When I grew up, one of the toys my parents encouraged was Legos, since it allowed for a lot of creativity while they also kept on a tight budget. Since I now have some youngsters of my own, I enjoy building things for them to play with and helping them build as well.
This page will have instructions available for some of these projects – which I put under the “Battlin’ Bricks” name. All “Battlin’ Bricks” designs of them are compatible with the Brickmania™ designed “Micro Brick Battle” scale of approximately 1:120.
Here are some samples.
My prototype designs are sometimes available at: https://www.ebay.com/usr/doolittleraid
