Tell us about yourself!
Hi, being as this was created 4 years ago, I would assume there are changes to libraries, it's a great opportunity for you to revisit and remix this 'ible :) Thanks for taking the time to comment, I do appreciate it :)
It's need over 4 years since I did this ible, could be that the RTC module code has changed. If I ever get the change to go back over and re-make this, I'll ensure it's using the lastest libraries..
Most probably, but I'll let you have the fun of figuring it out and it's a great opportunity for an awesome Instructable :)
Goof luck with the build, what I was meaning is the only parts from the original lamp used.. In fact, it's slightly wrong as obviously the shade is required as well :)The Base and rods are still in the center where they should be, it does use the weighted stand to hold upright.. Hope that helps.
Schematic doesn't show caps.What is the Max Current the 7805 can be used at continuously with and without a heatsink.Whats size heat sink ?v.poor, like most of your other 'ibles.. Take more time, be acurate :)
Theft (in 99.9% of countries) now gets featured !!!!
brilliant idea, please send me a link to the completed item :)
Excellent, hope it goes well
Need to be careful with the current draw on the relay coil, and if using a number of them this can cause issues..Also, nice to see a flyback diode in use, good 'ible, but could use a bit more detail on the circuit design, is the transistor npn or pnp.. Some will know, some won't, always worth adding in the extra few lines of explanation.. :)Maybe even a couple of words on a snubber with inductive loads on the switched side of the relay ?
This is good apart from the last of discussion around the heat dissipation and load capabilities of the LM7805 in it's various form factors...Rather than go into the technical details there is a very informative post here: http://electronics.stackexchange.com/a/21135
