Sadly the above said "fission" which means that no space agency will authorize near-earth use of the engine... it can still be useful for deep-space transfer burns but we really need fusion engines that don't leave a radioactive wake
This is quite simple to fix through some very basic regex run on thread creation or via a much-needed CAPTCHA on user registration (just don't allow audio-only CAPTCHAs, those can be easily bypassed with basic machine learning nowadays).
You could even do a one-time thing where every single...
Wow this boss guy must have a lot of profit to be able to buy up so many of your employers lol
Sometimes its the "a$$holes" that go on to become the best businessmen and ultimately excel in our capitalist society 🤑
Yeah membrane-based and piezoelectric fans are also cool, but I think fully solid state fans relying on ion flow stuff to generate wind are the end game
I can 3D print a custom heatsink-module out of aluminum for now, its actually remarkably affordable for small prototypes.
The main issue is that I can't cheat the laws of physics, small laser modules and big fans don't really mix. If only there was a way to have a fan with no moving a parts or...
I've always wanted to build a high-power laser that doesn't feel like a blunt force weapon when I hold it
Perhaps I could make use of one of those <2cm diameter fans to make something with an JD-851-like form factor.
Alternatively, if I wanted to go even smaller perhaps I should look into a...
Hello LPF, I just wanted to hopefully get some insights before pursuing this project further: I want to take an NUMB44 diode and place it into the smallest possible enclosure while retaining a 15 seconds duty cycle (with plenty of cooldown time after).
Does anybody have experience heat-piping...
This tech could even be used to power the next generation of spacecraft, maybe even inertial confinement fusion engines resembling the hypothetical Daedalus engine: https://en.wikipedia.org/wiki/Project_Daedalus
Holy smokes, if this proves to be real we might see some extremely powerful and cheap lasers come to market in the coming decades!
Think about a house-scale fusion reactor one day
I would recommend saving up some money and getting this guy: https://www.laserbeelpm.com/laserbee-ax.html
Lasers are an EXPENSIVE hobby, so please quit while you are ahead if you cannot afford to set aside $200/month. I myself have put this hobby on hold in light of the recent recession forming...
Most likely a DVD burner laser diode. Start at 2.5V and really low current (~1 mA) to identify the laser color/frequency and polarity (if there is no light at all the polarity is wrong or diode is fried), and adjust voltage accordingly (2.5V usually for red/infrared, 4-6V usually for blue or...
Just saw these on eBay: https://www.civillaser.com/index.php?main_page=product_info&products_id=3561
Is the divergence any good on them, could it be comparable to say a Sharp GH0637AA2G?
If there are any new red lasers on the block, I want to try doing a revised better beam quality build
