Nice build for a Syringe Pump

I like the overall build on this project.  One thing I might do different is maybe cheaper steppers. https://www.drdflo.com/syringe 3D parts here https://hackaday.io/post/5681

Wow this is a fancy skittle sorter

This is a pretty fancy looknig sorter, impressive too (fast as well).  Uses 2 atiny’s to control it.  Would I build one…no way too much work involved in this build.  Still a nice build overall. M&Ms and Skittles Sorting Machine … Continue reading

Make a flaming R/C car

OK this is a bit more than I would do, but pretty niffty build if you want a flamethrower on your R/C car.  Maybe a future battlebot? I do like the use of a glow heater to start the flame. … Continue reading

Nice video on controlling a stepper with L293D and an Arduino

Nice video on using the two chips together to control a simple stepper motor.  This is great with smaller steppers, bigger ones need a bit more thought. http://www.instructables.com/id/Arduino-How-to-Control-a-Stepper-Motor-With-L293D-/

Build a quadcopter out of PVC

Well that definitely reduces the frame cost.  The author build the frame for a quad-copter out of PVC.  Everything else is standard stuff (so motors and controller are standard stuff. http://www.instructables.com/id/The-Ultimate-PVC-Quadcopter/?ALLSTEPS

Simple Arduino Servo Controller.

So if you have 4 servo based CNC and need to add some button/LED to it to control it, this would be a project for you. http://www.instructables.com/id/Simple-3-Button-Controller-for-a-4-Axis-Robot-Arm/
