This is my Halloween costume for the year 2013. It’s been in the works for about a year and has taken quite a few man hours to create. The screen is 14 by 15 pixels, so, pretty low resolution but it can still do some fun things. It is physically flexible in all directions, although […]
I love LED and stars, and after saw another instructables about star constellation and some mood lighting that was very inspired and I decided I wanted to take that idea and want to create some mood lighting with some skies component such as stars, and cloud, for the bonus there will be some effect for […]
We are a generation that love sound and light – can’t do without them really. Our most preferred time of day is night, or what we would call evening. We are particularly well acquainted with technology; doesn’t hurt these days. Our prerequisite for everything is that it be ‘cool’. Put it all together and in […]
So if you are like this Lazy Old Geek, you have a lot of rechargeable batteries lying around. I wrote another Instructable with some battery tips. http://www.instructables.com/id/Rechargeable-Battery-Tips/ Amongst these batteries, I have a lot that no longer work or don’t work very well. So I decided to try to revive them. First step: If the […]
This example shows how to use the tone() command to generate a pitch that follows the values of an analog input Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect one terminal of your speaker to digital pin 9 through a 100 ohm resistor, and its other terminal to ground. Power […]
I could not find instructions on a good Arduino chess clock so instead I built my own which I will describe here. Step 1: Parts list Step 2: Prototyping The whole project can be split into these parts: 1. getting the circuit right 2. the program 3. the physical layout This step is optional since […]
This is a simple arduino based project that consists of a laser tripwire that, when triggered, will begin a countdown sequence on red, orange and green LEDs. I designed this to be an easy project for someone learning how arduinos work (like me). This is my first instructable so please bare with me 🙂 (I’ll […]
No longer will you have to pay hundreds of dollars for a heart rate monitor! The Smart Heart Monitor will be able to do all of your cardiac measuring needs for you! The Smart Heart Monitor measures the user’s heartbeat using an LED and a very sensitive photo-resistor attached to the user’s ear. A light […]
Egads! LED Goggles you can see through (surprisingly well, too)! They pulse subtly, making them so cold and dehumanizing. They were totally perfect for the character I was going after – Mr Freeze. It was my first time really playing with LEDs and Arduinos, so it was a good learning curve hugely aided by the […]
In this instructable, I’m going to show you how to make a simple circuit/code with an arduino, which will make an LED connected to it flash from off to on, with 1-second intervals, as shown below. This is a very easy, basic idea, however it leads to many more complicated codes and circuits. Attaching the […]
