    Vacuum Tube LED Candle

    Not to mention the filament is indeed a heater which generates the excess electrons needed for tube operation. Heater implies current so the filament would not just create heat but use considerable power as well.

    Seems I couldn’t respond via the link that your response provided. I will be very interested in hearing how your joule thief tests go. Your results will depend on the quality of the circuit you build but it will be better than not having one at all since two AA batteries (3vdc Max) discharged to <1v is close to the best you’ll see going cold turkey. The thief should be able to get you down to <.3 depending on the semiconductors you use but it’ll be good whatever you do. Please do let me know. Your idea of a simple modular plug-in power supply is great. That will solve all the power requirement problems and be very simple to implement. I posted another comment (or attempted to) but it doesn’t look like it made it. Someone suggested you excite the tube filame...

Your idea of a simple modular plug-in power supply is great. That will solve all the power requirement problems and be very simple to implement. I posted another comment (or attempted to) but it doesn’t look like it made it. Someone suggested you excite the tube filament for lighting but I’m wondering how well that will work. The filament is a heater and is designed to be energized in order to create the excess electrons required for the tube to operate as designed. As a heater that implies current, maybe a bunch, even close to an amp depending on the tube. Not necessarily a great approach unless you just want to enjoy the tube’s natural glow and you are not concerned about energy consumption nor heat. Either way it’s totally cool. Please let me know what else you might do with this project. I think it is so cool!

    Another thing is to build a little joule thief curcuit. It will increase the battery life. There’s a bunch of simple ones around. Essentially it’s a switching power supply that allows you to us the voltage available below the cutoff of the led which is about .6V. You can take it wayyyy down.

    Unusual Uses for Ice Cubes

    For 30 yrs I've successfully avoided have anymore of those painful cold sores using L-lycine tablets which you can buy anywhere. Walmart. Anywhere. It's a simple nutrition suppliement and is cheap. I first heard about it from a pediatrician when our kids were young to protect them from catching it from us. So when you feel that first tingle that one is coming on, gobble down a few tablets. So the same thing 2-3 times a day for several days amd you'll never have a sore again. The key is to start the nutrient AS SOON as you feel it. If it becomes a sore and breaks the skin it's too late. Gotta get it AS SOON as you first feel the tingle burn thing before it becomes a sore. This does it every time. My siblings and I got them as kids but not for me anymore. Thank you Mr. L-lycine.

    Great post. Have tried this technique several times over the last couple of decades with limited success. I'll try it your way next time and see how it goes. I just reverted to one of the online companies where you can design it on their site and they'll send the board to you. A good way to go but it costs a bit. Really liked your post but would like to add a couple things all of us techie types should be careful of. Most importantly is getting chemicals on our skin. Even the finger nail polish remover. Acetone is quickly absorbed and is damaging to the liver. I know everyone ignores that but always wear some type of synthetic gloves when doing that. You'll be grateful you did in 30 yrs! Avoid fumes too as best you can!!! Same goes for the etch. Carful on the skin.Disposal. That's a tr...

Avoid fumes too as best you can!!! Same goes for the etch. Carful on the skin.Disposal. That's a tricky deal and an annoyance. If you can't do it the best way try to heavily dilute it before dumping. We gotta care of our health and the environment!Thx for reading this book. Haha

    Supercapacitor Joule Thief

    Pretty cool!I need a simple voltage regulator circuit. Maybe you can help. I have a solar charger for my car cig lighter but it can over voltage. I thought about a 7812 biaed up to 13.2 (car battery charge V) but that's pretty sloppy. I need it to regulate then shut off if < min voltage. Got a simply circuit for me? Thx!!
