it should depending on the battery's used. i would probably use LiPo battery instead of LiIon for drawing this much current. if you are planning on using this for a laser driver, it should be mentioned that it is a constant voltage regulator not constant current. From the datasheet it should...

sure is good to know that smart asses are still around on the internet. (badger) i figured it out after i made the post. it just didnt click with me how a rotating plate pressed against another was capacative. makes a little more sense now. i just dont imagine it to be precise. i just didnt...

is this GB going on or is there another for a decent set for a decent price

im building my own galvo's for a scanner(based on Chan's design) the build is going smooth so far. the question i have is... what is he using for position detection of the galvo. i see no IR detector/emitter or optical encoder. what would be a fairly simple position detection that i could...

where is the link. $70 for galvo and amp are you sure they are not stepper motors

if you didnt figure it out, you can use a LM338 in place of the LM317 and it's good up to 5A. if you are gonna run it at 5A you damn well better have a good heatsink on it. it is wired the same for constant current as the LM317 so the schematic listed earlier will work great you can also get a...

does anyone know how to find the Vf of a diode that is unknown. i have an IR diode from the LPC sled that im using as an IR illuminator for a B/W camera. im regulating current with a lm317. i know that i need to comp. for the voltage across the LM317 (~3.0V) but i dont want to feed it more...

ive got tons of 317's and a couple of lm338 to drive it ~5A but to drive it efficiently, im trying to find the Vf for the TEC so all the extra voltage going into the regulator wont be converted into alot of heat.

2A at what Voltage? 5? 12?

trying to start a new project and am having trouble finding info on the TEC used in the projector. searched and have seen people use them at 5V@12.5W (or 2.5A) but i dont know if this was accurate (title was "semi-ghetto peltier-cooled handheld lab device" ??? :whistle: anyone happen to...

add me. zip=36301 title=wonhunglow also ndrew2505 lives in dothan al also. not mississippi

I've got some Max 1811 single cell charger ICs that I've used for a while and have thought about integrating one into a single cell host. The only part I'm unsure of is how to use it in circuit. What happens when u start charging the battery. Is there a type of switch or diode needed. I know...

we get our 445nm diodes from these and our phatlight red led. that supplies the red and blue. what supplies the green to make the full color spectrum...:wtf:

well i did my part just as i said i would. sorry for taking up wasted space on the forum.. PEACE!!! :horse:

still waiting ..... no response. he must have figured out his mistake.

all this fussing and slamming me and i post a response and 2 weeks later stil no response. well i can only figure he found his mistake and didnt want to come back on here and admit that "maybe" i didnt ship out a bad laser. in any case i will keep checking back to see if anything else is said...

ndrew2505 called me and told me about this problem that i did not know about. i logged in and checked and had a pm.... ""WHL I have received the laser. I then went out of town. I just got a chance to get a battery for it yesterday. I was disapointed when I put the battery in and it did not...

as soon as you sent the paypal funds i gave you the trackin information via paypal i just sent you a PM with the TN also. thanks to all

sorry to all (except thegreatgoat) the listing has ended yesterday morning. the tracking information has been PM to you. thank you.

damn borgqueenx you should have held out. and thank you boosted_4cyl if it is still here on friday morning (i hope it will be sold by then.. :( )i will put you down for it. if someone will buy it today i will do it for $80.00 shipped. i really need this thing gone and the money in my account...
