Just an 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. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Im going to be looking into this more and finally i’ll be building up the circuit. What it also does not have is Bluetooth, but since it uses the more current op sys 3406a3 op sys supports Bluetooth. The board above was adapted to now become a high efficiency smart charger for a 6v battery.


It went together pretty quick in about an hour, I think it took a couple more to write it up and photos, scan the schematic etc. It seems hard to get an external Bluetooth device to datssheet too, so im looking for other datashest. Replacement Transformer Started by ncag Today at 7: 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.

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 doesnt have that built in and im not sure if it ever will. So could you do a quick scope shot of this thing in voltage regulation? I was thinking of an entire inverted scheme, but this looks interesting too.


All the time however we need 5v regulation, so that means we absolutely have to use the voltage regulation mode of the ic chip.

All the simulations always show at least some deviation from the normal ripple. 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 dataxheet expensive datadheet have the carrier PCB included togther with the module.

Hello MrRB, Thanks for posting that circuit, it looks very promising. You must log in or register to reply here. Let me elaborate just a little. For a better experience, please enable JavaScript in your browser before proceeding.

But you may want to go with Bluetooth if you are interested. The Tablet load could be represented by a load that changes in value like a lower to higher resistance and then back again depending on mode of operation either strictly running the device or both running and charging or just charging, and if charging what state the battery is in.

But what it doesnt do is read RS The reason i bring this up in this thread is because im doing all this for a Tablet computer anyway, and also that if you havent used one for your test equipment you may be interested in looking into that. Media New media New comments Search media.

Basically it used the current limit peaks to shorten the osc period from I’ve even considered electrical stimulation of the touch pad itself in a dztasheet area of the screen but that would be exceptionally slow, too slow for my purpose. Operation is pretty simple; the PIC has 2 ADC channels, and monitors the battery voltage and current sense resistor voltage. This datashdet reduces the length of the on period.


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

The small Tablet computers make an exceptionally nice base for a number of different pieces of test equipment, a multi channel volt meter just one example. 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. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and dattasheet.

That would be very cool, especially if it was just the one USB lead. Hi MrAL, sorry I don’t have any tablet experience at all, not datasheett one.

Re the waveform skipping etc, that was not happening at currents over 0. Since the efficiency is 93 percent at 1 amp out this should work nicely.
