ATtiny LED driver for an RC car update

joeforker posted an update on his ATtiny LED driver for an RC car we covered previously: This board delivers 100mA through 2 series-wired LEDs like a champ, powered by a 2S LiPo. Night drives are looking bright. The glaringly bright uncomfortable-coming-straight-towards-you high beam look has been achieved. :-) As usual, mistakes were made. The through hole components […]

LED ring based illumination for American optical microscopes

TomKeddie writes: Based on a recommendation in these forums I bought an American Optical 570 stereo microscope on ebay some time back. I added the illumination shown below, I thought it might be useful to others. I cut 3 pieces from a right angle piece of aluminium section, coated them in heatshrink, attached them to […]

App note: Driving LEDs with Xilinx CPLDs

Here’s Xilinx app note on using CPLDs to perform the same functionality as those common LED driver chips. Light-Emitting Diodes (LEDs) are commonplace on the modern day Printed Circuit Board (PCB). Whether they are indicating status, activity or some other function, they need to be driven by a device that can provide sufficient current to […]

Controller board for RGB LED Matrix displays update

EmbeddedCreations posted an update on his controller board for the 16×32 and 32×32 RGB LED Matrix displays: The board looks significantly better with the Teensy soldered directly, instead of with the female headers, but I want to keep the option for people who want to remove their $20 Teensy board to use with another project. […]

Valentine LED chaser

As Valentines day is fast approaching, many are thinking of a wonderful present to their love ones. Tom built this heart-shaped LED chaser and wrote a post on his blog detailing it’s assembly: The object of your desire will not be able to resist a heart-shaped LED chaser, lovingly hand-crafted on perfboard with a CD4017B decade counter […]

RGB LED ring clock

Greeeg over at the 430h forum has been working on a RGB LED ring clock: The clock is comprised of 2 rings of 60 LEDs each. the LEDs are WS2812 parts, which include a built-in driver. The PCB is one of the interesting parts of this clock. I designed the board in altium as a single 6 […]

Controller board for RGB LED Matrix displays

EmbeddedCreations is working on a controller board for the 16×32 and 32×32 RGB LED Matrix displays: I’m working on a controller board for the 16×32 and 32×32 RGB LED Matrix Displays you may have seen at Adafruit and Sparkfun. After seeing Paul’s post on driving WS2811 LED strips with DMA on the Teensy 3.0, I looked into […]

Proverbial LED blink program for chipKit DP32

Ras B blogged about his chipKIT DP 32  he won in our last week chipKIt  giveaway: Ok I just could not resist, and had to post the Proverbial Led blink Program adapted for the DP32, that has 4 LED’s on the board ( Digital Pins 11 to 14). Will scroll them from right to left, speed varying on the […]
