Raspberry Pi PDA
Hey!
As I have mentioned in the last blog, I was preparing to make a small Raspberry Pi PDA (or Handheld PC) using my spare RPI 4B, and after about 20 days or so, I am 90% done building it, so the objective was to build a compact device to code (definitely not for hacking lol) and to take everywhere, so I listed some basic functions:
- Charge-free for at least 2 hours under full load (2 Amps)
- Fits in my hands
- Adequately cooled
- No external Keyboard or mouse unless necessary
- External USB 3.0 Ports
- External FULL-SIZED HDMI port
- System designed for purely ethical hacking (I Promise :3)
- Plays Sound
With all those function requirements, I went to work and made a components list (Please View Next Blog for Tutorial).
- Raspberry Pi 4B (x1)
- 32 GB SD Card (x1)
- 3.7v 3000mah Lithium Polymer Battery (Totals 6000mah) (x2)
- Charge/Boost Converter 2 in 1 Module (x1)
- Type-C Female Port (x2)
- Micro HDMI Male to HDMI Female Connector (x1)
- 18 AWG Wires (x4)
- Rectangular On-Off Switch (x1)
- 3.5 AUX Male to Positive/Negative Wire (x1)
- 8Ω 2W Wired Water-proof Speakers (x1)
- Rii Mini X1 Keyboard (x1)
- USB 3.0 2-port conjoined Female Port (x1)
Then, based on the size of the components, I modeled a case for it in Autodesk Fusion (Download Link of Model in TUTORIAL BLOG):
After creating the model, I bought the components, and the price was totaling about 150¥ (CNY) or about 21$ (USD), excluding the Raspberry Pi and the 32 Gigabyte MicroSD Card which I already have, then I pieced the components together and got it working without the case!
