Interesting stuff at the Exploratorium

I created this choker as a project to demonstrate the new MicroNova APA102-2020 LED strips. Photo by Yeti, edited by Batgirl These addressable LEDs are extremely small, less than 1/4 the size of a standard 5050 LED. This project was built using engineering sample standard MicroNova 99 LED / meter strips . The MicroNova strips we are selling have 198/meter - […]

3D printer Using Smartphone Light The creators claim this is the first of its kind, high-resolution portable 3D printer. Interesting idea. (Via Designboom) Tiny Picobug It is adorable and multi-modal - it is capable of flying, crawling and grabbing. (Via IEEE Spectrum) Illuminated Bluetooth Speaker A combination of white oak and LED-illuminated acrylic makes this […]

What we have today are not Fairly Expensive Tortillas or Fortunately Edible Theremins,  but Field-Effect Transistors. If you know what it is, I will leave you to explore: 1RFZ44N N-Channel FET $2.50 The IRFZ44N is a very powerful useful N-Channel FET, with only 0.0175ohms resistance pushing 20 amperes at 5V! FQP27P06 P-Channel FET $0.95 A […]

Mr. Tilden informs me that his experiments with 40 B.I.O.Bugs in the desert of Whitesands, New Mexico will be detailed in the May issue of Discover Magazine. I've seen some of his personal pics of the experiment, and it is indeed impressive photography. Keep an eye out for this issue!
