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, …”
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.

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.
delabs – 2006
“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
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.)
This project, called “Simple-Timer” is a programmable Timer and electronic switch with an integrated LiPo Battery Monitor that is based around a PIC microcontroller.
The “Simple-Timer” includes a fairly accurate timer that is programmable (via pushbutton) by the user and can be programmed to time a 5, 10, 15, 20,25 or 30 minute event. When the timer/switch is enabled (tap small pushbutton), the onboard LED indicates the output is active by lighting solid (the circuit also outputs the same voltage as your supply/battery voltage using a PN2222 NPN transistor or a high current MOSFET).
Bicycle Light Projects
Constructing or modifying a bicycle lighting system should be done carefully to enhance the lighting and not displace a minimum lighting that is needed for safety.In rural areas and mountain bikes more lighting may be needed.
Dynamo LED light electronics – A nice selection of electronic circuits to power LEDs from a bicycle dynamo
Battery LED light electronics – A basic step-up circuit to power an LED from a battery
- Universal single-LED headlight
- Universal triple-LED headlight
- Universal LED taillight mechanical construction
High-power halogen headlight from standard parts, battery-operated
- Lots of light for your money
- All standard parts, easily completed in half a day
This is a educative and simple example to help learn about supercaps and white LED. It will also help you understand component behavior. If you are learning electronics, try this one out.
The goldcap-Dynamo Lamp idea is a DIY Tutorial by Kainka on Electrical Energy Harvesting. What may be this EH Thing ?
Energy harvesting (also known as power harvesting or energy scavenging) is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor networks. – EH at Wikipedia
Then the Cycle Dynamo may not be the ideal choice for furthering this research. The reason being, this is quite a powerful source of energy, especially when going downhill!
Electric Double Layer Capacitor – EDLC
We need a more fussy source of Electricity. Like the waves of the sea, that could splash onto Large plates of Springy Beryllium Copper Cantilevers, which moves an Array of Magnets in coils (Reverse of Solenoids). This gives Random Spurts of High Energy Pulses which have to be Harvested.
Piezoelectric Energy Harvester – Mide Technology
That is for you to dare and do …….. Now let me give some things you can read, before you start this epic Adventure…
Electric double layer capacitor an eFlywheel
Now Move ! There is so much Abundant Energy to be Harvested. You can Even Setup a Roadside Electric Trike Recharging Station. – Gomier Electric Tricycle
We need more contests, An LED Lighting Contest and a Sponsored Elekrik Vehicle (Non-Car) Super-Contest.
