    Involvement:General (knows how to use it) - Ownership:1 week to 1 month Pros:Good soldering. Nice to play with (after paying some attention to the wires and the brass piece) This is an laser led mounted on a small PCB. There are 3 pin connections which are not documented (I get used to the DX non documentation). So you have to figure out which p... Read more

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month Pros:5V Laser module works great no resistor needed. Works perfect with Arduino or other microcontrollers. I just connected 5V to the S and GND to the - and it works Cons:There is a small resistor soldered onto the laser module. Not that great quality, but it works perfect.... Read more

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month Pros:It's cheap, easy to connect and use, you don't need any resistant or so, it don't get hot. Cons:I don't find one so far. Others said it can be easyli short circuited, but I don't have that problem. OtherThoughts:It's pretty good for this price. If you need an easy contr... Read more

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month Pros:This laser LED looks similar to SKU 133778, rated to be 5 mW. To operate with a 5V power supply, a series resistor is required. I used a series resistor of 1.2kOhhm, resulting in 2V over the laser and a current of 2.5mA, resulting in 5 mW power dissipation. Connect grou... Read more

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week Pros:Cheap and ready soldered laser. Cons:Laser is not so bright. Can not be seen good after like 4 meters. The spot seems a bit scraggy. OtherThoughts:As with all DIY parts on DX there is no manual. So I found out (searched the web) you have to wire minus to the pin labeled &... Read more
