This project aims to create a research-validated otoscope whose plans are available freely and openly. The goal price is approximately USD$3 in parts. The current price is approximately USD$5.
This design is based on current gold-standard designs of premium-brand otoscopes.
The original design and work is by the talented Frankie Talarico. The license is TAPR OHL where applicable.
For an alternative speculum holder (like the one used by Spengler), please see this folder here.
