R/C Bismarck and a waterpump yet

thingiverse

Bismarck Battleship Model That will be a meter-long, Bluetooth-controlled model of the Bismarck battleship built by German naval forces in 1939. What are the planned features? - One-meter length - Good printability - At least one artillery piece should be turnable and shoot water - Bluetooth control with an Android smartphone - Easy-to-build electronics - Cheap as possible - Print it occasionally These are just bad weeks for this challenge. - Printer broke down - Car broke down - Son is ill - And so on Because of that, the work on this project has been stopped until I get my printer up and running again. Until yesterday, I still had some hope to get the project done right on time for the MakeItFloat challenge. What is finished so far? - Water pump - Hull (printable, internal support) - Not printable but modeled the upper part (bridge, artillery, and so on) without the cranes To Do - Easy electronics to rebuild at home - Overall control with HC-05 (or alike) Bluetooth SPP + ATMega - Write simple software for Android and ATMega or Arduino - Motor control with a simple MOSFET H-Bridge - Paddle control with a cheap servo motor - Upload layout, schematics for electronics (PCB) - Write Android and ATMega/Arduino code - Model carrier for electronics, motors, and some kind of airsoft BB bearing for the turning artillery - Make bridge (upper part) printable - Write tutorials/HowTo's (compile app for Android, compile ATMega code, build electronics with single ATMega or Arduino, tricks to get the print up and running) That's it so far. Since I've spent about 50 hours in my printer since last week and still won't get it to print reliably, and anything else I could imagine breaks as well, I can't tell when I will keep on this project. For anyone interested, I uploaded my project files as well. I wish any other competitor best luck! One additional note The parts for the water pump are in the RS Doc files. I created many iterations depending on the power of your motor. Actually, you need about 5,000+ rpm, and the more torque you have, the bigger the lower part can be.
