The TPL5110's time interval is configured by the applying resistance between the
DELAY pin and GND. The correspondance between time interval and resistance is
given starting on page 12 of this document:

http://www.ti.com/lit/ds/symlink/tpl5110.pdf

The documentation contains lookup tables for common intervals between 100ms to
2h. This script can also be used to calculate values between 1s and 2h.

File transfer-over-Telnet. For when you have no other option.

There are probably better ways to do this.

This expects the server to drop you into a shell immediately upon connection.
It also expects the `openssl` tool to be available.

The file is transferred in small Base64-encoded chunks. After each chunk, a

I was playing around with dynamically compiling and loading protobuf files. This kind of works,
so I wanted to save it for later.

I guess what I would want it to do is create a container object representing the message and enum
descriptors that allows you to access them as normal attributes.

Alternatively you can have protoc output a .py file and then fuss around with importlib to load it.

These are some helper routines I wrote for drawing images for a dual-color
128x64 OLED display. The display has a 16-row strip of cyan pixels along the
top, followed by an unaddressable strip of black which is 2 pixels in height,
then the remaining 48 rows are yellow.

To make it easier to keep drawings in the correct aspect ratio, I preferred to
