Heart THT kit – angled front view with glowing LEDs

Average rating of 5 out of 5 stars

Heart THT - A special heart with a very special chip

Hearts are always good! And this heart is a homage to a very special chip: the NE555, 50 years old and one of the most widely used chips in the world... Still is!From mobile phones to blinker kits to satellites, this beautiful chip is used everywhere! In this THT heart kit, the chip sits appropriately in the middle on the circuit board and drives the pulse of the heart. The heart itself consists of many red 3mm THT LEDs with a so-called tracking circuit. Two LEDs light up at the same time and follow each other... whether they will ever reach each other? In addition, a switch on the back can be flipped to make the heart glow permanently. Of course, in the chaser version you can set the speed of the chase yourself with a potentiometer. Translated with www.DeepL.com/Translator (free version)The best thing is: With this soldering kit, even beginners can easily solder a heart for themselves or as a gift. There are a few through-hole components to solder, and it looks like a lot of solder joints at first, but the kit is still relatively easy to solder if you follow our good illustrated instructions. You just have to follow a certain order, then soldering is no problem at all!Target groupThe electronic soldering kit is designed for beginners. Adults and children alike can have fun with the THT Heart soldering kit, although you should not let children solder alone. Relatively large components are used, which make it easy to learn how to solder. This is also possible for absolute beginners in a reasonable amount of time. And the shape? Of course, you must have soldered a heart for yourself or your loved ones at some point in your life. It's best to order one or two at the same time, because as you can imagine, the heart is a popular gift for friends, partners or children.The components in the NE555 heart soldering kitOur kits always contain all the components you need for soldering. Unfortunately we cannot send you the batteries. However, you can get them from DIY stores and larger supermarkets (more on this below under "Tools and accessories"). The soldering kit includesThe circuit boardsThe circuit boards are the heart of the kit. They form the outline and the space to solder all the components. The circuit board is made of fibreglass material which is coated with a gold alloy. A multi-coloured lacquer layer is applied on top.The NE555On the board there is one smaller and two larger chips. The smaller chip is an NE555 that acts as a bistable flip-flop to provide the necessary clock. The two CD4017s (the larger chips) then dutifully count through all the LEDs and ensure that they light up.The LEDs and the other chicken foodOn the front side, many red 3mm THT LEDs are put through the board and soldered on. Even when switched off, this gives you a wonderful heart. But as soon as the circuit is powered up and switched on, everyone's eyes get big! Apart from that, there are some switches, slide switches and some chicken feed, i.e. other components.The battery holderWhat would a circuit be without power. Power is provided by a CR2032 battery that is securely fastened in a battery holder. The circuit itself and also the LEDs need relatively little power, so you can run the heart for a very long time with one CR2032.One push switch and several slide switchesOf course, there are also a couple of switches included! The push switch is easy to operate and therefore ideal for children (and adult hands). The switch locks in place and stays in the position (on or off) you want the switch to be in. A great perceptible "click" provides haptic and acoustic comfort. A slide switch sort for continuous lighting or chase LED.Tools neededHow the minimal soldering workstation looks like is described here: Der LötarbeitsplatzTo light up the NE555 heart, you will need to get some batteries from a DIY store or a large supermarket/shop.Also, an electric side cutter is very helpful for this kit :) Instructions and helpTo make it easy for you to solder the kit, we have put together detailed instructions with lots of pictures and individual steps for each of our kits. There you will be guided step by step through the assembly and there are many tips and tricks on how to solder correctly. For the majority of our soldering kits there are also interactive circuits with the names of the components and the tracks. All instructions are available in German and English.For environmental reasons we do not print our instructions. In fact, it is better to view them on screen, as you can then zoom into the high-resolution photos to see details. On each kit you will find a QR code or link to the instructions.You can find all the instructions as PDF files at the following link: https://binary-kitchen.github.io/SolderingTutorialJust click on "DE" or "EN" for the right kit and you can download a PDF.Lovingly packed for you by handAll soldering kits are lovingly packed for you by hand in Germany.

BleepBot kit – fully assembled circuit board with all components soldered
BleepBot - The robot that speaks to you

BleepBot – An Electronics Kit with Personality The BleepBot is a unique DIY soldering kit that produces electronic sounds in a fascinating and seemingly spontaneous way – full of character and quirks. At its core is an ATtiny25 microcontroller, brought to life by a clever trick: one of its pins is clipped before soldering, so it is not connected to ground (GND). As a result, this pin "floats" – meaning it becomes highly sensitive to electrical interference from its surroundings. This makes the microcontroller behave unpredictably, generating random sound impulses through its tiny speaker. It’s as if the BleepBot responds to nearby activity – or simply does its own thing. It almost feels like it senses your presence – and speaks back to you. The result is an interactive sound experience somewhere between tech toy, sound art, and electro-poetry. Perfect for: Beginners in soldering & creative makers Workshops, educational contexts & tech outreach Anyone who enjoys sound experiments and unusual electronics Kit contents: 1 × BleepBot PCB (circuit board) 1 × ATtiny25 microcontroller (pre-programmed) 1 × Speaker 1 × CR2032 battery holder 1 × Slide switch 1 × 2N3904 transistor 1 × 10 kΩ resistor 1 × 100 nF ceramic capacitor 2 × blue LEDs Battery not included: requires 1 × CR2032 coin cell The BleepBot invites you to explore – not just with solder, but with curiosity. Let it "listen" to your presence – and maybe it will answer with a cheerful “bleep.” The BleepBot is a collaboration between: noisio – creative electronic kits from BerlinAlwin Weber Circuit Control – a festival for DIY electronic culture Metaknoten – a cultural and community collective

The assembled Blinketree soldering kit Christmas tree with all LEDs lit
BlinkyTree – Interactive LED Christmas Tree Soldering Kit

The BlinkyTree is more than just a glowing decoration—it's an interactive electronics project that responds to you. With its ATtiny85 microcontroller as its “brain” and an electret microphone as its “ear,” this Christmas tree comes to life. Features Interactive control: A microphone detects when you blow on it and starts the music. Background music: Plays 7 pre-programmed Christmas melodies. Audio-reactive LEDs: The 13 LEDs dance in sync with the music and light up differently depending on the pitch. Realistic candle flickering: A sophisticated algorithm simulates the gentle flickering of candlelight. Completely open source: Firmware and documentation are freely available (CC-BY-NC 4.0). How it works After switching on, the BlinkyTree starts with a small animation in which the LED rings light up from bottom to top. The tree then switches to candle flicker mode, in which the LEDs light up in random, natural patterns. The real fun begins when you blow hard into the microphone: the ATtiny85 recognizes the signal and starts one of the pre-programmed melodies. While the melody is playing, the tree lights up the LEDs to match the melody – high notes light up at the top, low notes at the base.

Heartbeat soldering kit completed: heart-shaped PCB with pulsing LED in hand – finished project

Average rating of 5 out of 5 stars

Heartbeat – Pulsing Heart LED Soldering Kit for Beginners

The Heartbeat soldering kit is a heart-shaped PCB with a red 5 mm LED in the centre that pulses at regular intervals. The circuit is built from discrete components – no programming, just classic electronics. The board has a red solder mask, gold edge, and a pixelated heart shape that looks like it came from a classic video game. At the centre sits a large red LED that simulates a heartbeat. The circuit is based on the "eternal blinker" design by Malte Pöggel and Burkhard Kainka. It uses an astable multivibrator: a 100 µF electrolytic capacitor charges slowly with low current and is discharged in a short pulse through the LED, which also provides the necessary voltage boost so the LED can light brightly from a single cell. The circuit is very low power and runs for about 1–2 months on a single CR2032 coin cell. The heart is an ideal gift for someone special and works great as a Valentine's Day present. Despite the discrete design, the parts are easy to solder and the kit is suitable for beginners. The kit includes all required components (battery not included) and a detailed instruction sheet. Contents: 7 resistors, 3 transistors, 1 LED, 2 capacitors, 1 PCB, 1 battery holder. More background and circuit details: Heartbeat THT soldering kit on blinkyparts Wiki.
