Generic robotic base with RSV2 Prt 4


Part 19

Fabricating the 9v , 6v for driver and brains, and  6v and 3v for laser p/s for RSV2

Ok, I have breadboarded the 12v to 9v,6v  and 3v using 3 LM 350T variable voltage regulators, [This is a bit of an overkill] as LM 317's would do. Here are a few pics of the layout and a full how to will be posted when I have checked out RSV2's circuits before I decide on the exact layout of the P/S.



This was a single setup for 9v.

 



This setup is getting closer to the final stage, First LM 350T showing 9V output for RSV2's driver board and motor network.

 



Second LM 350T showing 6v output for RSV2's brain.

 



Third LM 350T showing 3v for green shoulder laser.

 


 

A closer look at the P/S, Note the blue led on the left, This is for the 12v input indicator and the green leds are for the output indicators. Aslo so note here in this setup that I have 5k pots to find out what the fixed value resistor to use, The reason I use a fixed resistor in the final design is I do not want the pot to move and cause a higher voltage on the RSV2's circuit, so a fixed resistor will prevent this, even though I could use hot melt glue on the pot.
Once I am satisfied with the design I will do the final P/S on perf board.

Well here we go, I have changed the design to 6 LM 350 voltage regs each consisting of a circuit similar to the above one. In the pics above you will notice I originally had 9v and 6v for the driver board and brain of v2 but since have changed this to six separate circuits consisting of 1 x 9v, 2 x 6v, 1 x 4.5v, 1 x 5v, 1 x 3v  The extra 3v and 6v are for my 35mw green laser and 200mw red laser. The 1 x 4.5v and 5v are spare for later projects.


 

6 LM 350T voltage regs

 




6 regs soldered to board.




Power led and + leads to regs.




9v and 6v first stage soldered.




4.5 and 5v  second stage soldered





A closer look at the two stages.




Third stage 3v and 6v laser supply for 35mw green and 200mw red lasers.

Final lay out of power supply system with the two laser output sockets.

 



Finally powered up, all systems go. I MAY HAVE TO INCLUDE HEAT SINKS ON ALL OF THE REGS Otherwise they may get hot when V2 is using all of his motors particularly when under load.


Part 20   

 Installing RSV2's power supply to robotic base

 


RSV2's power supply now fitted to my robotic base and fully working, You can see the power LEDS on indicating the output status.

 


 


 

 A closer view of my power supply, This will be used to power V2's 9v driver and 6v brains, first two regs, The second two are for 4.5 and 5v spare for other projects, and the last two 3 and 6v for my 3mw green and 200mw red laser's.
