Changed font size on some capacitors to make it more readable.

Fixed DRC errors in reduced switching board

Preparing Julian's version of Scoutfly to ship out. Fixed a bunch of DRC
errors, but there are still a few. Nothing major. Just some spacing and
routing angle errors.

0bd4bb32 03/25/2012 12:07 am Thomas Mullins

Added motor code for forklift, and fixed analog and i2c code after testing.

Merge branch 'master' of roboclub.org:/home/svn/scouthw

048ed7e1 03/20/2012 10:26 pm Thomas Mullins

Added analog.c for line following and linear pot

Most of the line following was copy-pasted from Colony 3. Still unsure
about prescaler, which used to be 2 for some reason but is now 64.

Fixed a bug in the switching power supply circuit where diode was connect to FB instead of SW for the 5V supply. Also changed an inductor value.

a675468b 03/18/2012 08:17 pm Julian Binder

Made changes that Abe recommended:
Fixed SHDN pin connection.
Changed inverter voltage level from 5V to 3.3V.
Modified PB Controller to have value displayed.
TODO: Address concerns about shutdown timing and switch power loss.

Deleted library that was unnecessary

ba8bd0b5 03/08/2012 06:19 pm Julian Binder

Added a new push button controller circuit. Uses new IC instead of solid state machine because there was no room for solid state machine circuit. Preformed changes that Abe recommended. Routed new circuits. Board should be ready to send back out to kwoo.

8d6c686a 03/07/2012 10:05 pm Julian Binder

Added new switching power supply for 5V and 3.3V supplies. Routed board to include these, and switch.

a8b095dd 03/06/2012 09:51 pm Julian Binder

Added packages to kwoo for diode, dd2pak for switching regulator and switch. Working on schematic for the new power system using switching regulator.

a52b0259 03/01/2012 11:46 am Thomas Mullins

Added code for forklift AVR

twi.c and twi.h were taken from Arduino's library. forklift.c currently
implements i2c slave communication, but no motor control or sensor input
yet.

618ca0e5 03/01/2012 12:19 am Julian Binder

Changed library to conform with voltage regulator package. Redid routing to conform to new package. Add heat dissipation area. Still need to check that this is correct. Also fixed cap values for voltage regulators.

2d30dad9 02/23/2012 09:59 pm Julian Binder

Added simple power circuit to the scoutfly reduced board. Using 2 new LDOs to regulate down to 5V and 3.3V Also removed the charging circuit, gas gauge, push button controller. Removed charge led.

b3ec400f 02/23/2012 01:20 pm Julian Binder

Added forklift subdirectory to scouthw. Contains the schematic and board files for the forklift accessory along with a library containing the motor driver.

b31bb146 02/23/2012 12:59 pm Julian Binder

Added a new library with a voltage regulator part. I forgot to add the Name and Value so i will do that. I also added the start of work on the reduced feature set scoutfly.

Did some wire routing and part moving.

45a31aca 02/06/2012 11:29 pm Thomas Mullins

Mostly finished routing the regulator circuit

7f9670e3 02/01/2012 09:59 pm Thomas Mullins

Made a little progress on the gas gauge routing

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

Fixed angle errors in Scoutfly power update.

Scoutfly power update now passes DRC.

54e8c05e 01/17/2012 12:42 am Abraham Levkoy

Moved power parts in Scoutfly layout

Moved parts for new Scoutfly power circuit from edge of layout to their
(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

Added files used for manufacture of power test board. Removed copy of
power test board files used to run autorouter, as it will not be useful
now that manually routed version has been manufactured.
