Idea: Aerodynamic rubber bands
Not sure if I posted this already…
Aerodynamic rubber bands!!!! Come on!!! Cross section cut would probably look like a teardrop, with the fat (possibly flat) side inward to make it possible to shoot and give it some mass compared to a flat band…even though this is aerodynamically backwards. Ideally, I would think the fat part would face forward, like a wing, giving the front of the...
Shmuck Idea: S/PDIF Dejitter
So, people with crappy audio/video sources and receivers that use PLL’s for SPDIF clock recovery complain could get a nice clean signal.
Basically, would decode the SPDIF signal and re-encode with a more stable PLL, maybe hiding timing errors in data bits or preamble bits.
Idea: Confocal Seismograph
That’s all. Would be very sensitive of course. Aperture and overall size could/would be large for high bandwidth. Point of focus would be attached to the mass.
Software Idea: Auto echo cancel for audio...
Auto echo cancel app for audio/video recording for smart phones since audio recording kind of sucks right now. Would attempt to find and cancel worst of the room reverberation. Would be a deconvolution problem that would probably be handled on a server rather than the actual device, like voice recognition is these days.
Idea: LCD Aperture
An LCD aperture for cameras. Would be a gimmicky feature for inexpensive cameras. Would use an LCD rather than leaf based aperture. Would allow programmable shapes to be used for aperture, making pretty pictures in blurred images.
Could use it for an ND filter, too.
But mostly, could use it for coded aperture deconvolution for focal blur removal and depth extraction!
Bad Idea?: Single pixel DLP and photomultiplier...
Obvious. Use a cheap single photomultiplier (can find them for $25) and a DLP chip. A lens system would focus and image onto the DLP. Activating single pixels on the DLP would direct the light into the photomultiplier, giving a detector resolution equal to that of the DLP. Gain could be increased, at the expense of resolution, by activating multiple pixels on the DLP. Similar to a DLP television,...
