Recurse Center's LEDBot is awesome, though at present our cord situation is a little quirky (we have 3 cords).
- Large 5V Power Adapter - Goes to connector LED panel's barrel connector
- Small 5V Power Adapter - Connects to the Beaglebone Black's barrel connector
- Ethernet Cable - Connects to the Beaglebone Black's Ethernet port
- Consolidate power to a single line
- Move from ethernet to USB wifi adapter
We tried to use a single power adapter for the Beaglebone and the LEDs but ran into stability issues. If we put a capacitor on the power we could probably run a single line.
When we tried to connect via wifi we noticed:
- Lag when streaming OPC packets over the network
- Periodic trouble getting a DHCP lease
Connecting to the Beaglebone
The beaglebone lives at
ledbone.local on the Recurse Center network. If you can't find it here is another way you can conncet.
Find your IP Address with
ifconfig or sometimes
You should see something like
inet 10.0.0.100 netmask 0xffff0000 broadcast 10.0.255.255
Lets say our IP is 10.0.0.100
Use nmap to scan the local network
sudo apt-get install nmap
brew install nmap
Search the local network
sudo nmap -sP 10.0.0.0/24
Look for a result that contains
Texas Instruments like:
Nmap scan report for 10.0.0.102
Host is up (0.0048s latency).
MAC Address: 1C:BA:DE:AD:BE:EF (Texas Instruments)
