Hello to anyone interested in NUBM35 portable laser.
Wanted to share some information that might be useful regarding this topic.
I manage to build a sexy looking version of NUBM35 portable laser inspired in the design of StyroPyro and with the BIG help of Giannis_TDM. Big thanks to both of them! You can see the end result here:
If you are interested in more information, you can download the FULL step by step instructions on how to make it yourself here:

The design features stable dual driver made of LM338s. One circuit for 5% power or 1.5W (positioning on target beam) and another 100% power or 70W. The drivers are controlled by momentary buttons connected to MOSFETs. There is also a general switch to turn on the device, as well as thermometer and voltmeter. All the power is supplied by 125C peak power Turnigy 4S+5S lipo batteries connected in series. The charging is done by opening the lid and charghin the LiPo batteries with regular LiPo charger.
The heatsink has 105cm3 of aluminum which means that the temperature increase at a rate of 1,2 C for every second.
This equals to 10s on / 20s off duty cycle . This way the temperature is kept under 40 degrees C.
Runtime is also limited- between 3 and 5 minutes on max power (depending on how low you want to run the batteries)
Of cause this is not great, but IMO having a 70W sexy pocket BEAST with all the features you need (thermometer, voltmeter 5% and 100% modes, general switch, etc...) far exceeds the inconveniences. Finally, I built this almost an year ago and so far runs flawlessly after 35-40 charges.
I hope this information can help anyone that is trying to build something similar. Feel free to ask, if you have any question.
Alex
PS:
If you are interested in purchasing the aluminum 6082 host or the assembled version, please feel free to do it here:
https://truelasersaber.com - (BTC and Credit/Debit cards accepted)
The total price for the Host is 195$ and you will have to spend another 260$ for the rest of the components (Nubm35, batteries, etc...) which I believe is very competitive price for 70W "laser pointer"
The price for the assembled and tested version as of now is 395$ (only without batteries and Laser diode, since there Is no way this stuff can cross borders fully assembled). You will jus have to spend an additional 230$ for those two components and attach them which should take you around and hour of work. This process is well described step by step in the instructions too.
