  • How to repair a solar powered LED garden light

    china. ebay them. dirt cheap. if you dont like waiting I've had luck removing the panels from the dollar store garden lights while heating the underside with a heat gun.....not sure if this damages the panel but I heat it just enough to be able to pop away from the adhesive. for $2 (local dollar store price) you get a solar panel and the neat little circuit inside. Even ebaying them from china would still cost you more than buying it locally and disassembling it.

  • Simple and intuitive web interface for your Raspberry Pi

    Hey guys!A little update....Whew! A month and a half waiting for 555 timers from china! Worth the 1.00 for 5 though IMO.....they cost around $7 locally.The wiring is done, but I'm having a problem where the LED blinks when the relay is closed. Not sure if I have to change the config of the relay pins, then the code, or if theres something I can do to the 555 circuit. It's also very dim, so I'll have to power them from an external power supply. I used a 6v wallwart and they were bright when all 8 were on. The resistors used for the LED's are 220Ohm which were calculated for using 5v as the power source.I'm just waiting for the spare time to sit down and finger it out.I JUST HAD A GREAT IDEA THAT MADE ME JUMP ONLINE RIGHT NOWI'd like to monitor how often each relay is left on.Maybe even w...see more »Hey guys!A little update....Whew!

I'm not up to the task of trying to code it from scratch, but I'm sure I could find something on the net to piece this together. I'm sure I'll have to buy the RTC for the PI, right?Anyways I mostly came on to show that I havent forgotten about u guys and that it's still a work in progress. I blame China for tyhe long delay :D
