05:04 PM Task #978 (Assigned): System Wiring
Formalize lengths, gauges, and organization of wiring for sensors and actuators. Signals should be transferred on the... Dan Shope
05:01 PM Task #976: Scoutfly Connectors
This looks like a good, fairly low cost solution. Routing power/gnd separately is no problem. Dan Shope
02:09 PM Task #976: Scoutfly Connectors
There are a lack of 40pin FFC connectors, the common sizes seem to be <= 30 pins. We can do 2 20-pin connectors to me... Kevin Woo
11:42 AM Task #976 (Fixed): Scoutfly Connectors
Find 40+pin FFC (flexible flat cable) connector and cable (4+" length)
Find as inexpensive as possible (<$5 ideal)

11:59 AM Task #974: Accessory Ball Bearing
Use bushing instead of bearing (overkill)
Low profile (3/8" thickness) flange not necessary, but is good if we hav...
Dan Shope
05:32 AM Task #974 (Fixed): Accessory Ball Bearing
Add block for ball bearing and choose part
Recommend 0.250" ID, plain vanilla ball bearing (read: cheap) or use simp...

* red, green, same as the FTDI's
* Add 1 more of each so that we can fully utilize those pnps

04:06 PM Task #969 (Fixed): Look for smaller ethernet connector
Current one takes up a significant amount of room on the board Kevin Woo
03:59 PM Task #968 (Fixed): Double-check Resistor Divider Values
Some may be reversed Kevin Woo
03:59 PM Task #967 (Fixed): Double-check IC Footprints
Some may be reversed Kevin Woo
