An automated Standalone String cutter. it uses a 12v barrel connector PSU, Arduino nano, 2x nema 17 stepper motors, 2x drv8825 drivers, a hm11 BLE module and a PCB to connect everything. The rest is 3d printed. Quarters are stacked on top of a razor blade and raised. string is fed from a stepper to…
Drone parachutes
A series of drone parachutes I designed, produced, and sold. Ranging from 36″ in diameter to 120″ in diameter with passive or active deployment up to a 70lb compressed spring that not only moved the parachute away from the drone but reduced the altitude needed to open.
Software
Some Windows programs I have made. Blackjack – https://github.com/krash999/blackjack KkroppSync – https://github.com/krash999/kkroppsync Mayday software – http://maydayboards.com/downloads/ Zeroset center calculator – https://github.com/krash999/zeroset Zeroset web based – Zeroset
Electronics Case
Design of a case to house electronics. 3d printed for initial testing. mold design and production with injection molding for large scale distribution.
Nova
A wireless long range single channel radio for manually deploying a drone parachute. I designed this radio to have a long lasting rechargeable battery, have a quick double tap deployment and, simplistic small exterior.
Mayday
Automated drone parachute deployment system. Detects if a drone is free falling or tumbling and deploys a parachute.
Keezer meter
Electronic monitor for a homebrew keezer. Keezer-meter11-8-2019I’m happy to say I have bought a new freezer to replace the broken keezer it is smaller and only holds 3 kegs instead of 4 but the overall outside dimensions are much better for the limited space in the garage. More importantly the freezer has been converted and…
HBS-346
A horizontal band saw restoration. Made in Taiwan in 1978, 4×6 band saw with 3/4HP motor. brand CI? Seems similar to duracraft 4×6 band saw. Worm is in good shape, gear is in bad shape and has been worn down, by the looks of it from years without grease. The paint is in very good…
Grain Mill
A hand crank grain mill converted to use a stepper motor. 3d printed hopper, motor mount and gears. Gears are attached to setscrew collars. nema23 motor. 24v laptop power supply with a 5 volt linear regulator to power the Arduino nano.
