There are several components of the BeBox, including 3D printed (filament), 3D printed (SLA), circuit boards, and random stuff picked up from Amazon:
The BlinkenPanel displays CPU usage on 16 LEDs shinging through the front. The project is shared on OSHPark. Other components needed for this are:
- Green Square LEDs - Part Number SSL-LX3353GD
- I2C GPIO expander - MCP23017-E/SP
- Resistors of various sort - 0805
- DC Fan 5V - any 30mm fan for a Raspberry Pi
The heart of the BeBox - a front panel with Blinkenlights. This is available on Shapeways or in the 3D files folder of this repository. Print with gray resin.
...Comes from Case Badges, have them make a 0.75" square domed badge of the images in the /Graphics folder of this repository
The case is designed for a Raspberry Pi 4, along with a dual microHDMI adapter board:
Screw bosses are sized for No. 4 screws.
Insert the LEDs in one side of the front panel. The anode (+) goes toward the middle. Bend the cathode (-) out. Fit the PCB with only the anodes of one side installed. Glue is recommended to hold the LEDs in place.
Install the other side of the LEDs, anode only.
Mount the PCB to the front panel with screws. Solder the anodes of the LEDs. Bend the cathode legs around the PCB to the other LED solder pads.
That's it! That's the easiest way to assemble this thing. Now write some python for the blinkenlights.
