This is a great demonstration of a very old carbide lamp. https://www.facebook.com/reel/910642031084858?mibextid=9drbnH&s=yWDuG2&fs=e

2015-11-18 Flashlights Continued
After the 2015-10-26 blog, I searched for some other websites selling small flashlights and ended up at dxsoul.com, which is a part of Deal Extreme, DX.com. I also found some reviews of other, cheaper flashlights, two of which were the Brinyte and the Tank007. On dx.com I found and ordered the the package called ‘Mini

2015-10-26 Flashlights Fenix E01, LD01, LD02, ITP EOS A3
This blog continues at 2015-11-18… I just finished looking online at Fenix LD01 and E01 flashlights (torches). I was shocked when I found the prices of the LD01 have skyrocketed to $42. I looked at the LD02 and found it also uses a single AA cell, but it has a push on, push off switch

2014-11-06 Other Useful Things From DX.com
I saw a few items at DX.com that look like they could be very useful. A USB power meter, with even more information in the display, compared to the somewhat lame Practical Power meter. You won’t be caught with a dying cell phone battery with this. It’s a useful addition to your flashlight collection. This

2014-11-05 Flashlight & Warm White Strawhat LEDs
I’ve thought about putting a series string of LED lamps into a Moebius Loop to make a free energy generator. No telling if the thing will work. 😉 The LEDs I bought a box of 100 Sencart LEDS from dealextreme.com more than a month ago and they finally arrived this week. The cost was under

2014-09-27 Solarforce Z2 Flashlight
I ordered and received a Solarforce Z2 flashlight a few weeks ago, and I’ve been using it for a few weeks. It uses a AA cell, and has a push on, push off button switch on the rear end. It also has tabs that stick out past the switch so you can set it on

2014-08-01 Electricity Grid Stability
This article is an assessment by the coal mining industry, and as such, it is most likely heavily biased. The reason I blog it is that it gives an idea of what the EPA is implementing and what the consequences might be. What does this have to do with LEDs, you might ask. Well, we

2014-07-16 ITP A3 EOS 96 Lm Flashlight
I’ll get to the ITP flashlights/torches asap, but first a bit about the ThruNite flashlights. The ThruNite Ti2 80 Lumen flashlights were only $11 apiece, so I ordered a few. They use an on/off switching arrangement that I haven’t seen before. Once the head is twisted to light at low brightness, tightening it another quarter

2013-12-19 Mechanically Rechargeable Lights
See Note at bottom. Years ago I bought a shake flashlight and it was nearly worthless. I shook it for quite awhile, and as soon as I stopped, the LED went dim. So how am I supposed to shake the light and try to aim it as something that needs light? And if it wasn’t

2013-07-01 Peltier Flashlight
QS sent me a link to a design that supposedly uses four Peltier tiles to generate enough light to be used as a flashlight. Apparently there are no further details. There are some points to ponder in what the link said: It used the word ‘objective’, which means it’s something that they hope to achieve,
