TI Sports Watch For Hacking

November 25, 2009 by Mike Szczys 60 Comments

How would you like to have a 3-axis accelerometer, pressure sensor, temperature sensor, RF wireless, and an LCD screen in a development package? What if we told you that you can have it in the form factor of a wristwatch offering from Texas Instruments? How much would you pay for such a device? Quit guessing, you can pick it up for just $49 with an estimated delivery in mid-February of next year.

Our tip-line has been packed with emails about this since it was announced on Monday. The device ships with the firmware to serve as a sports watch with heart rate monitor. The price is pretty good just for that functionality but this package also includes a USB programming and emulation dongle so that you can develop your own firmware. It looks like the included development software is written for Windows but we’re hoping you can get it running on other platforms as well.

The LCD is a segment display, so you won’t see DOOM running on board. That said, we expect your first project to turn this into a wireless controller using the buttons and accelerometer.

STM8S-Discovery: Microcontrollers Reach A New Low

November 23, 2009 by Phil Burgess 223 Comments

A complete microcontroller development kit for little more than the cost of a bare chip? That’s what STMicroelectronics is promising with their STM8S-Discovery: seven dollars gets you not only a board-mounted 8-bit microcontroller with an decent range of GPIO pins and functions, but the USB programmer/debugger as well.

The STM8S microcontroller is in a similar class as the ATmega328 chip on latest-generation Arduinos: an 8-bit 16 MHz core, 32K flash and 2K RAM, UART, SPI, I2C, 10-bit analog-to-digital inputs, timers and interrupts and all the usual goodness. The Discovery board features a small prototyping area and throws in a touch-sense button for fun as well. The ST-LINK USB programmer/debugger comes attached, but it’s easy to crack one off and use this for future STMicro-compatible projects; clearly a plan of giving away the razor and selling the blades.

The development tools are for Windows only, and novice programmers won’t get the same touchy-feely community of support that surrounds Arduino. But for cost-conscious hackers and for educators needing to equip a whole classroom (or if you’re just looking for a stocking stuffer for your geeky nephew), it’s hard to argue with seven bucks for a full plug-and-play setup.

USB To Serial Adapter

November 16, 2009 by Caleb Kraft 21 Comments

[Spikenzie] is at it again. This time he’s posted a nice USB to serial converter. He points out that you can buy a USB to serial adapter pretty cheaply, but sometimes you want this functionality built into your project enough to justify the greater cost. In those cases where you want to integrate it, this is an elegant solution. This design was made to be fairly compact and still usable on a breadboard. As usual, you can download the files from his website. If his work looks familiar, it’s because we’ve covered his work several times before.

Hackable Geiger Counter

SFE_Geiger_Counter

[Aaron] A.K.A. [A1ronzo] at SparkFun has put together a hackable USB Geiger Counter. In his tutorial, he gets the Geiger counter to work as a random number generator. Later, he analyzes and discusses how well it works as a random number generator. In the past, we have seen a number of radiation detectors hacks such as the Mr. Fission digital Geiger counter, a count accumulator, and a Polonium detecting pen, Besides our inital thoughts of speeding up the number generation, and using it as a special character device, what else can you come up with to do with this device?

We’ve been watching the development of the snega2usb since it’s debut on Hackaday. Now it’s grown up and is ready to be manufactured. In the low quality video above [Matthias] shows some of the latest high quality additions to the board. It now has a case, shiny new firmware, production made PCB, and game pad ports. The snega2usb is shipping this December for those who preorder now.

Hack A USB Port Into Your 2010 Prius

[Rosenberger31] did a nice job of adding a USB port to his 2010 Toyota Prius. He removed the access door on the console where the traditional “cigarette lighter” 12 volt port is located. A Dynex 12-volt to USB adapter was piggy-backed onto the power lines and the USB connector was then fit into the blank accessory plate next to it.

There is no data connection here, the port only provides 5v regulated power to devices plugged into it. None the less, it is still a pretty nice looking alternative to having a power adapter hanging out of the dash all the times. If you try this, heed one of the warnings from the comments and make sure you add a switch if you vehicle powers the 12 volt port even when the car is not running.

This makes us wonder: will this void your warranty?

PSP Plus Second Stick, Camera, 32 Gigs

[JoblessPunk] recently finished his what-a-psp-should-be mod. He’s internalized a camera and added a switch in the body to toggle between using the camera or using the USB port. There’s an additional analog stick, and added charging functionality via the USB port. He’s also packed in an additional 32 GB of flash memory. The device is of course running custom firmware which facilitates the ubiquitous flock of emulators and homebrew apps.

We agree that the original PSP is a pretty powerful handheld that never saw a full realization of its potential. With the impending release of the next generation PSP Go we hope the price and availability of the older units leads to more mods of this sort. Check out the video after the break.
