ToC
EE Vision:
Largely agree with Daniel’s Vision
Three main components to EE (Harnessing, Validation, PCB Design)
Possibly have 3 leads consistently, one for each specialty
Weekly work sessions this term (Lots of board bring up and validation)
Need to balance between Learning and Getting projects down
Choose more achievable comp specific projects
Have defined design phase ie Spring term, halfway through fall if needed
Have board bring up and testing in fall and winter term
Have dedicated harnessing person, beg/strongly encourage ppl to start working on harness,
there are houston harness shortening tasks available @Jerry Tian very beginner friendly task
Â

Â
Nice to have:
Smoke Stoppers
6S ESC (TBD)
ZP3 Interface (Done, Spring 2024)
Servo Module
PCB Projects (Design, Bringup)
We should only pursue projects that are very tangible and clearly optimize something. The following are in order of priority and should be pursued by EE for these reasons:
Sensor Cluster (Spring 2024, Fall 2024)
todo
design board with sensors and a CAN node
use case
future vehicles
why
CAN node for minimal harnessing connection of a lot of sensors to the FC
we commonly use these sensors
who
michael botros
ESC CAN Adapter (Spring 2024, Fall 2024)
todo
design
use case
future vehicles
why
CAN node for minimal harnessing connection to the FC
we need to space out ESCs on larger aircrafts
who
Meghan Dang
ELRS Gemini (Next rev) (Spring 2024, Fall 2024) pending assignment
todo
make the board smaller
use case
for competition
why
improved rf link quality
doesn't exist commercially
LED Board Rev 1 (ASAP)
todo
assemble and use
use case
for realism points for competition and cool ig posts
pegasus
future vehicles
who
Parker
ZeroPilot 3.0 Hardware (ZP3HW) (Done, S24)
todo
assemble flight interface board
fix oscillator on primary
use case
for EFS M2 and beyond ZPSW objectives
never be competition viable
who
Â
48V->12V,8V,5V @ 3A BEC (Buck Converter) (Spring 2024, Fall 2024)
todo
design, test, etc.
use case
all future vehicles
why
for reducing the number of power supplies we have on the drone right now
simplify all the power harnessing we have
who
Ishman
Tracking Antenna Initial Concept W23 (Bring up S24)
why
for reducing harness count on the antenna head
todo
combine nathan’s and Michael’s board, best of both worlds
12S Servo Module (Bring up and Validation S24)
todo
assemble and test
add CAN support: Servo Module Improvements
use case
future plane or vtal
why
for spacing out servos
minimizing wire complexity on upcoming airframes
more stable power to far away servos
ELRS Quadversity (Spring 2024, Fall 2024/Winter 2025)
todo
design
test
make smaller
use case
all future vehicles
why
improved rf link over gemini
who
Nolan Haines
GPS CAN Adapter (S24, F24)
todo
make GPS’s work with CAN
use case
all future vehicles
why
allows us to space them more without SI concerns
busability
who
New bootcamper (Omar)
Unified Video System (Spring 2025, Fall 2025)
todo
make video system sit on one panel
use case
all future vehicles
why
improves packaging
reduces harnesses
reduces emi problems
24V->12V,5V @ 2A Buck Converter Board (Already done?)
use case
for ground validation
unlikely to be competition viable
why
fun
12V->5V @ 3A Buck Converter Board (Already done?)
use case
for ground validation
unlikely to be competition viable
why
fun
https://uwarg-docs.atlassian.net/wiki/pages/createpage.action?spaceKey=EL&title=12S%20High%20Current%20Power%20Module (Done, Spring 2024)
maybe viable for competition
needs to offer some improvement on COTS to be viable
validate and test our copy of the COTs for now
plan for the future here, we need to think of exactly what functionality we want and what’s achievable.
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2506883090 (On Hold)
todo
design
use case
future competition vehicles
why
for some integration improvement in the future
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2120089637 (Archived)
for fun
never be competition viable
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2115010797 (F24, W25)
for ground validation
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2246017323 (F24, W25)
for future vehicles i guess but we dont have any vehicles of this size planned
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2250670083 (Spring 2024, Fall 2024)
never be competition viable
for fun
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2250866689 (TBD)
never be competition viable
for fun
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2311651382 (Cool but later)
lots of integration overhead
who: would need to have someone ambitious, shouldnt be pursued for now
Insane ideas that are years out but possible in Daniel’s opinion (and will stay on Daniel’s list of personal projects and if I get anywhere in the next few years I will merge back into WARG projects):
RF Unified Link
HAM band (70cm or 2m)
RF Heartbeat initially, then more comes later
CAN interface to FC
variable airside power, very high power ground side
not started but lots of COTS hardware could be leveraged
More efficient conversion from 48->12
I have started this as a personal project, finishing is a whole nother challenge
fully custom including magnetic
EE Meeting Time
Tentatively Wednesdays @ 7:00 pm
Â
Boot Camp
Mena is interested in reviewing bootcamps
Maybe new roles for harnessing and validation which don’t require completion of Altium Project
Still would require knowledge of PCB Design
Don’t need to complete PCB design bootcamp
Require attendance in 1 or 2 workshops to pass
