Initiator Starter Set
This starter kit has been the standard introduction to high-power rocketry (motor types H and above) for 20 years, and for good reason. The Initiator rocket is big (39″), looks sharp, and can handle a wide variety of motors with its 29mm reloadable motor casing. You can put the kit together in an evening with 5-minute […]
3-in-1 All-Terrain Robot
I’ve been building OWI robot kits since the mid-1980s. Some have been good, a few not worth the box they came in. Every once in a while, OWI does a kit that’s great — their 3-in-1 All Terrain Robot (ATR) is one of these. This entertaining kit, suitable for kids 12 and up, lets you […]
Compressed Air Rockets Kit
I was looking for something to do with the kids. They raved about how much fun the rocket launching was at Maker Faire, so I brought some of that fun home with this kit, which is based on Rick Schertle’s project from MAKE Volume 15. The kit is an easy build, one or two hours […]
F.A.T. 3000 Guillotine Trebuchet
I’ve built my share of catapults (see MAKE Volume 28, “Gravity Catapult”), and this floating-arm kit has thoroughly impressed me. The parts come pre-cut in solid ash, and you clip off tabs to remove them, just like the plastic models I built as a kid. A file will help clean up the tabs. It’s put […]
Astra 1
Hobby rocketry leader Estes Industries makes more than a dozen inexpensive launch sets (launch pad/rod, launch controller) for beginners, but their included rockets are either pre-built or not much of a challenge. For a good first build, I’d instead suggest the Quest Astra 1. Its balsa fins are mounted “through the wall,” making it easy […]
Medieval Battering Ram
Desktop battering ram? I think yes. This small kit is a lot of fun to build and use. It takes some time to put together and uses a fair amount of wood glue, but the instructions are clear and easy to read. The kit comes with two ½”-thick boards that are CNC’ed out with all […]

Ginger Ale
The Brew It Yourself Ginger Ale kit is a great weekend project for the whole family. It comes with easy-to-follow instructions, ginger ale flavor extract, yeast, a funnel, and two blank labels. My kids enjoyed measuring, mixing, and heating ingredients, proofing the yeast, and bottling in two 2-liter bottles, adorned with their custom-made labels. After fermenting […]
Big Daddy
A few rungs up the ladder toward high power is Estes’ Big Daddy, a chunky, 3″- diameter model. While designed for D and E solid rocket motors, it can easily handle AeroTech’s 24mm F motors. It’s not much more difficult to build than the Astra, but bear in mind that an E motor has up to […]
Desktop Trebuchet
RLT Industries has gone above and beyond with its Desktop Trebuchet kit. Each piece of wood is carefully chosen and precisely computer-cut. All the required tools can be found around your house or at a hobby shop, and the instructions are very detailed. However, as instructed, I used wood glue on the main frame and […]
Siege & Ballistics: ballistics, desktop, siege, tabletop, trebuchet
The Truth Meter
See what happens when someone asks you questions or when you laugh or get surprised. Everyone responds differently. See if you can turn the LED on with your mind. Try it on your friends or adversaries — it’s a great way to get to know someone! We’ve even included a few extra resistors, so you […]
