here's how to make a stelthy flashlight that can be filled with LED's of your choice. Everyone will think this is posible with a normal compact flash

Step 1: Materials

-Compact flash
-mini-momentary pushbutton switch
-enameled wire
-soldering gun and solder
-masking tape
-drill with 5/32' drill bit
-dremel
-knife
-LED
-Welder contact adhesive
-clamps
-3v 2016 battery
-file

Step 2: Disassemble

take apart your broken compact flash with a knife and take out the board but keep the outside

Step 3: Disassemble Cont.

drill a hole in the front of the card and file down the edges

score with a knife along the sides of the leads being careful to leave the holes intact

if your the impatient type just dremel it out

Step 4: Solder

connect the leads of each side to one another but avoid soldering the one with a piece of metal to anything because there are two like that on both sides and they are connected to each other.

then solder the wires to the switch and tape them to the battery

when your done check the voltage of the device and mark it

Step 5: Assesemble

cover the sides with tape so not to short it out then stuff everything in and tape it down.

glue the board and sides together and hold them with clamps

for me the front side of the board was + and the bottom was -

Step 6: Done

now your done so you can plug in your LED or buzzer up to it and everyone will think it works with every compact flash
incredible. i wish i had one of these now...
i like this idea in the sense that it really is a miniaturized version of an led tester that employs a very similar concept with an ATA plug/ and or cable from an internal computer hard drive<br/>here is <a rel="nofollow" href="https://www.instructables.com/id/LED-Altoids-Tester/">link</a> to instructable i am talking about<br/>
thats smart
That is cool, a very convienient led tester too. Great use of the old card. I'll be cracking one here shortly.
Okay so I cracked one and the holes don't seem quite wide enough to accommodate the leads from the LED. Did you have to sand down your LED legs to get them to fit?
My 5mm LED wasn't a perfect fit at first, but after a few times of pushing it in it wore down enough to fit; I guess sanding it down would be good idea.
If you could conceal the button under the label, nobody would ever suspect you tinkered with it. Great prank!
This is actually pretty cool. When I saw the image I wondered "do CF cards have a tiny battery inside or something?". Well- this one does! If you used a smaller LED, this would be thin enough to fit in your wallet, like a DIY version of the "credit card lights" that are all over the place. I think you should turn "CompactFlash TM" into "CompactFlashLight" :)
Nicely done.
