On February 14, it was another year of Western Valentine's Day. As an electronic engineer, this year is preparing to give the special TA in your heart, send a TA whose heart-free festive gift? If you have no shortprints now, let's take a look at some good ideas that can stimulate your creative design ...
Just do a good job of cashing, Western Valentine's Day will come to report. For many people, this means that it takes a lot of money to buy a traditional gift such as Valentine's Day card, chocolate or flowers, or eat dinner with the lover. Although it is a well-selected gift or a creative atmosphere, it is more happy, after all, it is specially made for someone, it is not the goods you can see on the store shelf. !
Before Valentine's Day, I hope that the electronic engineers have time to create a special design for the special one (or her) in the heart. But if you have nothing to do now, the following is some good ideas that may inspire creative design, you should make it easy before Valentine's Day, and of course you can successfully win the touch and satisfied smile on your lover.
1: Openelectronics Heartthrob Heart LED

OpenElectronics Designed HeartThrob gadgets may seem like a normal heart-shaped LED, but it is not as simple as the surface. HeartThrob not only lits different LED patterns while shaking, but also can play some complex light games. Inside the PLA plastic housing manufactured in 3D, it is a heart-shaped CDC composed of 32 LEDs, and is driven by Atmel Attiny85 Microcontroller (MCU).
In order to allow the chip to control the I / O required for so many LED lights, OpeneleCtronics uses TI 16 channel LED drive TLC59401. In addition, the HeartThrob heart-shaped LED is powered by a chargeable LIPO 3.7V 500mAh battery, which can last for 90 minutes after full charge.
2: Vegard Paulsen's Valentineduino

ValentinedUino, Valentineduino, is a smart device that can calculate how many days you have spent with your lover. This simple design uses the SparkFun 4-digit seven-segment display (SSD) and is installed in a covered small wooden box. In addition, Arduino Pro Mini connects all power supplies using the Veroboard board. The ValentinedUino record time is originally used to use a pair of RF modules, capture data from the Internet, and later VEGARD replaces in real time.
3: Rusivan's DIY LED Heart

Another great Valentine's Day gift design from an Instructable, a user [Rusvian] and his DIY work. This LED Heart is designed with a Customari PCB and is equipped with an ATMEGA8 MCU for driving 22 LEDs on an etching PCB, and a pair of CR2032, capacitors, and an LM7850 voltage regulator powered by a circuit board. The designer finally placed the PCB in a photo frame from multiple different image collages.
4: Kodylab's Arduino Magic Flowers

Flowers are of course the best gifts, but Arduino Magic Flowers does not want to simply be a plant, which is included with embedded RGB LEDs that can be converted into a variety of different colors. Kodylab's simple design uses a built-in LPD8806 RGB LED (driven by Arduino) and is mixed with Sharp GP2Y0A21YK infrared (IR) near-sensor, when detecting any action near its location, change the color of the LED, Thereby showing excellent display effects.
5: 3D Printed Chocolate Molds

If you have a 3D printer, you can consider the tool with Adafruit tool to create a mold that can be used to make a chocolate, and then use chocolate to make a wide variety of different shapes or geometric patterns. Autodesk's 123D Design application helps you create the desired model, or import SVG vector graphics. After completing these 3D print models, it is used to cast silicone molds. Finally, just let chocolate melt, and insert a small wooden stick with a lollipop, then let them cool.
6: Interactive Valentines Box

Lying in Valentine's Day with decorated shoe box is still a tradition of schools and offices. Sparkfun's Ministry of Victory Feldi designed Interactive Valentines box allows the functionality of the decorative shoe box to make it displayed movies and records the number of cards collected each time you receive the card. FELDI design uses Redboard, 7-segment display, LED, and IR transmitters and receivers to jointly build this circuit. When the card or candy scroll down the slope inside the box, the IR transmitter / receiver triggers the circuit to start the counter and the LED lamp.
7: Valentine Blink: Wireless Led Hearts

A user of Arduino Project Hub [Adik] designed a pair of wireless LED love, as long as these two hearts are close to each other, they will start "heartbeat". This design adopts several Arduino Pro Mini 328 development boards (a development board for each heart) to drive a large number of Neopixel LEDs mounted on the plastic housing in the guest shaped PCB. Each heart is equipped with an NRF24L01 RF (RF) module that can communicate with each other within the wireless signal, and the drive LED flashes in the same way.
8: Internet Valentine
(Source: Becky Stern Via Instructables)
The manufacturer Becky Stern also designed an exciting Valentine's Day, as long as the instruction is received from the paired another device, it will vibrate paper and make the LED flash. This Internet of Things (IoT) Valentine's Day gift is designed based on the ESP8266 Wi-Fi module, but also uses a pair of buttons to trigger each action. When the ESP8266 receives the corresponding IFTTT gateway service instruction, the mini disc motor in the vibration is started with paper love, and lights up red LED lights. Becky also created two versions for this Internet Valentine (but all using the same components) - a mash box package, and the other is encapsulated in the old design box of Radio Shack.
9: Dead bug Valentine

[Wrightma] DEAD BUG VALENTINE is not a point in design and small organisms, but refers to a new method of using another direct welding without using PCB. He hangs 8x8 ht16k33 LED matrix in line-shaped love, which is directly welded to the Attiny85 MCU and is powered by a 3.7V LIPO battery hidden at the display base and covered with decorative small stones. The Arduino Uno and Genuino will program and test this DEAD BUG Valentine, respectively.
10: IoT Interactive Valentine's Day Wreath

Protocentral's IOT Valentine's interactive loop can be close to the footsteps of the lover, so that this LED is getting faster and faster and traces how many people in this range. This design uses Protocentral's Kalam V3 development platform, GPIO CAP, ESP8266 module, VL53L0X Lei TOF sensor, and Neopixel LED. This LED design provides information from the TOF sensor and transmits its information to the cloud with Tweet; it can also display the programmed response message, such as someone com close :) or other content programmed to the platform.
If you know some soldering and programming skills, you will not be too complicated in this design. Although there is no need to become an expert, even if you have some professional skills, people who have some professional skills really create original design, can you have fun, and this is not the spirit of Valentine's Day?
Also, if you are still in a single state, then you should take it down as soon as possible, because I believe that you can find TA that makes your deer hit the TA soon, and these sweet rises are about to be used!
