Getting down to business, National Instruments’ general-purpose digitizer/oscilloscope offers a 1 giga-sample per second (GS/s) real-time sampling rate on two simultaneous channels and 20 GS/s Equivalent Time-Sampling (ETS). NI chose National Semiconductor’s dual-channel ADC08D1500 1.5 GS/s analog-to-digital converter (ADC) for the module because of its performance and features. When using only one channel, the NI unit uses the ADC’s built-in interleaving mode with autocalibration to double the real-time sample rate. Key specs for the ADC include 7.25 effective number of bits (ENOBs) at an input frequency of 748 MHz and a bit error rate (BER) of 10-18.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
