LM1117

The LM1117 is a low dropout voltage regulator with a dropout of 1.2 V at 800 mA of load current. The LM1117 is available in an adjustable version, which can set the output voltage from 1.25 to 13.8 V with only two external resistors. In addition, it is available in five fixed voltages, 1.8 V, 2.5 V, 3.3 V, and 5 V. The LM1117 offers current limiting and thermal shutdown. Its circuit includes a Zener trimmed bandgap reference to assure output voltage accuracy to within ±1%. A minimum of 10-µF tantalum capacitor is required at the output to improve the transient response and stability.

Matrix Game Console

Folding Clock

“An interesting 3D printed clock that folds out flat or back on top of itself. Recently I build a Cube clock that showed the time in the same orientation no matter what orientation the clock itself was in. This was …

The Ultimate Logic Probe

“A small logic probe for CMOS and TTL circuits. Measures 5 states, detects pulses and can play different tones for the different states. Looking back through some of the stuff I have built over the years I came across a …

Inductance Meter

“An Arduino based meter to measure inductors. This project is a remake of an inductance meter by sagar saini. My variant has the following changes/additions: - ATtiny1614 CPU replaces Arduino UNO - LMV311 comparator replaces LM339 comparator - Battery powered with deep …

Tiny Space Invaders Game

“A battery or external powered LCD 1602 game console with built in Space Invaders and Space Impact games. Recently I did a project called Tiny Space Impact Game. After finishing it, I realized that the console itself was very generic …

Tiny Space Impact Game

“A rebuild of the Space Impact Rocket Game by Mohd Sohail. New hardware, 3D printed case, improved software, battery or externally powered. This project is a rebuild of Space Impact LCD game by mohammadsohail0008. I really liked the concept. This …

Electronic Depth Gauge for Dremel Drill Press

“A clip-on electronic depth gauge for a Dremel Drill Press. No wires or screws required. Sometimes during a build, you may need to drill holes of a fixed depth. I have a Dremel Drill Press and while it is a …

UV Exposure Box

“A UV Exposure Box to expose photoresist or solder masks for single and double boards. Most of the projects that I build have a custom printed circuit board. With a preference to making my own PCBs rather than use proto-boards …
