Wake up calls for phones?

Wake up calls for phones?

CellphoneSean was looking for a service that would automatically call his phone with a text to speech message at a specified time “I would like to be able to program my computer to call my cell phone or a regular phone with text to voice messages–eg reminders, important appointments or wake up calls and for pranksters…The catch is that the other person should not require the same software to receive the call. Anybody know of any software that does this univocally?” I found a web service that does this (some free and some fee) here. I usually use my built in alarm clock on my phone, but it doesn’t of course talk to me or call anyone else.

Functional prototypes in 30 minutes or less…

ProtoI asked Scott and Bjoern to write up what they’re up to when I saw the challenge of making a functional music player in 30 minutes, they write “d.tools is a hardware and software system that enables designers to rapidly prototype the bits (the form) and the atoms (the interaction model) of physical user interfaces in concert. d.tools was built to support design thinking rather than implementation tinkering. With d.tools, designers place physical controllers (e.g., buttons, sliders), sensors (e.g., accelerometers), and output devices (e.g., LEDs, LCD screens) directly onto form prototypes, and author their behavior visually in our software workbench.” More info and downloads here.

Quanta to build the $100 dollar laptop…

Tn-Laptop-CrankI think Quanta makes Apple’s Powerbook too, I wonder if they made the eMate“The One Laptop per Child (OLPC) organization, which hopes to bring a $100 laptop championed by MIT’s Nicholas Negroponte, has selected Quanta to serve as its original design manufacturer, or ODM. ODMs typically manufacture products, but also participate substantially in the final design. Although not many U.S. consumers know the name, many own Quanta’s products. The company produces systems for Hewlett-Packard, Dell and others. It is engaged in a long-running rivalry with Compal, also based out of Taiwan.” Link.

DIY Hardware shredder…?

DIY Hardware shredder…?

ShredderMAKE reader Matthew writes “I woud like to suggest a make project to design and build a hard drive/electronics shredder, not one to shred software but something to shred actual metal hard drives, they have commercial versions. The end product can be recylced.” Awhile back there was a round up on G4’s Destroy All Data and I’ve also seen this company and their crazy couch shredding, computer devouring videos, as far as DIY solutions – how about a hard drive clock? Post suggestions in the comments!

HOW TO – Emulate the Telezapper on your voice mail

HOW TO – Emulate the Telezapper on your voice mail

ZapperHere’s how to emulate the telezapper by using SIT tones on your answering machine or voice mail messages…“Predictive Dialers are used by telemarketing firms to gain more ‘dialing efficiency’. About 75% of junk calls are made with a predictive dialer (PD). One thing a PD does, is monitor what happens when the phone is answered. The Telezapper can emit a ‘disconnect’ tone when your phone line goes off-hook. The tone it transmits is either a single ‘ultra-modulated’ tone or an actual set of 3 ‘Special Information Tones’ (S.I.T.) common to the telecommunications industry: depending on the setting you seletct. It works… now… in some situations. You can get a set of all three Special Information Tones from Private Citizen. Just record the tones at the beginning of your answering machine message and put your greeting right after it.” Link.

Adding internal Bluetooth on a Dell laptop…

Adding internal Bluetooth on a Dell laptop…

72847299 Ea0B9A0215Nice mod, adding Bluetooth to laptop with an extra USB port…TomTheGeek writes “This weekend I added internal bluetooth to my Dell CPx laptop. These laptops have a two port USB hub in them but only one is available on the outside. The other one is only used if you have a docking station. Since I don’t have a docking station I found the traces for the unused USB port and placed my USB bluetooth module internally. These are the connections I had to add to the main board in order to use the USB port…” Link.
