Yo dawg I heard you like games so we put a game in your game so you can play while you play.

Rolive, 1 year ago to science_memes in Listen, Susan. It's a valid theory, just look at the damn thing.

Flat earth wasn’t silly enough?

I really should replay that game.

Rolive, 1 year ago to asklemmy in What are some companies that deserve to be boycotted to death?

Wish I could. I use linux whenever possible but gaming, hdr and some drm features won’t work on Linux any time soon.

Rolive, 1 year ago to asklemmy in Tech workers - what did your IT Security team do that made your life hell and had no practical benefit?

Some corporate BS screen lock application that replaces the built in Windows feature. It would take several minutes to log in because of that.

Fortunately you can kill the process with taskmanager and prevent the screen from locking entirely. Lol.

I’ll drink to that.

So Mint is Ubuntu based right? If Ubuntu screws up even more doesn’t that affect Mint as well?

Rolive, 1 year ago (edited 1 year ago) to electronics in What project are you currently working on?

An MPPT solar charge controller using Arduino as well as a homemade Li-Ion battery. Also an 18650 battery tester. So 3 projects simultaneously because they’re closely related.

I’m using a CC CV boost converter to convert solar energy to the voltage for a 7s Li-Ion battery. The arduino reads voltage and current and will try to adjust the CC value to obtain an optimal wattage. I have removed the CC potentiometer and replaced that with an Arduino PWM pin with voltage divider that sets the corresponding current limit. This way a relation between CC pwm duty cycle and solar output can be set.

DIY Li-Ion battery goes hand in hand with the solar project. I’m making a home battery out of salvaged laptop batteries. That requires a battery tester as well which I’m also making myself. The battery tester works by charging a battery with a TP4056 module and discharging as soon as it’s fully charged over a resistor while monitoring voltage/current over time. This happens 16x in parallel using multiplexers so 16 batteries can be tested simultaneously.

I’m also taking safety very seriously so all batteries are equipped with both thermal fuses and current fuses. That involves 3D modelling battery holders, printing them, spot welding/soldering etc. As well as an additional monitoring system on top of a commercial BMS so that the battery status can be monitored remotely. I intend to have a smoke detector, thermostats and an emergency cutoff switch controlled by that second BMS.

Once everything works to a somewhat satisfying degree I intend to post the projects in more detail.

Every project tends to explode in scope in terms of what it all requires so I’m not making as much progress as I want but it has been very educational.

Rolive, 1 year ago to askelectronics in How to get rid of swollen laptop battery?

Whatever you do, keep it away from anything flammable or near any living environment.

If electronics stores are not willing to help you could try the fire brigade. Call them on the non emergency number. They can advise you much better.

Rolive, 1 year ago to askelectronics in Soldering Iron Tips Stop Working/Melting Solder

Those wet solder sponges cause a thermal shock every time you wipe the tip. I recommend using brass windings instead. They also won’t completely wipe the solder off the tip either.

You always want a small layer of solder on your tip at all times to prevent it from oxidising. Oxidation means bad heat transfer causing soldering to be much more difficult. Also store it with a small blob of solder on it.

You should avoid scraping or sanding the oxidation of the tip. There is a small layer of silver that won’t oxidise so quickly but below that is normal iron. Not sure if that applied to cheaper Chinese irons but it’s better not to learn bad habits. Once you remove the silver layer you’ll get oxidation much more quickly and you’ll have to keep scraping until the tip is gone.

You can remove oxidation with the brass windings much more easily than with a sponge. When you apply solder with flux the rest of the oxidation should come off fairly quickly.

Buying a cheap model to practice is a great idea, when you are used to that you can look into a better iron. I’ve been very happy with the TS100 but the Pinecil is the newer model apparently.
