    Designing a Time Delayed Relay

    Nice!! That is exciting :D, does this mean you are prototyping or packing? On second review today, I think I hit a stumbling block with the application of the logic in the code. The idea to check for max and min and wait until they are stable by checking for little difference between the two...

    Designing a Time Delayed Relay

    Post 363 should be all I need to complete the program, but I am stuck on this line in particular right now. You say that if both conditions are true, then you are done looking for the peak to peak. If both conditions are true, that means the ADC output is either greater than previous max or less...

    Looking for a used scope?

    LOL :D:D, you spotted that at a Restore?! That is pretty amazing, the things we find down here are not as noteworthy...

    Designing a Time Delayed Relay

    @hevans1944 and @CDRIVE - you guys are too much :oops:;) I am still making my way through the electronics world and very aware that I am a rank novice still. I thank you both for the encouragement! I am very keen on learning enough to not only complete but continue on my electronics 'bucket'...

    Designing a Time Delayed Relay

    After a little bit of thinking and toying with some code, I have some thoughts, clarifications and perceived problems for discussion. I hope the section below will allow all to follow along without having to review the last 300+ posts or outside documents! To clarify where I am: I need to...

    Designing a Time Delayed Relay

    Indeed! I do like the simple to interface aspect, but I also enjoy the pain ;) You have certainly made me think about the system once more - I have other projects that I would like to have on a much shorter development cycle!! Maybe the next go around will be with a picaxe.

    Designing a Time Delayed Relay

    I think the code will be simple enough once I put some thought into it - maybe a case statement or a nested if then else will be sufficient. I love the idea behind the picaxe - making it more accessible and I believe Constantine is working with them now (HellasTechn), but I don't care for a...

    Designing a Time Delayed Relay

    LoL - Chris, I am still doing it caveman style - when I'm out there at all lately!! I think aside from debugging any upcoming issues, we are nearly done here, but I'm still at it ;)

    Pin 7 of 555 timer doesn't discharge

    Could we not simply gang a series of 555 timers with the input trigger of the next stage be tied to the output of the previous? Thus we increase the max constant with each added chip - cumbersome in comparison to a pic, but way simpler for an experienced analog fella to follow.

    Designing a Time Delayed Relay

    Its been awhile and I would like to thank not only Kris for helping me and inspiring me to learn more about electronics, but also to thank Hevans for continuing to help me pursue this and other projects. Thank you both!! :D As Hop mentioned, it might be a good idea to create a state diagram to...

    Homemade PCBs with a Brother printer - 4mil Traces

    I second that - I have had mixed results with other media, including the blue stuff - the dextran coated paper seems to be the best to date for me. I think some of the success is in the fact that the paper and dextran separate when wet vs. the blue paper is more of a transfer off and sometimes...

    Getting value of ADRESH out of a pic μcu?

    Yep! Lots of rain, but inside all is well :-) Cool!! Glad it finally got there. Yes, test fit your parts, you never know since I sized this for the parts I had on hand. I am glad I have a working version, its a lot better than breadboarding in the sense that you know that you have a working...

    Getting value of ADRESH out of a pic μcu?

    Thanks Hop, I am having some trouble following this logically. Please assist: Changing ADCON register to 1 gives right justified result in ADRESL - ok :) ADRESL contents from 0 to 7 are LSB - ok :) Adding the MSB back to our variable with ADRESL contents - ok :) Why are we multiplying ADRESH...

    Getting value of ADRESH out of a pic μcu?

    No worries mate, it was a good challenge to learn to spot things in code for me too!! The code works and now my dev. board responds appropriately, in this case it compares the range of the potentiometer and when the input is between: 0.00-0.97v (000-050 in 0b) GP2 lights up 1.46-2.87v (075-150...

    Getting value of ADRESH out of a pic μcu?

    Here is what I have so far: /* * File: devboard.c * * * Created on June 2, 2015, 9:33 PM */ // #pragma config statements should precede project file includes. // Use project enums instead of #define for ON and OFF. // CONFIG #pragma config FOSC = INTRCIO // Oscillator Selection bits...

    LM318N comparator circuit

    Hi Constantine, I am not sure if this will help your friend, but a quick search finds this:

    Getting value of ADRESH out of a pic μcu?

    Found this to be cute: Meanwhile, it's together in the same register (ADCON0) so when you initialize the values to turn on the A/D converter and set the channel, you have to set this bit in a separate instruction code. Wonder why that is... Reasons why we RTM ;)

    Getting value of ADRESH out of a pic μcu?

    Brilliant Adam - its of much use thank you!!! It is clearly commented and not obfuscated with many function calls - very low level and simple, easy to follow along. I will see if I can put it to use later on today, thanks again for finding that :D

    8-Pin Development Board

    Or perhaps not until next week if that board makes it in tomorrow ;)
