Connector choice and current-carrying capacity of wire
I'm fiddling around with a LED controller design - fairly typical.  It will use a TI tlc5926 LED driver (nice family) which provides a constant-current sink for each of 16...

Product wish - ddr3 based ramdisk pciE card
Way back when, Gigabyte came out with a cool product, the i-RAM. Was a pci card that took 4x ddr dimms to provide a 4G ramdisk, sata1 (yes, old 150) interface, and it only used...

Can ATmegaxXXU2 supply 3.3V to AT45DBxxx dataflash
I've been looking all over and can't really seem to find a definitive answer ... I would like to run an ATmega32U2 at 16MHz, which needs 5V. Also want to use an Atmel Dataflash,...

Sync between multiple identical devices
I'm in the midst if designing a small LED controller, and through sheer design brilliance (hah, blind luck) have a spare pin left over. I would like to add a feature to have a...

Recommendations for dual-feed switching regulator
I'm looking for an elegant way to power a project, something that doesn't take up too much board space ... It's an LED controller that's powered from 12V normally, but also has a...

Smallest FET for high-side LED power control
For controlling power to a LED string on the high side, one can use a P-ch fet. Pull the gate to GND, and it turns ON, powering the LEDs. Pull the gate to VCC and it turns off...

Options for monitoring generator output
Hi All - Looking for options for monitoring the output of a generator ... It puts out standard 240V with a center neutral for two legs of 120V. Would like to track both 120V...

Methods for controlling LEDs
Hi All - I'm looking at a project that will require control over at least 15 bi-color LEDs, common anode type probably. For flexibility, they will be treated as two sets of 15...

Chart of common footprint and family available ?
Is there a nice chart anywhere that shows all the common footprints families for AVR ? For example, AT90S8515 Mega8515 Mega162 Mega48 Mega88 Mega168 Mega8 Something to show which...

Need a 1-wire type protocol
Hi All - I need to control 9 bi-color LEDs as cheaply as possible. Actually, 9 groups of 9 bi-color LEDs, 81 total, but it should be a lot easier to handle them 9 at a time. I've...

Pin compatibility chart ?
Is there a complete compatibility chart anywhere ? I've poked around, and found a few "sort-of"s, but I would really like a complete chart of all the compatible AVRs out there....

Radio module choices
Hi All - I'm looking into using a set of radio transceivers at one point, but don't know much about them (yet). This would be for pretty simple serial transmission of data from a...
