Re: digital clock

Sorry if this post is not appropriate! But I just couldn't resist! philba, what parts would a seven-segment digital clock like this take using a pic? Would the pic version of the same clock be as reliable?

Re: Lighted Hockey Puck

Hey philba, the transformer idea is simply awesome! I hate to tell you this, but I had already thought of the latching hall effect sensor. :) I didn't pursue it because I figured that I would just unscrew one of the AA batteries instead. But if I could design a sealed puck, it would be just the tick...

Re: Lighted Hockey Puck

Yup, real pond hockey! Last game I played, we had 5 degrees F. temperature and a light breeze! What I have done so far on my hockey puck, is to slice it in half with a hack saw and hollow out the middle with razor blades. ( Yes, it isn't real easy ) I've gone to my local hardware store and have re-e...

Re: Lighted Hockey Puck

Hi rocket scientist, Yes this is an ice hockey puck. It's not NHL though. It is for some country boys that just play on farm ponds when the ice is good. The problem is that we normally play at night since most of us have day jobs. The lighting isn't all that great, and having a lighted puck really m...

Re: Delco Truck Radio

Yeah, jimandy, your suggeston of connecting the ammeter across the pulled fuse jack is a good idea! I have never seen that done, but it has got to work. I'm positive that just a few minutes of working with it would find the circuit that is still drawing current after the ignition is off. I also thin...

Re: Delco Truck Radio

Hi Ed, I used to work on cars and trucks for a living, and I seriously doubt that the draining problem is your display. If you want to check, a very easy way to do that is to disconnect your battery cable and insert an ammeter between the battery and the battery cable. Start unplugging fuses untill ...

Inductance Tester

Does anybody out there have any nifty methods of finding out how many henrys an inductor has? I have a bunch of inductors that I've pulled off of junk appliances, and would like to sort them based on their inductance.

Re: Lighted Hockey Puck

Thanks for that one, philba! The AA batteries length is my single largest drawback at this point! BTW, I took your cue, and am experimenting with different color leds for different effects. I couldn't get your invertor circuit to work, although I didn't spend much time with it either, as I'm thinkin...

Re: Lighted Hockey Puck

Yup, we have two of those lighted Canadian pucks already. As far as the lighted part goes, there isn't anything better! But the physical properties of the puck really suck! They are made out of hard lightweigh plastic. The professional pucks are made out of something that closly resembles urethane. ...

Re: Lighted Hockey Puck

Thanks for the great input, philba! I'm going to breadboard your circuit as soon as I can! And yes, I did kinda lead everybody astray with th "up to 30 leds" earlier. I actually just want a hockey puck that would be really visible in low lighting conditions. You are supposed to understand what I mea...

Re: Lighted Hockey Puck

I have decided to try and squeeze two AA batteries into the puck. That will give me 3 volts to work with. How many red leds can I stick in it and expect it to last half an hour?

Re: Lighted Hockey Puck

Ok, Ok, Ok, I thought maybe someone would "burst my bubble" and tell me that I can't run 30 leds off of one battery forever! :( Now then, if that is not possible, about how many leds will I be able to power up for about half an hour? I will be using red leds. Brighter is better! <p>-----------------...

Lighted Hockey Puck

I'm trying to put together a lighted hockey puck. I would like to use one AA battery, giving me 1.5 V. to work with. I was wanting to know what would be the best led/resister combination to give me the most amount of light. I'm thinking about sticking up to 30 led's in the puck, and would like the b...
