01:45 AM rue_mohr: 1Ah
01:59 AM rue_mohr: the ability to provide 1A for 1hr, if your able to deplete the battery to 0%
01:59 AM rue_mohr: which you cant
01:59 AM rue_mohr: lets say you can take 25% of the charge off a lithium ion
01:59 AM rue_mohr: then you have 1A for 15 minutes
01:59 AM rue_mohr: my circuit pulls 250mA
01:59 AM rue_mohr: so, I can expect 1hr of operation
01:59 AM rue_mohr: 15mins*4
06:04 AM rifraf: https://desire3d.com/images/public/shot8.jpg
06:07 AM rifraf: pumped up the vibe as well for you tom
07:11 AM Tom_L: save settings still doesn't
07:12 AM Tom_L: help is all good now
07:13 AM Tom_L: gotta run, will check the rest later
10:43 AM rue_mohr: rifraf, for debugging, can you show the fft results?
11:44 AM Tom_L: mine should get much better once i get the glass
11:44 AM Tom_L: at least that's my expectation
03:32 PM rifraf: rue_mohr i could, but that wat i been doing for a month
03:40 PM Tom_L: not gonna test anymore until the glass comes
03:40 PM Tom_L: will get more true results that way
03:42 PM rifraf: just to prove you don't need it i just did a test on a spice jar lid, sure more fraction but a perfect graph still
03:44 PM rifraf: friction, but that wat this is for, to be able to test different levels of friction etc
03:44 PM Tom_L: trying to balance the top on the flat phone was causing the spikes i'm afraid
03:44 PM Tom_L: it kept wandering and i couldn't get it perfectly level
03:45 PM Tom_L: ever so gently moving but still
03:46 PM rifraf: yep, a rim on the edge helps alot, can barely get 30 seconds on this little plastic lid, but still see a smooth decline in speed
03:47 PM Tom_L: also trying to figure a way to get some sort of knurl on the handle
03:47 PM Tom_L: may mill some V around it using the rotary axis
03:48 PM Tom_L: i don't mind waiting a day
03:48 PM rifraf: coarse sandpaper is enough for some grip
03:48 PM Tom_L: i know
03:49 PM Tom_L: i have 6000 down to 36 grit i can select from
03:50 PM Tom_L: may get the boy to make another one a bit thinner
03:50 PM rifraf: a few swipe with 36 will help
03:50 PM Tom_L: yeah
03:51 PM Tom_L: or scrape it with the edge of a file
03:52 PM rifraf: drop it on the floor, chew on it for a while, yep would be a few ways
05:51 PM Tom_L: any new mods?
08:52 PM rue_mohr: ok, well, I got one thing off my list
08:52 PM rue_mohr: I built a table like thing to stand over the dishwasher
08:52 PM rue_mohr: so that disposed of a pile of materials I been collecting for it

09:34 PM aandrew: https://github.com/ericjenott/Evertop
09:34 PM aandrew: this seems up your alley
09:35 PM aandrew: swap out the 8086 for 8051 maybe
09:35 PM rue_mohr: cute
09:35 PM rue_mohr: heh
09:35 PM rue_mohr: I'm not TOO much an 8051 fan
09:35 PM rue_mohr: z80 for me
09:36 PM rue_mohr: even tho the 6502 cycle efficiency is amazing
09:36 PM rue_mohr: _I NEED REGISTERS!_
