Scanmate Audio Activated Recorded -  Add this easy project to your regular scanner or DX'ing apparatus and never miss action again....[Tony van Roon's circuit]

Scenix & PIC Programmer -  ....
Scheme implements multiple output ports -  02/16/98 EDN-Design Ideas....In µP/µC systems, you sometimes need to use many output ports and update all the ports simultaneously. For instance, in systems that use multiplexing techniques, the output ports require refreshing for every scanning period. One example is a system of multiple dot-matrix LEDs....File has many circuits, scroll to find this one....[Design Idea by W Kurdthongmee, Nakorn Si Thammarat, Thailand]
[_OLD-ads-dont_upload/OLD I-ADS from web/ad-djandassoc.htm]
Scheme Speeds Access to µP's Real Time Clock -  06/04/98 EDN-Design Ideas.... Amplitude limiters are necessary in many systems, such as radar and FM receivers, for which the system cannot allow the amplitude of the signal to exceed the given positive, negative, or both limits. In the circuit in Figure 1, amplifier IC4B's maximum outputThis file has many circuits, please scroll to find this one....[Design Idea by Jerzy Chrzaszcz, Warsaw University of Technology, Warsaw, Poland ]
SD Card Reader -  SD memory cards, especially the ones under 1GB are cheap, relatively easy to interface and provide vast amounts of memory for imbedded control…. [Luhan Monat - Mesa Arizona]
