Week10 Final Project Q&A¶

Who’s done what beforehand?¶

I found several beautiful bedside lamps from fabacademy archives. I like this one and this one very much.

What will you design? & What parts and systems will be made?¶

It will have following parts: * A lamp for the bedside table.
A clock.
A slot with an end-stopper for your phone, it also has a phone charger.
* A rewarding wall with jigsaw pieces, each piece have an LED. * A platform to hide the components.

The systems are:
* clock and alarm setting
* lamp with different color for different conditions
* speaker with different sounds for different conditions
* the phone slot has an end-stopper to detect whether the phone is in or not by weight (easy to cheat it, but it’s OK).
* Jigsaw pieces with leds, which will be turned on when put on the rewarding wall (connected to the copper foil)

What materials and components will be used?¶

The lamp
- Card paper and rice paper by vinyl cutter
- RGB LEDs
- The central part will be made by 3D printer
The clock (it is a part of the lamp)
- Card paper and rice paper
- OLED and 12 RGB LEDs
- 2~4 buttons
The platformer and the slot for phone
- Wood board by laser cutter
- end-stopper
- light sensor
- speaker
- chip, not sure which to use yet. Maybe ATmegaXXX or ESP32
- phone charger wire
- springs
The rewarding wall with jigsaw pieces
- Wood by laser cutter
- LEDs
- magnet
- copper foil

Will buy from taobao.com. Price not sure yet. No more than $80. 【TODO: add BOM here】

What processes will be used?¶

computer-aided design
- 2D design for the surface of the lamp and the clock
- 3D design for the platform, the phone slot, and the rewarding wall
Computer-controlled cutting
- vinylcutter for the surface of lamp and clock
- laser cutter for the platform and the rewarding wall
3D printing
- for the phone slot, the lamp seat, and the platform
electronics production
- PCB design and milling
- copper foil with vinyl cutter
- soldering
electronics design
- design the schema for the lamp, the clock, the platform and the rewarding wall
input device
- end-stopper, light sensor, button
output device
- LED, OLED, speaker (with DFPlayer)
embedded programming
- the micro-controller programming for the lamp, the clock and the rewarding wall
molding and casting
- not sure yet. Maybe will use molding for the phone slot

What questions need to be answered?¶

Which chip to use?
How to set the alarm for the clock? Not designed yet. It can be buttons and use code to handle the logic. But I would like to have approaches with more fun.
How to have one LED in each jigsaw piece, and the lights can be turned on when they are connected? Need to deisng and prototype.

How will it be evaluated?¶

Functional: if it works for different conditions?
Fun: can I have fun with the jigsaw pieces?
Beauty: is the lamp and clock looks nice?
