    Testing the CDI? units

    Yes Frank, i was thinking the same only but wanted some expert support to the fact that i can use the oscilloscope to check the cdi circuits on the basis of calibrated one against good working ones , 50kv probes aren't a problem will buy it and what you say how much Mhz potential should be there...

    Testing the CDI? units

    Im developing the capacitive discharge ignition systems but im not aware of the method of testing it apart from plugging it into the respective vehicle for which is made, now the problem with this method is that im developing cdi's for a very large segment of vehicles so i can't probably buy all...

    Making IR Receiver using PIC16F84, ability to control 4 Different relays

    Thank You! Tahmid , What you think, Is the RC - 5 Technology is used in Channel 100 TV's also like their Predecessor's Channel 90 which are compatible with Rc - 5 Protocol? and is their another protocol that i can have in my circuit apart from RC - 5 ,Sony and other popular Protocols?

    Need Simple Modification to Infra Red Circuit and HEX FIle

    But Even if there is a problem of interference with old 90 channel tv remote, is there a Remedy?, The much i know i'll be using a Shield or plastic transparent cover of relative thickness so that it becomes mandatory to point in the direction at which device reciever is located, what you think...

    Need Simple Modification to Infra Red Circuit and HEX FIle

    What can be Done About Interference with other IR Devices? ,Like Signals from other IR Remotes, I mean RC-5 will definitely save my device from interference with other company remotes than PHILIPS but what about if i have PHilips TV or other appliances ,will Interference Occur?-------My remote...
