This JavaScript injects a splitter on the Shadertoy view page to make it easy to resize the view of the shader and the code editing area. I made a pull request to the unoffical Shadertoy plugin to include this feature.

Just run the script in your browser's console window on a Shadertoy view page. Double-click the splitter to revert the position, and right-click it to remove it.

Setting up Heltec Wireless Stick Lite v3 for Meshtastic

I picked up the Heltec Wireless Stick Lite v3 as it was the cheapest Meshtastic hardware I could find. The documentation was rather lacking and outdated, so after figuring it all out I decided to write it up here.

	// function BoolToStr(B: Boolean; UseBoolStrs: Boolean = False): string;
	Writeln('BoolToStr(??, True)'); // BoolToStr(??, True)
	WriteLn('True = ' + BoolToStr(True, True)); // True = True
	WriteLn('False = ' + BoolToStr(False, True)); // False = False
	Writeln('BoolToStr(??, False)'); // BoolToStr(??, False)
	WriteLn('True = ' + BoolToStr(True, False)); // True = -1
	WriteLn('False = ' + BoolToStr(False, False)); // False = 0

	// class function ToString(const Value: Boolean; UseBoolStrs:
	// TUseBoolStrs = TUseBoolStrs.False): string;
