Problem is getting a BT adapter that works with the Android Tablet. Replacement Datassheet Started by ncag Today at 7: This would be easier to see with a wider time period for looking at the output ripple voltage. By continuing to use this site, you are consenting to our use of cookies.

With efficiency like that it looks well worth looking into for this kind of project.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at This language allows quick changes right on the Android Tablet so i can set up different things quite easily. Just daasheet update for MrAl, re an earlier conversation where I was going to build a 6v 10Ah sealed lead acid battery charger for a robot project.

The fig13 example should be workable fine for the PFET, it just needs to be inverted and then driven from the junction between the two resistors. The charger automatically selects between 7.

Im going to be looking into this more and finally i’ll be building up the circuit. Saves a voltage regulator i guess As you recall my original question was for a regulator for use with a Tablet computer, well on a xatasheet note, have you tried interfacing with a Tablet computer yet? These are stacked so to get battery voltage it reads the current then subtracts that reading from the voltage to datashdet true battery voltage.

To participate dayasheet need to register. Please note that when i started that thread i thought the BASIC language would somehow handle an RS connection, but apparently it doesnt as i have now read. But google Mosfet turnoff circuits. Operation is pretty simple; the PIC has 2 ADC channels, and monitors the battery voltage and current sense resistor voltage.


Is your goal to get your smart charger to send comms data to the tablet to display all the charging stats on the tablet screen? But i’d like it to be as versatile as the Windows based program panel.

The only ratasheet i am having now is interfacing my circuit datasheey the Tablet because my Tablet doesnt have Bluetooth. All the simulations always show at least some deviation from the normal ripple. Inspriation come from ETO member Mr Al who mentioned his interest in a high efficiency 5v supply to power his Tablet PC during power blackouts etc, see his thread here; http: It could be the Linux ones work but im not sure yet as i am quite new to this operating system and hardware.

Right now i have constructed quite a while back actually a four channel ‘meter’ that can measure voltages and with some simple interfaces can measure current too. It doesnt have that built in and im not sure if it ever will.

That would be very cool, especially if it was just the one USB lead. Hmm, if you want to use bluetooth for data interfacing to the tablet there are lots of cheap bluetooth modules on ebay, just watch out as some are just the “module” but need a carrier PCB which means you need to make a PCB, some are a fraction more expensive but have the carrier PCB included togther with the module.

I started a new thread about this subject a few days ago: That allows easy testing of battery cells of just about any type very versatile set up capabilities which allows testing of four cells simultaneously.

I was looking for 43063a 1 amp nominal output current with up to 2 amp capability.

It is shown for a N-chan Fet, reverse the diode and transistor polarity. Dataxheet the efficiency is 93 percent at 1 amp out this should work nicely.

Selling , , A with , , A Datasheet PDF of these parts.

It does support Bluetooth. Re the waveform skipping etc, that was not happening at currents over 0. What it also does not have is Bluetooth, but since it uses the more current op sys the op sys supports Bluetooth. Hi MrRB, That’s one goal yes, with the overall goal being able to monitor just about any process, and to start with to use the Tablet as a general purpose test bed for other plug in test equipment starting with a four channel volt meter.


I take it you can write tablet apps like a program to display the voltages? What i’d like to do is use the Android Tablet the same way, even if it means creating new software for the Android environment rather than Windows. From what i have read now some dont work and some do, so it’s a toss up.

This actually reduces the length of the on period. Potentiometer Questions Started by norbss Yesterday at Unfortunately, I can’t draw the circuit in my phone and won’T be back home until the 2nd of Jan.

So could you do a quick scope shot of this thing in voltage regulation? Basically it used the current limit peaks to shorten the osc period from Let me elaborate just a little. The board above was adapted to now become a high efficiency smart charger for a 6v battery. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Found some P channel devices, price range 1. So the bottom line is an interface to the Tablet that allows various uC based test equipment to connect and use the Tablet as display and eventually control input too.

It’s basically discontinuous, or very close to it, and quite erratic looking. I’ve even considered electrical stimulation of the touch pad itself in a designated area of the screen datasheeet that would be exceptionally slow, too slow for my purpose. That would be nice to see too and i could compare with my notes. Thanks for the link, this should help too because i have a lot of good N channel low Rd devices already on hand.

Personally I would prefer that dahasheet any RF comms as it will be higher datarate, simpler and probabl more reliable.
