  1. Hello, Would you mind posting a screenshot of Device Monitor when taking a puff, or posting a recording CSV of the puff? I'd be interested to see what Power is doing, and what the Live Ohms are. Make sure to check those. You can click on the trace as it scrolls to get the values at a particular moment in time. Your screenshot also shows Cold Ohms as 0, which indicates it hasn't fired yet I assume. What do you measure for Cold Ohms for the coil? I'm curious to see what limit you are running into. Thanks! James
  2. Here's a question. If you pull up your puffs in ECigStats, is it saying "dry coil"? What do you get as your Cold Ohms and Live Ohms near the end of your puff? I'm wondering if Live Ohms is 18% above Cold Ohms (dry coil) or 24% above Cold Ohms (wet coil)? It determines wet coil by how much energy can go into it in a quick amount of time. If a juice is particularly bad at wicking, that could be the cause. I think John tested with 50/50 VG/PG, but I'm not sure. I will ask him next time I talk with him. If a juice has a ton of flavoring, enough to meaningfully affect the thermodynamics, I wonder if that could cause it. Let me know about the Cold Ohms and Live Ohms. We have a ton of settings on these devices, so none of this is hopeless or set in stone. Equivalent Ohms is something of a practical compromise. People tend to associate the vape they get with a Kanthal coil of a particular resistance. But what they are really asking for is not an electrical resistance, but the thermodynamic properties associated with that electrical resistance. The resistance of a Stainless coil, for the *same surface area and other thermodynamic properties*, is different from a Kanthal coil. Thermodynamics doesn't care at all about electrical properties. So, if manufactured correctly, a Stainless coil of "Equivalent Ohms" is meant to match the *thermodynamic properties* of a Kanthal coil of a particular resistance. Now, one could do it another way, but otherwise "I want a vape similar to my 0.6 Ohm Kanthal coil, but with temperature protections" becomes a rather confusing question to answer. Hope this helps. God bless. James P.S. There are other practical compromises. See the "True RMS Power Mode" checkbox? That's a fun one. If you want your watts setting to match your expectation on every PWM pod device we saw, keep it unchecked. This is "PWM Power Mode". If you want your watts setting to match thermodynamics (and non-PWM devices), check that checkbox! This is "True RMS Power Mode". (Actually, we did do better than other PWM pod devices when in "PWM Power Mode". See "Simulated Battery Voltage"? We make the true thermodynamic watts setpoint stable with battery voltage and battery voltage drop. The way most devices do it, this isn't true. Read on if you care about the math.) It turns out all of the PWM pod devices determine their duty by P=Vpod^2/R, so Vpod=sqrt(P*R), from which they conclude PWM=Vpod/Vbat=sqrt(P*R)/Vbat. A multimeter will back them up in this. (Mostly. There's also a huge battery voltage drop when firing on PWM devices.) The voltage is correct! Unfortunately, this is wrong. A multimeter will average the voltage over its sampling period. A PWM device is actually on/off. So the *real* power on a PWM device, when fully on, is P=Vbat^2/R, because it is connecting the battery to the coil. So, at a particular PWM duty cycle (0-1), you get P=(Vbat^2/R)*PWM, or PWM=P*R/Vbat^2. What's humorous about this is, when you measure with a multimeter, you're going to see the *averaged* voltage Vpod=PWM*Vbat=Psetting*R/Vbat. You're going to say "Let's use Ohm's Law", Pcalculated=V^2/R, and apply it to that averaged voltage, to get Pcalculated=Psetting^2*R^2/(Vbat^2*R)=Psetting*(Psetting*R/Vbat^2). See? The multimeter will tell you that it's wrong, when it's thermodynamically correct. You can't average voltage and then do that calculation on a PWM device. The factor by which it's off is how wrong the other calculation is. What you can see from the equation is that the way other PWM pod devices calculate wattage is not only incorrect, but the real wattage will change as the battery drains, and in a way that is different depending on the coil resistance. Fun! This is why the Oxva Pro 2 DNA has a "PWM Power Mode" Simulated Battery Voltage setting. We did better than the other devices by (1) matching the wattage you'd find on other PWM pod devices, *at near full battery*, while (2) using *correct* power control to make that stable over resistance and battery level. We left both options in. We knew for "PWM Power Mode" that most users of pod devices would be surprised if, even if entirely correct, the wattage level they set felt different than other devices. We also knew for "True RMS Power Mode" that we have some folks who can appreciate an accurate and correct vape.
  3. Try going to Tools -> Diagnostics -> Reboot Device -> Hard Reboot. Does this fix it? Thanks!
  4. I've posted SP67. If your Oxva Pro 2 DNA has a prerelease firmware, it will now offer to upgrade to the release firmware and settings.
  5. I've posted SP67 for Linux, which adds support for Oxva Pro 2 DNA.
  6. EScribe Suite 2.0 SP67 For US-based customers (Windows): https://downloads.evolvapor.com/SetupEScribe2_SP67_US_ServicePack.exe For US-based customers (Mac): https://downloads.evolvapor.com/SetupEScribe2_SP67_US.pkg For international customers (Windows): https://downloads.evolvapor.com/SetupEScribe2_SP67_INT_ServicePack.exe For international customers (Mac): https://downloads.evolvapor.com/SetupEScribe2_SP67_INT.pkg If you would like the Oxva-specific version, https://downloads.evolvapor.com/SetupEScribe2_SP67_OXVA.exe For customers using Linux, see the beta thread. --- Oxva Pro 2 DNA --- If you are running a prerelease version, SP67 will now suggest upgrading to release version firmware and settings. --- EScribe Suite --- Bug fixes.
  7. I've posted a test version of EScribe, SP66: It adds support for the Oxva Pro 2 DNA, as well as some pre-release experimental devices. Let me know if you run into any bugs with it! Thanks! God bless. James
  8. EScribe Suite 2.0 SP66 For US-based customers (Windows): https://downloads.evolvapor.com/SetupEScribe2_SP66_US_ServicePack.exe For international customers (Windows): https://downloads.evolvapor.com/SetupEScribe2_SP66_INT_ServicePack.exe If you would like the Oxva-specific version, https://downloads.evolvapor.com/SetupEScribe2_SP66_OXVA.exe --- Oxva Pro 2 DNA --- Added support for this pod device. It has power control, Replay, customizable color schemes, support for 11 languages, and ECigStats support. --- Experimental Prelease Devices --- Test if you're interested. DNA 55 Color: This has customizations appropriate for pod devices, such as automatically distinguishing between different atomizers by resistance ranges -- see Mod->Atomizers. There's support for power control and Replay. Like a Color DNA, the user interface can be edited with Theme Designer. The Theme Designer support is a work in progress but does have some new features. DNA 80 Color Pod: This has customizations appropriate for pod devices, such as automatically distinguishing between different atomizers by resistance ranges -- see Mod->Atomizers. (You can switch between Color and Color Pod by applying firmware.) --- EScribe Suite --- Production Utility has been upgraded to support scripting and higher throughput operation. Bug fixes.
  9. Nice! I'm glad to hear EScribe works with screen readers as well.
  10. (removed: Wayneo and Roxii already made a theme) NoOptionsTheme.ecigtheme
  11. Aha. I accidentally left Air Flow out of the newest public version. I had it marked as 'for test versions'. It will be fixed in the next update.
