<div><br>
<div><span style="font-size:10pt;line-height:1.5">Egg Timer Rocketry is having a sale. It happens once a year and you can get their rocketry electronics (altimeters, wifi switches, deployment computers, GPS trackers etc.) for $5-20 off. The gear is generally very affordable, from $15 for a dual deployment altimeter to $70 for the cheapest GPS receiver/transmitter kit. The catch is that you have to <em>build</em> the electronics from a kit. You get a bag o' parts - everything you need from pcbs to solder to heat shrink - and a link to an assembly PDF with detailed instructions. You supply the soldering iron, some tape, and your time. The simple kits take less than an hour to build, the more complex ones can take two hours. </span></div>
</div>
<div><span style="font-size:10pt;line-height:1.5"> </span></div>
<div><span style="font-size:10pt;line-height:1.5">As challenging as they are to build alone, I think they'd be fun - and a lot less stressful - to build as a group. </span><span style="font-size:13.3333px;line-height:1.5">They're not difficult, per se, but there are some tricks to working with the small parts and assembly techniques. </span><span style="font-size:10pt;line-height:1.5">To that end, if anyone wants to try out a build-you-own avionics I'm going to host a build party for the Eggfinder(/timer) kits in mid-January. I'm thinking around the last week of January would be best. If you get a kit, ping me off-list (<a href="mailto:jordan@truesdell.org" target="_blank">jordan@truesdell.org</a>). Presuming we have interest we'll set up a date and converge on a convenient location with soldering irons, magnifying glasses, and spare hands to put them all together and test them. </span></div>
