Stepping Through Code on a Pace 4000 Set Top Box

[Lee] wrote in to tell us about a Set Top Box he hacked. Before the cable industry lawyers get out their flaming swords¦ he™s not stealing cable, or really doing much of anything. This is a hack just for the adventure and thrill of making someone else™s hardware design do your bidding without any kind of instructions.

He posted about the adventure in two parts. The first is finding the JTAG header and identifying the pins. Arduino to the rescue! No really, and this is the type of Arduino use we love. Using a package called JTAGenum the board becomes ¦ Read the rest



Auto-Balancing Gimbal Keeps your Coffee from Spilling

[Joe] works in one of those fancy offices that has some¦ unique furniture. Including a swinging boardroom table. See where we™re going with this? [Joe] made his own coffee cup gimbal.

The gimbal itself is made out of solid steel, welded together for maximum durability. He first built it out of plastic to test the concept, but then quickly moved to the all-metal solution. It™s a 2-axis gimbal featuring very powerful brushless DC motors, capable of balancing even a light-weight DSLR ” however we think balancing a coffee cup is much more entertaining. It does this with ease, even when ¦ Read the rest



Vector Laser Projector is a Lesson in Design Processes

Now Uni™s aren™t in the habit of just forking over funding for no reason, and we thing that™s why the two did such a great job of documenting their work. We™re used to seeing blogs devoted to one project, but this one has a vast portfolio of every piece of work that went into the build¦ Read the rest

Experience the œFarmer™s Market of Vintage Electronics

Normally when you think of a Farmer™s Market, fresh produce grown nearby comes to mind. This experience was similar in that much of the produce was conceived locally, but the goal is to be anything but fresh. I had the opportunity last weekend to attend the final Electronics Flea Market of 2014. I can™t speak for everyone, but there is an obvious affinity for vintage electronics equipment in just about any condition. The people you run into are as interesting as the equipment being swapped, and the social outing tends to continue even after the swap meet closes.
