Power Video Cutter V3.7 Ultimate Utorrent

[Margherita Gonyou]

<div>We researched and tested hubs with a number of different port layouts, ranging from models with just USB-A ports to those with USB-A plus power pass-through, video output, Ethernet connectors, and SD card slots.</div><div></div><div></div><div></div><div></div><div></div><div>Power Video Cutter V3.7 Ultimate Utorrent</div><div></div><div>Download Zip: https://t.co/L7AOzJDv9I </div><div></div><div></div><div>Since Arduino Nano is very small in size and cheap, it might be a good choice for a battery-powered project.</div><div></div><div>Clones are abundant on ebay and other websites for around 4USD and mostly come with CH340 series USB/TTL adapter, instead of the original FT232.</div><div></div><div></div><div>First, to save power, you will need a boost converter (or DC-DC converter) instead of using siz AA batteries or 9V batteries on VIN pin. The on-board converter is a 1117-5.0 linear regulator that is not very efficient. I recommend something like this:</div><div></div><div></div><div>You can use two AA batteries to power the converter and get 5V output. Supply it to 5V on Nano. I measured currents on the battery side ( 3V), not the 5V side, since I was trying to estimate battery life. I also measured currents on the USB side in case I use a power bank.</div><div></div><div></div><div></div><div></div><div></div><div></div><div>When Arduino is sleeping with POWER_DOWN sleep mode, the whole board consumes 15.5mA 3V from the battery. If you are using USB to power it (say you use a power bank), it consumes about 18.5mA. This is definitely not good enough for batteries. Even with a gigantic 20,000mAh power bank, the maximal time is 45 days. The efficiency of the boost converter and activities (other than sleeping) will reduce this to just a handful of days.</div><div></div><div></div><div>After this, you will have to remove the 1117-5.0 regulator to get more power saving. This step is difficult. I used a hot air rework station to carefully heat up the regulator and removed it with only a little damage on the male headers' plastics. If you don't plan on putting the regulator back, get a small flush wire cutter and just cut out the regulator at the pins. This should do:</div><div></div><div></div><div>So if some of you thinks this is not really what a "pico" processor promises, then I am sorry to tell you that the Nano just wasn't designed for battery operation. The CH340 consumes a certain amount of power even when sleeping. About 0.15mA at 5V so it could translate to 0.25mA at 3V. Its pull-up and pull-down resistors also cost similar amount of current draw. There is no way to remove the CH340 chip and still use the USB port. Using an arduino mini will solve this problem since it has no USB chip.</div><div></div><div></div><div>On a data logger I designed around ATMEGA1284P, I used FT232 but it will not receive power from the battery. The power consumption is about 0.4mA when sleeping. Not as low as it can go but good enough for 6 months.</div><div></div><div></div><div>Thanks. I'll experiment on those as well. My experience has mostly been interacting with 5V sensors so I've not tried 3.3V either, which should reduce power consumption as well. I should probably first try the internal oscillator at 8MHz and load code via ICSP to see how much power is saved. I'll post next week.</div><div></div><div></div><div>I've been designing data loggers for a while. The most recent design is kind of unique. The real reason I did the measurements was to see whether I should add a transistor to turn off peripherals on this data logger, which uses arduino nano. My initial tests were without removing components because I thought that would turn away some beginners that don't know how to remove these surface components. So I went ahead and did the design without the transistor. Now I see that removing the resistor (or even brute-force destroy it with a wire cutter) or even the regulator (cutting it out) would be quite doable for beginners, I've modified my design. The design is based on all thru-hole components cheaply available on ebay and elsewhere that spells cheap. The point is to make the design available for any beginners to assemble. My other designs are all surface-mount and with 1284P, lots of memory compared with 328P</div><div></div><div></div><div>Cool write-up Liudr! This summer I began making low power devices based on a naked Tiny85. Of course they need to be programmed externally, but they run well using the 1MHz internal oscillator at 3 volts. For my application, this is plenty fast enough. I've also been using the Narcoleptic library (GitHub - brabl2/narcoleptic: Sleep library for Arduino (compatible with arduino-tiny core)) as suggested by Simon Monk in Programming Arduino Next Steps. The library he points to in the book does not work with the Tiny85, but the one I've linked here does. It's a cool library, especially as it gives delay() a reason to exist.</div><div></div><div></div><div>as a note, I have two NANO's that suffered horribly at the ham-fisted user shorthing out power. both work great when fed with 5v on the 5v pin, but since the diode is burnt, both need some TLC to replace the diode, or some 'Jason' type slashing and hacking with sharp tools.</div><div></div><div></div><div>Hi, quite old topic, but very useful! Thanks, liuzengqiang.</div><div></div><div>Olilabrute, yes your suspision is correct. I check on my nano. I connected it to 3xAAA to 5V pin. With linear regulator, current consumption was 1.69mA (power-down mode). After desoldering 1117 it drop down to 0.23mA what give 1.5mA of quiescent current.</div><div></div><div></div><div>I have used a deep sleep mode as well as some hardware modifications to bring the power usage (in power-down interrupt sleep) to 60.000 times less than the normal (non power save) usage.</div><div></div><div></div><div>With features like a patent-pending, unique cast blade pan, the 2150 is setting the bar for flex-wing cutters.
