DIY Solar Tracking System Inspired by NASA (Parker Solar Probe)

In this video I demonstrate a simple autonomous solar tracking system that can be used with solar panels or parabolic mirrors to improve their performance in producing renewable energy. For this system I use two 10rpm, 6v geared electric motors, and four 5v, 0.6w solar panels connected in a configuration that allows the motors to constantly move the panels into shade (purchasing links for these items below). The cost of the electronics was about $10, and could easily be scaled up or down as necessary for a variety of solar applications. Check out Destin's video about the Parker Solar Probe to...

Ebay LED floodlight scam warning.

If you've bought or are considering buying an LED floodlight from ebay, then this video will show you some of the pitfalls. From unconnected ground wires to MUCH less than half the quoted power rating. I'm not sure why it's so common to see the earth wires left unconnected. The fixture is mains voltage and metal, so it should be earthed, especially when the cable has an earth conductor in it. Although the LED operates at a reduced voltage, there is still the potential for water ingress, electronic failure or bad manufacturing that could result in the casing...

Testing a USB powered wall hook and a look inside.

I'd like to thank John Harrison for sending me a link to these on Aliexpress. I've not had much luck getting stuff sent from AE to the Isle of Man so I checked for them on eBay and found that HMRC (UK tax) was blocking some Chinese sellers from shipping to the UK. I finally found some sellers shipping to the UK so I bought a couple from different sellers to be on the safe side. They both arrived together, and here's a demo and a teardown.

The High Pressure Sodium Light: Ubiquitous, effective, but good?

You can support this channel on Patreon! Link below Ever wonder why street lights are orange? For such a fast-paced world technology-wise, it seems somewhat odd that we are still using such a strange color of light for outdoor lighting. Well it turns out it is still a pretty good light source, though with limited use and perhaps a not-so-obvious flaw.

Dual Beam LED vs. Halogen in Reflector Headlights

In this video, I compare dual-beam LED to halogen bulbs in the reflector headlights on a 2012 Hyundai Tucson. This is the first time I'm testing a dual beam LED (high and low beam in one bulb). I perform a side-to-side test of brightness, coverage and temperature of these two bulbs in both low beam and high beam settings. Find these bulbs on Amazon - LED dust caps - To see all JDM ASTAR products, go to Support my channel and buy my shirt!

The shocking truth about cheap LED "corn cob" lamps

NOTE: CE does NOT mean China Export, it's just a mis-spaced CE logo (just like the one on the back of an Xbox 360). Comments mentioning China Export will be marked as spam automatically, because it's horseshit. Commenters trying to use alternative characters to bypass the spam filter get muted from the entire channel. Based on feedback comments on my earlier video and a request from the folks at, this is a shorter test on a range of "corn cob" LED lamps available on eBay and Amazon. If you're thinking of buying cheap LED lamps, whether it be online or from...

Inside a very clever LED headlight lamp.

This started off as a simple autopsy of a faulty lamp and turned into something so much more. It's a very clever design that makes the circuit very universal.

I'm not sure of the seller of this LED mislead me by telling me it was for UK 240V electric, but when I tigged on the solders it banged really loud. I do not recommend bying LEDs from bad people becauise they go boom and may scare you. And for those who actually read down to this level... The actual result of hooking a (really crappy) 100W LED directly across 240V was so boringly controlled that I had to beef it up a bit for a second take with hidden resistors underneath for some sparks and pops. See...

Dead LED lamp autopsy.

A look at a modestly high powered LED lamp that was one of many that had failed. Also discussing various LED power supplies. The phosphor loaded gel in front of the chips seemed unusually tough and plasticky. I wonder if it had baked dry over time or had always been like that.

Ebay $1.50 Filament LED lightbulb teardown (2W)

Teardown of a filament LED lightbulb from Ebay for $1.50 including shipping. Rated 220V 50Hz, the nominal power is 2W, real power is cca 1.6W, it has a E14 screw base. It is quite bright and looks nice, but there's no fuse in it. There's also no filter capacitor, so it has a lot of 100Hz flicker (not visible to the human eye unless you move it fast). It has a capacitor dropper in it with a 330nF capacitor, 1M discharge resistor and 1k inrush resistor. The 330nF multi layer ceramic capacitor looks quite small for the mains voltage. You can...

Philips LED Lamp 9.5W Teardown

A Philips LED Lamp which stopped working is dismantled to see what is inside. 9.5W, 220-240V. Warm white 2700K. The LEDs are 24 individual surface mount items arranged in series. These still work, the failure is in the power supply which unfortunately is potted in resin. Case is made from thick metal with a plastic coating over it. This was purchased in 2013, and has been used for 6-7 hours a day, probably about 5000 hours in total.
