+## Controller Progress
+
+I can run tests now, pulling data back in raw 24-bit signed integers from the load cell amp, and counting single steps.

+
+I can save this / output it as a JSON object, and it should be trivial to get this data out to a database somewhere... just need to know how the object should be formatted / how the database should be connected to.
+
+## Controller Desires
+
+- cyclic loading
+- direct upload -> materiom (generic: databases) ... MQTT (and nodered)
+- https://cookbook.nodered.org/mqtt/ (and: https://cookbook.nodered.org/)

+## uSSM #3

 Theres a few new criteria that ussm-3 aims to achieve:
-- Manufactured only using simple shop tools, PLA 3d printers, and a standard bed size (24'x 24') laser cutter. 
+- Manufactured only using simple shop tools, PLA 3d printers, and a standard bed size (24'x 24') laser cutter.
 - Pulling force of around 600N
 
 In order to be laser cuttable, acryllic and delrin were the main two materials considered. Delrin was the go to option to avoid shattering.
