DIY Cheap & Portable Power Supply Version 1.0 There are a lots of power supplies in market but those are too expensive for a Arduino Beginner or a Hobbyist. So I decided to make a Good Looking and Cheap power supply out of cheap modules. the power Supply must be handy as well as Powerful. So I started with making a voltmeter using 7107 IC (4- 7 Segment display Compatible). I created a circuit Diagram using EasEDA.com and created a Schematics and Then created a PCB design for the same and ordered my PCBs from jlcpcb.com because they provide best quality PCBs in the market. All the Schematics and PCB Design can be downloaded from www.robocircuits.com link to files – http://www.robocircuits.com/digital-voltmeter-without-arduino/ Then for making the Power Supply I printed a 3D Enclosure for the PS and get it printed by a local 3D printer. Then I grab some components 1. Voltmeter – http://www.robocircuits.com/digital-voltmeter-without-arduino/ 2. Buck Conveter – https://amzn.to/2RfWbcG…

9+COMPONENTS AND SUPPLIES Arduino Nano R3 × 1 Real Time Clock (RTC) × 1 Linear Regulator (7805) × 1 SparkFun LilyPad Rainbow LED (strip of 7 colors) × 1 NECESSARY TOOLS AND MACHINES Soldering iron (generic) APPS AND ONLINE SERVICES Arduino IDE ABOUT THIS PROJECT Ambient Lightning Real-Time Clock Aim I made this Clock because I have a addressable LED strip laying around and I want to use it. Then I saw my room doesn’t have a good Clock that matches its walls. So I Decided to make a Clock which can change its colors according to users mood or wall color. Making Process YouTube Video – https://youtu.be/BOfylZIl_ws I firstly took a 24 x 15 inch plywood board. Cut LED strip into pieces and paste them on the board Then After soldering them I cover the whole with a black chart paper Then paste a thermocoal sheet on top of it…
