DA BEST pa din yung nabili ko sa alexan na UV bulb. kahit 700, ay... sunburn to the max ka naman kung maexpose. as in lapnos. hehehe
feeling ko yung uv led mahina compare sa tig 700 na bulb. that can't burrrrrn!??!

experiments on a UV lamp...
*maglagay nang dahon, hamster, langam, daga, at kung ano ano sa exposure box.
(simulate mo kung wala nang ozone layer)
*i expose ang balat likod nang kamay for 30 seconds na nakadikit sa bulb.
*test mo kung 100 years life span nga ang color nang epson ink. (tried and true ok nga!)
*mabilis na pampatuyo nang paint, fiberglass resins, mightybond, at clear epoxy.
*erase rom chips.
*learn how non-ionizing radiation behaves. hehehe may ibang material TAGUSAN sa UV. kahit opaque na.
*disinfect ANYTHING. kahit tubig na nasa baso. naks.
*kung kulang ka sa Vitamin D. pwede din!

hmmmm di ko pa nakita yan ah!

meron lang ako yung etching tank nila

^hay nucleus... hindi ako ang alexan pero magtanong ka sa kanila at bibigyan ka nila. lahat nang branches meron sila.

ay... sabihin mo magrestock sila! galit ako. aARRGGGHhhhh.
difference lang is hindi napupundi ang LED... hehehehe. 20000h lifespan.

bihira din aman mapundi ang fluoro nauubos lang yung conductive gas sa loob

Pwede din naman yung mga 6W or 8W blacklights, pati na rin yung mga standard 10W na florescent blacklights. Madali pa hanapin sa mga handyman at ace hardware.

Mas maganda pa rin ang UV LED dahil mas robust at walang mababasag or mapupunding bulb.

honga yung sakin andun lang nakabalabag sa mga parts di nababasag

UV led:
pros:
robust
cons:
low UV emitting. much like black light.
expensive.
needed to be mounted on a pcb or soldered in place
cheap if you're making a 4 x 6 exposure box

UV black light
pros:
not as destructive as germicidal lamps.
cheap (uv money detector lamps)
cons:
not much UV.

UV Germicidal lamps
pros:
Intense UV radiation.
more practical uses
widely used in presensitized and printing.
Cons:
not as expensive in led but more expensive than UV blacklight.
destroys acetate, paper, etc.
harmful unless proper caution is taken.
cancer causing. unless proper caution again. is taken.

ubos braincells ko ah.

@insomartin
sis,ilan ba yung supply voltage ng UV bulb sa alexan?mas mura sya sa e-gizmo,around 1000 ata yung sa gizmo correct me if i'm wrong pero malaki!

OPTIMUS PRIME · « **Reply #31 on:** June 13, 2009, 01:54:28 AM »

mga sir seems I like the idea of UV leaad exposure...for portability, safety, exposure control, lifespan at positioning....may question lang po san nyo gamit ang angle? Im planning of honeybee configuration ( physics under optics) yung distance between leads naman in relation sa distance ng led to the exposure media (pcb) ang naisip ko. Yun lang po san nyo gamit angle?baka may pics kayo for me to understand

subzer0 · « **Reply #32 on:** June 13, 2009, 02:14:05 AM »

sa akin talaga sirang scanner lang tapos para may enclosure yung UV lamp tapos count down timer yun lang!parang ganito:

http://www.turbokeu.com/myprojects/countdown3.htm

@chris vp

ok kaya,yung honeybee configuration,pero no idea kung paano,optimization siguro dun sa LED?

OPTIMUS PRIME · « **Reply #33 on:** June 13, 2009, 02:27:55 AM »

Sir plan ko pa lang ang honey beee to maximize yung landing ng UV sa surface ng PCB. gaya ng flaslight my circular na projection yun, kung magtatabi ka ng 5 pa to complete the hexagon dapat edges ng light na project nila mag pang abot sa edges in that way maximize spread ng lead light( konti ang lead pag obra ang configuration na to, kaya medu experiment din ng konti. pede din cguro alternate na parang chessboard configuration.(Black n white ng board).
sa picture ok pala gawa nyo na exposure..proffessional ang dating :-)

subzer0 · « **Reply #34 on:** June 13, 2009, 02:52:28 AM »

yup tamang tama sir nagaantay lang ako sa tipidpc.com ng defective scanner,di kasi ako marunong gumawa ng kahon na plywood,pero mas preferred ko talaga yung All In One na printer yung may scanner kasi mas roomy yung space nya para sa UV Lamp/LED tapos butasan nalang yung gilid for the countdown counter.suggestion ko sir sa honeybee pattern try mo yung PC401 about the spacing,kasi pag ako gagawa nyan trial and error method yung gagawin ko

ok na yung inverter nang neon tubes na tig 200. di naman kailangan nang fancy balast. may nabibili nang gawa, palitan mo lang yung tube nang "money detector" na from blacklight to germicidal may balast kna

mas gamay ko ang germicidal kasi sobrang bilis mag expose sa 1 minute minsan ok na. about UV leds feeling ko mahina...

oo nga 1000, mahirap hanapan nang inverter type na balast pero tatanong ko ke sir henry kung mapadaan ako.

insomartin · « **Reply #36 on:** June 13, 2009, 02:59:36 AM »

honeybee? baka circular overlap lang...

naku sis masasaktan nyan si ate nucleus,ok thanks,ganda mo talaga!meron ako nakitang money detector sa electronics botique,kitain ko bukas sa mga DIY shops.

take note. that's the size of a 4x3 assuming 30 led na magagamit.
wala pa jan yung current limiting nang led.

hehehe. i mail nya na lang yung opa541 nya.

6 minute exposure and/or 2cm/minute.
so mabagal pa din.
