This bionic hand it's structure is modelled after my hand so I could make a gel10 mold that would fit snug around it. I originally wanted to integrate some force feedback in the finger tips by using some small pushbuttons but that didn't turn out to well because the wires from the pushbuttons in combination with the gel10 mold caused to much friction in the joints of the fingers and the fingers had to push to hard to activate the pushbuttons. I'm now going to do some tests with currentsensors so I can messure the current going to the servo's and when the current goes above the normal level then the servo's would stop (that's the idea).  Components used: 4 × 15kg Servo'slink: https://www.banggood.com/MG995-High-Torgue-Mental-Gear-Analog-Servo-p-73885.html?rmmds=search&curwarehouse=CN 1 × 2.54mm Single Row Male Pin Header Strip For Arduinolink: https://www.banggood.com/10-Pcs-40-Pin-254mm-Single-Row-Male-Pin-Header-Strip-For-Arduino-p-918427.html?rmmds=search&curwarehouse=CN 2 × 9g servo'slink: https://www.banggood.com/TowerPro-SG90-Mini-Gear-Micro-Servo-9g-For-RC-Airplane-Helicopter-p-1009914.html?p=E01411629100201406T1&custlinkid=359550 1 × arduino nano V3link: https://www.banggood.com/Geekcreit-ATmega328P-Nano-V3-Module-Improved-Version-With-USB-Cable-Development-Board-For-Arduino-p-933647.html?p=E01411629100201406T1&custlinkid=255135 1 × DC-DC Step Down Adjustable Constant Voltage Current Power Supply Modulelink: https://www.banggood.com/LM2596-DC-DC-Verstellbar-Step-Down-Schaltregler-Power-Supply-Module-p-88252.html?p=E01411629100201406T1&custlinkid=255154 1 × 2S lipo 7.4Vlink: https://www.banggood.com/74V-2S-2000mAh-8C-Lipo-Battery-Compatible-for-Frsky-ACCST-Taranis-Q-X7-Transmitter-p-1249125.html?p=E01411629100201406T1&custlinkid=669244 2 × 5mm red LEDlink: https://www.banggood.com/Geekcreit-375pcs-3MM-5MM-LED-Light-Emitting-Diode-Beads-Resistance-Lights-Kits-Bulb-Lamp-p-1027601.html?p=E01411629100201406T1&custlinkid=669272 2 × pushbuttonlink: https://www.banggood.com/100pcs-Mini-Micro-Momentary-Tactile-Tact-Switch-Push-Button-DIP-P4-Normally-Open-p-917570.html?p=E01411629100201406T1&custlinkid=669260 2 × 200 ohm resistorlink: https://www.banggood.com/Wholesale-Geekcreit-600pcs-30-Kinds-Value-1-14W-Metal-Film-Resistor-Assorted-Kit-20pcs-Each-Value-p-53320.html?rmmds=search&curwarehouse=CN 3 × springs from old pens 1 × 1mm diameter steel rod or similar as shafts for the fingers 1 × nylon wire 1 × somewhat larger spring but less stiff as the springs from the pensthis spring brings the thumb back to it's original position.

All my latest projects and files can now be found here: https://bbprojects.technology I'm charging a small fee to cover the cost of the website, enjoy! I'm a maker. I design and create my own projects and build them from scratch. My favorite tools are my 3D-printer and laser cutter. I own a 3D printer since 2014 and still use it almost every day. I like to design 3D models and sometimes also animate it. Besides 3D printing and modeling I also like aviation a lot. I fly RC drones, helicopters and planes.
