Description

Snap Circuits® uses electronic blocks that snap onto a clear plastic base grid to build different circuits. These blocks have different colors and numbers on them so that you can easily identify them. Build the circuit shown by placing all the parts with a black 1 next to them on the clear plastic base grid first. Then, assemble parts marked with a 2, then parts marked with a 3, and finally, parts marked with a 4. Note that there is a 3-snap wire between the FM module (FM) and the speaker (SP), partially hidden. Install three (3) “AA” batteries (not included) into the battery holder (B3). Turn on the slide switch (S1) and press the R button on the FM module (FM). Now press the T button and the FM module scans for a radio station. When a station is found, it locks on to it and you hear it on the speaker (SP). Adjust the volume using the adjustable resistor (RV). The resistor controls the amount of signal into the power amplifier (U4). Press the T button again for the next radio station. The module will scan up to 108MHz, the end of the FM band, and stop. You must then press the R button to reset at 88MHz again.

    • Easy to put together and make it work
Color: Red
Our 10 year old son was bored at his grandma’s house this summer, so we sent him this kit. He had a great time putting it together. It didn’t take him very long to figure out what to do and once it was finished, he was showing everyone how it worked. The pieces are good quality (nothing broke when he had to take it apart to pack up his suitcase when it was time to come home. He was able to put it back together later and show us in person how it worked. And it does work! You can change the channel and find what you want to listen to. This can make some annoying noises (I can’t remember what my son did to it to make it make an awful noise) but if you have assembled correctly and find a station, it’s fine. It’s not very bulky and is easy to take apart and put back together. Our son had fun building this so we ended up getting him more circuit kits. These are great! ... show more

    • Multiple projects over and over
Color: Red
This is such a fun no tools required activity for little ones! The child we gave it too made the FM radio in about 2 minutes and was so proud they now carry it around the house playing it. They also take it apart and put it back together for kicks although they haven't made the other activities with it yet it appears that's not necessary and they love it! Depending on the child some adult help may be required but the directions were easy to follow and the pieces snapped together well. ... show more

    • Great learning device!
Color: Red
My 9 year old son absolutely loved putting this together with his dad. My son loves to play the radio on the toy HE had a hand in out ting together. He was so proud that he took it to school for show-and-tell. It was very easy to out together but taught enough about how connections work. The instructions were very thorough. ... show more

    • It works and it’s easy for kids and me.
Color: Red
This is an amazing kit. It is easy to put together and it works . It’s also easy to take apart for the kids to do it again. The base on this kit is rather flimsy compared to the robust bases on the other kits. The Snap Circuit kits are a wonderful way to show electronics to kids and they can do them with the very simple and easy directions. As Grandparents we will be buying more of these kits. ... show more

    • Follow directions exactly!
Color: Red
This is an excellent circuit board set for an 8 year old. You have to accemble the pieces exactly as the picture shows, but radio works very well. Volume is plenty loud and your child will feel so accomplished "building" a radio on their own! Great value. Battery life is good.

    • Fun, but directions for additional projects not very clear
Color: Blue
We purchased the Snap Circuits Jr. kit a couple months ago (Christmas present) for our 5 year old son because we thought he'd enjoy it. We underestimated how much: we thought he'd like it, but he LOVES it-- to the point of obsession. He spends hours a day building circuits and really has learned quite a bit. He expressed excitement and enthusiasm for acquiring other kits (he's built every one of the 101 projects in the SC100 kit at least a dozen times at this point...). So when it came time to acknowledge a job well done, I thought this little kit would be a nice reward (some of the snap circuits kits are very expensive; these mini kits seem quite reasonably priced). He was really excited to build a radio because some of the parts are different than what he has in the Jr kit- specifically the adjustable resistor, amplifier, and the FM receiver (plus a higher voltage (4.5v) battery, it runs on 3 AA) they may be redundant for other kits, I'm not sure. In any case, he was very excited, and was able to assemble a working radio in a short time (I helped him the first time, but he subsequently was able to take apart and reassemble by himself no problem). He was delighted. He was really excited about the additional projects, too (there are 3 other circuits you can build from this kit) but the directions are very difficult to understand. The radio circuit is depicted pictorially (as are all 100 circuits in the SC100 kit) but for some reason, the additional projects in this kit are not pictured; there are just written directions and they are difficult to understand. My son is a very proficient reader, so that's not it (even I was having a hard time deciphering the instructions, and I have a college degree). It just seems like a couple more diagrams would make this kit a lot more user friendly. For anyone else with kids that like this kit, check out the SC100 and 300 kits. My son can't wait to upgrade and is asking for the snap rover kit for his birthday in a few months. He's hooked. Overall from both a fun and educational perspective I've been really satisfied with these toys. As far as durability, what we have has been experiencing heavy use for a couple months and so far has held up well. There are little improvements to be made here and there (I also intend to review the SC 100) but overall I think they're great and if the enthusiasm persists, I see us buying more. ... show more

    • Hours of entertainment
Color: Red
FM radio has become a mystical thing for younger generations. This entertains my kids as they scan the stations for their favorite songs and make fun of local radio ads. Plays happy birthday and some other sound effects.
