Talking Clock Kit Review

Talking Clock Kit
Average Reviews:

(More customer reviews)
My scientifically/technologically minded 11-year-old son and I enjoyed putting the clock together. The level of difficulty has, in my opinion, been understated by previous analysts. This project seems most suitable for children of at least 12 years of age. The other problem we had was with the clockwork itself: The hands stick, so the sweeping motion cannot occur. The talking mechanism and its associated internal timekeeping mechanism work fine, and the alarm is functional.

Making this fun and educational talking clock will be time well spent. The easy-to-build kit helps teach you how electronic voices are made. No soldering is required and the full color assembly manual guides you step-by-step in putting it together. Clock features hourly reports and a rooster crow as an alarm option.

Elenco 300-in-One Elecronic Project Lab Review

I've always been interested in learning at least the basics about electronics and finally decided to do something about it. I bought a couple of 'intro to electronics', 'electonrics basics' type books and I bought this toy. While rated for 10 years and up, they'd be pretty bright 10 year olds. The kit comes with capacitors, resistors, diodes, wires, transistors and even IC's. The other reviewer is correct. Resistors are all color coded -- and very small --- and very many in this kit. I finally spent about 4 hours labelling over 50 tiny plastic bags so I could easily find the appropriate parts to do the projects.
The manual explains how to identify all the parts, and for the projects uses a step by step approach to instruct one on how to put the project together. For example, "Insert 100 ohm resistor in B12 and J12 on the breadboard". In this respect, yes, a 10 year old could easily follow these instructions. The diagrams show the breadboard layout as well as showing you the "real" schematics. That coupled with my reading through my "electronics for dummies" books -- it's actually all starting to make sense as to why components are laid out they way they are. Without the other books, I would not have figured that out just from this kit -- but, if you just want to make things flash and make sounds etc and follow the instructions, that that won't matter. The manual does attempt to explain why something works -- but I was lacking the bare basics, so it didn't make much sense.
All in all, I would highly recommend this kit to anyone who really has an interest in learning about basic electronics and wants to put things together.
It would be a great kit for family projects. However, there are a ton of very small parts and good eyesight or a magnifying glass and a flashlight would be recommended for those of us with less then perfect eyesight.
Well worth the cost, working out to much much less then $[money]/hour of enjoyment to work through the 300 projects.

Kids love to watch gears go! This smart set lets them put their very own contraptions together and then used the hand-held motor to make them spin. (Warning: Dad may want to play with this one sometimes, too.) With 10 pieces in all, it's a toy they'll have fun making new creations over and over again. Even better, you can use it with any Gears! Gears! Gears! building set. 2 AA batteries (not included) required.
