Fresh hacks every day
[Debraj] wrote in about his 2-wire serial backpack he developed for a Graphic LCD screen. It’s build on a hunk of protoboard and uses a pair of 595 shift registers to translate incoming serial data to the parallel interface which is used by the LCD screen. It takes more time to push commands this way, but the interface is … Read the rest
[Tom Fleet] spent the dreary weekend inside learning how to drive this T6963C based graphic LCD controller. Although this is his first time venturing away from HD44780 character displays, the availability of an Arduino library helped him go from being a newbie to coding his own animated graphics.
The hardware setup is straight-forward. The screen has a 20-pin connector … Read the rest
For his first project using the TI Launchpad [VOJT4] built a lap timer and counter for slot cars. For us it’s always hardest to come up with the idea of what to build and we think he found a great one here.
Each time a car passes the finish line of the track it trips a reed switch that … Read the rest
Does the image of the clock above make you shutter with fear because of the math you’d need to use to recreate your own version of the project? We certainly understand that High School geometry is becoming a very distant memory, but it’s really not as hard as you think. [Janw] built this analog clock using a graphic LCD and … Read the rest
With more pixels and more objects to track you’re going to need to get that AVR running pretty fast to get the job done. But [Vladutz2000] figured why stop at 16 MHz when you can overclock an ATmega32 to 27 MHz for a faster gaming experience?
This build may not be as colorful as Super Pixel Bros, but … Read the rest
This is a bench power supply with adjustable voltage and current limiting. [Sylvain's] creation can regulate 0-25 volts while sourcing 0-5 amps. Current limiting is a nice feature as it will allow you to test your prototypes to ensure the power regulator you choose will not be over or underpowered.
This supply is really a two-in-one. The case has … Read the rest
