SMT Equivalent of 1N4148 Diode? When I went looking for a replacement for the 1N4148, I found http://www.vishay.com/docs/88586/es1.pdf as a likely candidate.
DC-DC Converter - Off-the-Shelf or Roll-Your-Own...? Hadn't seen that one. Looks promising - except that I want to put a linear regulator following it, and it seems to be set at 5V.
Since I'm looking at a possible 6.5V output...

DC-DC Converter - Off-the-Shelf or Roll-Your-Own...? One of the irritating things I've been finding out about the off-the-shelf modules is the low switching frequency. The ones I've seen from CUI, Recom and Texas Instruments have...

[DIS] Tutorial Topic Ideas Please add my vote for a tutorial on adding USB to a project... perhaps combining LUFA with V-USB...? :)
What to do abot ungrounded outlets? If you're "not familiar" with household wiring, DO NOT try to figure it out yourself!
The neutral-bar is grounded at the breaker panel - but if that connection fails, you have...

Yup - I misread the datasheet. My bad... :oops:

Why would I want to toggle an input pin? If I'm reading the datasheet correctly, writing a 1 to the PINxn register engages the internal pull-up resistor on that particular pin if DDRxn is set to make that pin an input....

atoi() converts char to int... so it's no wonder you're getting an error. Try itoa() instead...

I use a GBC HeatSeal H212... picked it up at a local office-supply retailer for C$120.
