FD to EOS RF extension tube.  Using a 50mm as a macro is the only practical use of an FD lens.  Experiments showed the minimum focus distance becomes 80cm if the FD is 15mm beyond the EF flange distance.  Unfortunately, the FD becomes fixed focus because this makes its maximum focus distance the same as its minimum focus distance.  The 50mm is visually too similar to the 100mm to justify this idea.

Spirograph - totally useless, but easy to print & a way to use the lion kingdom's collection of useless dollar store pens.  Nowadays, a practical spirograph would be a phone app, but maybe there's value in being able to draw large format hard copies.  There could be a magnetic jig which stayed in place on the paper, inner & outer jigs, different sized jigs, anaglyphs.  Maybe there's a way a confuser could use a lion as a plotter, through a spirograph type device which directed the position of the pen but relied on animal power to move the pen.

  • Starship incense burner

    lion mclionhead2 days ago 0 comments

    Backflow incense has gained popularity in recent years.  It sort of defeats the purpose to have the smoke go down, but whatever.  It requires specially shaped backflow cones & a holder with a channel for the smoke.   Imagine backflow incense coming out the rear end of a starship.  

    The lion kingdom's original idea of an incense stick inside a starship never took off.  The trick is a clamp which keeps the stick in a vertical orientation.  The stick could then fit inside a starship enclosure or cutaway.

  • Shock mount for a tiny microphone

    The mane need is isolating a microphone from a truck.  It would be made of rubber bands.  This was a tensegrity structure which could do the job.  The mane problem is a longer lasting rubber band.

  • Shower curtain rings

    lion mclionhead05/19/2022 at 09:13 0 comments

    There's never a shower curtain ring salesman when you need one.  After decades of frustration with shower curtain rings coming undone, breaking, not being filled with helium, or not being Diane Sawyer ear rings, there's real momentum behind this idea.  As usual, the designs on the internet all suck.

    After years of struggles, the lion kingdom came up with the Dell Griffith Mark 1, a single piece printable shower curtain ring.  How long it lasts, whether it stays locked, are all to be determined.

    Printed a full set over 3 hours.  They also work as ear rings.

  • Microphone attachment for cheap headphones

    lion mclionhead05/18/2022 at 22:50 0 comments

    The indirect, bluetooth microphones built into modern headphones sound utterly terrible.  The mane reason is all blueth microphones are limited to the 20 year old standard, 8khz sample rate & lots of compression.  

    There's a rare example at 4:10 of all the most expensive headphone microphones.  Even without any singing or music, they all sound terrible or at least $400 instead of $500.

    The 1st problem is the microphone cable is going to be a 2nd cable.  Maybe it could be farstened to the speaker cable.

    Most boom microphones have a hole in the side of an earpiece.

    Top of the line pilot headsets have an extension under the earpiece.

  • Rectangular bed extension

    lion mclionhead09/09/2021 at 06:02 0 comments

    The idea came of extending the bed in the Y direction to 400mm.  It would require a longer track, longer belt, & longer hot plate in the Y direction only.  It would allow the lion kingdom's largest panels to be printed in 1 piece.  

    A rectangular expansion requires far less new parts, takes far less space & would be far more used than a square expansion, yet only square expansions are made.  The cheapest 400mm one costs as much as a new printer.

    It could be ground down to 400x235 to fit in an apartment, but that would throw away all the other parts required for the 400x400 upgrade.  The next idea is just finding a longer track, longer belt, & longer hot plate.  Ideally, the hot plate would be divided so the entire thing didn't have to be heated for every print.

  • Pop socket

    lion mclionhead08/06/2021 at 19:31 0 comments

    The lion kingdom has always believed the inventor of the pop socket has gotten over compensated through a very effective patent enforcement program.  By now, there's no reason such a simple thing should still be even $10 in fiat money.

    Lacking a desire to spend $10 to reverse engineer such a thing, there was finally a good profile shot of the mechanism.  It's basically 2 toilet plungers stacked.  A system of 2 curved profiles & 2 square profiles make the toilet plungers.  The curved parts bend & lock into an inside out & inside in position.  The square parts create a vertical offset required by the curved parts to lock into the inside out position & divide the height of the retracted position.

    The trick is TPU delaminates if bent across the laminations.  Something would have to be done to strengthen the laminations or it would have to be printed as a flower.  The only reason it locks into 2 positions is the tension propagated around the circle.  It wouldn't work with separate flower pedals.

  • Unheated bed

    lion mclionhead07/30/2021 at 06:31 0 comments

    The answer is yes.  You can print without heating the bed, if the apartment is already 93F & you have a grip bed.  It doesn't stick as well, but it costs less & it doesn't make the apartment hotter than it already is.
