Drawing Korean glyphs
A problem I see is resolution.  On a typical cheap'n'cheerful LCD (designed for ASCII in English) the individual character arrays (8x8, if you're lucky, 5x8 if you're not)...

Getting high AC Voltage, is it okay to power my oscilloscope?
If your location is powered off of two phases, check your neutral line - it might be disconnected.   See if anything run off the other phase is at very low voltage at the...

Fast AC voltage fault detector
In this particular case, I think the OP was using LEDs as an example of an output.  They may indeed have something much faster to hook up in mind.  S.

Fast AC voltage fault detector
If you're only detecting peak voltages, you have a frequency problem.  Given an AC line frequency of 50Hz then the peaks will only come along every 20ms - much longer than...

Connecting some pins together (mega88)
PS - Yes, there are sometimes applications for self-destructing chips.  e.g. when your spy plane crash-lands at a Chinese airport.  Most of these applications involve...

Connecting some pins together (mega88)
A few more suggestions:   1) Most board houses charge by the square inch.  Even one-time setup charges are going away.  If the board really is that small, it'll be...

Recovering "External 16MHz"-fused mega2560
As an aside, I got burned by this once.  Apparently even Atmel (now Microchip) isn't consistent about the XTAL pins.   gchapman wrote:XTAL2 then XTAL1, if need be, per a...
