Thanksgiving Update
Happy Thanksgiving! There is so much to be thankful for at Oklahoma Robotics. Our team is growing at a rapid rate and our laser table is back in action!
Exciting Times at Oklahoma Robotics
The homegrown company, founded by Nathan Parrow in 2012, came into being during an era that has seen the downfall of the ‘mom & pop’ business. However, Parrow’s brainchild has not only existed throughout this crucial time for small business owners, it has flourished.

Simple BFO Metal Detector – Improved Circuit Design
Dickson Charge Pump
a dramatic difference in speed on the scooter motor. It is basically a voltage tripler taking 12v and turning it into 36. This shows the potential efficiency of a Dickson Charge Pump.
That’s what friends are for.
an even simpler design that will reduce component count and cost, and will increase power efficiency. We are moving towards a simple elegant solution that will exceed all the design specifications and yield a unique and highly flexible solution for breadboard power supplies and beyond.
A uA saved is really hard earned…
The standby current at 6v input level is now only 1uA! My latest estimate of the quiescent current of the toggling/control system is ~50uA. I’ll refine my numbers as testing verifies them.
The Pan Tilt Zoom Story
Pan tilt zoom camera head. The story of an affordable and easily controllable pan tilt zoom camera head. From research and development to custom prototyping and final production of a better pan tilt zoom head.
Prototype circuit for toggling
Here is the toggling circuit I am working on as represented in the iCircuit iOS simulator. Here I have my 3.3v switching regulator (TPS62056DGS) represented by an op amp with a reference voltage at 1.3v. I am representing an input pin of a 3.3v microcontroller with the second op amp.
Power under control
Have you ever finished breadboarding a project and upon reviewing your work observed that a large portion of your breadboard space was being wasted by your voltage regulation system? Have you ever wanted to use switching regulation in a high efficiency low power project? I do all the time, and I started working on a solution to this problem not too long ago.
