Positioned some of the components in the gas gauge circuit, and
routed a few wires.

d6199bd9 02/01/2012 02:51 am Abraham Levkoy

Started routing charging updated charging circuit

Routed some of charging circuit in updated Scoutfly. Modeled part
position after that on power test board. Moved diode and capacitor out
of the way to get inductor closer to charging chip. This will make it...

51698c42 01/25/2012 09:55 pm Abraham Levkoy

(very) approximate final locations. Changed the battery and charger
connectors from vertical to horizontal Molex connectors.

b7bdc50b 01/16/2012 03:17 pm Abraham Levkoy

Added Scoutfly files with new power circuit

Switched Scoutfly from old power circuit to new power circuit from power
test board. Did this in a new file so that, if the power circuit turns
out to be a failure, other changes made contemporaneously to Scoutfly...

14d1e574 01/15/2012 06:51 pm Abraham Levkoy

Added power board CAD files, deleted autoroute

Turned on "always vector font" in Eagle options

While editing power test board, turned on the "Always vector font"
option in Eagle. Honestly, I might have done something else to the
silkscreen, but I can't remember what. I'm pretty sure I didn't mess
with any of the actual components.

cec2aa8e 11/07/2011 08:32 am Abraham Levkoy

Fixed silkscreen ugliness in power board

Went through layout and changed ugly names and values to good ones.
Moved text off of vias and pads and out from under things. Deleted
giant, useless USB port and ISP header labels. Added description, date
of design, and attribution in corner.

d2b7d4f7 11/07/2011 06:02 am Abraham Levkoy

Widened battery and charger traces

Widened to 20 mils some traces that come from the battery and charger
connectors, because they carry higher currents.

f01b49cf 11/07/2011 05:46 am Abraham Levkoy

Added ground poly under charger IC

Added polygon under LT3650 IC and updated it to new device from kwoo
library. It now has effectively both a ground pad and a via. Slight area
of no contact right around via may be unavoidable.

38c9810d 11/07/2011 05:28 am Abraham Levkoy

Widened traces, moved gas gauge power supply

Widened traces that carry VBATT. Lined up decoupling capacitors for LDOs
with their connected LDO ports. Rerouted various traces ripped up during
execution of previous changes.

increase trace width for power inputs and decrease unneccessary loops.

1637ab5d 11/07/2011 03:41 am Abraham Levkoy

Changed center ground pad for DS2786 and LT3650

Changed ground pads for packages 10MSOP and 12TDFN to have through-hole
pads on the bottom instead of SMD pads. Updated power test board to use
the new DS2786. Drew a polygon of BATT_GND around center pad. Not sure...

1bc70a1f 11/06/2011 07:12 pm Abraham Levkoy

Updated power test schematic

Based on feedback from Kevin, added a pullup resistor to !PWR_INT and
decoupling caps to the LDO providing VCC.

Also changed the ground signal on the gas gauge LDO from GND to
BATT_GND. Kevin pointed out that having BATT_GND as the ground for the...

Minimized possible inductive loop in power board

Moved trace driving FAULTLED to minimize area of inductive loop in
vicinity of charger.

e5134b5f 11/06/2011 09:21 am Abraham Levkoy

Finished power board routing (first attempt)

Routed all signals on power test board. There are no airwires, and the
board passes DRC. I believe I have kept the inductive loops near the
charger pretty small, but they could probably be improved. I also made...

aa7ee9ae 11/06/2011 08:33 am Abraham Levkoy

Finished routing signals connected to AVR and FTDI on power test board.
Started routing signals attached to pushbutton controller.

8b6cb5d4 11/06/2011 01:56 am Abraham Levkoy

Routed USB circuit and most of AVR on power board

Routed most of the signals connecting the USB port, FTDI chip, and AVR.

1a5559b0 11/05/2011 10:46 pm Abraham Levkoy

Changed USB port drill holes back to spec

Looked at mini USB port with Dan. Observed that corner drill holes are
supposed to be multiple drills right next to eachother. Decided to
change holes back to specfied radius and ignore long hole for now.

30d533fe 11/05/2011 07:05 pm Abraham Levkoy

Preliminary power board placement complete

Placed all parts on power test board in what I believe will be their
approximate final locations. No routing done yet. Board probably won't
get bigger, because I left room to grow.

9180be39 11/05/2011 06:17 pm Abraham Levkoy

Partial placement of power board

Placed AVR, FTDI chip, and USB port on power test board, along with
their accessory components. They are probably pretty close to their
final resting place but may move a little bit later.

00c7cdb1 11/05/2011 05:29 pm Abraham Levkoy

Changed IO voltage for FTDI IC on power board

Changed VCCIO input for FTDI chip on power test board from USB_VCC to
internally generated 3.3V signal. This should have no power effects, but
Kevin suggests that it may make the chip behave a litte bit nicer (not...

344a6bf3 11/05/2011 04:00 pm Abraham Levkoy

Fixed ERC errors from unconnected wires

Some wires created in the previous few commits were not actually
connected to the pins they ended at. I fixed them.
