Tell us about yourself!
Well, from the pics attached, it seem IBM panel, you can look for part no i.e P/N ,for your model it is 03L5060
well in that case renewable solar energy can be explored, as the espduino can be powered by 9V battery as well

yes..thats great :) !!
Wire Wrapped Copper Ring
The Copper rings looks great and with weaved design, i hope its more resistant to heat too.
Hiwell, yes resistor rating is important, typically resistor with same wattage rating may have different ohmic value, so instead go with the ohmic value. Add 1k ohm resistor between the echo pin and GPIO as in above. (To know resistor is 1k, you can refer to colour coding chart or measure with multi-meter).Waiting for sensor is due to improper value at Echo pin.Let me know, if you face further trouble, if any.
The Engineering Crash Course (for Makers)
Nice instructible for getting started, it would be nice to include ever expanding new MCU in future.
Thats great :) and yes a step down dc-dc converter could serve your purpose for single power source.
Yes, i agree with you, but to keep cost down you can locate one from ebay, i got my one for only 12$ for 15.6 inch screen , further to keep cost down for controller board choose the one with only required ports, i.e many controllers boards are available with VGA, HDMI, DVI etc ports, but for connecting raspberry pi, only VGA port is sufficient.
I wld be happy to judge more of tech stuffs
