What is Bitcoin Stuff All About?
Everywhere you turn, it seems there is a mention of crypto currency, or the most renowned of them, Bitcoin. Elon Musk joked that he was giving his mother crypto currency on Saturday Night Live, investors are debating if this new form of currency is going to last, and...
What Does Robotics Look Like in 2022?
Growing up we all had ideas of what the future would look like. The Jetsons got it right with the video calls but missed the mark with flying cars. Also Roomba’s aren’t quite the robotic maid we saw with Rosie that we all want (and need). Another childhood favorite...
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.
The beginning of a blog…
Most things have a beginning. Well, if one considers the vast expanse of the nonexistent, assuming it does not exist in some alternate dimension, there are many things that never had a beginning. But, this all hinges on the definition of "thing" which may well...
