This display was made with a row of LEDs connected to an ATMEGA32 based dev board (microHOPE). The rig was taped onto a table fan, and was used as a demo to enthral schoolkids at IISER Mohali for Science Day.
A room temperature prototype of an STM. Uses the R9 from RHK, an Attocube Walker, and a piezo scantube. Steps in HOPG, and a 10um calibration grating were imaged

ATMEGA32 based MCA for radiation detection and spectrum analysis
Had to throw out an old CRT monitor. Decided to open up the case, and play around with the deflection coils a bit
