Lately, this project of implementing solar cells into a homemade 4.68 meter glider platform has been neglected, though have considered to complete it to one's needs.If someone is interested in…Continue

I came across a thread which reminded me of regenerative braking. Not sure how much this relates with UAVs, but it's a fair topic to review.In my mind, mechanically storing momentive energy when…Continue

First of all, let me start by introducing myself, as I am publicly very new to DIY Drones, though have been following my obsession since I can remember. Unmanned Aerial Vehicles came into focal range…Continue

"Andreas, may I ask what the hold up is with DroneCell code debugging? I'm willing to get onboard if you have any recent updates on the improving code, for APM2.0 especially.
Thanks_"
Devin Johnson-Kinlaw replied to Devin Johnson-Kinlaw's discussion Conventional Aerodynamic Constraints On Aircraft Today: Problems > Solutions"I know. Wait for the model. Still ordering CF CNC parts. Also, need to employ several formulas for proof in the design process. I'll bring this into scope later. Expect EXP1 to be finished by around June 8th."
"Hmmm... too many big words."
Devin Johnson-Kinlaw replied to Devin Johnson-Kinlaw's discussion Conventional Aerodynamic Constraints On Aircraft Today: Problems > Solutions"I will be updating experiment 1 in several weeks. Basically, two adjacently spaced smaller static carbon fiber rings will repel a larger dia carbon fiber ring using surface flush Neodymium-Iron-Boron magnets of ultra-small size. This will simulate…"
bGatti replied to Devin Johnson-Kinlaw's discussion Regenerative Braking"It's a great idea: in flight it must be called regenerative soaring - and used to convert thermals into stored energy.
The challenge I believe is redesigning the ESC so it can achieve this modality.

I came across a thread which reminded me of regenerative braking. Not sure how much this relates with UAVs, but it's a fair topic to review.In my mind, mechanically storing momentive energy when braking is practically most efficient as one conversion is required with few direct losses, whereas adding electrical conversion is less kinetically direct (Momentum > Mechanical > Electrical > Mech > Force).Also, attaining maximum energy requires that kinetic momentum be converted to…See More

"As for me, right now, I am working on a circuit to allow for different modes of direct control over the GSM/GPRS cellular network. Currently, I still advocate the uploading of new waypoints and directional constraints to the aircraft…"
