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 […]
I recently dug up my old RC transmitter and receiver and thought “How can i control my arduino with this?” so i powered on my scope to see what was going on at the receiver. Sure enough, it was sending out the standard PWM signal that servos use. Now I just needed something to control. What’s easy […]
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 […]
Once you’ve got a pushbutton working, you often want to do some action based on how many times the button is pushed. To do this, you need to know when the button changes state from off to on, and count how many times this change of state happens. This is called state change detection or edge detection. Circuit image developed […]
Low-voltage DC energy logging: sample voltage and current, correct offset, integrate over time, and separate uncertainty from billing-grade metering.
Just as you can concatenate Strings with other data objects using the StringAdditionOperator, you can also use the += operator and the cconcat() method to append things to Strings. The += operator and the concat() method work the same way, it’s just a matter of which style you prefer. The two examples below illustrate both, […]
I like drum machines. However they are not always the easiest to build. I wanted one that is: A. Simple, Yet Powerful-If it uses lots of components then it is too complicated B. Sound-It’s not a a drum machine if it “beeps” C. Easily Modifiable-If I can’t change stuff for improvement it is kind of […]
