==== The NSL Sceptre ====
Is basically a slight remix and cheaper version of the Elektor sceptre, it's functionally the same but we're bringing the costs down.

Install WinARM
[[http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/#winarm|WinARM it uses the ELF version, so the 2006 one]]
Programmers Notepad is also useful if you're IDE-less
[[http://www.pnotepad.org/|programmers notepad]]
Grab the 'Software' link from here [[http://www.elektor.com/magazines/2010/april/grasping-the-sceptre.1285403.lynkx|elektor]]
unzip and install it, install WinARM, add the utils\\bin and \\bin folder to your system path, open programmers notepad, open the Makefile and select Make All
