Hack a Day
Here’s an oldie but a goodie: [Eiki], [Mark], and [Sheraz] built a pipe crawling robot for their senior engineering project at Florida Atlantic University way back in 2004. Despite being a rather old build, its aged well and still demonstrates the clever ways the guys overcame some engineering obstacles. The original plan for the pipe [...]

Hack a Day
[Mark] wrote in, eager to show off this new tool he’s created to view your gerber files in 3d. He also wrote an instructible to go along with it, to help you figure out how to use the tool. Being an in-browser tool also means you can shoot it to your friends for a quick [...]

Hack a Day
[Mark] from SpikenzieLabs was wrapping up a project using an Arduino the other day and found himself in need of a few more I/O pins. He could have added extra circuitry to the project, but he decided to see if he could gain a few pins by removing a few components instead. He put together [...]

Hack a Day
Over the last two years, [Mark] at the Harford (and Baltimore) Hackerspace has been building 401k, a humanoid robot that will soon be able to walk on two legs, detect objects, and fight along with its comrades in the robot insurrection that leads to the extinction of man. To get an idea of how complicated a [...]

Hack a Day
Last year, [Mark Simonelli’s] wife asked him if he could design something that would allow her to remotely check if their garage door had been left open. [Mark] jumped at the chance to tinker with electronics and designed a system around an old TrendNet IP camera. When remotely connected to the camera using IP Cam [...]

Hack a Day
[Mark VandeWettering] was experimenting with a simple transmitting circuit and an Arduino. The circuit in the project was designed by [Steve Weber] to broadcast temperature and telemetry data using Morse Code. But [Mark] wanted to step beyond that protocol and set out to write a sketch that broadcasts using the Hellschreiber protocol. This protocol transmits [...]

Hack a Day
When [Mark] sent in the tip about this crawling zombie prop he said that it didn’t sound scary but warned us that it is terrifying when you see it. He’s absolutely right, the video after the break shows some remarkably undead movement from the thing. This crawler is actually radio controlled. Details are brief, but there’s plenty [...]

Hack a Day
[Mark] had seen a few examples of algorithmic music generation that takes some simple code and produces complex-sounding results. Apparently it’s possible to pipe the output of code like this directly to audio devices on a Linux box, but [Mark] decided to go a different direction. His project lets you play simple algorithms as audio using [...]

Hack a Day
If you’re looking for a simple Ardunio project, why not replicate the first personal computer? After discovering the Arduino, [Mark] realized recreating really old computers would be a fun project. An Altair 8800 was on the table, but the sheer number of blinkenlights, switches and the Intel 8080 CPU made that a fairly difficult project. [...]

Hack a Day
[Mark] wrote in to share a little creation that he is calling the first solar-powered 3D printer in existence. While we can’t say that we totally agree with him on that title, we will give him the benefit of the doubt that this is the first solar-powered RepRap we have seen thus far. You might [...]

Hack a Day
[Mark] and his friends love fireworks, but got tired of the traditional ground-launched mortar rounds, so they decided to spice things up a bit. A while back he purchased an Army-issue bazooka at a gun show but didn’t use it for much, so it sat unused for about 10 years. He dug it out of [...]

Hack a Day
[Mark] was playing around with a small GPS sensor when a light bulb lit over his head. He imagined it would be pretty cool to replicate one of Google’s Street View cars at a fraction of the scale using Lego NXT parts. He figured it would be easy enough to rig a few cameras to [...]

Hack a Day
[Mark Fickett] finished his own interesting take on a bicycle computer. These wristwatch-sized devices normally mount to the handlebars and give feedback for current speed, trip distance, and many have options like cadence and heart rate. [Mark's] has fewer features but it’s clean, simple, and does more than you’d think. He used some denim to [...]

I will be moderating a session at ITExpo West on Monday 4th October at 2:15 pm: “The State of VoIP Peering,” will be held in room 304C.
Here’s the session description:
VoIP is a fact – it is here, and it is here to stay. That fact is undeniable. To date, the cost savings associated with VoIP have largely been enough to drive adoption. However, the true benefits of VoIP will only be realized through the continued growth of peering, which will keep calls on IP backbones rather than moving them onto the PSTN. Not only will increased peering continue to reduce costs, it will increase voice call quality – HD voice, for instance, can only be delivered on all-IP calls.
Of course, while there are benefits to peering, traditional carriers have traditionally not taken kindly to losing their PSTN traffic, for which they are able to bill by the minute. But, as the adoption of IP communications continues to increase – and of course the debate continues over when we will witness the true obsolescence of the PSTN – carriers will have little choice but to engage in peering relationships.
This session will offer an market update on the status of VoIP peering and its growth, as well as trends and technologies that will drive its growth going forward, including wideband audio and video calling.
The panelists are:
This is shaping up to be a fascinating session. Rico can tell us about the hardware technologies that are enabling IP end-to-end for phone calls, and Mark and Grant will give us a real-world assessment of the state of deployment, the motivations of the early adopters, and the likely fate of the PSTN.

Hack a Day
Here is the 32nd amateur fusion reactor built in a basement. [Mark Suppes] is right behind [Will Jack], the (then) 17 year old [Thiago Olson], and [Mileiux] in engineering a homemade nuclear reactor. By taking two light elements and colliding them under extreme speed and pressure, a heavier element and energy are produced. [Mark's] goal [...]

Hack a Day
If you’re curious about tube amps but don’t have a firm enough knowledge base to dive right in you might want to try a kit. [Mark Houston] reviewed one such kit and we enjoyed reading about his experiences. It comes with everything you need save soldering tools, an enclosure, and the final connectors ([Mark] used [...]
