Instead of taking pictures of circuit boards, why not scan them. The results are very good. “An image scanner can make great pictures of circuit boards. Not only are the pictures clear, they are very high resolution and have nearly perfect scaling. Perfect scaling means that you can actual make measurements from the image. Try that with a digital camera! I picked up the pictured Artec scanner for about $20
Philo has developed a new NTX LEGO sensor that is worth taking a look at. “I built this proof of concept of a light barrier using NXT light sensor and an optic fiber. Any small object passing between the end of the fiber and light sensor phototransistor can be easily detected, even if they have different color or reflectivity. The fiber I used comes from the RIS 2.0 kit, but
Nuxie1 did a great job on this PIC based USB project board. I am very impressed by the Eagle 3D plugin that was used to create the image above. “This design uses the Microchip PIC 18F2450 or 18F2550 USB enabled microcontroller. The total parts cost is around $15 including the microcontroller for a single board. The board features a USB port that can be used with a bootloader for easy
Check out this disco ball, it is powered by a CD player motor. Similar to this one, but spins by itself. “Here is my version of the LED Disco Ball. Its Completely portable can either be hung or screwed to the roof. It runs on 3AA batteries and has a group of gears from a CD player laser. Parts List: -3AAs -Metal Fujicolor Negative Film Control Strips Container -2 UV
You probably remember the Shock Clock from a while ago. Well this Zedomax RGB LED Alarm Clock is the oposite of that concept, I think it would be soothing to wake up to this clock… “Okay, we have seen some really cool Light Orbs while trying to make this Music Syncing Light Orb Alarm Clock. We started with Tod’s creation and soon realize that 1 LED will not be
You might remember the article of the in progress 6 Axis PC Controller, well it is now complete. This thing is very impressive, doesn’t look like the standard weekend DIY because of the complexity. “My microcontroller doesn’t have built-in I2C or SPI, so I needed to implement one of my own. I also didn’t have interrupt pins available, meaning my solution needed to be based on polling. When all
You can spend $50 on a store bought golf training aid, but Zedomax shows you how to make your own for about $5. There is also a video of the thing in action on his site. “It’s getting near Christmas time and I needed to prepare some Christmas gifts for my parents. Since my Dad does not get much time on the golf course these days, I figured I
