Fresh hacks every day
[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these projects in one piece, but not sacrifice his Arduino board, so he etched his own LCD backpack that is Arduino compatible. If you’ve never made it past the Arduino board to build a module that only uses the parts you … Read the rest
[El Artis] just finished building an audio spectrum analyzer that uses a character LCD. The uses an Arduino to drive the display, but unlike other meters that use the microcontroller for analysis, [El Artis] is using a discrete IC for that task.
This project uses the MSGEQ7 graphic equilizer display filter chip to grab frequency data from the … Read the rest
[Sergio] is just getting into hardware hacking. He started by getting an HD44780 compatible LCD screen running with his Arduino. To take the project to the next level, he decided to add a web interface for changing the message displayed on the LCD.
He’s doing things on the cheap (a man after our own hearts), purchasing many of his components … Read the rest
If you don’t have a 9-to-5 type of job you might find yourself constantly resetting your alarm clock as your calendar commitments change. [Lucas] finally got fed up with the nightly ritual and decided to build his own alarm clock which has unique settings for each day of the week (translated).
The display itself is an LM044L 20×4 … Read the rest
This hack is a bit older, but one aspect of the setup makes it worth sharing. Shift registers are a common component to include in a project when you need to increase the number of I/O pins available. We’ve used them to drive LCD screens before, but we never realize you could use a 595 chip to make a 3-wire … Read the rest
Take that cheap fire stick you call a soldering iron and turn it into a real tool. [Giorgos Lazaridis] turned his 30 watt soldering iron into a temperature controlled soldering station by adding a thermistor just above the tip to monitor how hot things are getting. A MAX6675 takes care of the thermocouple and shoots a digital temperature value off … Read the rest
[Manekinen] built a power supply monitor based around an AVR ATtiny13. Voltage and amperage are displayed on a 16×2 LCD character display (we’re not sure what the third number is… samples per second?). This is no small feat considering that the tiny13 is an 8-pin chip. He makes it happen by using the pins for both LCD control and ADC … Read the rest
