Re: 1+1=3: Planning and creation of a 2WD fast electric bike

Thanks, interesting stuff. I have bought ferrofluid from ebay long ago and made my own from VCR tapes, neither would work for this application, thats why I asked and learned about that product. Looks ok for low rpm motors, I was interested in higher rpm motors like my quads have (4s to 6s) and 2400~...

Re: 1+1=3: Planning and creation of a 2WD fast electric bike

You mentioned a plan to increase the motor phase wires. I wouldnt expect and increase in performance, or improved voltage drop. However put in the fattest wire that will fit the passageway between the inside and outside of the motor. Once outside, make the wire even fatter. I am guessing longer pha...

Re: When Windows 7 is dead in 2020 what OS will you migrate to??

I been playing a few games lately on my xeon E5-2689/32gb/rx580-8gb, this cpu is laughing at these games, mostly around 30~40% use, my video card is 100% used, but no lag or stuttering, seems these days its mostly about the video card is the limiting factor. I am truly a beleiver of the YT video, 8c...

Re: When Windows 7 is dead in 2020 what OS will you migrate to??

I want to record live tv OTA antenna (PVR), I have a HDhomerun quatro (4ch tuner), a couple different android based TV box's. I am not sure how to get this going? Do I need a NAS drive? (or just a usb drive plugged into the android box) Links? TIA. quad tunner https://www.silicondust.com/product/hdh...

Re: Capacity Mapping (Optimal Charge-Discharge Voltages)

"most" packs i deal with in rc have zero bms circuit, only balance leads, I can see most packs for ebikes probably do (they rarely use a good balance charger), i should of been more specific. :D It was a painful costly experience with HvLiPo's. For me, a 70 cent lipo alarm is all I add to any DYI pa...

Re: Capacity Mapping (Optimal Charge-Discharge Voltages)

I recalled with Y axis in mWH, there is a little more peaks/valleys. 18650 capacity per voltage region -B.jpg The reason i asked about "best" storage voltage is I tried the Hyperion G7 (6S 2800) packs, what a total disaster storing them at the industry standard 3.85V (7 different MFG chargers i have...

Re: Capacity Mapping (Optimal Charge-Discharge Voltages)

You'd get a more accurate graph if you charged/discharged at a lower rate and measured more often. In your first charging graph where the voltage goes up from 3 to 3.5 in 400mah and one measurement, the "line" between those data points appears more like an exponential curve. Yea, I should not of ev...

Re: When Windows 7 is dead in 2020 what OS will you migrate to??

@ Acido, I am assuming your going to be gaming with the OS, I would think it would give better benchmark results, have you tried and compared the two, if there is a difference? Now that Win7 is "dead", have you guys heard any hacking that has been done on Win7, I have not? FYI, after many attempts o...

Update: the second graph is discharge at 1A to each datapoint on a 18650 single cell. 18650 capacity per voltage region.jpg It does have a couple valleys, but not really like some of the graphs posted earlier in the thread. Is it my testing method? I am using a GT1000 charger (resolution is good to ...

Most of DA’s capacity mapping is done whilst DISCHARGING rather than charging.
Good to know, most discharge curves I see are relativity flat (for most of the capacity), so I am even more curious why his graphs are all bumpy. I will try and report back, thanks.

Re: Capacity Mapping (Optimal Charge-Discharge Voltages)

I came across this thread by accident, neat testing. I had no idea, the peak and valleys (capacity sections) were there in the batteries that is shown in your graphs. I might try this on a 18650 and LiPo. I have a couple changers i could use (306b, gt1000, isdt-Q6+ and maybe a couple others) or I mi...

If I am not mistaken, the M.2 would use up some pci-e lanes, so an issue on micro mobo's if you require them lanes. I did some homework on the 2011 chinese MB's, and this came up at the top on the russian site (https://xeon-e5450.ru/) and one YT'er, it is true 4ch memory and has the 4 pcie lanes to...

Looks like passmark has changed from v9 testing to v10 (whatever that means), so the same processor on v10 is about 20% to 30% less rating than v9 results, will update again, with more info.

I got my second Zeon, I ordered a x5675 and they shipped x5670, doh! It was just under $19 shipped, and 24 days from order to my door in US.
Instead of 3.07ghz, its 2.93ghz, passmark 7960 and I got 7794 (from the web).
I hope to get to replacing the 11yo i7-920 tonight, will report back.

Figures, it ran for 5 hours looping passmark last night on stock freq (3.3ghz) without ever bsod.
I think I am going to try a better/harder cpu test, like prime95 or any suggestions?
