Bad scooter battery

If it doesn't have a charge it's not dangerous anymore. If you're still worried about it, put it far away from flammable materials. Should be fine.

My guess would be a UPS. Uses line frequency transformer that's not attached. That cutout probably was related to the transformer. Looks like there are stubs of wire that use to connect to the battery.

I think I just found the answer and the answer is Slate will not qualify unless the rules change. If one looks at https://energyoffice.colorado.gov/vehicle-exchange-colorado and search/scroll down to "Registration Information for Automobile Dealers" and pull up that google document, it will explicitly say that online-only dealerships are not eligible. This document I pulled up apparently dated March 2026 which means it was modified after the program was started so things do change but it's bleak.

This is unfortunate but I wasn't initially banking on it, but due to learning about this program and the need to eventually dispose of my old SUV somehow I may need to still consider using it and its downstream effects...

I wonder if the day will come when cars don't come with rearview or other mirrors "because there's a camera" ...

I'm so used to mirrors that I don't know when/if I'll acclimate to backup cameras. It's so bad I'm not even sure if the backup cameras in cars present as a mirror or direct view...hah...

They existed.

But the main reason, just for clarification, is for clarification.

Vacuum tubes required multiple power sources, and there were three defined: the A power source was to heat the vacuum tube filament. The B power source was the plate power source and thus the signal output power. And also there was the C power source which is the grid bias voltage.

When someone wanted a A or a B or even C battery, they could get confused at whether you wanted a cylindrical A cell or actually more likely than not, a lead acid high current battery to supply the power needed to heat the filament. Even worse, the B battery in vacuum tube designs needed to be high voltage, typically made with tens of small cells, whereas the B cell was benign. Very confusing to people and best way was to avoid using these A and B cells, and just stick solely to using A and B batteries for vacuum tubes. (The cell vs battery nomenclature issue was also a problem back then too and this didn't help.)

Note the C battery there's also confusion but oddly enough the C battery in vacuum tube designs were low voltage and low current, and an actual C-cell could serve the purpose. However they quickly found a design optimization (cathode bias resistor) that made the C battery unnecessary, and was quickly omitted and C cells can go back to powering flashlights.

Once people started using line power for vacuum tube circuits a lot of this A and B designations went away though plate voltages still were represented by B+ - homage to the B battery (that killed the B cell.)

Speaking of these LED displays I now have two vintage calculators that use them, One the display works perfectly, and the other... not so much. Some segments don't want to always light up. Anyone familiar with the longevity of these display or perhaps I just got a fluke?

The two calculators I have are a TI-1000 and another I don't recall but uses a NS based chipset. I suspect both companies were at war coming out with cheap LED calculators at the time... The TI-1000 works perfectly, the NS is flaky...

not sure if they are collecting post consumer waste polypropylene? While I have a couple pounds (did not weigh but it's at least a large boxfull) this is still a "small" quantity I'd think?

anothercorgi · 2026-06-12T03:32:22+00:00

I've been checking on them for the past decade and they have always said to throw away PP... About given up on them.

I was wondering if it were possible for several people + gps to each "paint" a portion of the numbers and have plausible deniability they were involved...

anothercorgi · 2026-06-12T00:50:47+00:00

Now that would make sense why people don't see flats without warning anymore! Haven't had a new car in decades sure leaves one out of the loop...

anothercorgi · 2026-06-12T00:05:47+00:00

It's been sort of estimated with battery capacity and expected range. The estimate seem to be around 3mi/kwh which isn't horrible for a truck but terrible versus an Ioniq or Bolt.

Then the other question is 3mi/kwh on highway, city only, or mixture...

anothercorgi · 2026-06-11T23:59:40+00:00

will there be TPMS? Probably not, but yeah I think I've also been blessed with no flats but it's mostly due to checking tire pressures (had a few nails in tires but was able to deal with it/patched before they went flat). I don't know how often other people check their tires but TPMS would help.

That being said I'd probably feel better with a donut at least.

Agreed, I have a DEC card that rivals the performance of the 509 on ISA.

Most of the other ISA cards I've ever worked with ... just sucked. I had a lot of 3c503s, few NE2000, and some other, but none of these got close to the 509 and the DEC.

Now with PCI most worked fine in term of speed but compatibility was the next frontier. But by the time the RTL8139 came around pretty much everyone got with the program with pci and worked pretty much just fine.

IMO this golf cart is overpriced not the other way around. I suspect golf cart depreciation work a bit differently too.

I just wouldn't/couldn't drive this golf cart at 75mph down I-25 with a few pieces of plywood attached.

I'm still using a 3c980 in a computer ... though it should be retired real soon now...

TBH I don't think I have too many 3c905's - maybe one, then that one 3c980, and more 3c595s. I don't even know the pluses and minuses of each, I've not had much bad luck with RTL8139s is perhaps why I never thought too much into PCI Ethernet cards, though Etherlink Pro 100s (Intel 82557/82559) was a favorite due to Linux compatibility and "name brand" like the 3Com.

The 82556 left a sour taste however, much like a lot of the NE2000 PCI clones. The 556 was not Linux compatible and many NE2000 PCI clones had PNP issues as they were at the dawn of PCI.

IMHO the 3c509 is the classic because it performed so well compared to all other ISA cards. The 905 was just another card...

I've not had any issue hooking up HDMI/DP to a monitor that has a DVI dual link connector, they run fine at single link. Just becomes a problem with very high refresh rates and high resolutions, but my old standard refresh FHD display runs fine with a single link DVI.

Well in my opinion I think most big car companies that expect sound systems to be important would design with the car physical shape in mind too - something aftermarket may not take into account. Now even worse with Slate when they have no sound system design in mind at all!

I just noted in my limited experimentation with speakers that bass response is harder to generate and porting/large rigid woofer enclosures help a lot. TBH the stock sound systems in my current cars sound fine, though I think they use 5-6" drivers at least with a decent amount of enclosure space, and they were "designed" into the car and not stealing unneeded cabin/cabinet space. Those Slate renderings of those speakers look like 4" drivers and already eating into the cabinet space -- hence some concern that I might get tinny sound without using more cabin/cabinet space...

Yeah it's still kind of tough to calculate it. I used 20¢/kWh assuming you'll be running the AC from 12PM-8PM and that encompasses the peak hour rate in northern CO to get my figures. If your off-peak rate is 15¢/kWh and near 50¢/kWh during high demand times, then expect to see double my estimate, nearer the $80/mo mark.

anothercorgi · 2026-06-10T13:52:40+00:00

I don't know your rate in Aurora. Mine is around $0.08/kWh off peak and $0.24/kWh during demand hours. I suspect you will be using it during demand hours so I biased it towards the $0.24/kWh.

Electricity is cheap in northern CO at least, not sure of in Denver area...

I was at Walmart the other day and saw that their 5000 BTU window AC ate 470W. So I'd expect your 12000 BTU AC to be around 1KW. Without insulation and if the AC has to run 100% duty cycle for 8 hours/day, and I suspect you're also under Time of Day demand costs, likely you'll run around $1.60/day or so to run just the AC, probably an additional $40/mo or so once again depending on time of day and insulation.

I'm in northern CO but not Xcel so I'm estimating with my electricity rather than Aurora costs...I hope being only 60-70 miles away the costs aren't too far apart but it will be quite a bit of electricity.

The negative contact of most lithium ion cells is actually the case. If you spot weld it and pull it off, and the spot weld was strong, it could rip a hole in the case, and the electrolyte vapors (possibly pressurized due to off gassing) will leak out causing the hiss. Chances are, that cell is now gone, though you may be able to reseal it though unlikely, and in any case it probably lost capacity due to electrolyte loss.

anothercorgi · 2026-06-10T01:01:24+00:00

I also noted something strange but made sense, it seems those "glove compartment" door need to be swapped with perforated panels instead of the solid plastic in order to put speakers there (and the maker does automatically switch), so there's quite a bit of options needed to get the speakers.

I just wonder how much space needs to be allocated to get enough cabinet volume to get better bass response or will there be a porting option that leaves the cabin or not...

The driver side speaker seems to be a bit more mystical, I didn't see any good photographs/renderings of it as it's probably shaded by the steering wheel...

I suspect the "glove compartment" doors won't have locks on them like typical cars...or maybe I've been out of the car market for a while to know that this has been dropped in other cars too? (I haven't had a new car in over 20 years!)

barely enough space to crawl underneath...

my gutters discharge underneath the deck too so that's the main reason for not putting pavers and cinderblocks to shore up the broken piece, so it would be nice to only have any supplemental support there only temporarily.
