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 […]
New Bundle: The Northern Lights!
Dave Hrynkiw
December 6, 2012
Ok, more like The Northern light. There's only one, but it creates lots of light!
We made the SB-Firefly as a ATtiny85-based blinky light / "chewing-gum & duct-tape problem solver", that is also Digispark compatible.
We made the Star Controller 3-watt RGB LED kit as an easy way to tame bright and power-hungry LEDs.
We put them together with a 3-day power supply and diffusing container, add a 10% savings, and TaDAAAH: The Northern Lights Bundle! And it's well documented too!
What do you get in the bundle?
- 60140 SB-Firefly kit
- 60160 Star Controller RGB 3-watt LED kit
- 52242 2.1mm barrel jack/plug pair
- 17020 3AA battery holder
- 0.1µF Capacitor
- 8025 diffusion container
- Double-sided tape
- 5-conductor wire
Start with our instructions to build a mobile blinky-dome of doom (mount it on your bicycle helmet - everybody will see you coming), or modify it. The SB-Firefly is programmable with the Arduino programming enviroment (with a suitable in-circuit programmer), so you can use the remaining 2 available I/O pins to blend it into your project!

Solar Pendulum of DOOOM blogged on MAKE
I love MAKE magazine. I always enjoy reading (then trying) the projects in each magazine. I was a bit disappointed in their last issue where they didn't cover the complete process to make gunpowder, but that's a minor complaint. I just noticed on their blog that they're talking about our Solar Pendulum kit and Christopher […]
