I had added battery holder link please check that and tell me how many time. Yes, this is battery holder which connect batteries in serie to achieve high
well for serial communication, you will surely need a microcontroller. There you have a UART port, but to connect it to PC you need to convert this TTL UART signal to RS-232, so u need an RS232 converter IC (max 232) or you can use FTDI chip ft232 for usb to uart conversion. ft232 has some gpio as well, so if your IO requirement is less, you can e
Testing of the usb charger circuit was conducted using a small solar panel and a car battery. The results are as follows. For small solar panel, the phone charges normally without any problem. When connected to car battery, phone keeps on changing from charging to discharging mode very often and does not charge at all. What could (...)
You mean for a car charger? Cheap chinese manufacturers do it like that, they also melt if you're actually pulling 0.5A (or more) 14-5 = 7V 7V * 0,5A = 3.5W There are plenty of usb current limiter chips out there, but all said and done, the 7805 is not the right choice.
I m using a car battery to run 2 usb chargers. There is a switching regulator circuit in between the battery n chargers to step dwn 12vdc to 5vdc and the 5vdc to power usb charger. That should be SAFE with such configuration ? - - - Updated - - - Is the switching regulator circuit sufficient to provide protection to the ch
OBD-II ELM327 compatible AllPro adapter There is RS232 and usb versions. What exactly you need, what car? You can see this circuits with ELM327
Hi all, I want to build a car usb charger using the 12v of the cigarette lighter. I already found a regulator for the job but how do i protect my circuit? I have heard that the 12v of the car varies a lot. Is a high power zener enough? Should i use a crowbar circuit? Maybe a low pass filter? Thank you in advance.
Thanks for the reply. Now you got me thinking :) I got a feeling theat the led's I got are not the best quality, i could be wrong, but i got a great deal on them from flea-bay,, why I bought them. I tried the 120 & 150 Ohm resistors, & got heat as I said. At first I over complicated the issue by having a usb car adapter included in the the desi
Hi, I have ZTE MF631 usb 3g data modem having an external port for connecting antenna . that port is CRC9 connector .. the professional antenna available in the market are to expensive too buy .. so i want to make an home made antenna .. i have that CRC9 connector and aluminum wire.. see the attached image to get idea how actual antenna i
I created a Mass Storage Device with a PIC18F26J50 and the Microchip usb stack. It works great on everything I've ever connected it to. However, it does not work on my car radio. I made a recording with a Beagle usb Analyzer, and the only difference between when it works and when it does not is one byte (in bold, at the end of the reco

Hi, I've been struggling to find something that can help me and I wonder if I can simply design something around. I have a car GPS, it has a single usb port which is used for charging it or to use as a usb host, I'd like to make an external battery to power this unit and at the same time be able to use the usb port to (...)

This can be better explained and guided by the vendor from whom you have bought the tool. Cheers Thank you, i had conneted the laptop to OBD-II through OBD2-usb cables and free software.
The first step would be the usb standard itself. I good website I've used as a usb reference is "Beyond Logic" (google it since I can't post links yet). Finally, if there's a particular IC you're interested in the manufacturer likely has an eval board that includes a SW stack. Hope this helps, Gavin
1. Can I make a usb out of the last 4 pins in the lower right part of the picture? The device supports only 9600baud. So you will need to wire a usb driver specific to this device to make it work for usb (It might be easier to use the regular Serial port). Also, you might need some line/port drivers to connect this to the
Hi, I bought a video camera Cannon Legria FS200 but I lost the charger which had a usb end. I have a charger for a car vacuum with a similar voltage (9.6) and I wanted to cut a usb cable and connect the end to the vacuum charger. What I have done is connect the usb black and red cable to the red and black from the charger (...)
In the following text I described how to connect normal audo device with mp3 player that consist usb slot for pendrive. For a long time I wanted to add an mp3 function to my old mini – audio system. Device is so good that I rally want to keep it. So idea was to insert some mp3 player with low costs. Choice was a car transmitter mp3 (...)

First of all hi, I am new here so i dont know many things, but I would like to learn. I am wondering how I can make a usb external port in my CD/MP3 car player. I dont remember the model but the brand is JVC, I will look for more details. Is it possible to make it?
Common place to tap off battery power on the car is the cigarette lighter. There are plugs available to easily connect to this. Here in the US, there are many cheap cigarette lighter plug to usb charger devices. What these contain is a version of the circuit pranam77 has shown above. (The only two pins of the usb plug supported are (...)
Hi all. I wish i can explain myself well, since i'm not good at english. Mmmm, let explain you the project. From a pc with bluetooth(usb-dongle) i want to send orders to a cellphone(with bluetooth) that is on a car. A microcontroller may get the orders from the cellphone by AT commands, and make the car move. My principal (...)
I use my laptop in my car on a daily bases. It only has 1 usb port and I use about 5 usb devices. I bought a powered usb hub. It works ok without power if you only use one or two usb devices. However, when I use more devices, they don't operate correctly. And it doesn't have enough power to operate my (...)
Do you need a usb microcontroller to do that? It will be similar using other microcontroller.
Hi All. I'm using my TYTN II to listen to radio when I have a long drive. The TYTN II is connect using a FM radio transmitter, with the usb converter. The problem: When using the Internet, then battery drain is quite fast, especially if you are on the move and the radio signal is not that strong. I tried few usb chargers, and all

Using VB is fine for this kind of thing. I agree that the tech used in door operners are more complex signaling schemes than just on off. However the use of Serial / Paralell ports on notebooks is becoming rare very quickly. You might need something like usb? If the notebook has integrated Bluetooth wont it be easier than WiFi. I know that Bluet
hey i got a quetion for you'll i'm intrested in building a car charger that will output both 3.3v(nokia jack) and 5v(female usb for ipod) i was thinking of using a simple 7807 and from there one to 7805 and one to 7803. i was wondering what protections should i put on the circuit and maybe some capacitors for voltage spikes? any help or tip would
