## Questions & Answers

**Q: Lights stay on? Check Q3 or Q4**
A: Hello:Since there are no Q3 and Q4 positions on the pcb, is it possible that you meant T3 and T4?  If so, you may want to verify that T4 has the BC557 component installed correctly.RegardsRegards

**Q: Can you disconnect the microphone and connect the input directly to a speaker output with a resistor?**
A: Not the best way to go about it but yes, it could be done being careful not to over modulate the input.

**Q: Is there a way to modify this to work at 12v so it would work with LED strip lighting?**
A: Technically yes, but you would have to add a transformer to raise the voltage to 12v, and reduce the number of resistors or their resistance values.....In short, this isn't the kit you're looking for to do what you're asking.

**Q: Do the LEDs all come on at once or do more light up as the sound gets louder?**
A: Hi Grant B.,

The led's only react to sound and not the loudness of it.

    Great entertainment!
  

*by D***O on Reviewed in the United Kingdom 🇬🇧 on 12 March 2016*

As a kid I used to do a lot of electronics projects with my dad, I'm talking between 8 and 14 years old. But since then I haven't done much, apart from an electronics course I had to take in college.I recently decided to get a bit more into this sort of stuff and thought one of this kits would be a good starting point to refresh my memory in the soldering techniques and all that.It probably took me 2 or 3 hours to build this, so not too long, it's easy enough and the instructions are quite good actually. And the most important thing, it worked! My wife was impressed, my baby daughter loved it and loved the fact the the lights would blink to her noises.I'm attaching a few pics of the progress as I was building it, oh yes, and at the end I did a little simple modification of my own, just installed an on/off switch.

     I used to do some extremely simple soldering projects as a kid and now wanted to start over in electronics so ordered this alongside the tools to test those out. It's really great, was easy to put together and it works, tried it against a synthesizer and all the flickering is quite spectacular. The only downside that it was probably a bit too easy to assemble, so even if you're a complete beginner I'd recommend considering slightly more advanced kits. Other than that, great!

### ⭐⭐ 2.0 out of 5 stars







  
  
    Very very poor
  

*by A***. on Reviewed in the United Kingdom 🇬🇧 on 28 August 2019*

This is the third (and last) Velleman project I've bought.  Each time the components and the PCB have been very poor quality.I've a long history in soldering PCBs and although out of practice I know what I'm doing so when the contacts flake off I know it's not a quality product.I bought this as an introduction to my 10 year old boy, it got 2 stars because we at least got to spend an hour together before the crushing disappointment of his project not working took hold.
