3. Design problem How can you charge your device? Remote location
Camping, cabins
Devices run out of battery power
How can you charge your device?
Use devices in the case on an emergency

Cannot connect to a grid
Can be used in remote locations
Alternative way to produce energy
 JEN

5. Alternative ideas Solar Powered Chargers Stirling Engine
Body Heat Chargers
Portable Battery Packs
Crank Chargers
Marty wants to do this slide
The HomeStove converts heat from the fire into usable electricity giving owners an instant power outlet.

7. Design process : Electronics
Voltage needed was known: 5V per USB port
7805 Regulator Chip  Regulates voltage down to 5 V
1N4001 Diode
Fujitsu battery pack circuitry
3 USB Ports
4A1498 Fuse Switch
Cooling fan
Micro-USB alternative charging
5V for each USB port , USB ports require 5V
Researched data sheet for 1n4001 diode states that it can handle up to 50V and a typical phone battery is only 5V, this gives us a factor of safety of 10
Dr. Comeau suggested we implement this regulator chip into our design
Battery pack enables us to use the device without anything plugged in, battery pack stores power
Max. current for all 3 USB ports is 3 Amps. Which is the max. output of the battery. (data sheet, safely output 3A without being damaged). Total wattage is 15W total.
Safety label : don’t use anything more than 3Amps / 15W (I.e. don’t use splitters)
Fuse protects battery from being overdrawn from (battery damage, would heat up)
Subcontract fujitsu battery circuit and use their circuitry for the battery pack
Marty wants to do this slide
Switch would trip when when too much current; rated at 3A

8. DESIGN PROCESS: piston system
Double work  our piston is getting pushed from both sides, dependent on the position of

9. DESIGN PROCESS: BOILER
Pressure Gauge
Top can be unscrewed
Refill the boiler when water runs out
Safety release valve
User can depressurize the system
Rated for 35 psi
1.5L capacity

10. Design process: materials
Casing Materials  Zytel Plus Nylon Resin
Melting temperature 283°C
Hose Materials  White Silicon Rubber Tubing
Maximum temperature 260℃
Fiberglass insulation divider  R-13 Kraft Faced Insulation
Face insulation uses kraft paper vapor barrier to control moisture transmission
Aluminum, Copper
Various uses in steam engine
Stainless Steel

14. Problems encountered Hard water deposits Number of USB ports
Cooling electronics
Boiler design
Cylinder-Piston design
Insulation
Had problems with the boiler design; spoke to an engineer
BREANNA
Hard Water Deposits : make the device easily disassembled so it can be cleaned;
Number of USB Ports: Had a difficult time deciding how many USB ports we wanted to have; the fujustu battery circurt data sheet says we can supply 3A to the USB ports. Therefore,
Cooling Electronics: wanted to fully ensure the electronics did not get too hot because of

15. DESIGN PROCESS: SAFETY
Keeping electronics dry
Fiberglass insulation between electronics and piston system
Warning labels
To ensure user safety
4A1498 Fuse Switch
Trips when too much current is drawn from USB ports
Condenser is insulated
Too avoid overheating
Hose Length
Ensure hose are long enough so device does not overheat
HOSE LENGTH 2FEET OR GREATER
JEN
Fuse switch is to protect battery within circuit
