The 808 series of key-chain spy cameras

When it comes to dirt-cheap video cameras, the 808 series of key fob cameras must be one of the most popular. A large selection of these can be found on These cameras are designed to look like a vehicle key fob, and they do a great job of that.   Most folks would look at them and have no idea that you have a video camera attached to your key chain.  However, for many people, spying isn’t the primary use for these camera.  They are commonly used to capture areal footage from a model plane, helicopter, or rocket.  Because these cameras are lightweight, they work well for this purpose.

There are several models of 808 key chain cameras, and the video quality and price varies widely between these models.  The model is simply a number, usually between 1 and 24.  When you buy one of these, the particular model should be specified.  If it is not, be careful!  The lower models have very low resolution and video quality.  I got one of those to use with my model rockets to get areal footage.  You can see the quality (or lack thereof) by taking a look at my rocket videos, or the video taken from my radio controlled Sky Ranger airplane.  The cost for my camera was about $12, and I knew what I was getting.   However, there are some sellers that will sell you a low quality model for $40 or $50 – a big rip-off.

If you’re looking for a higher quality camera and don’t mind a higher price take, the 808 #16 and 808 #26 cameras are some of the most popular and give you 720p and 1080p video respectively.   In addition to the 808 series, there are also some similar cameras that have become very popular.  One of those is the Mobius Action Camera, which is similar in specs to the 808 #24 camera and will probably be my next camera purchase.

How to build a model rocket on the cheap

Building and launching model rockets is not an expensive hobby, but a few days ago I decided to try my hand at building three small rockets from scratch – one for each of my three sons.

This video on the right explains the process. I’ll be adding a few more details to this page in the future. For now, here is a list of engines that will work well for this project:

Estes A8-3 – This is engine I’d recommend – a lot of fun without losing the rocket

Estes B6-4 – a bit more powerful

Estes C6-5 – This one will push a small rocket out of sight – good luck finding it!
