Fresh hacks every day
Hot glue guns can be very handy tools for bonding all sorts of surfaces, while getting you accustomed to plastic burns. The one thing they lack though is color, and while yes, you can on occasion find colored glue sticks, there is usually only a limited selection and they cost way more than the normal amber or clear sticks. [Ken] solves the blandness problem of hot glue sticks in his kitchen, as … [Read more...]
[Brendan Vercoelen] is a university student in New Zealand studying engineering. He says his recent gigantic LED cube build, "isn't very serious" compared to other student projects, but that doesn't mean it's not impressive. The original plan for the build was a 16x16x16 tri-color LED cube. After realizing how much soldering that really was, [Brendan] scaled back his design a little to a 16x16x8 … [Read more...]
[Robovergne] prides himself on the beautiful reef aquarium that he has set up in his home. These sorts of water displays require constant maintenance due to the mineral requirements of living coral. Rather than add mineral solutions manually, he decided to build a nano-doser using espresso machine pumps (Google Translation). These vibration pumps run on mains voltage, so he had several options … [Read more...]

Using ping-pong balls, some scrap plastic and 6 servo motors [Chris] has created these animatronic eyes along with some nifty animated eyebrows. To get motion emulating realism [Chris] created a 2 axis gimbal using plastic rings and some nuts and bolts. The eyes (ping-pong balls) are held in the gimbal and actuated using two … [Read more...]
[Dino Segovis] wrote in to tell us about his "hack", making an AB Audio Amplifier. The advantage of this particular amp is that the transistors never turn off, which would cause distortion. A full schematic is given in the article as well as a parts list. A complete "bill of materials" makes any circuit building project easier, especially for the beginner. Although this is by no means a new … [Read more...]
Normally when we see an R/C transmitter used in a build we're prepared for robots, quadcopters, or UAVs. [Alex] found a new use for his Futaba radio - hooking it up to his Super Nintendo. We've seen a lot of builds using game controllers as interfaces to other hardware. The N64 media remote comes to mind, as does the NES iPod dock. Outside of a few builds to automatically win in-game currency … [Read more...]
