A Hewlett Packard Infrared Signal Decoder
Several Hewlett Packard pocket calculators are able
to send printer output via Infra-Red (IR) signals to
a small portable printer. They use an HP-specific
transmission protocol which is also called “Red
Eye”. This protocol is different from the bette
r known IrDA protocol. This document gives a brief
overview of the format and describes hard- and softwa
re to build a decoder system for this protocol.
This system allows receiving the “Red Eye” signals
with a computer via a serial or an USB interface.
Lixie is an edge-lit acrylic display for any numeric information you can think of! Clocks, temperature displays, hit counters, and more. Always being a fan of the beautiful typography of a Nixie Tube, the Lixie is a modern spin!
The TAPR TICC is a two-channel timestamping counter with better than 60 picosecond resolution and less than 100 picosecond typical jitter. It has an Allan Deviation noise floor below 1x10-10 for a one second measurement.

White Rabbit provides sub-nanosecond accuracy and picoseconds precision of synchronization for large distributed systems. It also allows for deterministic and reliable data delivery.
White Rabbit allows you to precision time-tag measured data and lets you trigger data taking in large installations while at the same time using the same network to transmit data.
