I was browsing on the internet latey and I found a cool RPI powerd project:
https://hackaday.io/project/16288-raspb ... controller
So I tried making one myself.
I started by figuring out how to make it very cheap. So I went to aliexpress and found all the parts that would be able to replace everything that Anthony (from the guide linked above) uses. However there where a lot of problems with the battery charger. I was going to use the TP4056 charger, which charges a battery at 5V at 1AMP. This seemd right to me at first, but later I found out that you should never charge a battery at a higher rate than its capacity. Sinds the capacity of my battery that I was going to use was 500Mah, there would be a "slight" overkill...
After a lot of research I found out that is was possible to change resistor 3 with a 2,2K resistor so the battery would be charged at 540Mah, which would be acceptable. So I orderd all the parts. After a week of waiting I realized that I didn't check if there was a 5V booster inside of the TP4056!!! This is as most of you know mandatory for the rpi to function.
So I went to the forums and asked around. Veterangamer helped me out and let me realize that a using a battery would be absurd sinds the controller will be pluged into a TV so you're wired anyway


So I completely changed my design and here is the result: It has a micro USB input for power and you can decide if you want to connect that to your tv's usb poort or a powerbank. I think that a female jack like this is easier to use than the hdmi to usb adapter thingy that is used in prerunnerseth's build.
I'm still thinking of putting a Tiny USB hub on the right side so I can have one USB female what makes it possible for me to use it as a computer. I als think I might install a status LED.
Please let me know what you think about this project.
