Solar FLAG Lights

When I first launched Gallery 69 (a Free Little Art Gallery) I had this plan to add a light inside and have it solar powered. That never happened, but Dana offered me a set of battery powered holiday lights when winter came and I put it on the outside of the gallery so you could see it after 3:45pm when it started to get dark outside.

I would swap out a set of AA batteries every week or two depending on how long they would last and how often I would remember. I decided to revive the solar idea to power the lights. Here’s where I will add the disclaimer that I am terrible with calculating power requirements. Terrible. Too much maths for me. Anyway…

I had this Solar Panel from Brown Dog Gadgets which I wasn’t sure would work, but I had it so I figured I would start with that. I got these CN3065 Solar Charger Boards for cheap not expecting much. I also had my eye on an Adafruit solar charging board but they were out of stock, which seems to happen a lot with Adafruit. I grabbed a bunch of JST connectors as well.

For the battery I tore apart an old USB power bank. It was probably 10+ years old but it seemed to still work so hey, I’m cheap. (Don’t worry, I still have at least a dozen working power banks.) I did do a bit of testing to see how long it go before the voltage dropped too low. That testing is part of another project still in the works. Anyway…

Remember when I was making Rugged Box Silicone Gasket Seals? Well, I printed a rugged box with a hole in the top, hot glued the solar panel to it, ran the wires through the hole, and then sealed the hole and wires with hot glue. (Somehow I have no photo of that.)

Okay, I needed to power the lights, which worked with 3 AA batteries, so I used these Customizable Dummy Battery(s). Originally I was going to print three, wire them up, and use that… Along the way I only used one to make contact with the negative connector then used alligator clips for the rest of the connections. This is one of those “I’ll test this” sort of things that is now somehow permanent.

Yeah, so somehow I threw all that together and it works. It’s messy, but it works. At first I thought it was not working. I’d turn it on, check it the next day and it would be “dead” but it would turn on again. Then at some point Dana gave me the box the lights came in and I realized it lights up for 8 hours and then turns off for 16 hours. So it was working just fine. After that I left it alone to do its thing. I did make sure I turned it on at 3:30pm in December so it would be running when it got dark out. They should stay lit until 11:30pm.

When I wrote “A solar project that actually works…” above it was mostly a joke. I thought it didn’t work, but it did work. Meanwhile I struggled with another solar project at the same time, which I now also have working. I didn’t want to say “My First Solar Project” because as a kid I connected a solar panel to a small fan I got from American Science and Surplus and was amazed it worked. (That was probably around 1981 or so…)

So yeah, I did this back in December but wanted to wait a bit to make sure it would keep working… and since it’s been two months I think it’s good. The panel gets some really nice direct sunlight in the afternoon and even with a bunch of cloudy gray days it’s kept running quite well.

Rose Ferreira and NASA

I saw a post about Rose Ferreira being deleted from the NASA web site because the article about her was a story about “Women in STEM” and with the current (oppressive) administration trying to erase certain people I figured I would cite the original article here.

You can also see the article on Archive.org, but that too is under attack, so the more mirrors of important stories we have, the better.

NASA Intern Found Hope in the Moon

When Rose Ferreira first saw an image of a field of galaxies and galaxy clusters from NASA’s James Webb Space Telescope in July, she “went into the restroom and broke down a little,” she said. This “Deep Field” image showed galaxies not only sharper, but deeper into the universe than a similar image she loved from the Hubble Space Telescope.

“Being able to contribute in any way to the efforts of the team within NASA that released this new Deep Field just felt like such a profound thing for me,” said Ferreira, a student at Arizona State University who interned with NASA this summer. “I was just a little bit in shock for, like, a week.”

Webb, the largest space science telescope ever, which launched in December 2021, played a big role in Ferreira’s internship at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. She also supported a series of live news interviews for Webb’s first images and multimedia tasks for NASA’s Spanish-language communications program.

Growing up in the Dominican Republic, Ferreira said she didn’t have access to science education. She was taught skills like cooking and cleaning; she didn’t know NASA existed at that time.

But during the frequent blackouts in her village, when the Moon provided the only light, Rose Ferreira often wondered – what is the Moon all about? “The moonlight is a lot of what I used to see, and I was always so curious about that,” she said. “That obsession is what made me start asking questions.”

When she came to New York, she was placed in an underserved high school that sent her back multiple grades because they weren’t satisfied with her English language skills. She left and earned a GED diploma instead, hoping to go to college faster.

At age 18, Ferreira became homeless in New York and lived in train stations. By working as a home health aide, she was able to earn enough to rent an apartment in Queens and, eventually, get an associate degree.

Life threw other major challenges at her, including getting hit by a car and a cancer diagnosis.

Ferreira ultimately enrolled in a planetary science and astronomy degree program at Arizona State University. She received a “great birthday present” in the spring of 2022: her official acceptance to NASA’s internship program.

Among the highlights of her NASA experience was recording a voice-over in Spanish for a This Week at NASA video. She also served as a panelist at an event for the Minority University Research and Education Project, organized by NASA’s Office of STEM Engagement.

Ferreira dreams of becoming an astronaut and has a shorter-term goal of earning a doctorate. But the internship also fueled her passion for sharing space science with the public. Chatting with Goddard astrophysicist Dr. Michelle Thaller, host of the Webb broadcasts, was especially meaningful to her.

She has this advice for young people who are also interested in pursuing space science: “Coming from a person who had it a bit harder to get there, I think: first, figure out if it is really what you love. And if it is really what you love, then literally find a way to do it no matter who says what.”

Besides Webb, Ferreira is excited about NASA’s Artemis program, which connects with her passion for the Moon. Through Artemis, NASA will send astronauts to establish a long-term presence on and around the Moon. She’s looking forward to what Artemis will uncover about the Moon’s geology and history while the agency uses the Moon to get ready for human exploration of Mars.

“Even when I was living on the streets, the Moon used to be the thing I looked at to calm myself. It’s my sense of comfort, even today when I’m overwhelmed by things,” she said. “It’s like a driving force.”

Rose does have a web site! You can find it at www.rosedf.space. Hopefully she can maintain her web presence, as we have no control over social media companies owned by Billionaires and corporations, and we’re seeing that elected officials cannot be trusted and can turn against the people they are supposed to serve and do them great harm.

It looks like dowsingfordivinity.com also mirrored the original article. Awesome. We need to keep doing things like this.

Update: Another good post – The Attacks on Science.

Sewing to Repair

I learned to hand sew and how to use a sewing machine in school. I think it was 7th grade in a Home Ec class. The term “Home Ec” is short for Home Economics. Here’s the Wikipedia definition:

Home economics, also called domestic science or family and consumer sciences (often shortened to FCS or FACS), is a subject concerning human development, personal and family finances, consumer issues, housing and interior design, nutrition and food preparation, as well as textiles and apparel. Although historically mostly taught in secondary school or high school, dedicated home economics courses are much less common today.

The new term appears to be “Family and Consumer Sciences”, I say “new” because 500 years ago when I was in school it was just called Home Ec. We had a sewing class in middle school and I think I remember a cooking class in high school. Since my kids are adults I honestly don’t know what is happening in schools today, but I’m writing today to talk about sewing.

As I mentioned recently I repaired my old boots, and it felt really good to fix them rather than get a new pair. I was able to save money and opt-out of another consumer transaction. So when my gloves got a small tear in one of the fingertips I said “I should sew that up!” and I did… eventually. I’m not sure why it took me so long to do it, since it was a repair that took less than 10 minutes.

But as much as I call myself a maker and someone dedicated to DIY I really do feel I need to be better about this stuff. About repairing things in a timely manner.

I took a poll asking people the following question: Are you able to repair a small rip in a piece of clothing by hand sewing it?

Nice results! I probably fit into the “Yes – But it would not look very good” category and I’m okay with that. To be honest though I’m glad most people do know how to sew. It’s s great skill to have, even if you use it just for repairs and not for actually making new things.

Another Flat…

So according to my previous post I last had a flat tire in October 2024 (and August 2024). For the one in August I took it into the LBS to get fixed, but in October I changed it myself because damn I should DIY that stuff, right?

I probably got a puncture on the January Scrappy Hour Ride as my tire was pretty low at the end of the ride. Anyway, Matt was kind enough to give me a set of tires (nice tires!) so I pulled off my own worn out tire and put on a new tube and tire.

I actually had no idea the direction of rotation could matter, and I didn’t, notice the little rotation arrow until after I wrapped up the repair! Luckily I got it right.

Oh, I did end up throwing together a simple PVC bike stand. It’s not great (yet) but it’s better than nothing. It definitely helps when changing the rear tire.

(Note: I also got a flat tire with my car last month but I’m not counting that one.)

So hey, we are back in business and as soon as it warms up a bit, or I feel like suiting up again, I’ll hit the road and try it out.

Bike Nite (on the Fediverse!)

There’s a bike community on Mastodon (and/or parts of the Fediverse that connect with Mastodon) and you can be a part of it.

It happens every Friday 4pm Pacific time. I often forget about it when it happens but read the posts later, and sometimes even reply. It’s a synchronous and asynchronous conversation, and it works fine that way.

Here’s an example of the post you’ll see each Friday:

Our community discussion #BikeNite starts in about an hour, at 4pm Pacific. I post cycle-y questions w/ Q1, Q2, Q3; if you answer w/ A1, A2, A3, etc, it’s easier to match.

Tag #BikeNite if you want your answer to be more discoverable; follow it to see questions & replies in your feed. Boost & reply to replies to keep the discussion going.

(You can follow BikeNiteQ tag so questions are easier to find, but you don’t need to include this in your answers)

And yeah, #BikeTooter is totally a hashtag I follow and use myself.

There are a ton of bike people on Mastodon and all the ones I’ve interacted with so far have been awesome and helpful. Hey there’s even a bot that posts pictures of all the beautiful people who ride bikes in Madison called @cyclists_of_msn (We need one for Milwaukee!)
