Liminal Packing List (2/27/2010)
February 27th, 2010David is bringing:
- Liminal Surface (+ power cord, + ethernet cable (1 long 1 short) + power strip)
- MacBookPro (+ power cord + vga adapter)
- Metric Halo Mobile I/O (+ firewire cable + power supply)
- Headphones for testing
- Wireless Cameras (+ wireless receivers + rca cables + power supplies)
- 1 Firewire Video Converter box (+ firewire cable)
- Tools for construction / debugging (1 solder station, solder, multitester, multitool, small screwdrivers, wire strippers, black tape)
- 3 RJ45 couplers (1 like the ones we’re using, 2 black slightly small but might work as temp replacements)
- 2 replacement inside table RGB leds + 2 replacement drivers boards
- Liminal Gadgets (7 photoresistor gadgets, 2 switch gadgets, 1 rotary solenoid gadget (needs rewiring), 2 xy joysticks, 1 turntable gadget, 1 squatting stian man gadget)
- Liminal cutouts (2 standing trees, 1 biplane, 2 acrylic stian heads, 1 neuron)
- 4 laser pointers
- Table Setting gadgets (turkish finger cymbals, cymbal holders, tuned aluminum rods, rod holders)
Ali is bringing:
- Liminal Surface (+ power cord, + ethernet cable (1 long 1 short) + power strip)
- MacBookPro (+ power cord + vga adapter)
- Audio interface (+ firewire cable + power supply)
- Liminal gadgets (whatever you got – photosensors, rotary solenoids (we’ll rewire), 7x striker)
- Liminal testing supplies (whatever debugging tools you’ve got – though I’ve already got a multitester)
- Tools – perhaps a fine tip for the soldering iron – I’ve got a standard tip – the station is a weller digital.
- PCB5s for David’s table + parts
- Concert attire (I brought all black)

New Block Diagram for PCB5 connectivity
February 3rd, 2010Corrected version of the block-diagram accounting for the fact that the two copies of PCB5 are identical (!) and therefore require analogous number.
This zip file includes the OmniGraffle file, a PDF and the above jpeg.

More Notes on Liminal-PCB5-Alpha-1 [with colin]
January 16th, 2010(Jan 15, 2010 – 11pm – David): I just made a complete pass through every connection on the boards. Here are the very few things I found.
DO SOMETHING ABOUT:
• The traces coming from PWM_12V_1 vary in size. Pins 1 and 2 (going to GRID_1 and GRID_2) are nice and thick. The traces going to 3, 4, and 5 start wide but get shorter along the way.
• The traces coming from PWM_12V_2 vary in size. Pins 1 and 2 (going to GRID_9 and GRID_10) are smaller than the rest (which are nice and thick).
PERHAPS DO SOMETHING ABOUT:
• On the ANALOG-TO-GLUION connector pin 1 and 19 (both GND_AN) are connected and 2 and 20 (both 5.0V) are connected. I don’t think they need to be (they are duplications) so those traces could be removed if it makes any difference.
• Similarly, the V3.3 on each of the PWM_3.3V_1-3 connectors are connected and needn’t be. We’re not using those pins for anything (we’re just keeping the cable layout from another source).
INFORMATIONAL:
• It was perhaps a little strange that we didn’t keep the order of analog wires consistent between the grid points (A00, GND, 5V) and the mixed megaports (A14, 5V, GND). We’ll just have to be careful when we wire the mixed megaport gadgets.
QUESTON:
• Just to double check that the GND_PS’s are all connected via the ground plate – I’m not sure how to toggle on that view in Eagle so they just look like unattached pins…
