Yes correctly said. Love working machines.

Thank you Sir.

I made another heat sink especially for the 50mw green module to suit 502b host.

:thanks:

Thank you so much sir. Iam very happy seeing nice comments.

Not at all. I love 502b host. It is very nice. I am loving it.

Thank you so much for the complements. I am happy.

Hello everybody, I have put one more step forward in the journey of laser making my own heatsink using my new lathe. So my build is having my own heatsink my own buck driver with reverse battery protection. My final product. Working very good.

Thank you for answers. I tried to wrap all the parts in news paper double layer and my body touch is still affecting it.

Hello, I have made EMP which will light the florescent lamp easily. My problem with it is. it only works if the wire from rf transistor's collector to one end of coil is longer. if i shorten the wire and my hand touches the battery it wont work. but if i extend the wire even i touch the...

I used pchannel mosfet. yes physically making it impossible to fit is difficult in the case of lithium round cylindrical batteries unlike 9v battery. even though 9v batteries have different type of connectors for +ve and -ve while inserting we still make a mistake by touching them wrong side...

Yes of course. Regarding the driver i used mosfet to protect the driver from the reverse polarity. all the parts soldered on the board is by using torch which was difficult but i made it. i dont have soldering station. i will quickly buy one once i get some income. and regarding the host...

I was asked by one of my friend to make buck driver with reverse battery protection. so i modified the same buck driver which i had posted earlier and when i gave it to him he was happy. 1. Full set of c8 flash light parts with my buck driver. 2. This is the driver 1.5A 3. Back side of the...

Thank you for your comments. I have tested it and it is working very good. i am making another version of it with reverse battery protection when i finish that, i will upload some images again. and regarding chip i am sorry i cannot tell.

You have to build a dummy load. (It have many threads about it you can search and make one on your own self) then attach the driver to the dummy load and turn the potentiometer until you get your desired current. If there is no potentiometer then you might have to change the sense resistor. i...

Finished Product. Finally felt very happy. Going to test now.

This is my third laser pointer. i used m140 diode and custom driver which is made to supply 1.6A current. Heat sink is made from aluminum. single lens glass lens. and c6 Host.

yes it looked very bright and nice beautiful. it is 2w laser 445nm. Everybody from other streets started to shout seeing it. it was amazing.
