Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output

If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in the megohm range, and can fall to hundreds of ohms or even less when exposed to sufficient light. You first instinct when proto ...

Taking Advantage of Embedded FPGA (eFPGA)

Whether you are designing an SoC, MCU or other chip, the one common heartache is “freezing RTL.” Up until that point, it’s no problem making a change or update, but once it’s frozen, the chip design is “locked in.” A change after that point could require a new spin that is not only costly, but can also significantly delay the chip development schedule. Now imagine what it would be like to have no deadline t ...

RaptorLoc Pro – A versatile modular third hand system

The Story Dear fellow Kickstarter Patrons, at various points in my life, I’ve built RC cars, messed with Arduino projects, built custom computers, assembled models, added LEDs to my snowboard and so on. A common thread in these projects was the need to hold pieces in place while I soldered, glued or painted my parts. The usual solution is some type of third hand tool…and there are some good ones out there b ...

BML GPIO-14 USB Board for PCs

Ever miss the simple days of using a PC’s LPT1 parallel port to bit-bang GPIO over 8 output pins and 4 input pins of the DB-25 connector? I sure do. My first design project as a BSEE graduate in 1993 was to design a LPT1 controlled test fixture for the Motorola MDT-9100-T data terminal (shown below). Those were the days. By multiplexing 12 parallel port pins into 74HC dip CMOS latches and transceivers my te ...
