HASH(0x93aa8738) étoiles sur 5 Abysmally Poor Design 1 janvier 2011
Par Mike - Publié sur Amazon.com
I was so excited over this item I bought two - one for my 8 year old son who is a science enthusiast and one for my nephew. I was disappointed to find the amount of "assembly" required. I am no slouch - I have over 40 years of electronics experience and am even building a house, doing all the plumbing and electrical myself. But assembling this toy was just a drag. The worst part was having to manually wind the wire around the paper tube to create a tuning coil. It was difficult to do and my 8 year old was not even remotely interested in even watching me do it, forget his ability to participate. At one point the thing slipped out of my hand and all the wire came off - if it weren't for a lot of patience and luck, that would have been the end of the thing because the wire normally would be completely and irreversibly tangled at that point. Henceforth I kept a rubber band just behind my work in case it slipped again. Then the wire ends had to be stripped with sand paper. Then the wire connections were made in tiny screws with nuts - LAME. The "connecting wire" was insufficiently stripped to bend per instructions. The instructions were obtuse and overly complicated. Really it seems like an imbecile engineered this thing. I was so upset I got it for my nephew. I found out that my brother in law lost his grip on the thing while winding the coil and the entire thing was ruined - useless. Coil should be pre-wound and ends stripped. Connections could be made easily with little pre-mounted SPRINGS (hello, SLINKY corp???). It's not rocket science, guys. What a rip-off. I am never buying ANYTHING from this manufacturer ever again (unless it's a slinky). I have never written a negative review about a product before because who has time for that. But this was an absolute JOKE. No kid could assemble this damn thing.

We did get a couple radio stations, but couldn't hear well enough to even distinguish what we were hearing - what language, etc... A simple, single 1.5 volt battery module for optional amplification could have been included for about 25 cents of manufacturing cost. Really this toy was not thought out at all. I would say this thing cost about $1 to manufacture, package and ship to the US from China.

How much are they selling for????

RIP OFF!

HASH(0x93aa8a44) étoiles sur 5 Wrong detector diode included with the kit. 9 juillet 2011
Par John Boy - Publié sur Amazon.com

I was very excited to build my own crystal radio so I purchased this kit. I have about 10 years experience in the electronics industry so I figure it would be a snap! I carefully followed the instuctions and wound the tuning coil as described in the instuctions and hooked up the wiring correctly. I found a suitable antenna, the steam pipes in my house but I couldn't get any stations not even backgroud noise. Then I examined the detector diode, it was an ordinary silicon switching diode. The diode looked like a 1N914. I won't get into the technical aspects except to say that a silicon diode is not "sensitive" enough to "detect" the radio signal unless you were right under the radio tower. I replaced the silicon diode with a germanium 1N35 diode, which is more "sensitive", and tuned into several radio stations!

This kit would be great if it came with a germanium detector diode.

HASH(0x93aa8f84) étoiles sur 5 Would be a great activity, if only . . . . . 17 décembre 2009
Par C. Gookin - Publié sur Amazon.com
I bought 11 of these to use with my middle students. At first the students were enthusiastic about making a real radio. Our first problem arose when some of them did not receive enough wire to complete the coil. Why would they want to continue an activity without the proper supplies? Then we had problems connecting the extremely tiny nut and bolt assemblies that connect the wires to complete the circuit. The instructions are vague or incomplete in some sections. It is not always clear which wire they are referring to or which direction the diode should be turned to receive radio signals. To date, not one radio has received any radio signal. Mine has some clicking and humming sounds, but that's it. There is no trouble shooting or suggestions to help determine why one's radio isn't working. We have been assembling and reassembling them in hopes of finding out what the proper configuration is. Unless your child/student is a least middle school level, has an inquiring mind and a persistent nature, I would not recommend this kit.

HASH(0x93aa87b0) étoiles sur 5 it sucks 21 mars 2009
Par Russell Cassity - Publié sur Amazon.com
this product looks cool but it is not. it does not work and is very very hard to build winding the coil was very hard and hooking it up was hard plus it is not good quality its a toilet paper roll and a thin plastic breakable base. please listen to me do not buy it it does not work it is a piece of junk.

HASH(0x93aa8f90) étoiles sur 5 slinky crystal radio 2 novembre 2008

Winding the tuning coil was critical and ridiculously hard to do. Assembly of the cheap parts (toilet paper roll) and single plastic folding form was tough to get to stay fixed once assembled. Never got the radio to work although it did pick up some static.
