ARM7 poised to replace 8 bit µC in coming years? Quote:Virtually all of my work goes underwater and has to run forever (or nearly so) on batteries,
This is interesting. What sort of projects are these??
I made an atmega168 board...

[Slightly OT] Way to go, Colin! It's a great article!
Colin, you are famous...
But no reference to AVRFreaks.net
The best AVR resource there is :)

24V as power Maybe 2 or 3 of the 7805's could be used?
Can you parallel these things?
I run some AVR projects using 7805's hooked to 19v solar panels...but the current draw is only like 200ma...

24V as power A 7805 and a big heatsink will work fine :)
Not super efficient but super cheap.
The 7805 is about .35
And just scrounge a heatsink out of
some old junked device.
In fact...many...
ARM7 poised to replace 8 bit µC in coming years? I just ordered some LPC2119 arm stamps and a little dev board.
The stuff was cheap....but I also ordered Atmega128 stamps and dev board :)
Will comment more on the arm after I try...

Newbie: Help me pick a project, T.I.A. The sound recorder does sound the hardest.:)
An extremely easy to build project for an AVR is an electronic lock or coded switch system.
You use one input port connected to a...

ISP Programmer for ATmega16 Buttload + the 20$ butterfly is a marvel!
Dean is a genius and we will see great things from him
I am sure :)
I wish I was half as good at this stuff as Dean.
(I might be half as...

There is an interesting ARM dev board at Mikroelektronika. 150$ I never saw so many buttons and LEDs! I love the looks of it :)

I just wish there were some cheap 40-pin arm chips so you could experiment without having to solder sm stuff.
