Glad to see I'm not the only one attempting this project.
I just submitted the files to my university for printing (Gotta utilize the library before I graduate!) Should be ready in a week or sooner.
Purchased parts:
McMaster-Carr: Total came to $48.36 Plus "applicable shipping charges" (whatever that means)
Digi-Key: Only purchased the potentiometer. I can add switches later. Total come to about $15 (again shipping is not specified but an "estimate" was provided)
Sparkfun: Omitted the wire since not adding buttons now. Total: $28.99 (finally a solid answer on price lol)
Tower Hobbies: Total: $9.38
So for these parts I am spending about $110 after shipping. (adding in about $9 for McMaster-Carr shipping.)
Heads up to everyone: The pricing in the instructions is a bit off.
I am not too worried about this as I am more in it for the hobby but others may be shocked.
Simple math of the parts list he gives will show a difference too.
Another note on parts. I didn't feel like doing too much research but it may be possible to get some parts locally. With my busy schedule i don't have that time but just a thought.
I'll try to keep updating as parts arrive. Can't wait to start the build!
