Amiga Floppy Reader

For years I have wanted to be able to read some of my old, non-PC, floppy disks. A few years back I decided it was time I made a start (see posts here). The initial idea was to use an Arduino, with a PIC32MX as a fallback, connecting it to an external Amiga floppy drive …

STM32 Amiga Floppy

STM32 Amiga Floppy

I wrote in my previous post about alternative solutions instead of the Arduino. The set-up worked, sort of. The Arduino Uno was connected to the Amiga floppy drive, it was kicking out an index pulse and control was working. However the data signal when I looked at it on a scope seemed to be odd. It appeared …

Connect an external Amiga floppy drive, via a Arduino, to a USB port on a Mac. Sounds simple doesn’t it? Before you say yes, take a look at my previous posts, anything but simple. As mentioned previously there are existing projects that claim to be working at reading data including: Amiga Floppy Reader (AFR) by Marco …

Finding your position outdoors on a device is easy with GPS but indoors is another matter. I have some potential projects that might need indoor positioning so I have started researching and testing the subject. There are several ways to calculate indoor position and technologies including: Visible Light Communication (VLC); Bluetooth; WiFi; Ultra Wide Band …

Amiga USB Floppy

Amiga USB Floppy

I have now dropped all previous hardware (i.e. Arduino, LoRaWAN, Raspberry Pi, etc.) projects. Few seem to be progressing, most have been surpassed and so decision made to drop them all. I am starting just one new one. There are a stack of old Amiga floppy disks that go with my trusty old Commodore Amiga …

Getting into LoRaWAN

Getting into LoRaWAN

LoRa seems to be getting everywhere and I recently found I needed to remotely monitor some items. Nothing major, temperature, light level and possibly a few switches. There would be more to these units which will record locally and where possible relay via the internet. Some units have no or limited internet access and thus …
