Nixie tachometer with Bluetooth LE

Thanks to Jeff LaBundy for writing in to share this project! You can read more about the build on his blog here.

Nixietach II is a deluxe electronic tachometer built for my 1971 Ford LTD. Discretely mounted along the bottom of the vehicle’s dashboard, Nixietach II reports revolutions per minute (RPM) with a quantization error of only 0.03 RPM at 1,000 RPM. Flipping a switch allows the design to double as a precision dwell meter. Either measurement is shown on the design’s lustrous cold-cathode display, built from authentic Soviet-era Nixie tubes. A rear-facing USB port allows for logging data to a file and exposes a command-line interface for control of the device. The design supports four, six and eight cylinder engines and is enclosed in a sumptuous anodized aluminum frame with ABS plastic insets.

Its most practical feature, however, is its Bluetooth LE interface for streaming data to a mobile device in real time. Live RPM and dwell readings are reported to a mobile app developed by Adafruit, turning your phone into a wireless tachometer for easy tune-up work under the hood.
