[Alan] posted a video tour of his electronics shop, but you’ll be viewing it through the green screen of an oscilloscope. The image above is a video camera filming a scope screen which displays the image of…. an oscilloscope (insert your own Yo Dawg meme here). But first he shares the technique he uses to [...]

[Alan] was unimpressed by the cheap ticking egg timers that grace many of our kitchens. He decided this was an execllent opportunity to ply his skills with microcontrollers. He built this kitchen timer complete with an enclosure and audible alarm. The device is Arduino based, which makes driving the graphic LCD quite easy thanks the [...]

A month ago, we saw a marvelous demonstration of troll physics from YouTube user [Fredzislaw100]. In his video, we saw a circuit of three switches and three LEDs wired in series and but not acting like the should. A lot of the comments for this post elicited reasonable explanations like modifying the battery or pure camera wizardry via After Effects. Thankfully, [Alan] stepped [...]

How many 555 timers does it take to add up two 10 digit numbers? [Alan's] 555 Adding Machine does it with 102 of them, he designed the machine as an extreme entry to the 555 contest and the original plan was to make it even more complicated. This machine uses the 555′s to implement a [...]

As a project for an embedded systems class, [Alan] recently built himself a sunrise-simulating alarm clock. You are probably familiar with these sorts of timepieces – they gradually light up the room to awaken the sleeping individual rather than jarring them awake with a buzzer or the radio. Since many commercial units with this feature [...]

Sunlit LCD screen [A.J.] did some experiments and managed to replace his LCD backlight using fiber optics and the sun. Game Boy LCD Repair [Alan] found that he could fix dead columns on his Game Boy LCD screen with a little reflow work on the connector. 3DS Design Flaw? Anyone having problems with the way [...]

[Alan] shared an update with us regarding a project he has been working on for some time, radio-controlled LED light strips destined for use by the Travelling Light Circus. If you are not familiar with the project or need a quick refresher, you can read our post about it here. He recently met up with [...]

[Alan] was commissioned to make some wearable, radio-controlled LED strips for the Travelling Light Circus. It has taken some time, but he has recently finished some prototypes, and thought it was a good time to do a writeup on the project. The system is managed by a single controller unit, which communicates with any number [...]

[Alan] acquired a stereo microscope from eBay, and decided to save some more money by designing, machining, and assembling his own arc reactor ring light to go along. After finding an LED driver board sitting around as well as ordering some surface mount LEDs, he set about using a lathe to cut away a block [...]

[Alan Parekh] built this clock to look like a Multimeter using analog multimeters for the three displays. A PIC does the timekeeping and feeds a specific amperage to the three displays which show hours, minutes, and seconds. We’ve seen clocks that use analog meters before. [Alan] took the concept to the next level, replacing the [...]

[Alan] is branching out beyond the Arduino with this clock. He’s still using the same code but built this board around an ATmega328 and the components he needed, saving his Arduino board for further development. The concept uses a character display housed in an old iPod Touch case. The build relies on an infrared sensor [...]

[Alan] noticed that his external hard drive was getting quite hot to the touch after a few hours. He says that it was probably designed to handle the heat sufficiently, he thought it would be fun to beef it up. He’s using a pic 12f675 microcontroller as the brain and an LM35 temperature sensor. The [...]
