DPS3003 DIY Power Supply Assembled 2

DPS3003 DIY Portable Lab Power Supply

In this post, I will show my DIY portable power supply. The PSU uses the DPS3003 module. This module is rated for voltages from 0-32V and currents from 0-3A. You can get other models with higher or lower voltage/current ratings. The input voltage, however, must be in the range of 6-40V and your maximum output voltage is limited to your input voltage. In my case, the battery provides around 16V to the input so the output voltage can’t go higher than that.

DIY Power and Power Factor Meter

DIY Power and Power Factor Meter

In this post, I will show my DIY power/power factor meter. The module itself was bought(of course) I just put it in an enclosure and added some cables to make measurements easier. This way I have a handy and cheap tool for measuring the power and power factor of any device that I connect to it. This thing is no professional instrument with great accuracy but it’s good enough for doing some basic measurements.

TV RCA Image Output with Arduino featured image

Arduino TVout library Image Output

In this tutorial, you will learn how to output video from an Arduino and display it on a TV. Here we will specifically, see how to output an image. If you would like to know how to make the adapter or know more about the other functions available(outputting text, shapes, pixels) in the TVout library see this post.

TV RCA Output with Arduino

Arduino RCA Video Output to TV

In this tutorial, you will learn how to output video from an Arduino and display it on a TV. We will make a board/cable adapter that will connect the Arduino to the TV through the RCA input. Then we’ll look at some of the functions available to us in the TVout library and use them to output something to the screen.

MAX II CPLD USB Blaster Connection

MAX II CPLD Basic Getting Started Tutorial

This tutorial will cover the hardware and software setup for the MAX II CPLD. We will also make a simple design to upload to the CPLD. This little dev board can be picked up on eBay or Aliexpress for around 10 bucks(including the USB blaster). It’s cheap, easy and simple compared to some of the other FPGA dev boards. Despite that, I didn’t find a lot of tutorials and projects(compared to the Arduino stuff) with this board so I thought I’d make a tutorial.
