    100W LED - Flashlight

    nice but so big have tryed it little smaler http://marderchen.de/NEU/MEOW_highpower_NE555_step...http://marderchen.de/NEU/MEOW_highpower_NE555_step-up_running_needstrondercells.jpg but cellpower break down (discharde current far to high) have to order li-po flat cells.. also smal laptopfan and lens (relay get better results is creating stepupcircuit running with highte frequency on your own) and maybe calculate the 200 and 47ohm resistors or use other NPN/PNP transistors caused estimated this part (BD1340 is strong enough to switch some IRF1404 parralel)have fun [MEOW] =^.^=

    DIY Bluetooth Speaker Under 5$

    the difference is simple.. the orange capacitors alow higher frequency spectrum.. (if just wand to recieve bluetooth audio without data mp3 storage therer is also amplifier and bluetooth on one board: http://www.ebay.de/itm/3W-3W-Wireless-Bluetooth-4-0-Audio-Receiver-Steady-Digital-Amplifier-Board-/272322746439?hash=item3f67b35847:g:JAAAAOSwRgJXmes6 ) =^.^=

    DIY Bluetooth Speaker Under 5$

    cute circuit (build something like this years ago.. .. changed the speakers in phones , and using a old handy accu (with li-ion usb charging board.. )watch picture but now i know http://www.ebay.de/itm/5PCS-2-Channels-3W-Digital-power-PAM8403-Class-D-Audio-Amplifier-Board-USB-DC-5V-/182333036435?hash=item2a73e55793:g:vy8AAOSwo6lWQDzV is the same amplifier ic, cost little more, but the circuit improfes the soundquality..) i don't see a bluetooth module.. so its just a active speaker.. maybe adding this http://www.ebay.de/itm/Wireless-Bluetooth-4-1-AUX-3-5-Car-Phone-Audio-Amplifier-Verstarker-Modul-USB-TF-/142096106254?hash=item211596830e:g:i4kAAOSwdzVXvXN3 play also mp3 from USB stick/ sd card.. =^.^=

    Powerful burning Laser

    Nice.. (pulsing the laser is much bettet for getting more power.. so maybe try a simple NE555 circuit) but pleas do yourself a favor and do not buy ULTRAFIRE Li-ion cells.. (shown in video the typical red /black stripe look..) (have test they.. the real capacity is only ~1000mAh (mostly they are labled with 4800mAh etc...) also the don't supply a high current.. (and its dangerouse to charge them fast ) but the hole tink looks expensive.. ( http://www.ebay.de/itm/High-Power-250mW-Focusable-Laser-Module-Battery-Case-/161532045523?hash=item259c0f68d3:g:NLMAAOSwuMFUmToQ have buyed one.. some time ago.. (not sou powerfull like yours.. but it works https://www.youtube.com/watch?v=8yIRPoYDDm0 .. maybe finde some time to change the "resistor circuit to STM32 or NE555 puls circuit.. ) =^.^=

    Battery powered fog machine

    Nice simple work.. (but why using AA batteries if have powerfull Li-ion (Li-Mn) cells aviable ? Have thinking about build the vape source self? myabe think about using a serversupply fan.. (they have up to 8800rpm and are verry smal but strong enough.. they required 12V but its not a problem with dc/dc step up module..) aslso maybe add a led light inside.. for light the smoke.. (or a laser)(FLASH video file from my STM32 OLEDselfmade electrical (!rainbow) cigarette.. in addon.. or in my google+ collection documentation and other stuff.. https://plus.google.com/u/0/collection/AXBhqB myabe you get some cute ideas..) its not a good idea to use a electrical ciragett for this.. the "normal you can buy are made for short running and big breaks (they are running verry hot if juse perm...
