DNA with 1200 mah lipo and built in charger

[jmarkus]

working really nicely, so great to have the onboard charger! some inspiration from mamu's tinted volt meter, i decided to cut a piece of anti-static bag and use it over the meter. a nice mirrored accent, but wanna try a nice piece of dark tint on the next one.

i used a single cell 3.7 1200 mah lipo pack
sparkfun mini usb charger board (500mah charge rate)
3d printed box for the enclosure (from a cad model i was using for a different project)
dna chip
clicky low amp switch

Where did you get the embossed battery box?

Where did you find the lanyard attachment?

Looks like your using a double AAA box under the atty and a double AA box for the battery.

Looks great

Are you using a 14500 Lipo?

Inquiring minds want to know.

Awesome quality execution of the design.

the embossed battery box is a 3d print job from a cad model i did. its basically like you said 1 single AA box and 1 dual AA box but its one solid piece that was printed by a 3d printer. im using a single cell lipo pack, not 14500's. not sure where you see a lanyard attachment but there isnt one. .

thanks for the kind words!!

On closer inspection it's the usb input receptacle.

Old eyes, small screen. )

Very beautiful execution


Did you use a 3d printer for the box?

yes, i used a service by shapeways.com to get the cad model printed.
