Hi Granddad .... very common circuit , known as a dc/dc converter ,or boost/buck converter , it turns dc to ac then back to dc (ac is easier/cheaper to manipulate than dc )
@@GrandadIsAnOldMan boost/buck are only £1 but only rated at 4A (maximum) enough for led's but only small motors i/p 3V-32V o/p 5V-35V ...DC-DC Adjustable Boost Buck Step down Converter Voltage Module Power Regulator N (ebay uk from china)
@@bigfoot9911 yes you can always buy them but there are plenty of people who would rather make them for themselves to learn how they work. Just depends what you purpose is. Many of my projects are about trying things out for yourself but I admit I do also buy stuff. As it happens I did a recent postbag video on buck converters ruclips.net/video/B-_8DToirTg/видео.html
@@GrandadIsAnOldMan an old atx psu and a buck converter with digital readout,has been my cheap power supply for some 4yrs now ,the current limiting is handy (lm259 chip based ) AKA julian ilett buck psu
Has someone been using this as a hair trimmer. LOL Very interesting to see the boost converter for the LEDs. Just shows the thought that goes into the design and manufacture of something that looks so simple. Great video. 👍👍👍
Yes, I have had several of these little cars and the flexitrack to go with them and it suddenly stuck me they run off single 1.5v batteries so it was interesting to see how they did it.
Great video James!
Hi Max, you OK 😁👍

Yes, I put a link to an example circuit in the video description for anybody who wanted to build one for themselves.

The fact that this thing is faster than many of these cheap RC cars is absolutely insane to me 😂.
Looks like the led isn't so bright
Slap a lipo in it 😂😂😂
😁👍
Interesting
It played abracadabra by tiggy but speaker broke
It's over powered
It is designed to go over some pretty challenging track designs 🙂
Do you play pubg
No I don't
