ULTIBOX : Ecig Boost mod with lcd screen , 18650, Constant power. OPEN SOURCE

I love this case. I received all my components. I am waiting PCB to start playing .

LOL Great minds must think alike, same concept:


Only problem I can see is that the battery is literally sitting on the board, so in this case the USB port would be at an angle. Current design:


I do like the design, but the PCB would have to be setup so the battery is in the center of the board to line up the USB port. Like so:


The LCD would also need to be angled to match the angle of the housing. This way the USB port is straight as is the LCD panel to the housing.

Hello Scub,

Yes, I like this design.
But, I can not separate the screen from the pcb. I use a "Zebra" for the link. The USB connectors can be not aligned, it's not very important.

Ok so how about a clam shell design?

Easier to assemble and take apart.

Not easy to build. I think the first is better. I can do a lot of pictures next week when i will receive my boards.
It will be easier to imagine the perfect box.

Nice work, Dan...and better tools than I have.

Can you suggest a 3D modeling program that is in the public domain?

Google has a free program called sketchup that's worth checking out

A wonderful 3d program that's free and open source... Blender.

Why not run the PWM at say 20Hz rather than 100s KHz and not bother with capacitive smoothing; more efficient and less noise. The DC equivalent can be calculated. Am I missing something ?

I am just using the emachineshop.com free cad software, and doing screen shots.

CapeCAD, QBass, Dan -

Thanks for the info on the programs!

I use a boost to step up the voltage (power). At low frequency, the size of the components increase but switing losses decrease.
I agree with you, for a simple pwm (no inductor, step down), no need capacitor but i prefer to use 20-30Khz frequency .

Pailpoe, nice to see you back
When you're finished, will you post Eagle project files, instead of images? And the source code for PIC?

And... really thank you for choosing both the PIC and the Eagle

 

[pailpoe]

Yes, of course.

 

[pailpoe]

The PCBs are ready to ship. I hope to have my PCbs this Tuesday.

 

[emonty]

always good to hear, shipping....we all enjoy those moments........

 

[QBass]

I would think the receiving to be far preferable to shipping, but then my mailman is a certifiable ninja that can sneak a 'package is waiting at the PO' pink slip into the box even while I'm attentively awaiting his arrival!

...have a great Tuesday, 11 October!

I'll be yet another to welcome you back 'pailpoe'. It's been a while since I've been on the French forum.

I take it from the earlier posts there was not another run of the Modulra? I was on the second list of 50. Money is tight for me so maybe it's for the best

Either way, good luck on this one. I anxiously await the videos.
