  1. Love the data. The spikes in the 70s on System pieces look suspect. $3.31 per piece in 1975? My parents were buying me 300-piece universal sets in the 70s and I'm sure they were not paying $1000 in inflation-adjusted dollars.

    I have a question about Lego's IP usage.

    You should take a look at the Fair Play guidelines that Lego has had for many years: https://www.lego.com/en-us/legal/notices-and-policies/fair-play/ The short version is that Lego is very welcoming of fan-produced Lego-related content on the internet, they just have some ground rules they ask you to play by. Mainly, they want you to make it very clear that what you are creating is not an official Lego product. You cannot use their brand in a way that might confuse people into thinking your video was made by Lego, for example. There is a disclaimer at that site you can copy and paste into your video description that will let people know.
  3. It is from a Lego clone brand called Best-Lock. Your seller was not careful sorting his inventory!

    Yellowed Stickers

    This yellowing is probably caused by acidity in the paper and glue and is not easily reversible. Although it may be possible, it would probably also dissolve the glue. I agree that these are in such good condition aside from the aging, they look fine as is. I have had some luck with stickers that are darkened from dirt with simply soaking them in water with a little dish soap while they are still on the brick. You can rub the wet surface very lightly - use your fingers - to remove some of the dirt (much of which is often bits of the glue that have seeped around the edges and attracted dirt). Be careful not to rub off the top layer of paper that has the printing on it. Then just let it dry. Paper is pretty resilient.

    Help Needed Please

    Actually, I was surprised to find that these parts now ship separate in sets!

    [TC17] Solar Badger

    An idea for part of the Badger's defensive functions - armored plates that will extend to protect it!

    [TC17] Solar Badger

    Second prototype chassis. This one is already disassembled for improvements, but for the sake of documentation: I substituted the energy meter/storage battery for the rechargeable PF battery. The PF switch next to the energy meter switches between the solar cell driving a motor to the rear wheels or charging the storage battery. The storage battery output is then run to an IR switch with two small motors, one of which runs the rear wheels. The other one will power one or more functions. There's a gearbox in the middle (the blue handle) to select whether the rear wheels are driven by the solar cell or the storage battery. So it will have three modes - drive under direct solar power, drive under stored power, or recharge stored power with the solar cell. It is also possible to use stored power while recharging with the solar cell at the same time. This is mainly to get weight and dimensions, but I tried out some functions that will probably make it into the final version. I used a linear actuator beneath the solar cell so it can be tilted to the optimum angle to the sun. The survival technique of the Solar Badger is not to outrun or outfight other vehicles. But that doesn't mean it won't have some tricks up its sleeves!

    Colors of brick separators

    It's funny because back when there was just the larger older version and they weren't so common, I only had one and I always knew where it was. Now I have several and I'm always trying to find one...

    You can order them from the Education site. The set I got comes with a storage battery and meter, too (and some real wind vanes!). Or you can buy the cell separately. It can be connected directly to a PF motor. I got one earlier this year and have been looking for an excuse to try it out. The storage/meter device is OK. It has a maximum storage of 100J, which can run out pretty quickly. And there is no way to regulate the output with the meter itself. You can switch directions, but not step the output. But you can run it through an IR switch and control the output with that.

    The rat rod cab is top notch.

    I love those big red wheels so much I thought about just building my entry entirely around them.

    I built a "wireframe" to hold the elements of the solar/battery power source and get the weight and some basic dimensions. It weighs 489g and will move under solar input of a 250-Watt incandescent bulb. Next task is to load it up and see how much it can carry. That may set some limits on the power train, steering and differential. I'm planning some other functions, but they may end up being manual or pneumatic depending on how much I can eke out of the solar cell. It's geared very low, but speed is not the goal.

    Ooh - a winch! That's an idea...

    Thanks - My original idea was to use the storage battery from the solar set, but it weighs more than twice the rechargeable battery box. I'm going to do some tests to see what kind of load it can move and maybe go back to that if it looks like it can handle the weight. Ideally, I'd like to be able to have three modes - direct solar power to the motor, battery power to the motor, and solar power to the storage battery.
  15. I want to make a solar-powered vehicle that has battery backup. I connected two PF switches to switch between power sources. It's a pretty simple mechanical solution - turning one switch on turns the other one off. If anyone has other ideas, I'm interested in hearing them. One of the design goals is to keep it lightweight so it can be driven directly by the solar cell, so the fewer parts the better.
