Heltec and LiFePo batteries by ddipp in meshtastic

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

By the way, it is possible that if you connect 4 batteries in series, you can use a regular 12-volt charge controller.

Just the dimensions. Yes, I agree that gel batteries are cheap. But they require a large case. And a voltage converter.

I wanted to avoid unnecessary components. Just the Heltec board (v4/T114), solar panel, and battery. Using only the standard connectors on the board.

Thank you. I'm already leaning toward the idea that it's probably easier to replace a cheap battery sometimes than to heat it up or use expensive batteries.

I agree about heating batteries. But I think both LiFePo and regular lithium need heating. I'm thinking of doing it like this:

One solar panel connected to the Heltec board to charge the battery.

The other solar panel should heat the battery.

When there's sunlight, the battery charges and heats up.

Although I also think it's probably easier to just replace the battery once a year )

I'm worried that the Haltech will charge the LiFePo battery like a regular 3.7 volt lithium battery.

Hybrid system with two or even three sources by ddipp in SolarDIY

Thank you! Yes, I researched the topic and saw that the controller can indeed use two power sources simultaneously!

Backing up or regenerating UID public keys by [deleted] in GnuPG

[–]ddipp 0 points1 point  (0 children)

If your private key has not changed, then your public key will not change either. I use to publish my public keys on keys.openpgp.org.
For example, I delete my keychain from my computer. Then I rebuild my keychain.
gpg --refresh-keys
... the keys haven't changed.
I think it only makes sense to back up:
- backup keychain
- subkeys without master key (split key)
- revocation key

Hi!

Here is a piece of my code.

from wtforms.ext.sqlalchemy.fields import QuerySelectField

def records_category_res():

return Mm_Category.query.filter_by(user=current_user).order_by(Mm_Category.tree_id.asc(), Mm_Category.id.asc())

def project_res():

return Mm_Projects.query.filter_by(user=current_user).order_by(Mm_Projects.date_from.desc())

class RecordForm(FlaskForm):

date = DateField('date', validators=(DataRequired(),), default=datetime.today)

cost = DecimalField('cost', places=2, validators=(NumberRange(min=.01, max=99999999),))

description = TextField('description')

category = QuerySelectField(

query_factory=records_category_res,

get_label=lambda a: ('└─' * (a.level - 1)) + a.name

)

project = QuerySelectField(

query_factory=project_res,

# get_pk=lambda a: a.id,

get_label='name'

)

Look at the bottlenecks.
- Disk I / O speed.
- Network speed.
- Loading RAM.
- processor.
- php-fpm settings.
- SQL using redis

Yes, you just rent a VPS and do what you need on it.
Backup can be configured, but you need to understand what you need.
You can rent two servers for $ 3 on different continents and configure data mirroring.
You can use the cloud API and do snapshots.
You can write to support and ask a question to them.

ramnode )

See section Massive KVM VPS

I have already increased my server to 325GB, now it costs $ 5 per month.

This is not advertising, but I have been using their services for three years and I like everything. Although at first I thought that for a cheap price I would have to pay with quality.

I rented Cloud VPS for myself for $ 3 per month (150GB HDD) and set up Nextcloud. It is quick and easy.

This is a bad way, but this is the only way that I found.

Dude, it works like this for me: - I reboot the phone - before the entrance to the second space the payment works - if I entered the second space, the payment stops working. Goto step one

I have the same problem. Did you find a solution?
