Sunken USB Type C breakout 🔌🛠️🧩

Folks love our standard USB Type C breakout (https://www.adafruit.com/search?q=usb+type+c+breakout) - and we recently got a request to carry a 'sunken' Type C breakout - what's that mean? It looks like this! instead of sitting above the PCB the connector sits in the midline for a svelte look. this connector got our pick because it has four burly THM tabs to keep the connector from cracking at the contact pads.

Honey, I Shrunk the Kids (1989)

[dumbgirlgamedev]

So I've been busy...

It took about 2 and a half hours and was nerve wracking for every step but I modded my iPod classic and turned it into a very personal and special super nugget. It has 128gb of flash storage on it and it is so much lighter and faster than it was. I absolutely adore it and I am so happy with it! Take a look!

I do want to give special thanks to the following amazing people, without them this project wouldn't have happened:

IFixIt for the tools and the guide; their resources for replacing the iPod's click wheel was invaluable:

Elite Obsolete Electronics for the parts, this project would have been 100 times harder without them, check them out if you need replacement iPod parts:

DankPods for starting this whole project, his content got me into proper music listening and physically owning music again and his passion made me want to get into this hobby in the first place. Plus his guide on repairing old iPods were a major help! Please check out his channel if you're interested in music, headphones, and weird audio players:

Converting a battery backup to Lithium because I hate myself

I've got a whole bunch of battery backups in my home, one on each computer, and a big one in my server rack in the basement. I've also got a few out "in the wild" at some of my family's places. They're great, where I live in the northeast US, the power grid is stable enough that most outages are only minutes long, and these backups (technically called a UPS - Uninterrupted Power Supply) do a great job keeping computers running through them.

My issue is the batteries. They all run on lead acid batteries, aka the same kind that's in your car, and they dont last long in this kind of environment, I'm lucky if I get 3 years out of one. On top of that, their battery life detection is terrible, It's about a 50/50 shot whether I get a warning about a dead battery pack before the next power outage takes it down without warning. Keeping track of that with just one or two is annoying, let alone 10 of them!

Lithium UPS's exist, and theoretically last many years longer, but they are many times more expensive than a normal backup. I'd like to not spend new-car money replacing a dozen UPS units, so I did some math instead.

I have a husk of a ups (no battery), and I tested it out: the open circuit voltage on the battery cable is 27.6 volts, which just happens to be almost the exact voltage needed to float charge a series of 8 Lithium-iron-phosphate (LiFePo4) batteries!

Why is that exciting? Usually when you think of lithium batteries, you think of lithium-ion (also can be called lithium-polymer) batteries. These are the batteries in your laptop and phone... And also Tesla cars. They hold more energy than a LiFePo4 battery, but are very sensitive to temperature, over and under-voltage, over-charging, and over-current conditions. Abuse them too hard, and they swell up and pop! That's why Teslas seem to catch fire more often than other cars: most other companies gave up range for a battery chemistry that isn't a ticking time bomb, like LiFePo4.

These LiFePo4 batteries can take a beating compared to Li-ion ones. Most importantly, they can be "float" charged, that is, left on the charger 24/7, without worrying about overcharging it and blowing caustic smoke everywhere. This is critical, because I'm attempting a direct drop-in swap for the old lead battery in this UPS, because float charging a lead battery is basically a requirement, and doing that to a Li-ion battery is asking for a fire!

Using a Li-ion pack would require a custom charging circuit, as the UPS's 27.6V is not correct for any configuration of Li-ion, and would either under charge the pack, losing me 50% of my capacity, or overcharge it, and make it explode. It would also have to stop the batteries from being float charged, again to keep the battery from exploding, while fooling the UPS into thinking a battery is still attached so it doesn't beep at me all the time, and my head is spinning just thinking about how that would work. Much easier to give up capacity for a simpler, and more robust battery.

This UPS can deliver 900 watts of power on battery, that equates to roughly 30 amps of current from the 27.6V battery pack. Adding a safety factor, I bought a BMS (Battery Management System) rated to 50 amps. A BMS is essential, as it offers extra protection against short circuits, over and under-charging and temperature cutoff. Also cell balancing, which keeps all the cells at the same level of charge during use (if they go out of sync-that's bad, is all I'll say for now). The batteries are rated for 120 amps continuous draw, so I am well under the limit where the cells would self-immolate.

With all that said, here's the guts:

Looking close, you might see that I had to cut some plastic out to make it all fit. That's an error on my part-I didn't measure right. If I make more, I'll definately be using a smaller cell, so it will be a proper "drop in" mod. Lots of drilling, cutting, and filing to make this all fit!

It took several hours to link up the cells, terminate the balancing wires (the small red spindly ones), and and stuff them in the battery box. That's a LOT longer than I was hoping it would take, but the on-the fly mods took a lot of time. but eventually, it all fit in, and I was able to test it:

It works! I unplugged it from the wall, and it stayed on! For now, I am in full helicopter parent mode, since I don't want to deal with a lithium fire, even though my math checks out and the UPS should never get the the point that these cells are ever "abused". I only leave it on when I'm in the room, and when I leave, I unplug from the wall, and remove the red lead from the battery, so no charge enters or leaves while I'm not there to watch it.

In theory, the only issue with this retrofit will be a useless runtime meter. The "minutes of runtime" meter is measuring the voltage of the battery as it discharges to estimate how much longer it will last, and the voltage drop over time is different for lithium and lead, so the meter won't be measuring accurately. Once I'm confident it won't explode randomly, I will likely install it permanently somewhere in one of my compters.

Wish me luck!

DIY Basics

-Goth DIY Tutorials Number 1 (Part 1)- Hi there, I decided to start a little DIY series! I’m not the most professional at anything lol but I’ve been doing DIY and crafts my entire life and been part of the goth subculture for 10+ years. I’ve seen a lot of baby bats and people inexperienced in crafts online saying they don’t know how to DIY thrift store clothing to be goth so I’m here to help! I believe DIY is super important to the goth subculture and should be easy and accessible, and if I can stop anyone from buying big fast fashion brands I’ve done my job.

For the first post of this series I thought I’d link some sources for people new to DIY or looking for some easy projects to do yourself (projects will be in part 2)🖤This will help you find a starting point if the idea of DIY is overwhelming.

None of these links are mine! I will be posting my own tutorials as part of this series though:)

Some of the most basic starting points for goth DIY are using fishnet tights as a top (just cut a hole in the crotch and cut off the feet), putting safety pins in everything, adding holes to clothes, and adding pins and patches. I like to make my own patches, either by free handing or stenciling, which I linked a tutorial for in this post.

Helpful tools to have:

(I don’t agree with buying from aliexpress but their other sources are great!)

Sewing Tips for Beginners:

T-Shirt Design Methods:

This is just s few ways to weave t-shirts, there are a ton of different ways to do it and YouTube has some great tutorials, especially on Angela Benedict's channel

RIT Dye Tutorial:

Patches:

Sewing them:

Stenciling them:
