Spikey made his own DIY 32ch FPV 5.8ghz LCD. He writes:
If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on the market now.
Bob hacked a home weather station transmitter and made a home thermometer from it. He writes:
Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I don’t have the receiver station. I decided to bring it back to life.
This is a body thermometer using a thermistor sensor, Arduino and LCD display.
I’ve decided to provide a funny Arduino concept thermometer in case its the middle of the night, pharmacies are not working, you are not feeling well and you want to check your body temperature. If you have Arduino by your side, this is a life saver!
Here is a nice build of a LUX meter using BH1750 sensor and a Nokia 5110 LCD. The meter is controlled by an Arduino Pro Mini and is powered by a Li-Ion battery. The LCD backlight is controlled according to environment light and there is graphing capability of the measured light intensity.
That’s when I realized that I had an unused BH1750 light meter module laying around, which I bought some time ago but never used it. So I grabbed an Arduino, a Nokia 5110 LCD, wired everything up on a breadboard and had a functioning lux meter within a few hours. To make it a bit more fancy, I added some graphing functionality and made the LCD backlight switch on/off depending on the light level.
In this video educ8s.tv is building a Real Time clock and temperature monitor with a big 3.2″ Color TFT display. They are using a DS3231 Real Time clock module to get the time, the date and the temperature. The heart of the project is the powerful Arduino Due board, which can drive the display and update it without any visible flickering at all! Impressive. Let’s start!
A few weeks ago, I tested this 3.2” color TFT display for Arduino with both Arduino Mega and Due. The display works fine and I built a simple project with it. It is a temperature monitor and a real time clock. As you can see at the top, we can see the current date and time, we can see the temperature right now, and at the bottom the Arduino records the minimum and the maximum temperature that it has measured. I also tried to design a basic user interface just with simple shapes. As you can see everything works fine, and it is a very easy and useful project to build. Let’s see how to do it!

This project is an Arduino shield able to measure ECG and respiration. The shield is equipped with a LCD display to show measured signal in real time. It’s based on ADS1292R ECG Front End from TI.
Recently i made shield for arduino which can measure ECG, respiration, eventually after some changes in PCB and code, EEG and EMG. Big advantage of this shield is possibility to make it easily at home. The shield is equipped by display to show you measured signal real-time.
This project is about an accurate mains frequency meter that has a bar-graph displaying the relative deviation from nominal frequency. It can work with 50Hz and 60Hz systems.
An article by Dieter Laues in the February 2012 issue of Elektor inspired me to get my soldering iron out. The article described how by measuring the frequency of the mains electricity supply in any socket, the relative load across the entire electricity network could be determined
Ken Boak discuss how to build a graphic user interface using cheap TFT toughscreen displays. This article is about using their lowcost graphics co-processor IC to provide a neat user interface for any low-end microcontroller.
These days, when you can buy a 7″ tablet for $50, there is all the more reason for makers and hackers to want to become more engaged with up to the minute 7″ touchscreen technology for their latest projects. Fortunately, recent developments in hardware have made this both affordable and easy to do – to the point where no project is too small, not have a neat touchscreen interface – and sound too!
