Part 1: This series of videos is a recording of my 7 hour workshop teaching an introduction to Processing and Arduino. Since this is a class recording, there may be omissions, mistakes and other inconsistencies. I also run my workshops based upon the speed of the students and questions I receive. This workshop assumes you […]

For my children and technology class, we were challenged to make a product using a Lilypad Arduino. I am currently obsessed with the movie Frozen, so I decided to create something using one of the most iconic characters of the movie, Olaf. I used a blank, reusable grocery bag and created a picture of Olaf […]

Episode 3 of AndroidTec, Formed by members thamind (Jon) chaostic (Lewis) & Computer Whiz (Jim) and introducing GuyCothal, who discusses about the amazing abilities of Arduino micro controller boards and how they can be used with Androids! Jason also made a guest appearance!

The NXP Flyback SMPS Design Tool helps you design flyback power supplies using NXPs TEA1721, TEA1723, TEA1733 and TEA1738 family. The TEA1721(A, B, D, F) family, the TEA1723(A, B, D, F) family, the TEA1733(A, B, C, M, L) family and TEA1738(F, G, L) family are low cost Switched Mode Power Supply (SMPS) controller IC’s intended […]

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 […]

Talk Shield description: Japanese speech synthesizer LSI: Micro Talk ATS001B (Act Brain) Talk Shield specification:   Talk Shield pinout:   For more detail: Talk Shield

This is super simple but very useful if you are in a hurry or just like to do things yourself and on the off chance you didn’t know, this is about the easiest way to add mobile power to your Arduino. After looking at a number of battery power solutions for Arduino ranging from Lithium […]

Offered with fixed output voltages of 4.75 V, 5.0 V, 5.25 V and 5.5 V or an adjustable output voltage, the MIC2875 and MIC2876 2-MHz boost regulators from Micrel are capable of supplying up to 2 A of output current, while occupying just 122 mm2 of board space. These synchronous regulators also achieve efficiency of […]

Step 1: To Begin The basis for Groover’s axis was the two mini stepper motors from the DVD-RW drives. The motors drive the DVD head mechanism which either moved the laser cutting head, or the cutting table. My first starting point was to find a similar set of motors, and a reclaimed laser diode. However […]

Experience Flow and Control Electronics Background We are making the participants refuel a dead nuclear engine. We are making them handle dying and charged nuclear fuel rods. We want to give them an experience which will stay with them for long. Participants get multisensory input in auditory, visual and haptic forms. The fuel rod is […]
