Hottest day ever lol so just to add to the heat lets build a big indoor hot air balloon for @lpoolmakefest and then spend ages test filling it with a heat gun! If that wasn't hot enough... check me out in my @oshwassociation bandana! If ur interested in these hot air antics we did a piece on them in @HackSpacemag 61 when @rpimag were but a twinkle in their eye. https://magazine.raspberrypi.com/hackspace/issues/61 #making #ConcretedogsFlightLab

Been working on this Drop Pod Parachute Deployer aka the DPPD! Need to make a better spring and then work on an onboard microcontroller system. #making #ConcretedogsFlightLab #MessyDesk

Remember that @FreeCAD #prototype nosecone from yesterday? Got the first prototype loaded up with a single LED and a battery, the little lengths of light pipe work well. Video doesn't capture the colours well tho! #making #ConcretedogsFlightLab #rocketry

Hmm. I appear to have brazed glass together with plastic! Gonna try again with just one sheet of glass. :) #ConcretedogsFlightLab #Fail

Little attempt to anneal some tiny #rocket fins using the glass plates I cut earlier. Lots of little developments happening in #ConcretedogsFlightLab

Also today, my twin boom supercapacitor free flight design (article soon in #HackSpace Mag on @[email protected] press ) had some flights... it does like collecting the walls though! #FreeFlight #Flight #ConcretedogsFlightLab

Fun afternoon testing out supercapacitor powered Rogallo wing models! #Flight #ConcretedogsFlightLab

Working on a self deploying Rogallo wing. Whilst testing will be blowing this out of a tube, eventually it will be deployed from a small #rocket :) #rocketry #freeflight #ConcretedogsFlightLab

All canopied up! Ready for test chucks along with lots of other prototypes! Can't wait for the next indoor flying session. #ConcretedogsFlightLab #Rogallo

Fun morning laying up a pattern for the larger Rogallo prototype. It's going to be ripstop just glued on for this prototype. I can imagine sewing one with sleeves and pockets down the line. #making #ConcretedogsFlightLab
