Hi! Thanks for your interest in #Pomelo: Gamma Spectroscopy Module!

  Are you sure? yes | no

Thank you for liking and following my #Telescope Mount Controller using PERSEUS-9 and #Homemade Floating Point Interpreter for 6502, and thank you for following me! This time, I believe it is able to show that a practical system can be created with home-made hardware and software even with 1970s style technology.

  Are you sure? yes | no

Thank you for following my #CMOS Homemade Operational Amplifier and #Homemade Successive Approximation Register ADC ! CMOS Operational amplifiers and ADCs are widely used, but I would like to properly understand their internal principles.

  Are you sure? yes | no
