I have considered running Logo straight from SD card. It’s a matter of simply interpreting the commands from a file - just like the original Turtle.
Initially I thought it would be nicer to teach the child how it works to program something in the coding window, run it, see it do something in real life and then debug the program. In retrospect it’s way too much to ask of an 11 year old with no programming experience (yet). What is nice about the original Logo concept is to do things interactively - so saying “Forward 50” does it straight away. So my next goal is to set up wireless comms between TurtleBot and the PC so you could issue such commands over a “terminal”.
It will definately be cool to insert an SD card and see it run the program too - so I’ll definately do that (one day when there’s enough hours in the night!)
I currently have a technical problem someone here could perhaps help with…
I power the TurtleBot from a 4.8V battery pack connected to the 5V pin on the Fez Domino via a diode. I thought this would be OK because that line runs through a 3.3V regulator “downstream” for the processor. The lights come on, but it doesn’t seem to run the app. When I connect USB, I get the “connect” sound it starts running the program immediately. Do you think the problem is with power or with .Net MF wanting to be connected to the PC to run the program?
If I use the 12V input, I think I’ll need 6.2V at least because the 5V LDO regulator will drop 1.2V so I was trying to avoid that.
Can Fez Domino be powered from 4.8V NiMH? It it safe to 6V (Alkaline) on the 5V line as an alternative?
