Comrade Power sent us a diagram and firmware of his device. The laconic description is fully compensated by other advantages of this device, the main of which is simplicity and diminutiveness.

Super miniature running light with five LEDs

Bonjour!

We look at the picture, we do the same, but with 5 LEDs.

Diagram:

Super miniature running light with five LEDs. Scheme of a running light for 5 LEDs

Details:

microcontroller ATTiny12L - 1 piece,
LEDs - 5 pieces,
resistors 1k - 5 pieces.

Firmware

The firmware was written using the program Algorithm Builder 4.80

The project files are in the archive led_chaser_5led.zip .

List of archive files:

ledchaser5.alp - the project itself
ledchaser5.bin - Firmware in BIN format
ledchaser5.hex - firmware in HEX format
ledchaser5.rom - firmware in ROM format
ledchaser5.lst - listing on asma

Vcc: 2.5 - 5V

If the power supply is not more than 2,8 volts, then it is possible without resistors.

Fuses for teens:

Bodlevel-1
Boden - 1
Spien - 0
RSTdisbl - 0 - most importantly, do not submit log 1 to RESET to start the controller
CKSel3 - 0
CKSel2 - 1
СKSel1 - 0
CKSel0 - 0

Hope I didn't forget anything...

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Ultrabook Toshiba dynabook V632 has 13 hours battery life 18.03.2013

Toshiba has announced the imminent start of sales in the home market of the new ultrabook dynabook V632. The novelty will go on store shelves starting March 20 and will cost about $1460. Perhaps the most important feature of the novelty is a long battery life: according to official data, the device can work without being connected to the mains for 13 hours. True, at the same time, the characteristics of the battery are not reported, it is only known that the battery is of the lithium-polymer type.

The equipment of the dynabook V632 is typical for the latest generation of ultrabooks: it is based on a motherboard based on the Intel HM76 Express chipset, and the processor uses a dual-core Intel Core i5-3337U, operating at a frequency of 1,8-2,7 GHz and supporting Hyper-threading technology. threading. The standard amount of DDR3-1600 MHz RAM is 8 GB. For data storage, a 128 GB solid-state drive is used, and the ultrabook display is characterized by a diagonal of 13,3 inches and a resolution of 1366 x 768 pixels.

In addition to the above components, the configuration of the device includes Wi-Fi 802.11b / g / n and Bluetooth 4.0 communication modules, a 920 thousand-pixel webcam, a Harman Kardon speaker system, an SD card reader, three USB 3.0 ports and HDMI video output.

According to the manufacturer, the body of the dynabook V632 is made of magnesium alloy and is additionally reinforced, and the laptop keyboard is backlit.
