I made this 3d printed high torque worm gearbox. It called also winch, hoist or crane. The gearbox uses a 775 12V 13000 RPM (100 Watt) brushed DC-motor which it has 0.074 Nm torque and 13000 rpm. This 3d printed gearbox had a gear ratio of 98:1. So the...
The goal of the Open Modular Electronics Bench is to provide a modular and easily extensible benchtop instrumentation system, in order to facilitate a community-driven ecosystem of instrument modules. Haphazard design choices will kill adoption of any...
I bought a bunch of Z80 parts on ebay for cheap ($10 plus shipping). The parts came on a PCB which had not yet been flow soldered. From the date codes of the parts it looks like it was stuffed sometime around 1999. All I had to do was straighten...
Introduction Hi dear hackday I hope you will be fine today. I am presenting a project about power generation with the movement of steps. It has 3 phases. First will be with piezoelectric, second will be with hand harvesting flash light that has dc gear...
Here is the Open Source laser cutterHardware:The entire machine is moved by low cost servo motors with a close-loop encoder feedback. mxl timing belt and printed sprockets are used for movement.The machines have a cutting size of 2'x3' for the...
Here is the Open face router. It is the first open source closed loop open face router.This machine is designed to be moved to its surface. Its primary focus is to cut on non-movable surfaces. It can easily be set up on the floor of a house for inlays...
The Arduino Bluetooth Smart Car has the function of Complete tracking, obstacle avoidance, infrared remote control and Bluetooth remote control. It is a MCU study and application development system base on Atmege328.The greatest feature is that you can...
The structureThe main structure of the desk bridge is made from 3/4" plywood; two side panels, the top shelf, and two corner gussets. An 8'x4' sheet from Menard's was more than enough material. At the joints of the sides, top, and corner gussets, composite...
The project has been scripted in MATLAB because of it's amazing matrix math functions and simply because I had it installed on my laptop.What I eventually would like to do is develop a SLAM (Simultaneous Localization and Mapping) algorithm to generate...
The multi-Function automatic move smart car uses an MCU development application system and a 4-wheel driver system,the core of which is arduino Atmega-328P.It can realize multifunction,such as tracking,obstacle avoidance,remote control and some other...
This was my initial synopsis of the desired serverServer Design PlanOverview/ScopeThe Server should serve as a multifunctional in house hub which is capable of, but not limited to, Network Traffic Management, Firewall/Proxy Services, Web Services, VPN...
