datzsheet Then it will be more meaningful to discuss. Electronics Design – specialist subreddits Audio construction: You want the ‘Repair’ tag. What I need is that the motor starts immediately after the circuit is on, and then turns off after the timer has ended. Welcome to Reddit, the front page of the internet.

Programmable Timer

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 cc4541 a real obvious error not even getting his criticism right.


Equating complex number interms of the other 6.

It seems that this may be what I have to do. Ask the mods before posting. It is an old part but still in production. Anyone have any ideas? Do you have any recommended readings in the matter? Please tell us roughly where you live – especially if you are looking for a local supplier! Submit a new text post. Become a Redditor and subscribe to one of thousands of communities.

OK, go right ahead; you ARE ‘troubleshooting’! I was so frustrated at Rontierras post that I would have retracted the schematic if i could have figured out how to do it. For general setup questions, ‘how tos’, specifications and what-connects-to-what etc.

Losses in inductor of a boost converter 9. Q output of the CD shows connected to Vcc shorting the output. PIR sensor module etc May be it can provide the trigger pulse after power up. Any one with a brain could easily see what that part of the circuit is doing even with the resistor missing. Want to add to the discussion?

Construction, mods and powering: What is this Identifying an electronic component in an electronic assembly. The base is always floating not great either. Synthesized tuning, Part 2: I wish I could pull the schematic I posted off.

First, check out our list of national and global suppliers. General electronics theory eg: How does setup time impose maximum delay and hold time the minimum delay? I dont think it matters if you use S6 or S7 if you dont need the delay function.


I wasn’t designing the board I was reverse engineering it to get an idea of it’s capabilities as it obviously had more than the manufacturers “datasheet” suggests.

Lighting, audio, wiring, fixing etc. After some time when adaptation with environment is complete, its output goes low and becomes ready for proper operation. Help with circuit design: A subreddit for practical electronic engineering questions: This chip is suitable for high voltage 20v supply. Is it a modular system such as: Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Modification Modifying an electronic circuit or product at component level.

The circuit I need to design is supposed to be used on a motor, so the starting value shouldn’t be high, otherwise the cd45441 will just start when I power the circuit.
