LED Driver Board Could Be Your Ticket To FPGA Development

Microcontrollers are a great way to learn about developing for embedded systems. However, once you outgrow their capabilities, FPGAs bring muscle that’s hard for even the fastest-clocked micros to match. If you’re doing anything with high-speed signals, loads of RAM, or something that requires lots of parallel calculation, you can’t …read more

Driving P5 Panels With A Raspberry Pi

Building displays out of LEDs can be fun, but quickly becomes tedious as the pixel count increases. At this point, it’s worthwhile investing in off-the-shelf panels that have everything pre-soldered and ready to go. [Tom Hammond] wanted to run a P5 panel, and put a Raspberry Pi to work to …read more

Simple Trick for LEDs on Solderless Breadboards

Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made indicators with integrated resistors to save space on the breadboard when prototyping — instead of …read more

Teardown The Things You Love

This two-decade old blinkenlights project (YouTube link, and also below the break) would look at home among current $1 soldering kits except for a few key differences. Firstly, it has the teardown artist’s name on the back and comes from an era when DIY circuit boards really meant doing things …read more
