Fun to build. First I found a build video and then the instructions in English. They were not necessary. I only wanted to know what resistor and capacitor would be needed to enable a beep function for Morris code. I made two and they both work equally poor. After playing with the tuning I was getting better sound but broke off the speaker coil tab with the stiff wires included putting it back in the housing so I did not get to test the range after adjusting the tuning. The frequency is close to my old cordless phones I still use and it is what makes them most interesting.

Strong blue clear leds'. Sensitive at close range. Intense light. May want to make more and hook them all together to follow moving sound source and see if it will discourage it's barking.

Nice FM receiver with crystal clear reception. This was my first surface mount solder attempt and I was relieved to see it working after having been unable to actually see the weld on the micro USB. I could only see one side with my strongest magnifiers on but the electrons could find it and the charging light finally turned blue after a long wait. It took about six hours to charge. I had to enlarge the hole for the USB to line up and it shorted out my computer until I changed the cable to one that would not jam the connector by having a bigger end that would rest against the acrylic and it works great. Sadly I shot industrial dust spray liquid on the case by accident cleaning and crazed the warm acrylic and it left tiny cracks in the edge of the case. I may add a magnetic USB cord adapter to it for easy hook up.

This was a fun kit to build. I was intimidated at first to soldering the chip right but with good magnification a clean tip I had good results and the radio works well. Generally it does tune in the first time when you push the power button and you need to turn it off then back on and it will tune and play fine once the light goes out on the digital display. The sound quality is fair for a compact radio.

Fun to build. Nice PCB with wide spacing that is easy to solder. Diffused blue LED's make harsh blue light easier on the eyes Mounting holes and only three volts needed. I would like instructions in English but did not expect them to be.

I got this to replace my old Grundig that died from a severe electrostatic discharge from having taken three steps in my high voltage socks before touching it. It has good reception and bandwidth my old SW radio did not have It lacks the power output in the phone jack to power old computer speakers I was using and I needed a usb cord to save the batteries it eats in no time. I am happy with it because the price was an order of magnitude lower than what I zapped to death and it has already survived numerous small sparks and been blown out of the window by a fierce wind gust and tumbled hard, it will serve as a satisfactory alarm clock.

DeepShabad How did you assemble it without a schematic, instructions or values printed on the PCB?

Excellent little kit. Perfect for teaching a child how to solder (supervised of course!!). Some components are a bit hard to identify......watch the resistors & inductors!! Just waiting on some addtional purchases before I can power up and test.

Fun little amplifier kit. Ultra compact and easy to build with extra pins to hook up connections. The sound is alright and it works great off USB power. It has only one channel so you get mono and you will miss part of the sound if you input stereo.

I enjoy this white noise generator so much I ordered a second one. I like the dual output that allows you to hook up more audio power in case you need to make it roar like Niagara Falls to drowned out the incessant barking of your neighbors dog. It will make you relax and help make unpleasant sounds more tolerable. I was a surprised how sleepy I got when I first tested it. I am considering altering the next one to play with the sound output. I keep it on standby for sonic peace and sound health.

Beautiful, I can't wait to install it in my latest project. Until then I can use it to check voltage on other things. I seems accurate and the wire connection looks vulnerable so I may shoot some hot glue on it for protection. I choose blue to represent voltage since it is like the color of lighting and I like it. I would use red for current to be symbolic of it's nature.

I love it. This is the most fun of all the gliders I have and as a life long aeromaniac I have had many aircraft but not a crafty as this one. Once I twisted the ailerons to compensate for the motor's torque and get it to fly straight during take off I worked great and would circle a couple time and return close by. Fortunately I did not figure out how to get it to go on the longer flight time or I may not still have it because my field was too small. I like the decals this one has and that it say's Glider in English and Chinese so so know what it is. It lights up nice and really looks cool flying in the dark.

This was fun to build every thing went together minus a plastic stand off that I reproduced with nice acrylic that I had on hand. I added a fuse and a toggle switch that is most convenient and something that makes it much easier to use. Since this is a DIY kit you have the opportunity to customize it as you choose which makes it fun. It is does not output much current so I can see why some makers wanted to upgrade the transformer. It will be interesting to explore some off other functions with the DIY oscilloscope and have it power it's own analyzer.

I like this kit it is my first scope and it seams to work just fine for my needs. I added a pin to the display mine only had 19 but there were 20 holes for the IC . luckily I had an extra pin header and I added some extra hardware and acrylic spacers and glued it securely so it was solid as a rock while preserving access to to circuit board if need. I added a handy battery holder and it is totally portable.

Ερ: I can't get this to work at all. It is totatlly and completely frustrating. It does not work. I tried it on two different computers and all it will do is ask me to connect a device. Is mine unit defective?
