AVR chips have a couple of built-in ways to reduce power usage: "sleep" modes, and "Power Reduction Modes". Sleep modes stop the running program (which is the biggest power hog), waiting for an interrupt to wake it up, while Power Reduction Modes can be used any time (including while the processor is asleep).
My first etched board! Thanks, feurig!
It's a DC-DC step-up circuit that takes one or two AA batteries and spits out 5V on the other side.
I found the SECODER that I spoke about last meeting. It was in the bottom of the wrong junk box with old antenna equipment, not old telephone equipment. My mechanically inclined friends helped me get it working again.
I've written a web page describing my original application, Dial-a-Door.
I grabbed two of those 36 key keypad boards from Paul at the last dork bot, he grabbed them out of those POS boxes [with the big LCDs that he has posted info about]. I wanted to get them working with the Benito and also wanted work with i2c a little [as I have a bunch of these 8bit i2c i/o expanders]. The keypad has 20 i/o pins so the Benito cannot use it directly anyways.. though 12 bits of shift registering would probably be better... but either way, I wanted to use what I had + i2c.
Trying get 8 dorkbord+bonito's sets for gifting to the team members in China I'm working with on android.
Hoping to get Intel to pay for them....
For years now, I've been buying "bug zappers" - you know, they have a blacklight and a charged grid that attracts and electrocutes insects. Trouble is, they're cheaply made and the light fixture part always fails after about a year.
atmega328's now available. More flash! More SRAM!
Is there a was using the DorkBoard and the benito to output as a HID USB keyboard? I want my dorkboard to output keystrokes when it receives an interrupt on one(or more) of the pins.
I'm looking for a gentleman named Mark (if memory serves me) the I met at the beat off. Mark, if you're out there, please get in touch with me, firstname.lastname@example.org . By the way, your entry at the beat off was sweet.
To take advantage of the Benito's small size, I've zapped mine with a piece of software that, when plugged into a computer, causes the mouse to jump about randomly.
The size of the jitter can be adjusted by setting the "STEP" constant. 10 seems to be a pretty good number to make it seem like there's something wrong with your mouse. Anything larger, and it's pretty obvious that you're being messed with.
