"Mini figure details are very nice. Tonto is really good looking. Silver can stand on its hind leg. Nice spinning Gatling gun. silver bars and nuggets are very cute. It is missing instructions to convert this into RC train set, but it can be done by putting the PF train motor and the AAA battery pack in the coal tender and the IR receiver in the locomotive steam engine. I motorized mine and added LED headlights, too. When motorized this train tends to be top heavy so go slow around the corners. Nitpicks: Smokestack should be bigger and black (see photo). Lego need to have a coupling rod for the counterweight flanged train drive wheels. Why Emerald green? Emerald is a rare color and makes upgrading difficult.."

"I love the AT-ST walker design especially the swivel head/turret - the cardboard box around the globe was torn and the instruction booklet was missing on my set - so I didn't have any instructions with my set but luckily all the parts were inside the globe and I was able to figured how to build it just by looking at the box art ( which turn out to be a bit more challenging). . I like the globe design on this one because it reminds me of earth. I'd like a set with the Clone War's ice planet Orto Plutonia (transparent blue?) with a Talz and one of their mounts/animals or senator Riyo ChuChi. with an ice speeder. yeah that's the ticket. Or maybe a black hole or Yellow Star set... :-)"
"This is a very simple build. The heart shape design is elegant and simple giving it a sturdy feel without the need to have many more pieces to reinforce it. However, the top cover swivels out of the way on a Technics pin a bit too easily - a latch to keep the lid from swiveling would have been a welcome design addition. (I would have use the another technic pin to do that). Another possible feature woule be studded interior compartiment which one could attach letter tiles or a printed tile saying "Be My Valentine". Ah but then it would cost a bit more than 4.95 would it? When I made another heart with a door hinge instead, i had to reinforce it to make it as strong as this orignal Lego design - AND so it was a more costly design and harder to build too - hence- I congratulate the designer for making such a sturdy yet simple design."
"Improved over its predecessor - it has more pulling power - especially at the lower power level range - this is very important since it doesn't draw power power from the train track but must draw power from the 9v battery pack. Unlike the Power Function M-Motor - the Power Function Train Motor does not have enough torque/power at the low current level (as supplied by four Lego Power Function Solar Panels) to pull a train car. So I'm disappointed in that respect. At high speeds especially when the track is not flat or the track is making a sharp turn - the rail wheels might lift off the track or slip on the track causing either a derailment or loss of power. There is sort of a balancing act between keeping rolling resistance down and maintaining enough wheel traction - don't know the answer to this one - I've seen a bunch of lego track modifications to deal with this problem...design works for modern diesel trains but notfor powering a working steam engine"
"The Red Cargo Train looks like a WWII era diesel track switcher, the Alco RS1. I found it an easy build. The train engine's smaller size made it more difficult to route the LED wires for with working headlights but it was not impossible. The coal conveyer belt loader and coal gondola car is a great follow up to the Yellow Cargo Train's Truck Container Gantry Crane. The crane-flatcar with the track gang car is good followup to the Yellow Cargo Train's Smartcar Transport flatcar."
"This is a straight current 3 pole switch that allows forward, stop, reverse ( there's also a black microswitch to reverse the switch's polarity). If this switch is between an "on" AAA battery pack and a motor it can put the motor in forward or reverse or it can turn the motor off . If this switch is between an "on" AAA battery pack and an IR remote unit, this switch will be fixed in the "ON" state (i.e. the allow the pulse modulated current from the IR remote unit to go through no matter what position the 3 pole switch is in) when the 7 speed IR sends a signal to go on. I was trying to use this switch as a kill switch for an IR controlled conveyor belt - until I realize this switch would not work with a pulse modulated current.
"This outputs a really nice soft white light. I used an array of 12 of these LED units to created a 24 LED flashlight powered by a hand crank dynamo which was bright enough so one could read a book at night if the book was about three feet away. With a Lego Education Energy Meter X1, I built a rechargeable Flashlight powering one LED assembly; The Energy Meter was able to power the LEDs from about 9.5 volts to as low as 8.0 Volts. The Energy Meter measured that the LED's current drain at 9 Volts was at .001 Amperes (.009 Watts). The only thing I would change with this particular LED design is the elimination of the black 2x2 brick that is between the wiring connector and the two LED lights - because more often than not the black 2x2 brick was was in my way when I had to do cable management. If I could add something it would be scaleable parabolic reflector to hold one or two LEDs AND a Lego-Power-Function-connector to the Legos-eLabs-connector cable."
