| RE: DIY Table Theta Question | 4 Relevance | 7 years ago | Bruce | Table Customization | |
| Welcome to our community! Though an unusual entrance route, we WAnt to support an open sharing of ideas. In answer to your question, in the Sisyphus coordinate System, positive Theta is CW. This is opposite of convention, where Theta = 0 is shown at 3 o'clock, and positive movement is CCW. The reason behind this "choice" WAs a simple error of mine during early development (where trials of multiple different mechanical and electrical configurations frequently flipped the directionality of the steppers). Since all my tracks were algorithmic and nonrepresentati ... | |||||
| creating new tracks | 4 Relevance | 7 years ago | davidp | Community Tracks | |
| I've just gotten my table, and I'm eager to create some new tracks. Here are a couple of first questions: 1) I can see that thr files are lists of coordinates. Each line is a pair of numbers "theta r". I am guessing that theta is the angle in radians and r is the radius (between 0 and 1). If successive lines in a file read "theta1 r1" and "theta2 r2", what is the *precise* path the table will draw in the sand between the two points? 2) How did people create the default thr files? My operating System is Linux, so I will not be interested in Mac or Windows tools. Any help/advice would be greatly appreciated, and I am looking forward to sharing whatever I create. Thanks very much, David | |||||

| I‘d love to get SSH access please. Is there a documented WAy to control the table via command line? That would be great for integrating the table into my smart home System... | |||||
| RE: Adding colored LEDs | 4 Relevance | 8 years ago | MicahR | Table Customization | |
| I just started messing with the RGBW neopixels last week so I don't have a lot of experience, but I found ALA when looking for existing implementations of neopixels, arduino and Rpi for network control. The fact that ALA had built animations WAs a huge plus, because I expected creating all the animations from scratch could suck up a lot of time. Here are the libraries and docs I used: ALA library Web-Controlled LED Animations After working on this, our embedded sys engineer is pushing me to experiment with direct RPi control and remove the added micro. ... | |||||

| ... through, made that slot just big enough to fit the LED cord through (using an exacto knife and a micro hacking method), patted down the velvet, replaced the LED hoop upside-down and plugged it in! It is GORGEOUS!!!! The whole thing took maybe 30 minutes, most of which WAs spent hacking away at the table. I am certain someone with tools and skills could do it faster and better, but the truth is that you cannot see the damage created unless you take the glass top and the ring off of the table. Two notes: 1) I have a 3' table and need to order one extensio ... | |||||

| ... files is ".thr"). Theta is in radians, and is in normalized length (0 - 1, where 0 is at the center, and 1 is at the farthest travel out). Unitizing the Rho value makes all tracks universal for any size table. All moves are from point to point, but instead of being linear as they would be in a Cartesian machine, they produce spiral arcs in this System. The simplest track file has just two points - an example being the "erase.thr" track: #erase.thr (start a line with # to make it a comment) #one vertex per line: Theta(real)<space>Rho(real from 0-1) ... | |||||
