Subject: [MakeLV] Shakespeare's Eyes
Message-ID: <CAJeZOyG75Vw0koh953syLOZzq02aEWqLqUn79Ok3jkGW3VHsPQ@mail.gmail.com>

Yesterday, we saw the giant Shakespeare head/face for the stagegroup... The
eyes don't light up!  (btw, the poster for the play is the image
attached.)  So, if we can come up with eyes that can be dropped in place it
would be awesome.

The eyes are 25" in circumference with 19-5/8" center to center.

The eyes they have are (fairly) solid plastic spheres that are too opaque
to light up even if we embedded LEDs in them.  I think the hard part will
be finding/making the spheres.  Lets assume we won't be able to find
suitable eyes in a craft store, how would we make them?

As far as the handle that moves the eyes, it is just a few items to pick up
at the hardware store.
2 Small Hinges (so the eyes don't rotate too oddly)
Wood Dowels (or should we use small wood slats so it is easy to attach the
hinges)
Spring (This allows you to pull the handle apart so you can cross the eyes)
Small hooks (To attach the spring to the dowels)
PVC Sleeve (for the spring/rod to travel in)
Threaded Rod & a Nut (this is so we can adjust the length of the bar, but
probably not really needed as long as the dowel is cut after the eyes are
installed)

The LED portion shouldn't be too hard, but might need some time to
experiment with diffusion.
I'm think at least Blue and Red as far as color.  More would just be
gravy.  Blinking?  Fade colors?  All possible, just need someone to spend
the time on the circuit.  Don't forget that someone needs to control the
eyes.  So, we really need to integrate the switch onto the handle.

The eyes will have about 4" of dowel (or wood slat) straight out the back
with a hinge on the end, then from hinge to hinge...  I should diagram
these, but for now here are 3 possibilities:
Hinge - Dowel - PVC sleave - Spring (attached to both dowels) - dowel
Hinge - Dowel - Threaded rod - Nut - PVC Sleeve - Dowel plug inside sleeve
- Spring - dowel - hinge
Hinge - Slat - Drawer slider - Slat - Hinge

*What kind of single axis hinge can you use with a dowel?  Bend it around
the dowel so the screws make a sort of X through it?
How could we make the spheres?  (Still, keep an eye out for them.)
What would make a good toggle switch?  Will need two colors.
We don't have a meeting this Thursday so we need to have everything ready
to go for the following Thursday.*

I believe I saw a TED talk where one of the guys involved in robotics at U
Penn shared that video along with some other things they are doing with
quadrotors.

Do the eyes NEED to be spheres?? What I'm getting at you may have better
luck finding something like a clear or translucent salad bowl or some such
in that size..

The only other thing that comes to mind is a laboratory flask (Florence
flask <http://en.wikipedia.org/wiki/Florence_flask>) that is round .... a
tad expensive ... but here is one: http://goo.gl/YY569

Small 110V lights [10-25W] will light up the eyes.
  [The bulbs for appliances are ideal]
  The plastic of the eyes is not opaque, but milky white.

1) Move the attachment point for the handle away from the 
    absolute rear of the eyes to near the top or bottom.

2) Cut holes for the lights at the current attachment point for the eyes.

3) Add eyebrows - they help a lot to convey expressions.

Clear isn't necessary.  They are going to be lit up from the inside, so...
semi-translucent?  We'll need to diffuse the light somewhat.

Actually, I was thinking even 1/2 a sphere would work.  I didn't measure
the degree of rotation, but I imagine it isn't too big.  The trick would be
to fit it onto their holder/bracket.  Their bracket is setup to hold a
sphere in place.  See the attached picture.

We can't use the current eyes.  For one thing, we don't want to mess with
what they are using so close to the performance.  Also, we put a flashlight
to the plastic and it didn't travel very far leading us to opine that the
plastic is too opaque without doing invasive drilling/scooping.

I think using LEDs would be better than bulbs so they can easily change
color.

It has eyebrows and whatnot.  Well, I think it does.  I forgot to take a
picture of the front.

Before giving up on the existing sphere, I would try a "grain of wheat"
12-16v bulb - brighter than your typical small flashlight and easy to
insert in a narrow hole that will not compromise the integrity of the ball
if it does not work.   Also, easy to power from a pair of 9V batteries or a
hobby transformer.

http://www.frys.com/product/2764833 for example.

they won't be that cheap.  An alternative might be some white beach

Keep in mind that 8" diameter would be perfect.  Anything more than 1"
difference in diameter, and I think it would be too big or too small.
 Well, bigger would work with a modified mechanism to hold them in place.

Have any of you played with the BeagleBone? I've been mildly interested in
it, especially as a Linux sysad I'd have a good start on many of the
skills. It is certainly more powerful than the Arudino, but I'm sure it had
its disadvantages. Price and a more complicated pin layout among them. What
else?

Here's a video Make Magazine created about it recently:

That looks like it would take me a long time to understand most of it. I
was going to poke some fun with them using an arduino, but it looks like
they programmed it directly with C instead of using the Arduino IDE so I
suppose that's more to Will's liking?

I liked the way they built the legs for the air frame. It looked as though
the pieces most likely to break were probably easily replaceable, as if the
whole arm and leg could quickly be swapped out with a spare.

I found some good stuff...

Those are 8" diameter light fixture replacements.  They have 4" holes with
the lip that usually hangs on screws.

Subject: [MakeLV] Replacement magnetic reed switch for bike computer?
Message-ID: <201203231313.17739.rhkramer@gmail.com>

Has anyone here ever picked out a magnetic reed switch to use as a replacement 
for a bike computer (i.e., electronic bike speedometer / odometer ...)?

We have two bike computers that are non-working because the reed switches have 
died.  (Both due to impact, they no longer switch, they're stuck in one 
position.  I've tried tapping them fairly hard to get them to operate again, 
but no luck.)

I'd like to buy an off the shelf reed switch and solder it in place of the 
original.

If anybody has done that, do you have a reed switch you'd recommend?

If not, I did a little bit of looking.  The reed switch in one of the speed 
sensors is about 1/2" long.  I found a reed switch that is 1/10" (diameter) 
by about 1/2", so it should physically fit.

Here is the switch I found:

SWITCH,MAG REED,SPST-NO 0.5A at 100VDC. JAMECO VALUEPRO MKA-14103-1015-R
 
http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_171872_-1

and a link to the data sheet:

http://www.jameco.com/Jameco/Products/ProdDS/171872.pdf

I can't copy and paste from that .pdf, so I'll mention a few things:

The battery operating the computer is (depending on the computer) either a 3.2 
or 1.6 volt button cell. (2032 or 2016).  Thus, I'm sure the voltage at the 
reed switch is no higher than that (it could be, I haven't measured it, but I 
doubt it is any higher).  So, I need contacts with low contact resistance.

I don't need high current capability.

I do want good resistance to mechanical shock.  This one is rated to withstand 
1 msec. shocks of up to 150 g, and sinusoidal vibration of 1 to 2000 Hz. at 
20 g.  Sounds likely to be tough enough.

Any comments, other suggestions?

Thanks!
Randy Kramer

Can't remember ... does "The Shack" still sell security system parts
.... pick up a door/window sensor and strip the reed switch from that.

Generally, reed switches are pretty interchangable, especially for low power applications like bike computers. The "Shack" used to sell bare switches.  I don't know if they still have them.  You could probably use one from a door or window alarm.  They may sell just the switch and matching magnet for expanding alarm systems.  Just look for one that has a rectangular box about an inch and a half long and about 3/8 inch square.  Also check to make sure that the reed switch isn't potted in the box (filled with epoxy).

Thanks!

Most of that kind of stuff at Radio Shack is now marked "web only", but I can 
probably find the same kind of thing at a place like Lowe's or Home Depot.

Thanks!  The bare (reed) switches are also marked web only on the Radio Shack 
site (and I stopped in to one that I passed yesterday running some 
errands--no luck.  Thinking about it today, I think they did have some reed 
relays, and I could disasseble one of those to get a switch.  All things to 
think about...

Hmm, I wonder if that Radio Shack that someone here has mentioned--over on the 
south side of Allentown somewhere, iirc--sounds like they cater to 
hobbyists--maybe they'd carry the bare reed switches.

If anyone here remembers which Radio Shack that is (even by approximate 
location), let me know, I'll give them a call.

Then one over near Ollies in East Allentown was probably the best RS I've
run into in the area so far.

Thanks, but if that's the one on the same street as Ollies (Catasauqua Road), 
it's gone.

I'm talking about Broadway and Tilghman where the harbor freight is. I
believe a Josh Earlies is in that general area also. I was there a few
months back.

Here's there phone number, according to google: 1-610-395-2155.

Just for anyone's information, I called that number and:
   * that is the correct number for that store
   * they don't carry reed switches (they do carry reed relays, which I'm 
fairly sure I could disassemble and use)
   * the girl I talked to insisted that they don't carry any more than any 
other Radio Shack--if the Internet says an item is web only, they won't have 
it

Next time I'm in that area, I'll probably stop in and check out their stock, 
just for future reference.

In the meantime, we found another bike computer at a yard sale--I'm going to 
take the speed sensor off it and put it on one of the better computers.

Thanks!
