Does a florescent black light carry any health risks greater than that of a regular florescent bulb? Answered

Does it generate a higher level of UV radiation than a regular florescent lamp  or just "filter out" visible light with colored glass like the incandescent black lights? Should I worry about extended exposure to the skin or eyes? Thanks.

RFID tag ideas

I've got a handful of RI-TRP-DR2B 32-mm Glass Transponders...Don't really know what to do with them so I figured I'd ask around here.  I've attached a picture and the data sheet for this item.  Has anyone worked with these or similar devices before?  Also, any recommendations for a reader/writer (preferably something that'd work with a Raspberry Pi or Arduino)?  They operate on 134.2 kHz. Thank you.

BLUETOOTH INTERFACING WITH 8051(AT89C/S51/52) PLZ HELP

Hello guruz, recently i bought n bluetooth UART module (http://robokits.co.in/shop/index.php?main_page=product_info&products;_id=354) RKI 1545 I tried interfacing it with 8051 using the 10,11 pin UART pins, using SCON register(mode1) baud rate 9600. But there is no reception or transmission. However the bt module is working fine. Passed the loop feedback test(joined theRx to Tx pin of module standalone....link established echo received on Putty on WIN7 and blueterm android app )   CODE: #include void ini()     // Initialize Timer 1 for serial communication { TMOD=0x20;  //Timer1, mode 2, baud rate 9600 bps TH1=0XFD; SCON=0x51; TR1=1; } void recieve()  //Function to receive serial data { unsigned char value; while(RI==0); value=SBUF; P1=value; RI=0; } void transmit()  // Funtion to transmit serial data { P2=0xF4; SBUF=P2; while(TI==0); TI=0; SBUF=P1; while(TI==0); TI=0; } void main() { while(1) {   ini();   recieve();   transmit(); } }

how to make airgun valve from modded sprinkler valve with tube to blowgun?

Right, im stuck with this one, im in the uk and want to make a copper airgun with a quick fire method, i have chosen the valve on the gun in this instructable: https://www.instructables.com/id/A-15mm-Beginner--Intermediate-Pneumatic-Sniper-Ri/step1/What-thou-shalt-need/ but i have no idea how to makeit from parts in the uk, "air hose" is just not detailed enough, i need to know where to get it. by the way, im choosing to use copper instead of pvc, so i need to know how to attach the valve aswell... thankx 2 every1 its for a science project about laws of motion n i wann impress some ppl

Kitty TV

Every year, winter comes to RI (as it should). Then every year my family makes a cardboard house for the outdoor cats (they started off as one stray cat a couple of years ago, but of course multiplied). The cardboard houses would be thrown out at the end of winter since they would become soggy (even though we covered them in plastic bags) and an eye sore on the porch. Last winter, one of our friends got a little overambitious and made a house that was way too big (we could have fit both of our Golden Retrievers inside with room to spare), so the cats didn't use it. Last month I reorganized my room and decided to get rid of the cabinet I had placed my TV in. I was gonna toss or burn it, but decided to convert it in to a place for the cats to live. The light located on top doesn't light up, but is instead connected to a flashlight connected to the interior of the cabinet which does light up when the push light is "clicked".
