loop cycles is equal to one wave period. If your interested in doing a placement at NI, have a look at this page.

Hack your electricity meter How To: For example, the note C4 would be a frequency of The myRIO effectively plays the disk drives like musical instruments, by stepping the disk drive’s integrated motors at specific frequencies.

Make a Spot Welder for Cheap!

This was a very simple process that required no programming what so ever. The wiring requirements of myFloppyDriveQuartet are quite simple, because each drive needs just two digital lfoppy for step and one for direction. Have any old school floppy drives lying around?

More specifically, the disk is divided into 80 data tracks arranged in concentric circles, like the rings on a tree. This can be done quite simply using the custom counter that is already created.
