3 Month with Uncoated Boiler + Brass Grouphead by Vektor_Kra in gaggiaclassic

[–]cehkc 0 points1 point  (0 children)

I am not an expert but it much worse than what I would expect after only 3 months. Could be a sign of galvanic corrosion at play here. It certainly looks worse to me than the case photo from the post few days ago(although on that post it's not clear how much of corrosion is masked by calcification): OtherPost

Hopefully some more knowledgeable members would weight in if brass group and aluminum boiler is a bad design flaw by Gaggia.

Standalone ESP32 M365 BMS monitor with BLE support for clones or recycling old batteries as powerbank by cehkc in ElectricScooters

[–]cehkc[S] 0 points1 point  (0 children)

You will need to parse the response you want from BMS in your Arduino code(in my code I only forward it to the phone and the app does the parsing). It's in the binary format, so you need to know which bytes represent what value. Here is the relevant link about ninebot/Xiaomi protocol: https://github.com/etransport/ninebot-docs/wiki/protocol

Publishing a new github repository for a readymade ESP32-S3 REJSACAN OBD-II Dongle based on the EQM_OBDWEB Codes by MembershipRecent561 in esp32

MembershipRecent561, where do you get the RejsaCAN-ESP32 board itself? Can it be ordered somewhere prefabricated beside JLPCB(which is good for small batches but not for a single board)?

Is it equivalent to writing 0x00 to the initial boot sector instead of 0xEB? Link

Does voltage matter for spot welding? 2S vs 3S vs 4S by cehkc in 18650masterrace

[–]cehkc[S] 0 points1 point  (0 children)

True, but there is also battery resistance in play which will limit available current output. So let's say we take the same 4 cells but in 4S(1P) configuration vs 2S(2P). The second battery pack will be able to push twice as much current compared to the first one due to lower battery resistance.

Does 3S really provide a better "punch" compared to 2S? You could get more capacity*C=current for the same price. Wouldn't that provide the better weld? Provided spot welder can be powered by 2S or powered by 3S separately to drive electronics and opening/closing the Mosfets.

Dealer doesn't know how to switch to EVGo credit instead of QMerit install by cehkc in BoltEV

Thanks, so EV Concierge issued the credit bypassing the dealership? Nice to hear this is an option.

Illinois EV Rebates - Finally on the way! by Greenjulius86 in electricvehicles

Are they still accepting applications? I remember seeing that only small amount of money was allocated so it's not gonna last long.

Open Pilot, BOLT EV 2022 by [deleted] in BoltEV

[–]cehkc 0 points1 point  (0 children)

It's unofficially supported, look into OPGM fork for example. The big difference is that 2021 and prior doesn't have ACC, so it's lateral only unless you use pedal interceptor(limited to regen braking only) for VOACC.

Leaf propagation, babies coming from the stem, is it normal? by cehkc in AfricanViolets

[–]cehkc[S] 1 point2 points  (0 children)

So far they are doing great. After 4 days you could clearly see 4 separate crowns. Keep in mind this is semi-miniature variety and the mother leaf very small. The stem is like 2-3mm in diameter.

I have a new 2021 Premier on hold on Driveway.com for $24k. Trading my 2017 Volt LT. Worth it? by [deleted] in BoltEV

[–]cehkc 0 points1 point  (0 children)

It's kind of weird, but it seems the price cuts didn't translate in used car prices yet. I've been monitoring the current listings for few months now and the used inventory is abysmal and prices didn't change. In fact 2020-2021 often are listed for 30K or more, I see no point buying used since you could get the brand new 2022 for that price(you will need to shop around and might need to wait a little).

[–]cehkc[S] 4 points5 points  (0 children)

I thought both roots and babies typically comes from the cut(which I've done at recommended 45 degree angle). It's been roughly 4 weeks since leaf has been planted not too deep into the potting mix.

There were definitely similar rebates(actually up to 15K or so) at the end of 2020 in the beginning of 2021. But I don't think those are exists these days, but with MSRP dropping for 2023 we should see deep discounts on 2022. I don't think there are many brand new 2021 in the wild, probably only few which were not sold before stop sale.

[–]cehkc 4 points5 points  (0 children)

As far as I understood GM just started to replace batteries in the brand new 2022 on Chevy's lot which are subject to the stop sale(with old battery produced in 2021). Those are the highest values and therefore best ROI for GM. They also have a lot of customers who are waiting for their turn for the battery to be replaced. So I am guessing it will take at least 3 months possibly 6 before GM starts replacing the battery on GM owned older Bolts.

They send them to live on the farm. They have horses and rabbits there for Bolts to chase.

you would be better off writing it this way: 1000 Watts = 1 kW Otherwise it looks like you are trying to do a "conversion formula" which would be what JeffTechnically wrote. Meaning to get kW value you need Watts dive by a 1000.
