- DIY digital stethoscope project for monitoring a cat's heartbeat.
- Author's cat 'Geuloush' has a minor heart abnormality requiring monthly monitoring.
- Manual heartbeat counting proved difficult due to cats' fast heart rates (140-220 bpm).
- Expensive vet equipment led to a DIY solution using a cheap stethoscope and USB microphone.
- Microphone attached to stethoscope tube to record heartbeat via Audacity on a Linux machine.
- Challenges included cat cooperation and purring masking the heartbeat sound.
- Successful recording and calculation of heartbeat (164 bpm) using audio software.
- Heartbeat measurements to be tracked in a LibreOffice Calc spreadsheet with a graph.
