35W Foldable Solar Panel Charger Kit for Smartphone Laptop

This is a really sweet model. The quality is high, the instructions for assembly very clear and all in all a wonderful product. The engineering that made this model at this price possible was formidable.

I wil say that the alignment of the cylinder and the beam fulcrum support is very touchy. I am experienced in these matters and I had difficulty. I had to leave the four cylinder mounting screws slightly loose so things would line up. Suggest a thicker base plate that has a ground surface. Also, the burner is definitely very touchy ad there is potential for spills and unwanted fires. Would love to know if the whistle is threaded in.

The instructions to build were fantastic, I soon got it together. There are no operating instructions but I have some knowledge about steam engines so I worked it out. The engine.wouldnt run continuous at first so I ran it at a steady speed for 10 minutes without the governor belt on, this allowed the parts to run in, I put the belt on and it runs fine now. Instructions about adjusting the governor would have been nice, but I worked it out. The short tube split after a few days running but I had some tube that size so not a problem, I am thinking about replacing it with a metal tube, but thats in the future. I run mine on gas, much safer than meths and less bothersome, I have some gas burners for my other engines so thats Ok.
I havent worked out what the plastic bits in the spares bag are yet, but I suppose I'll find out when I need one. As I say, some running instructions would have been nice, but it is a nice engine, well built and engineered.

Love it. Super simple design. Everything that isn't pre assembled is all put together with off the shelf M3 nuts and bolts. As for the main piston and cylinder. You'll have to adjust the beam a fair bit and run the engine hard to help work out the CNC machine lines. Both cylinder and piston where machined on the same axis so the tooling lines rub against each other and create a high friction zone. That said it won't run well at first. But after some time and wearing in those parts will loosen and performance will improve. That being said the novelty of this pleases this 30 year old. Beats using the space heater.

ENJOMOR Christmas Metal Steam-Powered Car Model: A Functional Science & Education Collectible Gift

My son gave me one of these "coffee-cup Stirling Engines" as a gift. Not only does it run for a half-hour or so on a single cup of coffee, you can also run it on the heat from the palm of your hand, if you put a bit of ice on top. (You might do this after a meal, if you have a bit of ice left over.) It makes a faint, musical clanking sound when running. A tiny bit of assembly was required, just snapping the connecting rods onto the cranks. It ran even better after I put a counterweight onto the flywheel.

All I expected

Yes there are better machined kits available but definitely not for this price. A true value for money kit, easy to build, runs smoothly, good at slow speed too and a joy to watch. Happy with the delivery time (netherlands) and well packed.

Quick delivery, good packaging for transport (no damage). Nice cardboard gift box as 2nd packaging. Beautiful model machine, carefully crafted. Very happy!

Fun to build.Works as it should.No pieces missing.

Got it in just two weeks, and man, this engine runs like a champ. The paint job and design give off some serious retro vibes – totally loving it!

I am an engineer and love old vintage stuff from the past. She saw this vintage engine on Facebook and gave it to me for my birthday, we have been married for more than 30 years and I really love her, thanks to my wife also thanks to Enginediyshop!

I'm a huge MOC fan, entered their Facebook giveaway, and landed this gem. It's insanely realistic, the structure is spot-on. Feeling confident in my skills, I decided to tackle it without the instructions – what a blast! At 10% completion, I had to here and share my excitement. Highly recommend it for fellow LEGO enthusiasts!

The price isn't too shabby either. It occupies way less space and makes way less noise than a full-size engine.
