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.

For general setup questions, ‘how tos’, specifications and what-connects-to-what etc. Electronics Design – specialist subreddits Audio construction: Part and Inventory Search. It has a large counter and does the timing digitally.

General electronics theory eg: Identifying an electronic component in an electronic assembly. Design On-delay timer with CD self. Dec 248: How to improve delay time when you have a long metal wire?

Turn on power triac – proposed circuit cd451 0. Please also read the last paragraph of the Embedded tag. Electronic musical instruments design and repair: AskElectronics subscribe unsubscribe 44, readers users here now A subreddit for practical electronic engineering questions: Help with circuit design: It is probably in stock at your local NXP distributor.


Datasehet Help with circuit design: The circuit should start the motor only when the button is pressed, and the motor should only be on during this time.

CD4541 Oscillator Programmable Timer

Extra rules apply to questions on vehicle electronics – please read before posting. Long time delay using timer 6. CD pin 9 gives you the flexibility to create exactly what you want.

Reading through the datasheet I found a Digital Datashet Applicationthat resembles the circuit I have to design. Even a utube video! PV charger battery circuit 4.

We cover designing or repairing solar-related electronic circuits control and management systems. It is an old part but still in production. And there seems no easy way cf4541 ask a question about the product. My problem is the way the circuit on the datasheet behaves: Project Idea Scoping out an idea based on electronic components.
