[Bogdan] received this set of Serioux Panda speakers as a gift. I turns out that they sound very good and he decided to make them more useful to him by converting them to work as Bluetooth speakers. To begin with he bought the cheapest A2DP device he could find. This is the protocol that identifies [...]

After adding a few LED light strips above his desk, [Bogdan] was impressed with the results. They’re bright, look awesome, and exude a hacker aesthetic. Wanting to expand his LED strip installation, [Bogdan] decided to see if these inexpensive LED strips were actually less expensive in the long run than regular incandescent bulbs. The results [...]

If you’re like a lot of people, most of the time your computer speakers are on without actually playing any music. This wastes a bit of power, and [Bogdan] thought he could create a circuit to cut down on that wasted electricity. The result is a very tiny auto-on circuit able fit inside a pair [...]

[Bogdan] sent in a great build of a delta robot he originally posted on the Arduino forum, but he didn’t receive much feedback there. We think a build like this deserves a lot more credit. After working for 7 months on his robot, [Bogdan] has a pretty stable (and very classy) platform made out of [...]

[Bogdan's] latest project is a box that displays web hits for a chosen site. He calls it the Ego Box because depending on how traffic goes it either bloats or crushes your ego. This provides similar functionality as our Troll Sniffing Rat but the biggest difference is that this is a stand-alone Ethernet device. That’s [...]

These are both interesting, unrelated, and can’t quite stand on their own so we threw them into one post. On the left you see the product of using toner transfer on ABS plastic. [Bogdan] tried this out as a way to make front panels for his enclosures. It really shouldn’t work very well because ABS [...]

There are two methods of using etchant resist when making circuit boards. We use the toner transfer method that requires ironing on laser toner to the copper, but you can also use chemical resist that reacts to ultraviolet light. [Bogdan] decided to start doing more of the latter so he built a UV exposure box [...]

[Bogdan] has some trouble getting up in the morning. A blaring alarm will do the trick but that’s no way to start the day. To get him through the dark winter months he wanted to try a sunrise simulator. He patched into the alarm signal of his bedside clock, intercepting the command from the clock’s [...]

[Bogdan] set out to build the all-too-familiar binary clock. But, he didn’t want to be ordinary, and set the goal of making the clock as hard to read as possible. What he ended up with is a clock that is almost impossible to read correctly. He’s using colors to tell the time. We immediately thought [...]
