Recently I purchased a Plextor PX-40TSi SCSI CD-ROM drive from eBay. It was described as being in “excellent” condition and unusually it came with all of the retail packaging, manual & accessories which was re-assuring.
This is because they are commonly found in older non-PC industrial, professional audio, electronic/RF and medical equipment which is still in use and valuable.
When I unboxed this unit, I quickly noticed the plastic around and on the eject button was noticeably worn. This drive has clearly had a lot of use. I plugged it in, pressed eject and the tray came out with a horrendous grinding noise. It was also apparent that it was full of dust, dirt and even quite a lot of hair. Yuck!
With the tragic 2019-nCov outbreak in China likely to leave me without the PCBs for my next project for quite a while – this has left tech-time a little aimless to say the least. What more can one do than spend some of that time to see if I can bring this thing back to life while we wait and hope for the best.
Opening up the drive found a number of issues that were correctible with some hard work.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
