This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900 . It’s the cheaper module now available in the market. The module is not simple to mount by an hobbyst, so we use the Breakboard TDGGSM_900 that we presented here . You can buy the GSM […]
There is a saying: “If all you have is a hammer, everything looks like a nail”. Well, when I see a display, I think of clocks 🙂 I will show you here how to easily make a simple digital clock by hacking Meggy Jr RGB. This is an Arduino-programmable device, featuring an 8×8 RGB LED […]
An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use switch to turn on one of several […]
This Arduino based project was designed to solve a recurring problem for my hearing impaired wife. Our laundry room is located remotely from our living area. If our laundry has finished washing and is not removed in time, it can sour or even get moldy. If our laundry has finished drying and is not removed […]
In the spirit of Earth Day, I have created a revolutionary new energy-saving lighting solution that is only ever on when your eyes are open. This is remarkably more efficient than normal lighting that remains on, even when your eyes are shut. Using my device, you get light when you need it, and darkness when you […]
You may be wondering, what is a PIP-Boy exactly? If you don’t know, a PIP-Boy is a tool used by the main character in the well-liked Fallout video game series for navigating, detecting radiation, storing/playing data, and managing inventory. As a huge enthusiast of the franchise, I chose to create my own version, but not […]
It’s time to release new updates for my first (ever) project with Arduino, “Color Light Music”. From artistic perspective, VU BarGraph style (IMHO) is the best one for spectral dynamic representation, and not much could be improved on this side. But this time, it cross my mind an another idea “Tears of Rainbow”. This blog about […]
So have you heard of sous vide? Well, this Lazy Old Geek (LOG) hasn’t or hadn’t. http://en.wikipedia.org/wiki/Sous-vide It’s French. So it’s kind of like boil-in-a-bag only you don’t boil it. The equipment can be rather expensive. http://www.sousvidesupreme.com/Shop_Online/SousVide_Supreme_Demi/Department.aspx?DeptID=3&&AdID=245&gclid=CN7PyM6uw7cCFWNp7AodomkA6g I thought that was rather expensive for a tender steak, so I decided to make my own. There […]
At long last I have managed to finish the Rainbow Word Clock! Once again, this one was inspired by Doug and his creations http://www.instructables.com/id/The-Wordclock-Grew-Up/ I have a fixation with RGB LED’s at the moment and I wanted to do something a little different. So, while it is still here (before my girlfriend nicks it!) I thought […]
So my last project was a Arduino wind chill machine. http://www.instructables.com/id/Arduino-Wind-Chill-Machine/ Naturally, this Lazy Old Geek wanted to add a weather vane (wind direction) to my weather station. Who cares, you may ask? Well, I am a Geek. Actually, wind direction has some importance. Here in the high desert, the winds are usually from the […]
