content: Hi,I am going to share my latest project. It is called a BatterRUSEr. It comes from the words battery and ruse. For those not familiar with the English language a ruse is a trick or scam used to fool someone.link:https://www.google.ca/#q=ruseThis is not to be confused with the 'Batteriser'As usual I started with a LTspice model:I am using the LT3539Link:http://www.linear.com/product/LTC3539I have designed a schematic:I have also made a board layout:The board layout is single sided and I will make a prototype using my LPKF Router.I have ordered some parts. When the parts arrive we will see how this circuit works.Regards,Jay_Diddy_B

content: Quote from: Berni on August 20, 2015, 09:20:16 pmI doubt it.I expect that for low power drain devices with a proper under voltage threshold I expect the battery life to be shortened.The reason for this is that devices may use an LDO, and are therefore constant current devices. Higher input voltage means more loss in the LDO.At higher currents the efficiency drops, this is the published efficiency and power loss curve:I feel that the efficiency losses will offset any gains from the benefits of the Boost circuit.I will probably do my initial tests at 100mA. At this current a AA battery should last about 24 hours, which is a reasonable time.Jay_Diddy_B

This would be tricky.A frequency above the AM radio band, would be a good idea.I think we would see more air cored inductors if they were practical.Jay_Diddy_B

content: Jay,I've gone and recently done the exact same thing! I've dubbed mine the BUTTerizer, as the idea is completely butts, but I've made a similar circuit with the exact same LTC part and sent off to get my boards fabbed. They should, in fact, be in tomorrow.Since you simulated it, did the /SHDN line work in simulation? The datasheet says that the V_1 >=0.88V and V_0 <= 0.3V for the /SHDN line. I left a solder pad on my layout to either connect it to V_bat or use an external voltage source for the /SHDN line.My layout:Don't have an image of the schematic at the moment, but it's pretty much the same as yours. I did, however, use one of the LTC recommended inductors, a high quality one from Wurth. I don't imagine my design would ever fit in a battery holder; but I imagine that any design using as teeny an inductor as they are wouldn't be able to drive squat.(edit for spelling corrections)

content: The juries out, but I think Godzils design is the winner despite its complexity. Although it will only present the same regulation as a battery, we have to remember that BATTERIES are NOT POWER SUPPLIES!. All your fancy shmancy designs are in fact TINY POWER SUPPLIES and behave like POWER SUPPLIES, NOT BATTERIES. Godzils will act just like a real battery - even down to emulating the internal resistance. Also it's efficiency looks to be a bees dick as good as 100% as is possible.However, it is not a completed design and no physical prototype exists yet. I think Godzil needs a Kickstarter in order to pay for tooling costs, materials, coke & hookers, Ferrari, etc.

The output voltage is minimum 2V. They designed it to drive gadgets (way too noisy for anything important) from a single primary cell, and it costs 0.35 USD. I guess they are smashing their head into the wall, because they should have made the output voltage go to 1.5V.

content: Quote from: NANDBlog on August 21, 2015, 11:33:09 amThe 2V output voltage are needed, because this is the supply voltage for the ic. Until the 2V are reached, the boost converter runs at a fixed duty cycle to bring the output voltage up to the level needed for normal operation. The specified quiescent current is referenced to the output voltage. The current draw from the battery is therefore much higher.

It already couldn't fit in a battery compartment, so you know, just go whole-hog and make it as good as I can

content: I've been working on my own approach to this problem. The theory of operation is that I create a small black hole and take advantage of time dilation to make it seem like the battery is lasting 8 times longer. Its complete bullshit, of course, but my assumption is that the sudden appearance of a tiny black hole is going to going to misdirect people from my little con.Oh, any ideas on how I can create the black hole? I've decided ultracapacitors are a good starting point, and some of those cool rare-earth magnets, and some sort of crystal... Oh, and I'll call it a "green hole" for marketing purposes, of course.

content: Hi group,Here are some measurements that I made.The inductor used for all these tests is a TDK VLF50122R2M2R0 (Digikey 445-4232-6-nd)This has a DCR of 83m Ohm.No Load Input CurrentThe Iq increases with lower Vin. The no load input power is around 27 uW.At 20uA this would discharge a 2Ahr AA battery in 100K Hours (11 years). The battery self-discharge is probably in the same order of magnitude.Efficiency and Power Loss at Iout=50mAThis graph shows the efficiency and power loss at a moderate load of 50mA.Efficiency at 250mAThis graph shows the measured efficiency at 250mA.Battery ESR MeasurementI measured a Duracell Procell AA battery using a transient load. The load is configured to step the current from 100 to 200mA current. The battery voltage was measured with a scope directly across the battery terminalsThe ESR = dv/di= 0.0217/0.1 =0.217 Ohms (This is a fresh battery)I repeated the test at 500 Hz to look for any high frequency effects. The scope shows the battery is very resistive.Transient Load Testing of the Boost circuitI applied the transient load test to the boost circuit. At 100 to 200mA the output is dominated by the voltage ripple. The ripple is moderate, because the IC is operating in burst mode to reduce losses at light currents.At higher currents, 400 to 500 mA, the IC operates in the continuous mode and the transient response is revealed:The boost circuit does a good job of shielding the load from the ESR of the battery, but the load still has to deal with the transient response of the boost supply.Switch Node WaveformThis picture shows the switch node. You can see the top MOSFET being turned on, this is typical of a synchronous boost supply.Thermal ImageThe Lab is around 20oC.The boost converter was running for an hour with Vin=1.2 and Iout=250 mA.The IC was at 27 and the 24.8CRegards,Jay_Diddy_B

This should give an idea of how discharged a cell could be and still work with a "bursty" load.

The current is 200mA measured with a Tektronix TCP202 dc current probe:Same setup without using the flash:And the current drawn during start up:If I zoom into the peak, I see this:The batteriser needs to be able supply about 1A of peak current if used in this camera.So now I know what the peak current looks like I can use an electronic load.This picture shows the battery terminal (input), blue trace, using the boost circuit:Without the boost circuit, the battery terminal voltage looks like this:The battery voltage drop less without the boost circuit than with.Note:Some the components I am using are too big to fit in the batteriser clip.FAILfor high current devices like digital cameras.Regards,Jay_Diddy_B

Batteries never drain at the same rate and the set kick in voltage will vary as well. That will make for some oscillations unless the batterizers can talk to each other?

content: The PCB for the BUTTeRUSEr is almost ready, just a few hours of work on it, and I'll update the repository, and I plan to do a pcb run from it, then at the same time in fact I will do a BUTTaNOYEr too, but I think, I will create a specific thread from both project, it's not nice to steal this thread for my project

content: - BUTTeRUSEr is funny. It has funny means, with gay ones too.- BUTTaRuser?- BUTTnoisier?- BUTTarousal?- FartRiser for the one with sound?What's wrong with butt probes? I'm sure many people like them! There's stuff about giving voltages to prostate, I did read here that's a very annoying way to get sperm from animals.Who knows? Maybe we should try to experiment it, just for scientific reasons

content: Has anyone looked at Batteriser's patents? The circuit board at revision 4.2 surely violates their patents, right?How does the USA patent system work now that AIA was passed? Is there a review time where people can review and make comments to invalidate obvious or fraudulent patents? They were talking about adopting a system like that ten years back.
