Automated pumpkin patch to scare trick-or-treaters!

Using eight jack-o’-lanterns and an Arduino Mega, “CrankyCoder” built his own automated pumpkin patch.

CrankyCoder’s favorite holiday, as well as his family’s, is Halloween. After creating a skull that follows people around a few years ago, he decided to take things up a notch with his “Creepy Pumpkin Patch.” His patch includes eight pumpkins on the edges of a path with homemade pressure switches in between. As trick-or-treaters walk by, the patch is activated, making the pumpkins spin creepily.

Cleverly, CrankyCoder employs two pie pans with marbles in between for each rotating pumpkin, creating ball bearings to support the weight. Also, instead of a candle or other complicated electronics, he’s using flickering LEDs from the dollar store to produce a creepy lighting effect.

With Halloween just days away, be sure to check out the project’s video seen here or its GitHub page to get started on your own Creepy Pumpkin Patch.

81 7-segment displays combine to form mega Sudoku game

Using a rather large custom PCB, Hari Wiguna made a Sudoku board using discreet LED displays and a physical keypad.

Most people, buy a book and play Sudoku with a pencil or perhaps just get an app. Those that are really dedicated buy a standalone game, but this wasn’t good enough for Wiguna, who made his own electronic board not out of a normal LCD screen, but from 27 three-character LED modules to display the game on a glowing grid. Input is done via a keypad, which uses the grid layout to allow for two-button selection of any square.

Though extremely impressive, it doesn’t yet have a puzzle generator. Wiguna would welcome any contributions for this code-wise!

You can find out more about this project on his pageon GitHub, as well as in his detailed YouTube videos below.

Dad builds a ‘Princess Cumulus’ costume for his daughter

Maker dad Royce Husain and his daughter Zoey have made it an annual Halloween tradition to build fun and exciting new costumes. Following in the footsteps of last year’s El Niño project and the incredibly popular Minnie Mouse stick figure from 2014, the duo is back with another elaborate getup: a Princess Cumulus thunderstorm that is admittedly “a bit impractical for actual trick-or-treating.” (But cool nevertheless!)

The costume itself consists of a cotton-covered inflatable suit along with LED strips connected to an Arduino programmed to produce a flashing lightning effect.

Be sure to check it out below!


Pomoduino Timer

Pomodoro Technique is a popular time management method. It is based on the idea that frequent breaks can improves mental agility. And by breaking down the work into 30 intervals and separated by short breaks, one can largely improve his productivity.Although I found it less helpful when using a pomo...
