huh so i guess the listing was a mistake? by what i can tell from reading these last few post i ordered 4 i guess ill check my messages on ebay when i get home.

today i attempted to make the circuit a little smaller and and more cost effective but i have a summer cold so it was a failed attempt lol

thanks and before i really get into building a prototype i have a couple of projects including this one but i needed to see if there was a market in it before i started spending money. ill be building the spiro in the next couple of weeks.

yeah a time tunnel is no problem and a three mirror spyro will get you more than a tunnel effect and if you have a module my circuit can power it to do more effects like slice n dice the time tunnel like i have here in this thread...

well it would depend on how i made them either on designed circuit board which would be a step up or prototype style which is still reliable just being cheaper and completely hand made = more work but the pcb would be more expensive in low quantity. how much would you pay for one being like lets...

i was wondering if anyone would be interested in some pre-built laser spirographs or if you would like to assemble them yourself you could do that also i could send it as a kit. i am very interested in your opinions and i see that everyone has a list of lasers in there signatures and wouldnt it...

i highly advise safety glasses and i think anyone on this site would say the same. it wouldnt be fun to be blind than all your going to do then is hear the birds and not know where they are to scare them away :cool: <----blind guy lol

i read that there was some trial and error with the voltage regs if anyones got any questions i can answer them -Dakota

it looks like some sort of antenna

Re: 405nm laser pointers $2.95 each? wtf? just ordered 4 i hope to make like 40 bucks on these

if you were to calculate the speed which i think is what you do want to calculate and find a relationship with the mW and speed you should look into hall sensors and a tachometer my friend just built one to show the speed of a large dc motor he put a magnet on the fly wheel and it takes the...

Re: 405nm laser pointers $2.95 each? wtf? im gunna order two of these with the chance of resale maybe 3 or 4 actually

Re: my new 1W 589nm labby!!! (joke) ive been posting my new diy galvos n such and ive got more stuff to come i just got my hard drives machined down today and i got some mirror mounts for motors made 1-5 degree angles and for my 4 mirror spirograph. and ive got good hopes about building a RGY...

dam well thats the first time ive been 8-bit rick rolled me and my buddy had a good laugh and then went back to having lives... :crackup:

i believe this is the thread you were referring to ----> http://laserpointerforums.com/f52/cni-pgl-rg-portable-yellow-red-green-43601.html says on there it houses a 30mw green and a 150mW which is what im aiming for so it looks like thats what i need and i could also experiment with my 50mW...

ok thanks guys i will be checking more threads out today but not for the whole night because my freind is helping me mount my hdd galvos and hopefully machining some mirror mounts for dc motors :drool:

im going to get a beam combiner out of a phr sled. and ONCE i combine beams i will pulse the lasers fast enough to "appear" yellow but since thats just a line it will look yellow but since the motors on a spirograph are moving it across a distance the line will dashed red and green and red but...

so you think when they're combined it wont be yellow? have you ever combined your beams before? oh yeah and what i plan to do is pulse drive both lasers opposite of each other so fast that the beam will seem yellow and once you put it through a spirograph it will be split into red and green...

i was looking into building a red, green, and yellow laser i know i need a turning mirror atleast im pretty sure. i bought a 50mW from laserlands a while back and now i need a red and ive been looking for a review and cant seem to find one for this laser----->Industrial 150mW Red Laser Module...

great work :gj:look up 555 timer pro and that would help you with duty cycles. keeping them the same i thought about trying it but i dont know how to do it i never researched it enough but i should for my next build i used a 555 here in my three mirror spiro for my laser ----->...
