Last time serving music to all devices was the problem. DNLA looks fine technically but the implementations are poor and ugly generally exposing the architecture to the user.
Bandwidth is a problem. Most ARM chips are cellphone based and skip USB3, SATA, and gigabit ethernet. The i.MX6 is OK but it’s hard to resit the extra 700 MHz of the Exynos. Freescale did a very good job of opening the datasheets though which should be encouraged.
Micro quad copter
Play with something like the Crazyflie micro quadcopter. Advantages are:
- Open hardware and software
- Can fly inside (good for dev, snowy countries)
Positioning is tricky due to the limited lifting capacity and indoor use. Look into indoor positioning like
- IR beacons with ID codes, spinning quadcopter, use the gyro to calculate angles
- IR altimeter. Ultrasonic is heavy, affected by draft?
- Dual camera ground station
Swarms are more fun.
Reversing the fitbit one
It’s a nice gadget but in the spirit of “you don’t own it unless you can hack it”, reverse the USB protocol and extract the step count data over Bluetooth.
Record all the things
Over measure everything. Record data from all the trackers I carry and use like
- Coffee machine
- Time spent using
- Level of activity (accelerometers?)
- Pages visited, games played, shows watched, songs listened to
- Leisure time
- Project time
- Wasted time (incessant checking of hacker news…)
- “Streaks” by geofencing things like the gym and recording if something is visited to plan
- Popularity of artists over time
Could use power draw for devices that can’t be self instrumented.
An easy, cheap way of measuring temperature across a vineyard.
A box that has a year battery life. Waterproof, robust. Replacing the battery on damage is fine.
Use the camera and flash on a smartphone for communication. Photodiode and LED on the unit to reply. Keeps the unit waterproof. Flash the flash for transmit, decode the flash recorded via the camera.
Have simple hand signal checks. Swipe hand past, back, past, and hold to get status. Use interrupting sun or torch on the same light sensor as for phone communication.
Place in the vineyard. Press ‘Record’ on the phone. Phone flashes the ‘get ID’ command, records returned ID. Takes GPS position, records in database with nickname.
- Button: no sealing or custom case
- Custom configuration device
- Custom interface for configuration
- Barcode of ID
Easier Spin. Control Rhythmbox over the dbus API. Have three playlists - Warmup, Respin, and Warmdown. Default workout time that can be bumped.
Clap for Next. States:
- Warmup: means start
- Workout: means pick another song
- Warmdown: means one more workout song
Always shuffle. Never use the same song twice in a run. Record past songs to give variety.
Group songs by BPM/style? Two similar, then move on?
Use a Pulseaudio tap for echo cancellation? Beep at minute intervals for timing?
Use a webcam for gestures? Raise/lower volume?
Bonus points: fit songs within a minute of workout time. Calculate all combinations where |total play time - workout time| < 1 m.
PDP blinking lights
Do a PDP 11⁄20 style front panel with the black glass and 70s purple, use LEDs, drive using a BeagleBone, hook to the internet.
Design and have Ponoko cut out of clear acrylic. Etch the labels.
The I/Os are 3.3 V and 8 mA. Add some tricolour LEDs. Hook into the PWM.
- Multiplex the LEDs. Needs a kernel driver
- Add some switches that do ???
- Hook into the scheduler
- Email notification
- Solar charge/discharge notification
- Adapt the Linaro kernel. Add low power states.
