Quadcopter of Harald Sattler

The top of the sNQ Shorty looks much tidier than its big brother, here the experience gained with the first work increases. The cables between the control unit and the LEDs and the motors are now laid on the underside of the circuit board and lead through the holes to the pads provided for this purpose.

sNQ Shorty – Quadcopter of Harald Sattler

“After initial flight tests I can confirm the function of the Mega328 with 16 MHz at 3.3 V operating voltage. Of course, one must be aware that the chip is operated outside its specification and no one can guarantee that the two chips and the ?C function are compatible with all possible conditions. It may well be that the shorty in the living room at 20 ° prima flies, then one opens the door and there comes cold air into the room, the copter simply crashes.”

“With the sNQ Stretcho, we pushed the motors down as far as possible through the brackets, because this would dampen or even suppress vibrations due to the engine running, and disturbances of the IMU chip largely fall away. In the case of the sNQ Shorty, this can only be implemented to a limited extent, …”

Automobile Ideas from 2002

Some things i had written online around 2002 on cars.

Cars can have multiple skins like Winamp

If you use organic flexible LEDs, encapsulated in transparent poly-sulphone or some silicones. And the RGB triad matrix of LEDs are driven by a computer system to make it work like a flexible LCD screen. It can be used to form a skin for a car. Only there will be no high resolution, but it will do.

This flexible layer is fixed on the car like a permanent cap. Now with the onboard graphics synthesis embedded car computer you can choose any jpg, png or gif textured tile or make your own. Then output the tile or wallpaper to the car exterior LED matrix skin. Now the Car has become skinnable. Not just colors but fine textures are possible.

Now with a Bluetooth enabled Human Mood Monitor plugin you can make the car exterior to reflect the mood of the life-forms inside. This will make a road alive and traffic jams very colorful.

Simple Automobile Safety Radar

There must be a very affordable automobile radar with just a 10-20 feet radius around the vehicle. This should display as a graphic on the dashboard as some of the very old 2D car games. This radar must be based on sonar or infra red to avoid additional EMI-RFI pollution and confusion. The display should show all objects which include people, small animals, kerb and wall.

The sensor has to be a multiple sensor, static belt one near wheels and one at the roof of automobile. The display device on car should be TCP-IP so that you can monitor your vehicle with your cellphone, PDA or any browser.

Thermoelectric Breakthrough can Replace IC Engines

IC Engines or Internal Combustion Engines are used in all types of Motor Vehicles. They convert Organic Fuel to Motion by tiny combustive explosions in a Cylinder-Piston arrangement. The use of Electricity here is only the spark for ignition.

Revolutionary Balloon Anti-gravity Car

These have a very low efficiency analogous to the Incandescent Tungsten Filament Bulb, The traditional bulb is being replaced by the emerging Energy Efficient LED Lighting Technology.

If we can convert Ethanol Fuel to heat by combustion, that is easy. Then the entire heat is absorbed by Thermoelectric Cell Arrays, like the Solar Cells absorb The radiation from the sun. The EMF from the Thermoelectric Cell Array can be a cascaded to generate enough electricity to charge the Rechargeable Batteries in an Electric Vehicle.

The most important thing is ….. The Material/Compound that can give a good Heat to Electricity Conversion, has still not been discovered. This has be as good as a Solar Cell.

Some Breakthrough in Semiconductor Physics, Nanotechnology, Material Science or Electrochemistry by the Scientists in Fundamental Research and Applied Science, can make the Internal Combustion Engine Obsolete.

Thermal Electricity can also make possible, ‘on the fly’ Electricity from anything that can burn. Coal, wood, twigs, dried leaves, biogas, ethanol can fire Mini Thermal Engines; that make Heat into Electricity to drive Electric Motors backed up by supercaps or rechargeable batteries.

The only other way is to offset gravity as shown in the right, this was a graphic i made in 1999 for a poem on my website.

Thomas Driemeyer – Bicycle Guide

“I often get asked about bicycle maintenance and repairs, and tips for how to ride efficiently. This little manual is intended as a summary of what I have learned over the years. I am not a professional mechanic.

Thomas Driemeyer – Bicycle Guide

All of what I say here is the result of personal experience and opinion and may in places flatly contradict professional techniques, but it has served me well. I offer no guarantees that it will work for you. If your bicycle falls apart because I said something wrong, you are on your own.” – Thomas Driemeyer .

Computer-controlled LED lamp

Computer-controlled LED lamp

This page shows how to build a lamp using this module that can be programmed to show any color or cycle of colors, as instructed by a PC or Mac over a serial RS232 line. (Or USB, using a cheap USB-to-serial adapter – unfortunately USB cables cannot be longer than about two meters before they become either unreliable or very expensive.)
