Cricket DNA20D

[mamu]

Aluminum case 3.54" x 1.25" x 1.25" (90mm x 32mm x 32mm).

Cricket has 2, 1200mAh 15A round nano-tech lipos for a total of 2400mAh, 36A.

I used the transparent material for the display frame/cradle.

This is it - I'm hanging up my soldering iron and taking a looooong break from modding.

Size comparison with some of my other DNA20D mods...

Where can I get one? Simply beautiful!

Very nice!..

Where did you get the case and firing button from, Mamu?

Very nice. You keep making them smaller and smaller. Next you will make a DNA20 mod out of a small match box.

 

[Roccov]

Every time you show a new mod I like it better than the previous one. Well, the streak continues. Very nice work!

Do a google search for "Aluminum Electronic Enclosure 32x32x90mm".

For the fire button, search ebay for "16mm pushbutton switch dome".

Another great looking mod by mamu........guess we just can say that modding is in your dna......(pun intended).... way to go gal.....

 

[bapgood]

Don't be a stranger.....We all can still benefit from your experience!!!

Oh....and another great mod

 

[itsrayray]

It is beautiful!

The 510 isn't raised, it's the drip cup. I imagine if you want the 510 flush with the top of the box, you could just skip the drip cup.

Hi Mamu can you pls. pm me want to ask you some thing thanks...

Hiya Mamu,

I am building a DNA box mod similar to this in that it has a top and bottom cap vs. a cap on the front or back.

My question is: Did you use some kind of tray to mount everything on and then slide it into position inside the enclosure, or did you "stuff" it in there and then epoxy?

Thanks!

No tray. All parts are positioned individually inside the case, then each epoxied in position.

Thanks Mamu.

For my first build attempt I went with a case like this:

It is a split body case so very easy to work with. I've already got all my switches, batteries (I went with turnigy round lipo 1200mah), 510 connectors, DNA and charging pcb. I also bought a selection of your screen cradles from shape ways. Well, yours and Baps I should say. Great job on those by the way.

The only thing that has me perplexed at the moment is how to mount the DNA board itself. I could of course used double sided tape but I'm wondering if that will hold it firmly enough. I don't want to epoxy it in case it ever requires servicing. I'm surprised Bap didn't do up a cradle for the DNA board as well as the screen. Perhaps it's time for me to brush up on my solidworks lol.

I'll be sure to start a new thread once the build begins. I can't thank you all enough for sharing your knowledge and experience. This is going to be a lot of fun!

 

[brawndo]

that is amazing!! Any pics of the good stuff? The guts

Whoh just saw that it doesn't slide out like the few enclosures I've seen like that. It must have been a pita!!!

 

[Azmo]

What type of solder do you use on the board? I think the stuff I got is too thick because it takes a lot of heat to get it to melt.

 

[mamu]

I use 60/40 rosin-core solder (0.032" diameter) and a Weller 35 watt iron. I also apply a dab of rosin soldering flux (I use the tip of a toothpick to apply the flux) on the holes on the board before soldering a wire into the hole.

Double-sided tape won't hold the board well enough in place to protect the display if the board should bump into it if the mod gets dropped or takes a bump. Better to use foam tape.

Or, what I do is use gel epoxy - I apply a layer to the back of the display (also all around the frame/cradle inside the case to adhere the frame/cradle to the inside of the case), let that dry, then apply a layer on top of that and adhere the transducer on the board to the top of that. When it's dry the board won't budge at all in case the mod gets dropped or it takes a bump. Gel epoxy is easily softened when applying heat so the whole works can be removed without damage.

Hot glue does the same thing as gel epoxy, but hot glue gets gooey and sticky when you heat it to soften it, gel epoxy doesn't - it just gets soft and pliable.

 

[Tanrichguy]

Gel epoxy it is then. Thanks! Just waiting on the screen cradle and I'll be ready to build.
