Im not going to try to write up a totally impartial review of the Hyperion since its my own design and Im a little biased, but I figured Id post some details here for comparison. A 30 polypro Hyperion weighs 9.8 ounces with battery and without counterweight. I think the only lighter smart hoop is the Atomic 5/8. The design is unusual in that it takes a single removable battery, like the FutureHoop but without the big gap and wide outer connector. The LED strip runs through the connector and right up to either side of the battery, so the gap is about 1.5. Battery capacity is 30% less than a Helix, but since it doesnt need to stop to recharge you can keep running as long as youve got batteries. The controller board has two separate processors. The smaller is a Freescale MC9S08SH32 - an 8-bit, 20 MHz device comparable (but entirely unrelated) to the processor in the FutureHoop, Synth, or Helix. This secondary processor has the job of driving the WS2812B LED strip, and can take on some of the simpler processing tasks. The main processor is a Freescale MCF51JM128, a 32-bit Coldfire device with a maximum speed of about 50 MHz. Its several times more powerful than the processors in the Synth, Helix, and FutureHoop, but probably not as fast as the one in the Photon - though it doesnt have any of the software overhead of an Arduino-based system. The processor is a descendant of the 68000 series used on the Amiga and classic Macintosh computers. Theres a 9-axis motion and position sensor (with angular rate gyros, accelerometers, and magnetometers), an IR receiver for the remote controls (it comes with 2), an IR emitter to talk to other hoops at short range, a 16 MB NOR flash chip for pattern storage, a Li-ion charger (to charge the battery via USB, though its normally charged on a wall charger), a USB port (it shows up as a mass storage device and takes BMP files as patterns), and a Bluetooth radio for hoop-to-hoop linking and Android remote control. An unpopulated spot on the board is reserved for a MEMS microphone, but sound detection didnt work out well in testing.
