I found this cool schematic online, but I can't tell what the polarity of the capacitors are! Can someone tell me the polarity of the capacitors on the right side of the transformer?
I got this working at 60 volts. And its only 10mA because I skipped the whole right side of the...
I mistakenly ordered a different one. I'm not sure if it will still work on a blu-ray though:
650nm 5mw 12X30mm brass case $4.50 USD
will this work for blu ray?
This is the one I got last time:
650nm 10mw 12mm X 30mm case $12.00 USD
I used this one for a senkat diode
I love the LM317 for my lasers, but its kinda difficult to cope with the 5 volts and up rule so it works.
Is there any current regulating driver you can make to use 3 volts? Cause the aixiz modules and lots of pen lasers only use 3 volts and they still regulate the output.
Anyone know how...
Hi, I got a few rechargeable lithium CR123a batteries. They are the protected kind.
I was wondering if I can just find some adapter in the 3.6 volt range and charge them that way?? I had this idea cause it says protects from over-charge, over-heat...and such.
Can I do it? if so, what ma or...
check out this sweet video!
EDIT: I just noticed that the can is a little tall. It looks fine on my widescreen. But my projector is at regular mode and it looks a little funny.
I just recently ripped apart an old RC car and was planning to use the steering coil to make a scanner.
The first one was a small car and was different that I expected. I expected a coil and magnet. Instead, it was just a 3 volt motor with gears. I was disappointed. :(
The next car was a...
I just got a new butane gas powered soldering iron last week. I got it from radio shack and it was about $20. I like it because it has no wires to worry about. The main problem I have when soldering with my other irons is the wires. I have a corded soldering iron and de-soldering iron. The...
Hi guys, I thought I would make this little story explaining why I think ebay is ending the selling of high powered lasers.
Its all explained in my little story.
EBAY CUSTOMER age: 20
BOB age: 21
THE FOLLOWING IS LASER STUPIDITY AT ITS BEST
EB customer: I've always wanted a green...
After pulling off these batteries from the charger, they read 1.7 volts each. I'm not sure if thats a big problem or not. They seem to hold that charge at the same rate as normal use.
Its only this one kind of AAA that does this in this charger. The others are fine.
I know that the cold makes it change output, but why does it flash output from low to high rapidly?
It is noticable when looking at the opening of the aperture from the side.
Basically what I'm asking is what is causing the rapid unstable output changes? is it the diode?
One of my friends is a littlle weird. I told him to be careful with the red laser but he intentionally looked straight into it. :o He doesn't listen very well.
He said he can see fine, but I'm sure there is unseen damage. It wasn't fully collimated, but still.
Hi guys. I thought of this when playing with my DX 5mw outside. Its about 30 degrees F outside and my laser just won't shine bright :'(
Found some foam and drilled it out and stuck my laser pen inside it. IT WORKS!
Watch the video for a look:
UPDATE: tomorrow I will make a new model that...
I just reveived my DX 5mw green today and it is so cool! I already have a burner red so I'm not worried about a green burning.
But I wanted to see what would happen when I put my Aixiz lens from me red in front of my 5mw green. When focused at a tiny spot on the bag, IT ACTUALLY WENT THROUGH...
Hi guys. I need help understanding the LM317. I need to know which is Vin~Vout~Adj.
I've been trying to make Daedal's circuit the way it is shown. I've made it THREE TIMES!!, and it still won't reduce any voltage whatsoever!! I'm completely confused.
When I turn the 100ohm pot to max...
