PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
Start a new project merging several skills in one task. This is my tank track robot controlled by a Raspberry Pi using a webservice. You can control the robot over dynamic website with webcam view. The RSPI also provides RPI-Wireless-Hotspot, so it is possible to connect directly with your smartphone.
An Arduino-Micro communicates to the RSPI over I2C and controls 8 servos. Also a battery state monitor is implemented. I decide to use standard AA Accus for powering with 2 rows a 5x 1,2 volt. A step-up/ step-down switching voltage regulator guaranteed 5 volt supply despite low battery.

Updates:
03/12/18: Due to frequent questions: the servo is a MODELCRAFT BMS-410C. You can buy this in Europe at Conrad (https://www.conrad.de/de/modelcraft-standard-servo-bms-410c-analog-servo-getriebe-material-kunststoff-stecksystem-jr-404753.html). The servo is therefore interesting, because he has a receptacle for the axle in the rear housing insinde !
01/04/16: After a long break, I return to the project again. The Raspberry Pi 3B has now integrated Bluetooth and FiFi which means it has more performance and i can remove the "Ampere-eating" WiFi-Stick. Also checking the use of adressable digital servos or selfmade Digital2PWM-Adaptor for serial (BUS) connection. My intention is reducing the amount of cable to the arm.
07/07/15: Project goes on. Currently, the main problem is the power, respectively the…
