    Red dot laser brick

    posted by tnvd on 06/20/2013 Certified Owner

    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 figur...
    Cons:
    As usual; no documentation. Well wrapped, but the brass laser mount was creating shortcircuit to the blanc wires. The brass led...

    posted by jurpie on 06/16/2013 Certified Owner

    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. Need to adjust Lens man...

    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.

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Very cheep. Easy to connect. 5v supply easy to integrate in a circuit. Good pointer dot. Does not get hot. Does its job xD. Very good for microprocessor interfacing. Low power.
    Cons:
    Laser pointer not aligned properly with pcb and the dot is not a straight line. Pcb contact and wiring are all bare, can be eas...

    5 mW red light laser with focusing lens

    posted by dirkm5 on 11/04/2012 Certified Owner

    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....
    Cons:
    Had to bend wires between circuit board and laser module to eliminate the short circuit.
