[NTLK] USBC Rechargeable MP2X00 Batttery

[Elias Basse]

Matthias,

That is interesting, I am kinda geeking out now!  I like to do projects
like this, impossible becomes possible when you have a team of people that
want the same goal.

Maybe we need to jump on the discord server one day and chat, not sure what
time differences look like for everyone but I am in Cajun Country over in
Louisiana USA about 45 miles from New Orleans.

Some ideas/observations from your input as well as research and other
random notes:

* ESP32 can do the SOCKS5 conversion, allowing modern HTTPS to be HTTP if
only for the short connection from the ESP to the newton via PPP acting as
a non-secure to secure proxy server.
* Since Jake designed a board, it will fit - So a win There!
* Power delivery is a fickle thing, I am learning its drawbacks, but I have
powered (Not sure charging a battery inside of the newt) the newt no
problem as you saw in your experiences with 5V.  I am experimenting with
BUC converters so small I need a microscope to solder leads, but I have one
that I can change a resistor on to make 7.2v @ 1.2A (both current and
voltage limited) on the way which fits the bill when powered via
USBPD capable adapter. Super Capacitors can do cool things now.
* Serial Data can be done for sure TTL/232 for internal comms, and a mode
which can be programmed into the ESP that will allow passthrough (I did a
lot of embedded dev, there are other RISC based chips that could even add a
linux vm running internally for you to VNC into if you need a modern
browser)  We could repack a VNC style connection in Newton Script to
accomplish this to make it feel like you are using the newton possibly
(Learning Newtonscript to add to the 20 or so other languages I dabble in).
* Micro SD Part, not really sure about how that would interface, but that
sounds like it would be awesome.  My thoughts would be if it can interface
with the ESP, we can just have it as a serial based file store with an
application that could cheat XMODEM to transfer files from/To and directory
list (Simple and worked since the dawn of time).
* Cost is always a factor, but it should be sub 100 USD in my opinion to be
able to pull this off.
* GPIO would be fun to play with, especially if it can interface with
NewtonScript, new applications could be developed to use this.

The Really Geeky stuff and some reflections:
* They re-released the Commodore as an FPGA, with HDMI and USB. Why Not the
newton?
* Making the newton thinner in a new case would be amazing, adding some
E-Paper style screens would also be amazing for  a Mini-Newt 2.0 style
project.
* The ESP32 has almost the same power as the Newton relating to clock
cycles and speed.
* All of this cool newton stuff started off with an e-bay newton and an
e-bay e-mate for me, gracious members of this list have helped along this
journey with support and some hardware to allow experimenting.

All the best,

Elias
