  That makes a lot of sense! I pulled from github and wanted to make sure I had the most recent version of the IDE and couldn't remember which save on send I had. Thanks for the great support. I can't wait to have the kids at STEM camp playing with these!

  So I was starting to have some problems uploading code. Code looked like it went over; but it wasn't changing. I ran the following code:

  >s = require("Storage")
  =function () { [native code] }
  >s.eraseAll()
  =undefined
  

  And then re-loaded my code over usb and no more memory errors. I am wondering if it is not cleaning itself out properly between loads with the newest version of the IDE (pulled from Git today)

  That definitely helped with ram usage:

  >process.memory()
  ={ "free": 833, "usage": 767, "total": 1600, "history": 7,
    "gc": 571, "gctime": 2.573 }
  

  I was able to load the unminimized code (it previously failed to load where different levels of minimization would load; so i've been using it to test. I still get a message:

  But the code is loaded and stored.

  Interesting...Saving the image to flash is definitely something that would be easy. I'm not sure if I want to build a custom image; since I would then have to keep parity with the official branch after I distribute them to the kids.

  I'll try that.

  Here is the response from my device on load:

  I'm using this ESP8266_4MB board with battery and oled screen . I am able to install my codebase with basic minification on, but get Low memory messages. I guess I will have to optimise a bit.

  I plan to give these out at my schools summer STEM camp. Bought in bulk we can get it to around $10 a student with a battery and 3d print the case. I am writing a comprehensive demo to show them what they can do. It also makes sure I understand the platform; so I can answer questions. I just picked up JavaScript recently (Fitbit Ionic Development), so I am still getting comfortable with the language. I'll attach my demo so far.

  Thanks! That seems to have done the trick!...I'm not sure how much more stuff I can stuff into it; but I should be able to finish a nice demo program that shows the capabilities of this board.

  I saw that...I was hoping for an example of saving an entire javascript program into storage and then loading it and executing it. Would I create a helper program to save the .js file as a really long string then onInit() read it back out and then somehow execute the string as Javascript?

  Edit: I think I'm on the same page as you now....I will try playing with that tonight.

  Excellent! Is there anyway you could link to the example? I did a little searching but didn't see how to write executable code using the .write() command

  So is there a way to get around the 10k source code size limit?
