Charles A Jones commented on fibrewire's blog post Inexpensive Online Machine Shop"If you need, can use or no anyone who can use the same part you will save per part big time to order 5 or more. For my part I am looking at having done it was around $172 plus shipping. If I order 5 of them it was under $190 before…"
fibrewire replied to Radu V's discussion Heavylift variable pitch quadcopter"can you get the ratings of the motors, and then plug all of your variables into the formula found here to get an idea of how much this quad can lift"
fibrewire commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"True, but the minds behind military weaponry aren't hell-bent on killing everything. I would impose coded-modulation for a game of quad copter lasertag!"
Axure commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"Indeed, I'm not interested in building a bomb targeting device. I would be content if I had a drone with a laser rangefinder."
Lew Payne commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"@Axure - if your definition of "us" is you (i.e., Axure), then I guess that's true."
Axure commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"But that's of no interest to us."
fibrewire commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"Yes - lasing a target was only half the problem. Using coded modulation made sure the right bomb got to the right target. IIRC, each bomb had their own unique address assigned right before launch."
fibrewire commented on Chris Anderson's blog post One huge quadcopter!"When I say large blades, I mean blades that serve the same purpose as an airship. So these blimp-blades would be covered with photovoltaic film, would make the variable-pitch quad rotor extremely light, and make it possible to cruise high altitudes…"
fibrewire commented on Chris Anderson's blog post One huge quadcopter!"How quickly can the control surfaces be changed? Back in the atomic age, people thought they would get rocket packs and fly around. Now that the general population is more mature in aerodynamics, we can see the value of larger control…"
fibrewire commented on Chris Anderson's blog post One huge quadcopter!"That was one of the first designs I thought would work. Boy, was I ever wrong!

Lew Payne commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"@fiberwire - Very interesting factoids on the beryllium! I suppose the coded modulator was also an important part of the laser targeting system. By the way,here's a beryllium glass selling for $8.95 (USD)... quite affordable."
fibrewire commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"Also, the visible light filters for infrared and lasing were matched. They were made from Beryllium.
One interesting aspect of the Beryllium filters is if dropped, the liquid gold colored filter would explode into pixie dust. Blast doors…"
fibrewire commented on fibrewire's blog post Gyro-Stabilized PTZ Gimbal for UAVs"When i worked on Lantirn pods for the USAF, the lasers weren't that powerful. The wavelength and filters were the most important aspect of the laser target designator / rangefinder.

Gyro-Stabilized PTZ Gimbal for UAVs
Posted on July 18, 2011 at 7:30am 16 Comments 2 Likes
I am an ex-USAF Avionics Sensors guy, and I have always wanted a gyro stabilized laser targeting system. Now that I am all grown up, I'll settle for a gyro stabilized camera.
A little looking, and I found some nice UAV equipment.It's a little out of my price range at $10,000 for the day system and $20,000 for the FLIR system. http://store.micropilot.com/category-s/21.htm

Continue Rule of Thumb for Power to Lift
Posted on March 23, 2010 at 11:57am 1 Comment 0 Likes
1 horsepower = 7 pounds
I've come across this magic number using different sized rotors, props, and engines in large RC helicopters and planes, and also researching horsepower to lift divided by time in several ultralight and light sport aircraft and rotorcraft, and this is a good rule of thumb when developing something that needs to do more than hover or drift in the wind.
Guidelines for precise calculation of…

Have you asked yourself "It would be great if I could get this part, but smaller" or "i could use this but it needs extra flanges or tubes or whatever" then you're in luck
check it out - you get instant part price quoting from the ***FREE*** CAD software program
A little patience goes a long way!
