# What kind of igniters do you support with your electronics?

Altus Metrum in-flight products are designed to work with "low current
e-matches".  Most often, the ones available at reasonable prices are made
for use in the fireworks industry.  Local motor vendors tend to know how to
get these and other supplies like black powder and are a good place to 
start.  A number of Chinese makers sell e-matches on eBay at extremely 
reasonable prices, the best search to find them is "fireworks connecting 
wire".

High-current initiators like Estes igniters, holiday light bulbs, etc, are
unlikely to work.
