"Oh no, my phone is dead, let's ... start the steam engine" :-). In all seriousness, this little engine won't generate nearly enough power for charging a phone, but it's a cute idea.
@@RetroTechyNerdyStuff probably not, it makes me wonder if it could. How much horse power does that have (I know it’s a fraction of one) because all it needs to do is produce at least five volts or 18 watts of power. Btw, if you try this, please share my name. I wanna see that so bad.
@@diplexnormal3353 Classic USB is 5V and 1A, so 5 watts of powers. Some USB standard support much higher currents. I did a back-of-the-envelope calculation, according to which this little Mamod might theoretically develop something like 0.3-0.5 watts of power to the shaft at 900 rpm and 20 psi steam pressure. This is assuming no mechanical friction losses, and then we need a drive belt, a small dynamo and a voltage regulator, causing further significant losses. I have a gut feeling we'd probably be lucky to get 0.1 watts of effective electrical power. Subject to actual testing, of course ;-) Perhaps measuring effective power developed by the engine is a good subject for an upcoming clip.
@@RetroTechyNerdyStuff or you could push one of your engines to a near peak, im not saying to try to actually charge your phone by like 1 percent, just enough power for a phone to detect. I am by no means engineer but it’s just a thought.
SP7 is more powerful, if gas fired, of which, as far as I kmow, there's only one, because I have it 😁. Alas Mamod's quality put me off buying more and I've had a few. Some sold on, sxome still in the collection, for now.
The SP8 looks very nice too, and a few years ago Mamod also made a beam engine, the SP8. I too have been somewhat put off by Mamod's quality control. This is the only Mamod engine I've owned and it had several problems out-of-the-box. If I may ask, which specific aspects of the quality put you off buying more?
@@RetroTechyNerdyStuff it would take all day to air my concerns. Check out my shown and special traction engine call something like "has manor changed in the last 8 months". It will give you a good idea. They ate under new ownership now, so maybe things will change. I have a SP8 beam engine. One of the best I had from them, but the general enthusiasts didn't go for it.
@@PLAYINGAROUND You tickled my curiosity so I watched your video. Very interesting, and an excellent walkthrough of the embarrassing mistakes in the workmanship. Mine also had defects, although less severe, probably since it's a less complex engine with fewer things to go wrong. It's sad that quality is sliding with these engine, but to be fair to Mamod in my experience they are not the only steam engine manufacturer which has let the quality slide over the years.
Complete, only the pressure gauge is missing.
Ich werde das in Smart fortwo einfügen, danke.
Great, I can charge my phone now.
