The planterbot is a plant monitoring robot. It uses capacitance for sensing moisture from the plant instead of using the usual soil probe, this means that wires don’t go into the plant. It also detects temperature and light using thermistors and Cds photocells and displays the temperature and light graphically on the front facing LCD.

TinyScreen is a tiny customizable display. Play games, get notifications from your phone and display useful information.
TinyScreen is the new way to visualize your environment. With a beautiful color OLED display, TinyScreen is designed to be used to display information from the TinyDuino platform, which stack together like little electronic Lego’s.
With TinyScreen there are several default apps that will work right out of the box – like a Smart Watch app, a Video player app and a video game app. You can use these default apps with NO PROGRAMMING AT ALL!

I built a custom OBD II gauge in the clock of my Subaru BRZ (GT86, FRS) and a lot of people wanted me to build them one. Here is how you can build one of your own. My wife is about to give birth to our second son and all the code is open source, so I have nothing to lose by posting this.

LG Display has an excellent article on how they build TFT LCD displays:
Ever wondered how the TV and monitor displays you use every day work? The TFT-LCD manufacturing process consists of a set of processes for producing TFT, color filtering, cell, module and others. LG Display Newsroom gives a detailed, but easy to follow explanation of the entire steps below.
Let’s take a closer look at the production process for a TFT board, the bottom-most layer of an LCD panel. The image above depicts a TFT board, which consists of rows of small rectangular sections that together resembles a chessboard. Each rectangular section is a pixel, and each pixel contains a transistor that controls its function. The TFT process is the process that builds these transistors on top of a glass substrate.

With the Bolymin BE635 graphic embedded module it´s possible to focus only on software development – hardware is done.
A possibility to interactively adjust various parameters and at the same time to see a “result” of our settings (for example a status of a given device) considerably increases safety and reliability in various industry sectors. That´s probably one of reasons why a graphic output becomes a standard even in devices, where they were recently used very rarely so far.
From the development point of view, one of the key deciding factors is a platform, on which a given system is built (processor, OS).
PIC32 family certainly belongs to popular microcontrollers (32 bit RISC CPU), that´s why the new graphic embedded module Bolymin BE635 addresses all, who know PIC32, or they want to become familiar with it. For everyone, who´ve ever worked with PIC32 family, a development of application will be much easier with BE635, as practically all necessary hardware is on one board and at the same time we get a support in a form of various drivers for communication as well as graphic output. For programming purposes a new Microchip PICkit3 is suitable and SW development can be done in the known environment Microchip MPLAB IDE. BE635 is designed as a universal module, where only a designer decides, how much computing power of a processor will use on which activity (displaying, data processing, external HW control, communication, …), that´s why possibilities of its usage are really very wide.
Compact module (93x67x15mm) with a 3,5“ TFT LCD display (320x240px) is equipped sufficiently, to become attractive. For example:
- built-in 512kB ISP flash/ 64 kB SRAM/ 16 kB EEPROM
- support of microSD
- 1x RS232, 1x SPI, 1x I2C
- selectable 1x RS232/422/485/USB (depending on a version)
- 1x 10bit ADC, 12x GPIO
- libraries for successful programming, drivers for interfaces and a touch panel
BE635 is available in 4 versions, differing by an additional RS232/485/422/USB port. Single supply 5V and easy mechanical assembly by means of a metal frame with mounting holes also belong to pluses of a new BE635. Soon, there will be available also other similar modules with the same functionality but with bigger displays, for example BE657 with a 5,7“ (640x480px) display, thus an application for BE635 will be usable for the BE657 alike.

Very small power supply unit in the size of a cigarette box. The input voltage is 24V. Its supplied by a external switch mode AC/DC PSU. The output voltage range is 0V to 24V at 0A to 3A. A switch mode preregulator reduces the power loss. This allows a very compact design. Voltage and current are displayed on a RGB OLED display

Peter Jakab has written a new article on how to adapt character LCD modules for 3 volt operation.
Generic character LCD modules contain an industry standard HD44780 compatible controller, which can operate down at 3 volts. But the modules are usually specified to work only at 5 volts, unless you choose a specific one designed for 3V operation. It is possible and simple to adapt the 5V modules to work on 3 volts.

BMO from Comedy Central’s Adventure Time is adorable, if only someone would make one that can walk! Atleast we can make one with a personality. Here is a build using easy to get parts including Arduino Pro Mini, Nokia 3310 LCD screen, audio playback, accelerometers, and distance sensors.
The parts added up to around $70.00

Infrared remote control for home appliances is a popular project among hobbyists and students. Smart Outlet is a similar project that provides an infrared controlled AC outlet to connect any electric appliance and has an integrated timer in it. The appliance can be turned on and off from several feet away using an IR remote. The device is Arduino-controlled and has a LCD display to provide a menu based interface to the user for its operation and settings.
