I attended my nephew's wedding this past weekend. They chose to use the flickering LED tea lights as part of the centerpieces at the tables and being the geek of the family, I managed to bring home a bag of around thirty of them. :8) I think if one were to gang three of these things together, the ef...

A few years ago, FSM printed an article where a guy hacked one of those little am radios (the kind you get for free a a promotional item) to have the earphone output drive a red LED. He used it to light a campfire in a diorama. I don't remember all the details but, at the time, the idea seemed like ...

I built a booth from a plastic storage bin, a bathroom fan, a small fluorescent light, a dryer vent/hose and some electrical bits. It has served me well. It's also pretty portable. I just put the vent and hose assembly inside and close the lid. the fan sticks out the back but it's not a problem to c...

I voted for the wireless transfer (induction?)- In particular I would love a nit which could be built into a stand and a smaller/cheap reciever that could be installed in several models so I could light something by just putting it on the stand, swapping as I felt like it. I have to rotate my model...

A lot of folks who produce resin kits actually take the time to knock off some or all of the flash, when possible, before kits are packed up for sale. I consider that extra attention to detail a customer service thing. They certainly don't have to do that. I assume that some flash is unavoidable. Ho...

You didn't say if you have a current limiting resister in line with that LED that's running off 9v by itself. With that much voltage, you're going to need one, otherwise the LED WILL get hot (but only for a second before it quickly burns out :lol: ). You also didn't say what color the LED is. White ...

I've been using one of these for the past couple years now. Probably the same thing. Even though you're supposed to be ABLE to cut wire with them, if you plan to use it to cut sprue, I recommend using it ONLY to cut sprue. Cutting wire eventually dulls the blades but mine is still shiney and sharp s...

The problem could actually be much simpler. If you spend too much time with the soldering iron actually in contact with the LEDs' leads, you run the risk of causing heat damage which can shorten the little guys' lives. An LED is actually a tiny junction between two chemicals which are usually very s...

I mostly agree. You will need 2 of the 4049s, though. Remember that the 4049 outputs are only rated for 5ma max. Yeah, I forgot to mention that. You need one inverter (not gate) per output from the counter. Since the 4049 only contains six inverters (that's why it's called a hex inverter) and your ...

I've experienced the effects you're describing when I've used old cans (I mean a couple of years).

Here's what I do: Get the mating surfaces of the two parts to be joined as smooth and gap free as you can. Then place a generous drop of paint in the spots where you want the pins to go on one of the two mating surfaces. Next, carefully dry-fit the two parts together, making sure the drop of paint o...

My guess it those boards weren't meant to drive LEDs. I doubt that chip is anything more than a custom brute force sequencer and the transisters are there to provide isolation for the four series strings. Since the chip is probably built to run off 110v rectified, it probably wont function on anythi...
