“Dear editors!
Read in issue No. 7 article “Reinvent the wheel!”, long thought, what I’d like to see him. The picture I painted your project…”

“I read an interesting article about bikes. It is very good that the magazine raises the question of their modernization. I both hands “for”.

The advantages of a velomobile compared to a bike known to all. First things first- it is resistance, and thanks to her and comfort (although relative) is also much higher. I want to share with readers design another simple and compact recumbent. In the feature I want to include the word “universal” because it allows the drive to connect to the work in addition to legs and arms.
Universal tools do not claim to replace conventional designed to perform one or two operations, but in many cases, the care of equipment, its repair, adjustment is convenient to use them.
As in Yugoslavia, the southern country, fanned by the warm winds of the Adriatic, also like to ride a mountain on sleds? Love! And even come up with their design is such that it can g be used and we northerners in the snow in the Russian mountains.
In technical literature there are many publications on improvised electronic code locks — variety of complexity and management that is performed on chips as small and medium scale integration and microcontrollers. Unfortunately, most of the first it is impossible to quickly change the code, since it is necessary to solder a jumper, or make other changes to the installation. In others, although provides for reprogramming of the microcontroller, but a very limited number of times. Furthermore, these modifiable combination locks consume in standby current of approximately 1 mA, which makes pay attention to the selection of source of energy when you use the above devices in both local (field) conditions where it is impossible to use network adapters.
Bold, uncomplicated and, importantly, “volatile” model-copy will work if you choose as a prototype little-known light aircraft of the series Pixie.
