DNA200 build

Good to see some more activity on here.

Here's my latest. Spalted beech body, bog oak (from the colour probably about 7000 years old) deck and buttons.





I've had the DNA board since it was released, just hadn't gotten round to putting it in anything.

I'm working on an ARM based PWM board too.

Beautiful work doob. Thanks for posting it.

Very nice mr doobe.

The 2S/3S charger you were working on, did you ever get that fully sorted out and working?

No I've been crap in that department (along with many other departments) . The charger needs some hardware debugging, I think I probably just need to move some pullups, I should have put the prototypes on a larger board. I will get round to it though.

I was chatting with Mark from SmartPWM (he's a member of of Breaktru's forum http://breaktru.com/smf/index.php/topic,1619.msg20749.html#msg20749 https://www.facebook.com/groups/416421905210775/) about the possibility of series charging. Showed him your post from Ukvapers about the board you were working on. Thought perhaps you guys might like to exchange ideas or collaborate. All the microcontroller stuff is over my head, but both of you two guys seem to be at around the same level as each other.

Pardon straying off topic from your original post...

The idea behind the little standalone boards was to try to avoid using a booster circuit. On my arm boards I'm going to use a booster and balancing taps controlled by the MCU. The ARM runs at much higher frequency than the AVRs I've used before so can use smaller components for the booster.
