Hackaday Links: December 8, 2013

December 8, 2013 by Mike Szczys 4 Comments

Let’s start off with some high voltage. Here’s a sweet Jacob’s Ladder build from [Robert]. The site hosting his short writeup has been up and down for us so here’s a cache link.

Speaking of high voltage, if you want to switch mains with your project [Tom] has a breakout board for cheap mechanical relays. [via Dangerous Prototypes]

[Dario] made his own version of an electronic Advent calendar [translated]. There are no numbers, you must solve the mystery of the flashing LEDs to figure out which package goes with each day.

If you ever work with lighted arcade buttons here’s a guide for swapping out the light for an RGB LED. This hack uses through-hole LEDs. We’ve actually seen a surface mount hack that includes a PCB to mimic the old bulbs.

Next time you stay overnight at an event you can give yourself the best view in the campground. This tiny little camper was mounted on a scissor lift! That first step on the way to the Porta Potty is a doozy! [via Adafruit]

[Žiga] was nice enough to demonstrate this smart-watch hack by displaying our name and logo (we love pandering!). It features the MSP-WDS430 which is a surprisingly stylish offering from Texas Instruments. In addition to analog clock hands it has an OLED display driven by the MSP430 inside.

Here’s a quick PIC-based metal detector which [Nicholas] built.

And finally, [Chet] saw the oil tank level sensor we featured this week. He built a nearly identical system earlier this year. The oil level sensor works in conjunction with the custom thermostat he built around an Android tablet.

Astrosmash Style Video Game As Sony SmartWatch Firmware

Here’s a firmware hack that brings a video game to the Sony SmartWatch. It’s pretty impressive considering the limited screen real estate and the fact that it has to be shared with the touch input. But we find it equally impressive that a game of this quality followed so quickly on the heels of Sony announcing the ability to make your own firmware for the watch. The speedy development is thanks partly to the community driven effort to hack the Arduino IDE to load sketches on the watch.

The advent of this IDE hack means that taking your Arduino sketch writing abilities to this hardware now has a fairly low learning curve. And reading through [Asier Arranz’s] game code will make it even easier. He calls his game Star Wars but it reminds us more of Astrosmash. There’s a little green semicircle which is your ground-based defense vehicle. You need to fire the laser to shoot falling items out of the star-strewn night sky while also collecting power-ups that fall to the ground. Game play video is below.

Just remember, if you come up with a cool firmware app for the SmartWatch we want to hear about it.

Sony SmartWatch Running Arduino Sketches

Well that didn’t take long. We just heard last week about the Sony inviting firmware hacks for their SmartWatch and here’s an early example. This image above is an animation running on the watch. It was written as an Arduino sketch which runs on a custom firmware image. [Veqtor] wrote the sketch, which is just a couple of nested loops drawing lines and circles. The real hack is in the firmware itself.

[Veqtor] took part in a workshop (translated) put on by [David Cuartielles] which invited attendees to try their Arduino coding skills on his firmware hack for the watch. It implements an Android parser, but the development is in very early stages. Right now there’s zero information in his readme file. But the root directory of the repo has a huge todo list. Dig through it and see if you can fork his code to help lend a hand.

Learn more about the SmartWatch firmware from the original announcement.

HackIt: Sony Invites You To Hack Its SmartWatch Firmware

June 14, 2013 by Mike Szczys 63 Comments

This is Sony’s smart watch, which has been around for a while now. It’s designed for use with your Android phone, and has always included an SDK that allows app developers to interact with it. But now Sony is taking it one big step further. They’ve published everything you need to know to hack your own firmware for the SmartWatch.

The navigation scheme for that articles includes five menu items at the bottom which you’ll want to dig through. The most interesting to us was the one labeled “SmartWatch hacker guide”. It lays bare the hardware used in the watch and how it’s peripheral component connect to each other. This starts with the STM32 (ARM) microcontroller that drives the watch. It goes on to document how the screen is addressed (SPI1) including the pin to turn it on and off. The same goes for the Bluetooth, accelerometer, buzzer, and touch sensors.

Firmware is updated via USB using Device Firmware Upgrade (DFU) mode. We don’t don’t see any way to connect an on-chip debugger. We searched to see if there is a JTAG port on the circuit board and it sounds like getting the watch apart without breaking it is pretty tough.

Now that you don’t need to stick to what Sony had planned for the device, what do you want to do with your strapless wristwatch?
