High quality, low price

I built the digital clock for use on my ham radio bench. The kit was complete and well made. The PCB (printed circuit board) is well made and of a size that even the eyes of an old man (me) can see clearly. Assembly is straight forward with no difficult parts to mount.
All of the parts were there and this kit is easy to assemble. A young builder or beginner could build it and learn about it from the experience.

Hi Michael, thank you for taking the time to write a review, we really appreciate it! Well done on completing your clock! There's a lot of soldering in that kit, 400+ welds, glad to hear you found it was easy to manage all the same. I see you've ordered other kits from our selection too - the most challenging one will be the FM radio because, unlike this clock kit, it does have some fairly small components to mount. Your FM radio kit should be with you in the next few days. Be sure to check out the detailed instruction manual that we emailed to you after you purchased the FM radio kit, as it contains lots of tips and advice on how to set those components successfully (if you've deleted/lost the email, the instructions can also be downloaded from the product page, or you can just email us at info@thesciencehut.com and we can send you a copy). If you need any questions answered during assembly, just email us - we'll be more than happy to help!

FM Radio Assembly Kit

I purchased the FM Radio Kit. It is a good-looking kit. With a ½ watt speaker, you will want to listen to this radio with earbuds. The instructions, which you can download, are well-written and will take you step-by-step through the process of building this kit.

One word of warning: if you are not experienced with a soldering iron, you should probably find someone to solder in the STC15W408AS chip for you. While the other two surface-mount chips can be placed by the method outlined in the instructions, this chip has an extremely low tolerance for errors. You will need a very steady hand, a small tip on your iron, and very likely some sort of magnifier. It can be done as per the instructions, but use great care. I used solder paste and a heat gun instead of an iron.

I experienced a problem with my kit that you almost certainly will not – some manufacturing shorts on the board. These were easily dealt with (I know how).

Depending on your experience, but especially after placing the IC (packaged) components, you should use a digital multimeter to check that things are connected where they should be and not where they should not be. This is to rule out problems caused by soldering errors.

One final note: Amazon sells this kit for $10-$15 less.

Hello Dennis, thank you kindly for leaving an honest and fair review. We really appreciate it. Also, thank you for the advice you've shared in your review; we wholly agree with it, and from our emails back and forth, we know this advice is coming from someone who is very experienced in electronics (so readers, take heed). We did share your feedback relating to the presence of shorts with the manufacturer of this kit and we're awaiting their response - we'll circle back with you by email once we have that to let you know the outcome. Your ability to create a working radio despite the possible faults is testament to your experience.

FM radio

Nice little kit. I'd wanted to build an FM radio using some of the all-in-one chips available, and this ticked all the boxes.

Took my time assembling - soldering some of the SMD components requires a very fine bit and a steady hand - but it was easier than it looked. Pleased to find everything worked first time and I got Mahler's 1st as soon as I tuned it to the local classical station.

Sound quality is not great, but the kit only has a 1 inch speaker, so not unexpected. Some components had to be moved slightly to fit into the case, especially the vertically mounted capacitors, which should have been almost flush to the board.

Only criticism was that the kit arrived without instructions. However I emailed customer service who immediately sent me a PDF (in English) with very full directions and colour diagrams.

I enjoyed building this and will probably buy other kits from your range.

Hi Andrew, many thanks for taking the time to leave this detailed review of your product. We're very pleased you had a successful build and were happy with the resulting product. As always, if you ever have any questions about a product or need help with and technical aspects, our customer support and technical teams are always delighted to help! Feel free to reach out if you have any questions relating to any other products you might be considering.

NO INSTRUCTIONS!!!

Please send me assembly instructions. At this point I cannot enjoy this product because it did not come with assembly instructions.
Help!!!

Hi Michael, thank you for your purchase. Detailed English instructions have been emailed onto you, I trust this will meet with your expectations.
