Stantum’s High Precision Multitouch

February 19, 2009 by 9 Comments

touch

We love keeping track of new interaction technologies and this new touchscreen by Stantum looks especially promising. Engadget shot a hands-on video with it at the Mobile World Conference. It’s a resistive screen, so it can be used with both fingers and styluses (unlike capacitive screens). It’s sensitive enough that you could use a brush too. The screen supports any number of multitouch points and does pressure sensing based on the size of the detected fingertip. The touch detection is actually more accurate than the screen can display. Stantum is hoping mobile manufactures will pick up their input framework for inclusion in new devices. The resistive touchscreen was built to Stantum’s specifications (it won’t work with current phones), but they say it wouldn’t be hard to go into mass production.

SparkFun Stencil And Solder Paste Class Notes

Hobby electronics manufacturer SparkFun has started offering various classes at their Boulder, CO facility. [Landon] has been attending as many as possible and posted about his experience during their Stencil and Solder Paste class. Solder paste is used when manufacturing boards with a reflow oven. He took quite a few pictures of the process and posted notes and audio. He says it’s definitely something you’d have to learn hands-on, but his numerous photos give you an idea of what’s involved. Below, you can watch a video of the paste clean-up pass and stencil removal.

Brain Controlled Fluid Simulation

Here’s another video demo of [Eric]’s Besmoke interactive fluid simulation that we covered earlier. It was put together for the BIL Conference last weekend. This time around he’s strapped the iPhone to his head (complying with California’s handsfree laws). To make things interesting, he’s also added OCZ’s Neural Impulse Actuator to provide brainwave input.

TinkerKit, Physical Computing Toolkit

tinkerkit

TinkerKit is a collection of 20 different sensors and 10 actuators. It’s meant to make prototyping of physical computing devices much quicker/easier. The devices plug into a Sensor Hub Arduino shield. There is also a similar hub board that can emulate a keyboard; it translates sensor input directly to key strokes. It looks like a very ambitious project and it’s still in development. We love the idea though and think the wide variety of components will foster better final designs. The TinkerKit site covers the current component lineup and there’s a demo video embedded below.

Mobile RFID Scanning

[Chris Paget] is going to be presenting at ShmooCon 2009 in Washington D.C. this week. He gave a preview of his RFID talk to The Register. The video above demos reading and logging unique IDs of random tags and Passport Cards while cruising around San Francisco. He’s using a Symbol XR400 RFID reader and a Motorola AN400 patch antenna mounted inside of his car. This is industrial gear usually used to track the movement of packages or livestock. It’s a generation newer than what Flexilis used to set their distance reading records in 2005.

The unique ID number on Passport Cards doesn’t divulge the owners private details, but it’s still unique to them. It can be used to track the owner and when combined with other details, like their RFID credit card, a profile of that person can be built. This is why the ACLU opposes Passport Cards in their current form. The US does provide a shielding sleeve for the card… of course it’s mailed to you with the card placed outside of the sleeve.

Technology exists to generate a random ID every time an RFID card is being read. The RFIDIOt tools were recently updated for RANDOM_UID support.

The last time we checked in on Pandora it was just being shown in dev unit form. Embedded above is a video of the first case prototype. It doesn’t have any components yet, but it definitely looks like a good formfactor with a lot of potential. The Pandora is a Linux based portable game console with an 800×480 touchscreen.
