I wanted to add a 360K floppy drive to my raspberry pi, so I threw together a circuit using the popular WD37C65 controller IC together with a Tandom TM100-2A floppy drive, the same drive that would have been used in the original IBM PC. Using this I'm able to format, read, and write 360K floppy disks from a python program running on the raspberry pi. The same controller can also be connected to a 1.44MB 3.5" drive and rewrite high density disks. For more electronics projects, see smbaker.com

Ive recently purchased some Raspberry Pi 4 and wanted to use them in some projects. It runs hotter than my old Raspberry Pi 3. I spent some time evaluating the temperature under load and trying out various fans to see how much fan RPM is necessary to produce a noticeable reduction in CPU temperature. I ended up settling on a 4-pin fan from delta electronics that easily allows fan speed to be controller from the raspberry pi and RPM to be read back. This fan is only 7mm thick making it ideal for fitting inside a relatively tight raspberry pi case. The fan part number is ASB0305HP-00CP4 and I bought it for just under ten bucks from digikey (digikey part number 603-2070-ND). Being able to control the fan speed easily from the pi is a great feature, as most of the time you dont need a noisy screaming fan at 9500 rpm. Something as low as just 1500 rpm may do. Thats if you think you need a fan at all. For more electronics stuff, see http://www.smbaker.com/")
