I'll bet glue sniffing was the problem. Legos snap together, so that's not a problem. I had the feeling that as the Lego models emerged -- they came in slowly -- suddenly Lego realized there was a real demand for instruction-based complicated toys. Then there was a whole wave of these toys.
Ann, I don't know why plastic models vanished. I would imagine you can still find some online, but they used be everywhere, from drug stores to grocery stores. There was a multi-year gap before Lego picked up the slack with their complicated toys that required detailed instructions to build. When I started buying them for my kids, I thought, "Wow, these are similar to the old plastic models."
AnandY, thanks for the laugh. I think it will be awhile before we'll have DIY kits for building *that* kind of bug. Or else they'll come with high-powered magnifying equipment. This bug is a beta version that will hopefully be improved by Dash Robotics' beta customers.
When I first heard of the word bug from your heading, the first thing that ran through my mind was the secret listening device used by secret agents and spies. I mean, the robot bug thing is inventive and fascinating but I hope in future it will be made into a more useful purpose other than being just a kids' toy.
Agreed, Ann - I never played with dolls when I was a kid. I had quite a large collection of horse statues though - tiny horses have my vote. I'm a big NASA fan and like your space idea too. Accessories really aren't a bad idea - it adds to the creativity of the project and makes it kid friendly. It's funny how some people think science and art are independent of each other. It takes a great deal of creativity to be an engineer!
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
