Daft Punk Table Replica driver board reverse reconstruction.

I'm in love with the daft punk table: https://www.instructables.com/id/How-to-build-a-Daft-Punk-Table-Replica/?ALLSTEPSI'm actually making a wall hanging rather than a table because theres no room in my studio for another table.The author of that instructable didn't include the microcontroller program or a circuit for the driver board. From the description (and looking at another site) we can tell that it uses a a couple I2C port expanders connected to a transistor array. I have both the PFC port expander and the ULN2803A in my parts box, but I think it can be made cheaper, faster, and expandable.I want to ditch the I2C bus. Why? 1. Its slow (100 or 400 khz), not that more is needed, but what about bigger boards?2. Its bit intensive: each chip update requires a)start signal, b) address byte, c)port setting byte, d)stop signal. That's more than 8 bytes of bits per table update.3. Its expensive: the i2c bus needs 2 pullup resistors, and you have to route Vcc to them on the PCB. I2C peripherals are a bit pricey ($1+ for the PFC i2c port expander). You need a UC with hardware I2C, or write a I2C software routine, etc. 4. Its not expandable beyond the assigned number of I2C addresses. The PFC chips have a limited number of address selections (determined by the state of 3 pins). If all addresses have been used then a second I2C bus would have to be added.These goals can all be accomplished with a handy chip I learned about in lady ada's bike POV instructable, the 74HC(T)595. The 595 is a serial to parallel port expander with 8 output bits. The interface is a simple 3 line affair with serial data/clock lines and a latch that puts the data on the pins. Now the cool part: several can be connected end-to-end so that you can create a chain with hundreds of extra outputs. Bits can be clocked in at up to 20Mhz, so large or multiplexed grids are possible.Why its good:1. Its fast, up to 20 Mhz2. Simple interface - clock in only the bits needed then set the latch. 26 bits, <4 bytes per refresh.3. Its cheap: 0.33 per chip, easy 3 wire interface can be operated with microcontroller, PC parallel port, or even buttons.4. Massively expansion potential, multiple chips can be chained for a disgusting number of outputs.The circuit is pretty basic. It only includes those things needed for the graphics card : I/O expanders, transistor array, connection headers. Power supply and control unit are separate components. The 595 has a 'blank' pin, it seems to reset all the chips to a known state when pulled low. I wanted to make it available for a 'more complete' design, but I also included a jumper so that it can be manually disabled for use in simpler implementations.The 3d is just for fun: the PCB is mostly unrouted.Any comments or suggestions? Has anyone used the 595 before? I've ordered a few to play with, but have not yet used them.

300 Costume Making Help

I want to be King Leonidas from 300 for Halloween, but I don't want a cheap vinyl costume, or anything like that. I want actual metal..just having some trouble figuring out what all to do.Helmet - I've heard that aluminum roof flashing is easy to cut and work with..any ideas on how to make the skull cap/hair on top?(Mixing bowl suggested by Jessy)Cape - I'm going to take a deep red piece of cloth, cut up an old belt for the straps, and make some kind of clasp.Spear - Probably some conduit with a cardboard or possibly metal tip (how does one paint metal?)Sword - If aluminum flashing is easy to cut, ill cut out a blade, and then a plywood handle. JB weld the blade into the handle.loin cloth thing - I might take some brown shorts and bleach the legs...I think i'd be doing everyone a favor by not wearing a real oneArm protectors - Not really sure about these..any ideas?Shield - A Pizza panIf you have any suggestions on how to improve my ideas/answer questions, i'd really appreciate it.

A Good Crucible

Im new to the forge community and i need some advice. I built my first forge useing the charcoal and coffie can method. i melted about 20 or more cans so far and got about 86 grams of aluminum. The crucible i used was a soup that i burned through. I done that twice. While melting I got a lot of slag. Is that normal when melting cans? I also need a good crucible. What can i use for now and where can i get a good one later. I plan to make a propane forge in the near future so a few tips here would be helpfull as well. Any and all advice would be helpfull.

Cool airplane model made from scratch

Another interesting story from Africa about handmade goods. I'd love to get one of these.Phillip Isohe is a metal fabricator in the jua kali, non-traditional industrial sector, in Kenya. In his spare time he builds models of airplanes and buses. This seems to be an extension of what many of us did while growing up in Africa - building wire, or tin can, cars. What's most interesting is the excruciating attention to detail that he puts into each one. In fact, they each have motors with working lights, steering, engine and interiors. full story

Automated Single-Picture conversion for Anaglyph (3D glasses) except "Lasso3D"?

> http://en.wikipedia.org/wiki/Anaglyph_image//EDIT:I foundBas-Relief Demo ( http://www.3dphotopro.com/software.html ) which is great and allows most things i need in the demo version :-) It just needs a depth map, which I draw manualy by setting the brush transparency for different layer or drawing closer areas brighter.Still, I am open to any other program suggestions! :-)Hello,I am currently trying to convert a few photos, just so the people in front look further infront. I know how to do it manualy (cut objects infront, smudge hole, paste a bit further to the right, repeat layer for layer..., then i join the original image and the new one with AnaBuilder / AnnaBuilder / Zanag Z-Anaglyph) but I am looking for a program to convert the pictures, since its just taking long for not-so-creative work.Exept a bunch of totaly automated 2d-to-3d programs that work only on a limited number of images but are great to test anyway(xpounded.com Auto3D, Neurosys Anaglyph)I only found xpounded.com / Lasso3D (By Robert Spoons) where you roughly select the objects infront and the software does the rest.Its working good, but only for screen-sized resolutions, since no scrolling is possible :-( Thats a downside, since I want to print the images with a higher resolution.Does anyone know another (freeware?) tool or a simpler method in psp or gimp to convert images?xpounded.com / Lasso3D (By Robert Spoons)Thanks in advance for any help & ideas!-Marcus

Straight line art - what is the technical name?

I remember back in 2nd, 3rd, 4th, and I believe even 5th grade, when I was in a gifted program, we had to draw. We drew only straight lines, and when we did it right, it made a curve. We would get a paper with 2 lines, connected at a vertex, at a 90 degree angle. We would draw points every centimeter or so, and connect the points, far to close, far to close. (It's hard to explain.) I'm searching for it on the Internet, but I can't seem to find the right word. Does anyone know it? Thanks, and if it turns out all good, expect an Instructable on it mid- to late October.

R/C Sailboat

I want to make a R/C sailboat, so far I have 4x32x1/4 inch balsa wood planks and they should last me the entire project. This weekend I'm going to visit a hobby store and get: waterproof wood glue, waterproofer for the wood. Then go to target and get a rotary tool. The boat will be 3 inches tall with a 1 inch keel (keeps the boat from tipping) 5 inches wide and 15 inches tall. I will get a cheap multi directional R/C car and use the steering mechanism to move the rudder and the drive motor to turn the sail. Once I make the boat I'll fill the gaps with wood paste and water proof everything hopefuly with a silicon based sealant. Any tips or flaws with my plans, please see the attached sketch.

RBG: Shotgun Style

Yes, it is the only shotgun rubber band gun that I know of. It is based off of the Remington M870 and can be easily modified to be both be in an entry shotgun configuration, with tactical buttstock, or in a "Breeching weapon" configuration, with no buttstock. In the first picture, it is in the entry configuration. In the second picture, it is in the breeching configuration, but with the buttstock shown to show how it could be carried in a briefcase or something similar. There is no difference whatsoever between the two, other than the obvious difference in the buttstock, but less obvious, the breeching configuration has more mobility in the cocking hammer, so it works better. I am sorry for the lack of pictures of the internals, I will hopefully be posting them in the future.

Need help and ideas for graffiti

Inspired by the GRL i've thought of a cool idea for some graffiti:Overview:Using clear, or almost clear UV paint in 1 or 2 colors do a artsy stencil somewhere.then using a solar garden light, switch the LED for a UV and waterproof the wires and board somehow and find a way to attch so its hidden or out of reach.I would want to do this on the side of an overpass, perferably metal so i can use magnets to place things wherever i want. The panel would charge the singe rechargable AA (might mod to last longer) and then after it got dark enough the UV would show the work for a few hours untill it drained the battery.What i need help with:will paint like this ( http://www.clearneon.com ) be bright enough, any other suggestions for paint that won't be obvious unless its lit up.Will the UV LEDs be enough to see the art from a car driving below?any general mods or ideas to improve it?
