…Cho has been working on this project for a while and has gone through quite a prototypes. The latest Vincy Compound Bow Mark 3 is the best and fully functional. The Vincy Compound Bow Mark 3 is an improved version of Mark 2. The Mark 2 has a draw weight (the force required to hold the string stationary at full draw) of 6kg. According to the laws of Hong Kong, crossbows with draw weight of more than 6 kg are defined as arms. So all Cho’s previous designs has draw weight of no more than 6 kg. “But with draw weight of 6 kg, you can only shoot a chopstick about 6 meters,” says Cho.
Somehow he decided to power up the version 3 by adding extra fibraglass. The Vincy Compound Bow Mark 3 uses 4X 30/6/600 fiberglass and also features 3D printed drop-away arrow rest and adjustable cable tension device. he draw weight of the Vincy Compound Bow Mark 3 is 13kg, which can shoot things from 10 meters away.
…Cho calls himself a prototype maker. His previous projects include all kinds of home made hi-tech and low-tech stuff, such as 3D printed airsoft pistol shotgun, rail gun, ETG (Electrothermal Gun), crossblow, and the 3D printed compound bow….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
