I don't often leave comments on YouTube, but I wanted to thank you and your sons for the truly excellent videos you have been producing over the years. This channel is a genuine gem, along with Applied Science, Breaking Taps, MarcoReps, The Signal Path... Thanks again, and please keep up the great work.

Taking advantage of phase angle firing to trigger at the apex of the wave form, using a 20 dollar dimmer switch, is brilliant. Thanks for the outstanding content.

Our world needs more people as smart as you

"Don't try this at home", "you can do this yourself, it's a lot of fun" I love this channel.

13:30 The capacitor in that circuit is absolutely necessary. Automotive coils like those are designed for 12v to be pulsed across its primary winding by an igniter for a few milliseconds (called the dwell time), if the capacitor wasn't there the primary winding would be subject to much higher voltages/currents for much longer periods of time. The capacitor in this instance is working to limit the total amount of charge that can pass through the primary winding in any given 180 degrees of the input.

Still a very good build overall, pretty impressive.

When most teens, tweens or even adults seem to care only about streaming entertainment, games or consuming instead of DOING something, this channel is such a relief! The channel itself and the comments are a spark of hope that we as a species may not doomed after all - at least on the very short term. Thank you and wishing the channel all the success it really deserves.

[DryPowder]

Like all your other content, you keep on delivering. Thank you for the inspiration and teaching. Lost track of how many young people I've encouraged to subscribe. Keep it up!!

[TheSpicySpeaker]

Thanks for providing the seriously important STEM knowledge you have! So much knowledge, so little time.

[ted]

By far my favorite tech channel. Your explanations are thorough and interesting. Great job!!

[AJ-qvyo]

I really enjoy the scientifically precise language and words when you describe your projects. Also using the metric system makes it easier to follow for us European tech enthusiasts.

[senorjp]

It's been a pretty crappy day here. This video was a high point. Thanks for your videos, Tech Ingredients.

Really have been enjoying this series. Not only the tips for greater performance, but really the tips for increased safety. Even in cases where a safe current dump can be achieved in 15s, MP improves upon this and ensures the current is dumped in 1s. Top notch, 10/10.

[danieltoone]

This has been an amazing series. I know you probably have no shortage of ideas for future videos, but some things I would love to explore with the help of some of your sage advice: plasma actuators (for aerodynamic control with no moving parts), railguns, perovskite solar cells, supercritical CO2 (and its applications), and all of the different types of electric motors.

[LenKusov]

What I've found works quite well, is readily available, and extremely cheap for continuous electric ignition is to take a Bosch Quad spark plug, bend the prongs as far open as they'll go, and hook it up to an $8 Sabre stun gun. Works well for gas burners, potato cannons, etc. so unless the arcs aren't "hot" enough I'd guess it would work decently for a jet engine too.

Really love this Jet engine series, pls continue with the double (in series) turbo charger plan you talked about a while back.

[tigerrsl]

I love these videos, they are packed full of useful information. I am searching salvage yards here and there for a used turbo off a big diesel truck.

I would like to make one point on commercial aircraft engine starting. Commercial aircraft can only start with air pressure. Either the aircrafts APU or a ground based ASU will be used to spin up the engines. The high pressure bleed air off of the APU is one method by which the engines can be spun up. The other method, is a ground based start cart or auxiliary start unit will be connected to the aircrafts ductwork under the plane. Most major air ports prohibit the use of APUs on the ramp. Ground based power, PCA (preconditioned air), and ASU will be connected to the air craft when it pulls up to the gate.

[NimodNamboodiri]

I am from India and I am a regular viewer of your channel. Very much inspiring. Your video explains the theory very well and exhibit practical result. No one else do that. Your explanations are a class apart. I am promoting your channel too. Thanks a lot, expecting more

[fraliexb]

I would probably never build anything you do videos on. I just love the science you put out there ❤️ keep making videos.

[cyndicorinne]

Great as usual. I like how you explained the starter by contrasting the alternatives. I was just rewatching your hydrogen oxygen bubbles video which indeed brought a smile to my face. And now picking up again with this video I feel back in business.

[ShanesGettingHandy]

Thank you so much for the information regarding your spark ignition setup. This is incredibly informative.
