+Hardware
+========
+
+Nice software doesn't do you much good if you don't have the hardware
+to control.  There are a number of quasi-open hardware solutions for
+building your own AFM (and other types of scanning probe microscopes).
+There's [a good list on opencircuits][opencircuits].  Interesting
+projects include:
+
+* Glenn Durden's [STM][GD] (1992–1998)
+* Jim Rice's [Homebrew STM][JR] (1995)
+* The Peddie School's [STM Project][PS] (1997–2002)
+* Jürgen Müller's [home-built STMs][JM] (1999–2006)
+* John D. Alexander's [STM Project][JDA] (2000–2003)
+* The Münster Interface Physics Group's [SXM Project][MIPG] (free

+The [Gnome X Scanning Miscroscopy (GXSM)][GXSM] project provides GPL
+software to perform standard SPM imaging.  The list of supported
+hardware is currently limited to the SignalRanger series by SoftdB,
+via GXSM-specific kernel modules like `sranger-mk23-dkms`.  There is
+an obsolete [[Comedi]] driver for GXSM that Percy Zahl wrote back in
+1999, but [it has been deprecated][issue1649579] since at least 2007.
