Make A Plastic Project Box
A plastic project box is nice to have to make your project look better. This has always been one of my weaknesses. I can make a really advanced circuit, but when it comes to package it, I have some kind of disability.
Luckily there are some tools out there for people like me.
Here are three methods of making a plastic project box for you circuit:
- 3D Printing
- Laser Cutting
- Modify Standard Boxes
USB Circuit Development Made Easy
Using a USB circuit is the most common method for communicating between devices and computers.
In the old days usually people used the parallel port or the serial port. But these ports are becoming more and more rare. And on laptops they are almost non-existent.
But all computers have USB ports.
Yeah, and USB stands for Universal Serial Bus just in case you didn’t know
LDR Circuit Diagram
This LDR circuit diagram shows how you can make a light/dark detector.
An LDR or “Light Dependent Resistor” is a resistor where the resistance decreases with the strength of the light.
Free Circuit Drawing Software: SchemeIt
Recently I have been using this free circuit drawing software from Digikey. It’s called SchemeIt.
If you need a simple and fast way to draw a schematic diagram, it’s the best. It’s browser-based so you don’t have to download anything.
You don’t have to register. But if you want you can register and save your designs.
What Is A Resistor And What Does It Do?
“What is a resistor?” she asked.
“It’s a component that resists the flow of current” I said.
“Hmm.. I don’t get it. What does it do to my circuit?” she asked.
“Well, it doesn’t actually do anything actively” I said.
PCB Design Rules
When you design a circuit board, you need to follow the PCB design rules of your manufacturer. These rules are the limits of the machine that makes the circuit boards.
The first time I looked at the rules I got really bummed out because it seemed so freakin’ complicated.
“Why can’t they just make my PCB???”
After a while I calmed down and had a look at what I was up against. And it wasn’t that bad after all
How Does A Capacitor Work?
Do you often wonder “how does a capacitor work”?
At least I asked myself that many times when I was younger. I never really liked the “physics explanation”. It states something like “a capacitor works by storing energy electrostatically in an electric field”. I don’t know about you, but that didn’t make me any wiser when I was starting out with electronics.
I like to answer the question of “how does a capacitor work?” by saying that a capacitor works like a tiny rechargeable battery with very very very low capacity.
The time it takes to discharge a capacitor is usually only a split second. And so is the time to recharge it.
How To Build A Circuit In 6 Steps
6 steps for how to build a circuit:
- Find a circuit diagram
- Draw the circuit diagram into Eagle
- Draw board layout in eagle
- Get your circuit board made
- Order components
- Solder components to your board
Arduino Yun Makes Wifi Projects Really Simple
The Arduino Team recently announced the new Arduino Yun! This is the newest device in the Arduino family and it is pretty cool!
This new device has a WiFi interface embedded on the board. It lets you easily connect your device to internet through WiFi.
This means are going to see lots of new cool devices!
Maybe a toilet that takes a picture and puts it online of people who don’t wash their hands after going to the toilet?
Or a pair of party-devices that let’s you compete on who’s having the most awesome party (based on noise level).
What is a Diode?
I’ve been asked a few times – what is a diode?
Well, a diode is an electronic component that conducts current in one direction and blocks current from running in the other direction.
