Comments on the article
Below is a schematic diagram (printed circuit board with the arrangement of elements) of the simplest programmer for PIC microcontrollers.
A capacitance of 100 microfarads can be more; 220 microfarads are installed in the design in the photo. A 12,6v zener diode can be replaced with a 13v one. A capacitance of 0,1 uF can also be replaced with a larger one (0,22 uF is set in the design in the photo). The 2SC 1923 transistor can be replaced, for example, with KT 315. Diodes are used 1N4007.
Microcontrollers are inserted into sockets and flashed using a PC and the IC Prog program.

Machine for thinning flowers in gardens
02.05.2024
In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Advanced Infrared Microscope
02.05.2024
Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Air trap for insects
01.05.2024
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
| Random news from the Archive Wireless control of any battery powered devices
25.01.2013
Home automation is becoming more and more accessible, today it is possible to add remote control functions to household appliances without having deep technical knowledge. Once again, this was proved by the Tetherboard company, which demonstrated the Tethercell electronic block. Using this module, you can wirelessly control almost any device powered by AA batteries.
AA batteries are compact, and it is very difficult to supplement them with any external modules, otherwise the battery compartment may simply not close. Therefore, Tetherboard engineers went for a little trick, the Tethercell electronic unit has the size and shape of an AA battery, and inside it there is a place to place an AAA battery, that is, an even more compact, but less capacious battery. The free space is occupied by the control electronics, including the Bluetooth module as a channel for wireless control.
The system works extremely simply. The user replaces one of the AA batteries in the compartment with an AAA element in the Tethercell case, with a smartphone and the appropriate application, the result is a wireless programmable switch. The applet allows you to set timers and set a schedule for turning on / off any device, in addition, the smartphone owner receives a timely notification when the battery runs out.
It is reported that the Tethercell device was invented by a father of three children who harassed dad with the sounds of a toy electric guitar and ignored all the requests of the parent to stop this disgrace. Perhaps the only drawback of the gadget is the small range of the Bluetooth module. At the moment, investments are being collected on the Indiegogo portal to launch the Tethercell project into mass production, with an estimated retail price of $35.
