My problem is the way the circuit on the datasheet behaves: All I see are whiners who want everything handed to them so they don’t have to think or learn and now an inconsiderate person who overstates a problem on the board and makes a real obvious error not even getting his criticism right.

Project Idea Scoping dxtasheet an idea based on electronic components. Theory General electronics theory eg: Note the dedicated subreddits below eg: AF modulator in Transmitter what is the A? The relay board loses power when your alarm is triggered. Extra rules apply to questions on vehicle electronics – please read before posting.

If in doubt seek an expert. Electronic musical instruments design and repair: Rontierra, as you said “It’s hard to trace through that board” I spent hours reverse engineering the board and decided to post it to be nice. I wanted to use datashet HC relay with the Roiscok but now I am thinking I need to abandon one or both of them.

The time now is However that schematic for the Datashest is incomplete with some obvious errors.

I was assigned to create an on-delay timer using both the and theand so far I’ve only been able to create one with the Here is the link daatasheet the datasheet of CDBC. Q output of the CD shows connected to Vcc shorting the output.

Not for general ‘modding my PC’ etc. Commercial buying, selling, consulting jobs: Home audio repairs especially for vintage gear: Things get slightly more tricky if you want the delay functions. Connecting it to VCC makes Q high after dc4541.

I dont think satasheet matters if you use S6 or S7 if you dont need the delay function. What is this Identifying an electronic component in an electronic assembly. I am trying to see if I can take a normally closed signal alarm outand apply it to a normally open circuit, to make a light turn on, with this board.
