- Part ONE
- 4.3 inch display
- runs Raspberry Pi Os Bullseye (not optimal)
- cable connection work, everything works
- Puffin browser
- two speakers are coming out of the audio port
- built-in audio amplifier
- 3 volts from GPIO pins
- not overclocket, but strong headsink installed to do so
- fan power from GPIO pins
- GPIO pins have to be soldered on RPi zero 2 w, which is pretty easy, but takes time.
- voltage from keyboard from the GPIO pins
- battery pack with power switch integrated, 5 volts
- charge the battery via micro usb input
- charge while using it, unusual (but not with external powerbank)
- total costs 40 to 50 USD, maybe less
Part TWO
- Version two of the developement.
- screen stopped and burned.
- replaces screen by another one, for details see video.
- new speakers, second hand from laptop.
- Bluetooth receiver and amplifier
- activity light from GPIO (how?)
Part 3.
- We have reviewed part 3 before here:
- We studied these three parts of the instruction
- Ist not possible to build a better device with components which are easier to handle
- The case is very big, do we need it?
- Audio is compliated, is it necessary?
- Why not to choose a somple power bank as power source?
– Did the develper give up this instruction?
–
- Did we really learn something new from the instruction, exept from that it is possible to build a mini laptop from a Raspberry Pi zero 2 w?
- Could we not improve this setup? It uses partly old components from other devices.
- Will will do this as much as possible also.
How can we improve this device, write your suggestions in the comments below:
