Before I start, I know that many people may think it’s unnecessary to have a spring coiling tool. You could use a lathe, buy premade springs for pennies, or even have custom springs made for fractions of a penny. HOWEVER, I have always loved the way spring coiling machines can accomplish what standard machine shop…
Train engine and track
I built this for my daughter to ride around the backyard. Its about 1:9 scale with the tracks 6.25″ apart. It uses a 700w 900kv motor direct driving one of the wheels. The track is made of .5″ square steel tubing with a .0625 wall thickness and the ties are 1×2 wood. It can tow…
SMT Parts flipper
I made this as a simple single purpose tool to aid in inverting parts that are upside down when assembling PCB’s by hand. The component are first dumped into the front tray, all right side up parts are then placed, the button front is then pressed to clam shell the back plate forward, both move…
Struggling with memory a “bit”
It’s March 20th 2023, I finally got around to soldering a PCB for the cable tester project. This was the first rev E board and was intended to be placed with the in progress pick and place machine but I broke the camera last week so I finished the parts by hand and reflowed it…
Mini Injection Molder
A manually operated injection molding machine to make low volume prototype injection molded parts. It uses a PID controller and solid state relay to send power to three nozzle heaters on an aluminum tube. Thermoplastic pellets are added to the tube and a lever attached to a stainless steel rod forces the then heated pellets…
Wire Tester
A wire/cable tester to make repeat cables and check continuity. RevC and up has RJ45 connections to make custom test cables easy and has pull-down resistors on pins to be able to check for connections on its own side in addition to across. Both buttons are held to save the configuration and will display a…
Headlamp
Thin, rechargeable, warm white headlamp with a high efficiency PWM driver and dimmer. -Features -Brightness adjusts to be consistent while battery voltage drops.-Softlatch single button operation with 5 brightness modes-Waterproof-SOS Long life beacon mode-7057 Aluminum
Power Tapper
A high torque electronic motor positioned perpendicular to a base plate for the propose of tapping holes. The motor is buoyant and free floating so as to be able to feed itself into and out of a hole when tapping it will stay perpendicular to the base plate but allow X and Y linear changes…
String Cutter
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…
