LCS-1M: A Low-Cost Hobby Oscilloscope
6. November 2008 - 18:06 — admin
An oscilloscope is an invaluable tool for anyone working in electronics. LCS-1M is a simple yet full-featured homemade digital sampling oscilloscope.
Main goals for the LCS-1M was:
* Create something that is really usable in practice - i.e. it must have sufficient sample rate to at least cover the audio range (DC up to well over 20 kHz), and a wide input range (from Millivolts up to several Volts).
* Keep down cost as much as possible and design it in a way that all the components are easy to procure and assemble, so any moderately skilled hobbyist can build his/her own.
* Make it easy to use so even a user without much experience with oscilloscope gets a quick start, and make it compact so it doesn't use much desk space.
* Last but not least: make it an open design so anyone can improve upon it.
