SCSI2SD external enclosure

thingiverse

This is an external enclosure for Michael McMaster's "SCSI2SD" circuit board. The SCSI2SD allows a standard micro SD card to be mounted as a virtual hard disk drive or floppy drive in a variety of classic computer and audio equipment, from the Commodore Amiga to Akai samplers. This board has allowed many people to resurrect otherwise obsolete equipment when their original drive fails, and also gives a new lease of life by allowing the easy interchange of files with modern equipment. Mostly the SCSI2SD is mounted internally and doesn't need an enclosure. However, I was motivated to make this design to allow me to connect it as an external device to the Roland VS2480, a hard disk multitrack recorder. This allows me to back up my recordings to an external computer, because the VS2480 has no USB interface. Michael's web shop sells an adapter from internal scsi to external 25-pin D type, which is a common connector for external SCSI devices. I designed this enclosure to take the combination of SCSI2SD and this adapter, to make a self-contained external scsi device. The SCSI2SD can be powered from the cable itself, depending on the host capabilities. However, for some applications it is necessary to use an external power supply. This may be done by plugging in a standard 5V micro-USB mobile phone supply to the enclosure. Alternatively there is space to drill through for another type of power connector, to connect to the 4-pin connector on the PCB. I designed the lid to include a scsi2sd logo inside the lid. This might seem a bit silly, but I intended to print with transparent PLA so that the internal bright orange LED could be seen from the outside. This LED is quite important because it informs you of the activity of the device as it flashes. The effect is that the subtle logo is internally illuminated, which is quite cool. If you want to print with opaque filament, then you will probably want to install an externally visable LED, for which there is a header on the PCB. I retained the PCB by the d-type screws, and also some hot glue onto the four support pads inside the enclosure. You may need to file out the slots for for the sd card and USB depending on your printer. The lid is retained by 4 small countersunk screws. Here is the main page for the SCSI2SD. You will find here a link to his manufacturer's website, Itead Studio, from where you can buy the PCB and the external d-type adapter required.http://www.codesrc.com/mediawiki/index.php?title=SCSI2SD
