Thanks for all the replies, Rylan. It's funny, Victoria Makerspace just moved to a bigger location as well. It's good to see the Maker movement growing! Keep up the good work.by Spelljammer - Polar Machines, SCARA, Robot Arms
I was thinking like this.by Spelljammer - Polar Machines, SCARA, Robot Arms
I love the design. You could try to make the thin flexible supports S shaped or some zigzag shape to add more length in a short distance to make them more flexible. You could also leave the supports off and use fishing line glued in place. Or you could use that flexible line for beading that looks like fishing line but is stretchable. I had an idea about returning to zero position. Any spring usby Spelljammer - Polar Machines, SCARA, Robot Arms
OK, I just tested in Linux Mint 13 and it works fine.by Spelljammer - Polar Machines, SCARA, Robot Arms
I ordered one of these through ebay http://www.ebay.com/itm/171145090006?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 It was so cheap, I wasn't worried about bypassing the capacitors inside it to make it DC coupled. But it had none. So, this USB sound card only costs $1.29 with free shipping and will work directly with the Peachy printer. I just tested sound output and it was fine.

@tag, thanks. Springs would be better. But I was envisioning something I already had. My wife has this flexible strands that are for beading, but it looks like fishing line but it is very rubbery. As far as the math, I haven't even thought about it. It would be good to know, so if you feel like tackling that But, even with that, I think the movement wont be linear towards the extremes and theby Spelljammer - Polar Machines, SCARA, Robot Arms
I too have been working on a single mirror design. This is just a mirror held balanced on a center fulcrum by 4 small rubber bands. There are 4 coils and 4 magnets. Each opposite coil and magnet work together. For instance, to move left, the X coil 1 and coil 2 energize, the magnets under each is set to the opposite polarity, the right one could be North pointing up and the left one pointing downby Spelljammer - Polar Machines, SCARA, Robot Arms
Thanks for the quick reply, James. I had a quick thought on mounting the thread to the front surface. If there are laser etched notches (small one at the top and bottom) on the first surface side of the mirror, the assembler could stretch the thread across the mirror surface with the thread in the notch at each end. Apply glue at those two spots and when it dries, use a knife or razor to cut thby Spelljammer - Polar Machines, SCARA, Robot Arms
Good point, Paul. If you notice my second drawing, I placed the pivot point at the mirror surface. It would involve etching a notch in the surface as deep as half the diameter of the thread or fishing line so that the pivot is exactly at the mirror surface. This could be easily done when cutting the acrylic mirrors with a laser cutter. There is a way to use solvent to take off the back of an acryby Spelljammer - Polar Machines, SCARA, Robot Arms
I wanted to mention the mirrors and their odd warping of edges on a a straight line. The mirrors are a second surface type which will eat up about 10% of the laser power going in and another 10% coming out and even more at more severe angles. So, two mirrors eat up about 40 to 60% of the laser's power. They also have a ghosted reflection artifact because some of the light bounces off the surface.by Spelljammer - Polar Machines, SCARA, Robot Arms
This was done in the late 90's in Portugal. Check out the pdf..some pics at the end. The part had to be cleaned up after, but much faster overall than machining the whole part from a block of steel. pdfby Spelljammer - General
Just some quick thoughts... The drip rate isn't constant and it doesn't need to be unless you want to print from the web or a device that doesn't or can't read the drip rate. My idea to keep the drip rate constant (if needed) is the same as a pet water dispenser. Basically, the water is up top in a closed system such as a 2 liter bottle. It is placed upside down in a reservoir and will maintainby Spelljammer - General
@Nahoj Not really, we are talking about 15 to 20 minutes per inch in a small container (1L about 4 inches deep).by Spelljammer - Polar Machines, SCARA, Robot Arms
Here is my first attempt at a design for a floating peachy. On a different subject, I'm actually leaning away from using mirrors at all. If a laser is hanging by a slight cantilevered connection, and two magnets are attached to the laser, then coils could use magnetic repulsion to push the laser into position, The natural hanging position would be less than my X,Y zero position. I would preloadby Spelljammer - Polar Machines, SCARA, Robot Arms
