  • SonicSurface: Phased-array for Levitation, Mid-air Tactile Feedback and Target Directional Speakers

    One of the best projects! Very interesting application for phased arrays (in 2D no less). The video kept my attention throughout. Totally excellent. Thank you.

  • Experiments on the Stefan-Boltzmann-law

    Very nice to see physics related projects with practical and inexpensive equipment. Thank you.

    Yes, I have seen the home page. All good. Usually I browse through the featured projects and found yours for the SB Law. Some years ago, I came across an IR spectrometer from the 1930-1940s or there abouts. The unit was about 6' wide, 3 feet high, 2 feet deep and had a table for notes etc (and a bunch of knobs to select wavelength etc and a chart recorder). Perkin Elmer? Anyway, if I recall, the incoming spectrum would illuminate a thermopile consisting of a single junction and that would connect to a transformer to increase the signal level. A beam chopper would repeatedly interrupt the light from the dispersive element and the Thermocouple would produce an AC signal that coupled to what was assumed to be a lock-in amplifier. I never really checked it out but I always marveled at i…

I never really checked it out but I always marveled at its sensitivity. The newer thermopiles appear to operate better than the older units and probably lower cost given the specialty transformer although the single thermocouple design would provide better spatial resolution. Again, thank you for the nice work.

  • Making a LED Aperture Science Handheld Portal Device

    WOW! The portal generator looks great and (unfortunately) works great! We were shocked and astounded with the audio-visual effects when the generator started up. Incredible. What a trip! Suan built one in the lab and heaven-help-us-all, it worked. He turned it on and the room began to warp. We saw three or four very intense worlds that appeared to be distinct and yet the images (?) were blended and blurred near the edges. We felt the pulsations from one gateway leading to a world near a black hole amidst dark matter where all knowledge was stored but unreachable. Another gateway revealed a horned world of intense heat and agony. Another to a world world at the far end of the universe. Suan stepped through but drop the portal device. He never looked back. As we stood watching the portals …

As we stood watching the portals shifted through many different worlds. How can we find Suan? Can we find him? What to do?

    Float Tank DIY!

    Nice work! Very interesting possibilities for psychology experiments.Nobel Laurette Richard Feynman experimented with SensoryDeprivation Tanks and hallucinationshttps://www.dmt-nexus.me/forum/default.aspx?g=posts&t=51786Other people suggest OBE, paranormal uses for sensory deprivation tankshttps://theghostdiaries.com/real-esp-experiments-inspired-stranger-things/

    Hi RyanMakeThe actual story comes from one of Feynman's "Surely you're Joking Mr. Feynman" books. Of course I can't vouch for all of the content on the cited website but the description looked similar to what I had read in the Feynman book several decades ago. It was a gift from my graduate advisor. Since that time, I've read examples of people trying to use Sensory Deprivation tanks for many experiments. Mike

  • Holy Heavens Above, Mike!! Ol' Petey here attempted to build one of these things but took your suggestion of curving space-time to the limits. He attempted to create a black hole in the lab to power this thing. He ended up rupturing the city water main and stretching himself to the shape of a noodle (massive tidal forces at the localized black hole). OMG!! Needless to say, the garden received ample water and a noodle head too. ... Great job Mike and nice introduction. Keep up the good work ...

  • There is indeed tremendous energy in the vacuum. But who can tap into it? Only an infinitesimal fraction has been extracted through the Casimir Effect. We attempted to use the Luminiferouslying Emitting Device to rend the cloak of aetherially forbidden realm and extract unlimited energy. Mad? Maybe. Yes we did attempt it but needed a larger disturber to rip it a new one. Bravo first step. Mind you, many a stout person speculates the aethereal virtual particles limit the speed of the rendering ray. Rip a hole in the cloak, swipe the vacuum energy and increase the speed of disturber ray as a side benefit. Oh bravo.I sure hope it doesn't fry the universe.

  • Got to thinking, maybe a portable disturber with high power Luminiferous Emitting Diodes would great great blaster-shredders in the eternal aether. Matey Pete made one as a scaled down version of Wobbler's version. We found a sulfurous stench near the aether void. No Pete. Bye Pete.

    Nice, very nice writeup. Makes the unit so much more real. Thx. One problem developed with my unit. We placed too large a disturber and it appears to have ripped the aether veil. We stepped through and the veil closed. Smells bad in there. Very bad. Dark and Dank. Bogs smell bad. Spirits shift in and out of view. Lord was that a burp?! Scratches. Thank heaven the guy left behind restarted the disturber and we jumped back to home! Maybe try a litter larger one next time.

  • Nice Job! For those people planning to test capacitors in a circuit (without removing them) consider purchasing a 'Blue Capacitor Tester' or 'Blue ESR Meter' available at anatekinstruments.com or amazon or ebay…. I have saved a number of high priced instruments (such as the HP54111d digital oscilloscope) using one. These will indicate a bad capacitor before the bulge and the capacitors can be tested without unsoldering. Just remember to shut down the power and discharge the caps.

  • Nice instructable.Please note that although not a 2000mW laser, the 380mW is more than sufficient to blind humans and PETs. Caution.
