Check out this visual hardware guide from deviantART member [Sonic840]. It has everything from memory modules, to bus sockets, to power connectors, to an entire array of CPU sockets that have been used over the years. You’re bound to see something in there you didn’t know existed.

Solving the age old problem of… wait, what problem are they solving? These students at UC Berkeley have built a toilet paper dispenser prototype. Not only does it meter out an exact amount for you, it will fold it and cut it as well. They mention this being the perfect accessory for a high tech bathroom, and we can agree. To be serious though, in public places, metering out limited amounts of toilet paper at a time could possibly result in major cost savings. We think the next prototype should have different preference settings such as; wadded, folded, or wrapped around your hand. Anyone else’s mind suddenly filled with unpleasant imagery?

Hardware Keylogger solutions has released the plans and files for their wireless logger. It has a range of about 50 yard between the transmitting dongle and the receiver. It is based around an Atmel AT91SAM7S64 and the PCB is pretty tiny. In case you hadn’t noticed yet, they sell them as well. The cool thing about this is that key data is transmitted in real time, allowing you to see it as it happens instead of having to go retreive the log physically like you used to.

Dating back to September of 2007, this certainly isn’t new news, but its new to us. This is Little dog, the miniature version of the ever so creepy Big Dog. We aren’t sure if the lack of Big dogs signature jogging in place makes this little guy seem more lifelike or less. Little dog was designed to be a research platform into study automated navigation of natural terrain. We wouldn’t mind having one of these around the office, though we would have to add some kind of a head or face to give it some character.

Here is a nice video to wind down the day. It’s [neorazz]’s micRo playing the theme from Tetris. The micRo is a simple CNC kit sold by the team at Lumenlabs. For more servo music, peruse our CNC category.

Here’s another adafruit product launched today: a prototyping shield that compensates for the Arduino’s stupid oddly spaced headers.
Related: The Seeeduino has an alternate row of headers with protoboard friendly spacing.
adafruit industries’ latest product is an adjustable breadboard power supply kit. We’ve seen breadboard supplies before, but like most of adafruit’s kits, this is the best design you’re going to encounter. It uses an MIC2941 voltage regulator instead of the more commonplace LM317. It has a very low dropout which means your output voltage can be much closer to the input voltage. Their example is using 3AAA or a Li-Ion battery for an output of 3.3V. Input can be through a barrel jack or terminal blocks. There is a selection switch for 3.3, 5, and adjustable voltage. Using the adjustment pot you can select an output voltage anywhere from 1.3V to within .5V of the 20V maximum input. The adjusted output voltage will remain the same even if you increase the input voltage. Like all of their kits, you can find schematics, assembly and usage instructions, on their project site.
