FM Bug Using Salvaged SMD Parts

October 22, 2010 by Mike Szczys 20 Comments

If you’re a soldering ninja this FM transmitter bug is for you. It’s quite similar to the one we looked at yesterday, but this uses 100% salvaged parts. Two phones donated components; a Nokia 3210 for its voltage-controlled oscillator and a Nokia 1611 for the rest of the parts. The bad news is that mobile technology like cellphones use some of the smallest surface mount packages known to man. That’s where the soldering skill come into play. The good news is that if you’ve been scavenging for discarded phones in order to reuse their LCD screens you already have these parts on hand.

Tiny FM Transmitter Bugs Rooms

October 21, 2010 by Mike Szczys 30 Comments

Lucid Science delves into spy-tech once again with this tiny FM transmitter. Their post demonstrates a bit larger version than seen above, using a 9-volt battery and protoboard sized to match which makes for easier soldering. The design uses a microphone, two transistors, enameled wire for the coil, as well as various resistors, capacitors, and a potentiometer. What you end up with is an amazingly clear audio signal that can be picked up with a normal FM radio.

This would make a great project to do with the kids. You can talk about circuit design, practice soldering, and when finished they’ve got an almost miraculous toy to play with. Just be careful what you say around the house, the room might be bugged!

DelFly2 And DelFly Micro

The video you see above is the on board footage of the DelFly2 autonomous ornithopoter robot. Weighing 16 grams, it carries a small camera and can provide a live feed. If you’re amazed at the tiny size and weight of the DelFly2, check out the DelFly micro, video after the break, that weighs 3 grams. Remember when we thought 17 grams was small for an ornithopter?

All processing for the DelFly2 is done at a base station and transmitted to the flying bot to keep the weight down. The team also had to create their own brushless motor that runs at 60% efficiency and weighs only 1.6 grams. The 130mAh battery can sustain 15 minutes of horizontal flight or 8 minutes of hovering.

It seems like every piece of hardware has to earn its respect by going through some standard paces. One of which is having Quake ported to it. Much like an angel earning their wings, Bug Labs, with the help of community [CMW], has ported Quake to the BUG. Right now, the only add on needed is the BugView module. Controls are done through the base unit.

Bug Labs Introduces New BUGmodules

Bug Labs, the company that makes modular electronics that allow you to build your own tech doohickeys quickly and easily, has announced five new modules: BUGprojector, a mini DLP projector developed in conjunction with Texas Instruments, which sounds very much like the tiny DLP projector we posted about last week; BUGsound, an audio processing module with four stereo input/output jacks, a microphone, a speaker, and builtin hardware codecs; BUGbee (802.15.4) and BUGwifi (802.11 and Bluetooth 2.0+EDR), which will let you connect wirelessly with your PAN and WLAN, respectively; and BUG3g GSM, for connecting to (you guessed it) 3G GSM networks. In conjunction with Bug Labs’ existing series of modules, especially the highly versatile BUGvonHippel universal module, you’ll be able to create some pretty kickass gadgets. No word yet on pricing, although Bug Labs expects to ship by the end of Q1 2009.

Bug Labs Releases BUGvonHippel Universal Module

Bug Labs makes hardware modules that can be combined to create your own custom gadgets. They’ve just released what we consider the most useful module: BUGvonHippel. Unlike the previous single purpose modules, the BUGvoHippel is a universal interface. The bus features USB, power/ground, DAC/ADC, I2C, GPIO, SPI, serial, and more. BUG applications are written in Java using a custom IDE.

The $79 module is named after MIT professor Eric von Hippel, who wrote Democratizing Innovation. You can find an interview with him below.

Apple Finally Fixes DNS Bug

September 15, 2008 by Eliot 4 Comments

With today’s release of Security Update 2008-006 Apple has finally addressed this summer’s DNS bug. In their previous update they fixed BIND, but that only affects people running servers. Now, they’ve updated mDNSResponder. Clients are no longer susceptible to DNS cache poisoning attacks thanks to the inclusion of source port randomization.

The Security Update addresses some other interesting bugs. Time Machine was saving sensitive logs without using the proper permissions, so any user could view them.
