As I prepare to start adding peripherals to my Pi Bot, I wanted to be sure to get around the 700ma power budget the Pi has. After searching for a cheap battery powered USB hub and finding little, I decided to hack up a few cheap(ish) parts and make my own.
- USB Hub: $1.39
- 5000mAh Battery: $17.93
- DC-DC Converter: $2.76
Total: $22.08
The Battery Hack:
Step 1
Crack it open
Step 2:
Find POWER and GND
Step 3:
Wire it up
Step 4:
Make a small hole for wires and bring wires out
Step 5:
Solder the respective leads to the DC-DC converter.
Step 6:
Smile, then sit through my way too long of a video to make it into the HUB.
Hope all are well. :)
Notes:
- Regarding the error at the end of the video. Don't panic (that's what I did). I actually found out this had nothing to do with my hub, it had to do with plugging an iPhone into a Raspberry Pi.
- NOTE2: I realize I used the wrong "hearty," my brain has problems typing homonyms and parahomonyms. :P
