XRAD'S Electronic Designs

Yep Rad, I always liked that Alien's pinger device. I think there are some 3D prints for it. Got the sound working with the range, then my TFMini pooped out...not a very robust unit. First it lost the range between 6 and 10 m, then it lost part of the Tx Rx... anyway, another in the mail somewhere..

Nearly finished with the real working LIDAR. Going on my laser blaster pic rail. Here are some prelim pics:

XRAD'S EYE OF AGAMOTTO!

Over the last few weeks, I have been busy frankencoding C++ w/arduino IDE using libraries for neopixels, HalloWingMO, and music maker feather for my take on the Eye of Agamotto. Hardware includes neopixels, adafruit music maker , adafruit Hallowing, add on amp, touch sensors, g sensor, lipo charger, speaker, 3D prints, etc.... I admit that the center 'eye' is not green like the infinity stone, but is an 'eye' none the less.

Here is near final product. Three black push buttons: left: color 'hold' - will set all pixels to current color and hold as long as pressed, and random sound. Center: one touch power I/O . Right: Fade last color and random sound. Four brass pins(on front cover) for cap sensors wired to A2-5 = four different pixel effects and random sound trigger. Shake for sound and rainbow. Light sensor functional for iris (which worked out well because the light sensor is shielded from the neopix by the EYE design, so it's not always contracted). 20 sci-fi MP3 files play randomly without hesitation(a few 'real' Agamotto sounds thrown in as well). 2 sounds on start-up w/special neopix pattern. 1000mAh Lipo and 1A charger. Some weathering washes....still a little bit to go. Have to finish weathering and make the strap. Will post a vid soon..... it's pretty cool in action.

Latest version of final code can be had here:
