Arduino controlled motorized Solder Paste Dispenser

Zapta shares his design files of his Arduino motorized solder paste dispenser for SMT soldering. This is a motorized solder paste dispenser for soldering SMT boards that was inspired by this thing http://www.thingiverse.com/thing:384680. The home directory of this project is on github here https://github.com/zapta/misc/tree/master/paste_injector and it include hardware and firmware design of a compatible controller board that is Arduino compatible (it looks to the Arduino IDE as an Arduino Pro Mini). Schematic:https://github.com/zapta/misc/raw/master/paste_injector/eagle/paste_injector_schematic.pdf BOM:https://github.com/zapta/misc/blob/master/paste_injector/eagle/paste_injector_bom.csv EEVBLOG discussion: http://www.eevblog.com/forum/reviews/solder-pasteflux-manual-syringe-applicator/150/ I printed successfully using both PLA and ABS and standard slicing parameters (3 layer shells, 20% infill).

Arduino capacitance meter

Electro-Labs’ DIY capacitance meter can measure capacitors rated from picofarads to millifarads. The circuit is based on Atmega328P and is Arduino IDE compatible. The capacitance is computed by measuring the capacitor charging time and is displayed on a Nokia 5110 LCD. The main component of the circuit is Atmega328P microcontroller (MCU) and it runs at 16MHz. RESET, MOSI, MISO, SCK, RX, TX, 5V and GND pins are extended to the connectors from J4 to J11 to let the user use an Arduino or an AVR programmer to program the microcontroller in ICSP mode. MCU reset button, a general purpose button

Arduino controlled low-cost robotic arm

Induatrial robotic arms are quite expensive. Dan Royer is building an Arduino-controlled open-source robotic arm affordable to the DIY makers community. Industrial arms starts at $10k each and go up from there. With low cost hardware everywhere now, I see a market opportunity for low cost arms to serve small industry. I’d like to drive the cost down by making an arm that others can tinker with, improve on, and build community around. I’d like to see two arms assemble a third. Tell Elon Musk I need his rockets – lets put Marginally Clever robots to work building that lunar colony.
