Same as MODUL1K, but for use with HeNe lasers.
Board level circuit is used with our diode lasers to produce a test tone, simplifying window bounce systems. Also modulates lasers for voice communication projects. Operates on a 9 to 12 volt battery with sensitive FET mike and level control.
|Available as a kit with all parts requiring assembly, or as paper plans with parts and assembly required (also available as downloadable plans for roughly half the price).|
