Product Description

Product Description

Create Working Electronic Circuits Snap Circuits Jr (SC-100) comes with 28 components to create 100+ different electronic projects. The pieces, which include snap wires, slide switches, an alarm circuit, a music integrated circuit, and a speaker, snap together easily on the included plastic grid--no soldering required. Each piece is numbered and color-coded to make identifying them easy. These components combine to create working circuit boards just like the ones found inside televisions, radios, and other electronic devices. With its easy-to-follow instructions, Snap Circuits gives your child a hands-on education in how electrical circuits work to run the everyday devices that they're familiar with. They'll also gain valuable lessons in building and in following instructions. The project manual includes large color illustrations and simple directions for each project. The projects include a sound-activated switch, a musical doorbell, a voice-controlled lamp, a flying saucer, and a light police siren. With these projects, children will experiment with things like electric switches, integrated circuits, digital circuits, fuses, and the transformation of circuit sounds into other sounds. Includes: Plastic snap-grid, 32 electrical components, and 1 project manual. Recommended for children 8 years and older.

Each piece is numbered and color-coded to make identifying them easy.

Simple, Fun Projects Let Kids Learn While They Play
With its easy-to-follow instructions, Snap Circuits gives your child a hands-on education in how electrical circuits work to run the everyday devices that they're familiar with. They'll also gain valuable lessons in building and in following instructions. The project manual includes large color illustrations and simple directions for each project.

The projects include a sound-activated switch, a musical doorbell, a voice-controlled lamp, a flying saucer, and a light police siren. With these projects, children will experiment with things like electric switches, integrated circuits, digital circuits, fuses, and the transformation of circuit sounds into other sounds.

Grow as You Go
Because the projects are arranged in order of complexity, kids can build on their skills as they progress through the manual. The lessons start out with a simple electric light and switch project that demonstrates how electricity is turned on and off with a switch. Further along, kids can put together a two-speed fan, create clap-controlled sounds, and more.

Design Your Own Circuits and Upgrade Your Kit
Once children have mastered several of the techniques introduced in this kit, they can use the components to experiment and create their own customized circuits and electronic devices. The Snap Circuits Jr. SC-100 can also be upgraded to the Snap Circuits SC-300, Snap Circuits Pro, or Snap Circuits Extreme with the purchase of a UC-30, UC-40, UC-60 upgrade kits, respectively. Kids will enjoy additional parts, manuals, and projects that'll take their kit--and their fun--to the next level.

Snap Circuits Jr. SC-100 requires two AA batteries, which are not included.

      Bought these as a birthday gift for our niece, who absolutely loved them. I always wanted to get these for some kid, and fortunately, the niece aged right into the perfect demographic for me to do so. Just having turned 6, I was afraid it would maybe be a bit over her head. I was wrong. Over the course of 40 minutes, we started knocking out one after another of the HUNDREDS of included projects. The booklet/instructions are well-written, easy to understand, and explains the how's what's why's and how's of circuitry. I enjoyed playing with it myself, and I'm in my forties. If you're not buying kids Legos, pay the premium, and grab a set of these.

      A lot of different circuits possible, and they have many examples for projects.
      The connections are strong and durable
      Only problem is they switched the photoresistor has been changed to phototransistor, and it's directional but the booklet doesn't show it. It makes it harder for the kid to build properly by himself, but I assume the learning curve would be short.

      Bought this (very far in advance) for my daughter for Christmas, as I was looking for something similar to the Radio Shack 200:1 type kits I had as a child. Unfortunately, those don't exist anymore - but this is pretty close. The instructions could use some work, as they do not really describe what the components are doing and it feels more like teaching them to build Legos rather than read or understand electronic components and circuit diagrams, but I can understand how it might be the best option given the limitations of pieces being used. The old Radio Shack units had springs and everything was wired together with (sometimes hundreds!) of little jumper wires. Granted, I suppose not much is really wired that way anymore, and perhaps this more "circuit board style" is more appropriate for today's kids (and adults!). Either way, she has really enjoyed playing with it and learning about dc current flow, how reversing polarity on the motor causes it to spin in different directions, and troubleshooting her circuit lead to an understanding of how diodes are only one way. It's achieving it's goal, and for that, it's great.
      What's not so great, however, is the packaging. It's two cardboard and plastic molded trays, and just a slip cover. It's very difficult to store, since anything other than sitting flat on a shelf will cause the slip cover to come off, the trays to fall, and pieces to go everywhere! It really needs a traditional, closing box. Will have to try to find something that is more appropriate to hold the pieces, which is unfortunate.

      Reviewed in India on November 7, 2016
      Size: 750 ProjectsVerified Purchase
      I have been eyeing this for sometime for my kids and when I saw this listed at an amazing price, very close to the prices available in the US, I grabbed it. It also reached me very quickly. Thanks Amazon.
      The product is designed to get kids excited about electrical / electronics around them. You could pull together a breadboard and several of these components at a much lower price. You would be still stuck with messy / a little unsafe soldering etc. or with ugly wires sticking around. While for some, that could be well be the 'charm' of 'rolling up your sleeves', I don't believe that is a great first introduction. Because much of the bandwidth will be spent trying to 'make it work'.
      Now this on the other hand, has really high quality board and parts. The manuals (there are 5 of them with this set!!) are clear and easy to follow. There is enough basic information on not just 'what' but 'why' you do them. For those who want more detailed information, you could easily pull more content online from the web.
      The way I chose to use it, was to get the kids (11 and 5 years) to pull together anything that caught their fancy from the hundreds available. They started attempting the very complicated stuff, but quickly agreed they would rather go in sequential order :-) The 'experiments' are organized in sequential order of difficulty / complexity. When they pulled it together, they got great satisfaction from making the bulbs flash / sirens beep etc. I would then ask them 'why they think it happened'. So without getting into complicated IC circuitry which would be above them, they started understanding the need for logical gates and how circuits work or computers 'think'. I then asked my 5 year old what logical 'gates' (OR, AND, XOR) etc. he would use for him and his friends to reach the play park and use various equipment (swing : only one allowed at a time, see saw : perforce needs two etc.) This was great fun for him and terrific learning as well. My 11 year old is now trying to seriously decide whether the 'oscilloscope' principle is best served for engineers or doctors.. and therefore what she should become when she grows up :-)
      Absolutely love it!! I wish I had these things when I was growing up.

      This I got as a gift for my partner. She is not technically inclined but the plans are easy to follow. Being able to build something that works and does something really encourages the user. It also gives me chance to explain what each component is doing to make the circuit work.
      If you have a kid interested in electronics or as in our case an older adult trying to learn about something new this is great.
      The kits themselves are well built and reasonably robust.
