yes but when i get into more high power stuff i will need better goggles + i do not trust a pair of £5 goggles, the ones on ebay are more expensive

yes i did and i have 17ohm resistors so i will use them

So i am going to buy a pair of eagle pair survival laser goggles. However i live in the UK and shipping to me cost £11 ($15) which is quite alot. I would like to know if there is anywhere for me to buy this laser goggles in the UK without me have to pay an exorbitant amount of money for...

Laser diode wants <75ma

£33 is quite a lot for me

do you know where i can get cheap-ish laser goggles for 405nm lasers (i dont have much money for expensive ones from survival lasers)

So to build my driver i am going to use a LM317 and i also need a resistor to connect adjust and Vout however i am unsure how to calculate what resistor i need btw i am using a 50mw 405nm laser diode.

ive found a driverless 405nm 50mw laser diode which i will use as my first project, do you know why i would need a capacitor? and i really need a way of getting blue blocking goggles. the problem is they are all like above £30 and i dont have much money so i need a cheap but reliable blue/violet...

So for my first laser i just want to build a simple <100mw laser and i would also like to build the driver as well because making one without a driver is too easy. Anyway I'm looking for a laser diode in this range however all the listing on ebay (for me) usually have drivers included unless...
