Re-Doing my Design for a circuit to control an invention using a Microchip PIC microcontroller chips.

In a previous article I described how I designed the circuitry to control functions of the asparagus harvester.  After bread boarding up a test circuit and doing some initial programming I decided a re-do was in order. I found I had a lot of unnecessary redundancy and I also decided to put the air regulation function on a separate chip from the main controller chip.  I did so because I want the air regulati ...

WEB-BASED CIRCUIT DESIGN & ANALYSIS

Microcontroller ( MCU ) circuits TINACloud supports a lot of PIC, AVR, 8051 and ARM microcontrollers; new MCUs are constantly being added. You can see and modify the program running in the processor and, of course, you can create your own code. There are two ways of providing the program for microcontrollers in TINACloud. You can use the binary code and debug file made by a standard compiler (e.g. MPLAB for ...

Making circuit boards in 20 seconds with DLP projector

Every Maker like me dream a PCB printer which can quickly and precisely convert our electronic idea into a psychical circuit board. I know there are plenty of project going on the subject. (see the end of the article) What I tried here is something different, quick and precise. If you have lots of electronic idea in your mind and most of them have a high probability of fail, the system must be quick and eas ...

Short circuit protection for (almost) any power supply

Step 1: Understanding the circuit The circuit is really easy to understand. A resistor of low value (the resistor value will be explained later) is connected in series with the output of the power supply. As current starts to flow through it, a small voltage drop will appear on it and we will use this voltage drop to determine whether the power supply out put is overloaded or short circuited. The "heart" of ...
