Hello people of LPF,

I am trying to make a recreation of the classic "301" style laser, that fits with modern hobby laser tech and will be easy to use and assemble by hobbyists. I made some prototypes of how it might look. They are relativly similar there only diffrences are how the copper module fits into the host, one design allows the 12mm copper module to slide smootly into the host/heatsink with around 1mm of wiggle room the other has you press fit the 1mm module into the host/heatsink. The latter definitely has better heat dissipation however it is quite hard to press a 30mm of copper. I am making this post to ask for your (most likely) more experienced opinion on what you think is a good idea for this host.
 





I ordered a laser 301 just to take apart and try and retro fit my own stuff thats still in the mail. Any news on how this has worked for you yet? Id like to see your prototypes too it sounds cool

Be prepared for some glue and a tight fit of the module. Most likely it will be needed to be pressed out.
Those 301's 303's etc. also use a side button switch.
I took one apart years ago without damaging the parts. Just advice but I used a piece of metal tubing "I think from one of those glass tables legs" and lucked out that it fit inside the host and made contact on the edges on the back of the module and cleared the driver.

I had to cut a notch out of the tubing enough to clear the side button insides. I then used a 6" Clamp to press it out. You will probably need a 1" spacer on the front of the host so the module slides in it as thats the side it slides out.
You can easily mickey something to work.

I lucked out before with strange parts working out. My diode press is from a 2$ ebay 532 dpss heat sink. Works great :^D

My dad had some coat hangers with plastic things like you see at the stores for sizing numbers under the hook, they are just above 12mm and when clamped they are a tight squeeze. They are perfect for attaching springs for wiring and keeping pressure. They are a little difficult to keep glued tho, I think I might just use a giant glob of epoxy to the side of it, idk anyways instillation is a struggle. :for when the 12mm module doesnt have a spring on the driver fitted properly to size.

My 301 laser is still in the mail currently. Ill be here when it does for sure, thanks

Imight need to buy a dremel tool

Also, OP, I saw ur laser host is sold out just now. Congrats but theres no pics currently, I really wanna see it

I didn’t even notice people replied to this, sorry. I made 5 hosts, sold 3, kept 2. I ended up closing my store because shopify was too expensive at the time. Now I might start selling them again if people are interested as I am a little bit less strapped for cash. Thank you for taking interest though. Also the ones I sold were tail switch I’m not sure if I should use side or tail switch so please let me know.

Just remember you need a minimum of 20 posts to start selling on here. Mentioning it is already a violation. Just make 13 more posts. Ask how people are doing or something.
 
Guys, I have been thinking about purchasing 301 laser pointer next year.

Should I choose 532nm green or 450nm 1W blue, maybe both of them?

Thanks

The 301s aren't good at heat sinking. I would avoid getting a 1 watt blue unless you are okay with very short duty cycles.

I have several 532 nm ones that do around 80 mW.

A powerful blue laser does not belong to bad heatsinks because it easy to burn the diode.
I appreciate your advice, this means that I will buy 532nm instead of 450nm since I won't need to worry about heatsink and the heat coming from the 532nm diode.

Can yours light a match and cut electrical tape?

What is there to think about?
You can find 301's and 303's for as cheap as $8. Most members start with them and pen lasers.

Get yourself 2 or 3 of them and you just might find that one of them will do 80mW. They range from 40mW to sometimes 80mW+

I'm not talking about the easy narrow laser pens.

I mean a 301 green laser pointer like the picture below.
There is also a 1W 450nm but like @paul1598419 mentioned, the heatsink is not very good.
So I will purchase 532nm sooner or later, just curious and collecting more lasers ;)
