Lab Work – Perhaps, the best way to show ‘work’ or work in progress; in most cases, the purpose is to highlight the struggle to find a solution, the test effort and the learning that takes place when fixing stuff. Or another way to share various phases of the problem solving process – hypothesize: test, learn and apply.

ASCII

ONE CODE TO RULE THEM ALL

ASCII Code Chart

Artwork – ASCII Art

ASCII Characters and Binary code…. got to love this stuff.

Back in the day, ASCII was our only form of communication. In the late 90’s beepers and rudimentary multi-key cell phones could only text the old way. I would spend hours creating the best coded language to share with friends and this chart of characters became art.

For you younger folks out there, who may not know what I’m writing about – “ASCII, is a standard data-encoding format for electronic communication between computers. ASCII assigns standard numeric values to letters, numerals, punctuation marks, and other characters used in computers. In full: American Standard Code for Information Interchange.” – ASCII – Per Britannica. Take it or leave it. We use it for art… and pictographs.

Those days are in the past, I know. But it was still, fun while it lasted. Here’s a list of all the characters and binary codes to inspire your next piece of art. Don’t be shy, don’t keep your art to yourself! Share it with others.

RAW ASCII (has spacing issues, we know… #$#$@ browser… may repost if it doesn’t work)

Dwight

Oh, and before I forget, we aren’t talking about generated artwork… we are talking about the good, the bad and the unusual character art. My personal favorite is the local “Skunk Ape”, “Grassman” or “Alien ‘Big Foot’ Hunter”. Just a few I recall from back in the day. Rules were broken below when ‘creating’ these ASCII images. ((SHOUT OUT)) to the artist who converted these TUX and Dwight images to ASCII. The TUX ‘piece’ may need to find it’s way onto a t-shirt or hat.

borg2borg v7

Twitter Bootstrap v7

Borg2Borg Unit

Borg 2 Borg A Bootstrap Framework

Lab Work – Web Work

Bootstrap’n Journey number 412 version 7

I’ve been wanting to share this for awhile now, especially since version 5 has been out for some time. Borg2Borg v7 is now available and ready to use. It has been posted on the web. out and ready.

The sites mentioned above are intended for reference. Please treat those links as such; reference materials. The goal is to provide working templates for anyone to use and help others learn various coding languages, such as PHP.

Iterative Work in Progress

This is considered work in progress, code has been moved from our Git repository (moving away from Github). This code will live under the borg2borg domain for now. Please excuse the dust as some sites may require rework during the transition to the new space… However, we are transitioning away from Github. Therefore, website references like Borg2Borg v7 or reference materials will also be published on each specified domain. Additionally, we have started the conversion process, and all public/private/secret Ghists will be used as code references. Our goal is to assist people in learning code, such as Python, PHP, jQuery, JS, etc., for public consumption in the near term. We aim to meet and exceed our goals by providing code reference materials, coding examples, educating, and sharing language challenges and techniques with the masses. You will see coding examples presented in the following format or treated with Bootstrap HTML Treatment.


<h1> - PHP Print Example<h1>
<h3> - Calculate and Print<h3>

<?php print(1 + 2) * 3; }?>
Here is a quick PHP print statement, utilizing the Bootstrap code treatment for the purposes of an example, the console will calculate and print the calculation to the browser.

Again, for probably 2 months now or so, we’ve converted all Github/Ghists to a companion file within the site folder. Next step will include a conversion to a database. At least that is the goal, assuming time is available.

Same for Django, this might be ‘jumping the shark’ as I want to get a working version of Django up on the ole’ web-server and see what we can do from there. I guess the overarching goal is to offer language/code reference material and Bootstrap examples. Local examples, jQuery – Astrononymous, BurmPy and 1Fyr.

So, lots of work out there, ton of things to do, clearly… not enough time in the world to work on side projects. We will get there one day at a time. Enjoy!

1fyr Bootstrap

Versioning Update, 1Fyr.com

1fyr Bootstrap v3

1FYR, 1 Fire, once a month

Lab Work – 1Fyr

**UPDATED** 1FYR.com – 1Fyr TWBSv3 Update

It’s time, time to update the version for 1Fyr, 1Fyr Bootstrap v3. Like many things in this world, it was time for a  tune up, we are moving 1fyr.com to Bootstrap v3. So, what does that mean?

Tune up includes, code clean up, the removal of any deprecated elements, code and/or elements no longer being supported moving forward. WP jargon went out with the ‘bath water’ as did some of the bloat.  V3 added a framework of sorts, adding Bootstrap framework to this site. With the code change, we’ve made some website improvements: show/hide div’s on the latest fire, archived videos presented in a more favorable fashion and the Jumbotron…

While the yard is being worked on per say, (2 months now) the fire concept has been put on ice to say the least. Again, which aloud me to refocus on the site, code tweaks and more. We kept it simple using TWBS v3. Once we get the backyard up and running again, we will post videos…

While we wait, or in the meantime. For the sake of historical reference and ultimately, how we got here. More information can be found here, about campfires and family time  on 1fyr.com. Or, you can stay here, and read about the 1Fyr build and/or 1Fyr updates.

Calc Rework

Let’s Get A Fix In Place For This Calculator

Calculator Work, Fixing the old calculator

Lab Work – Fix the Calc, Calc Rework

Broken Calculator, Let’s fix it. Don’t want to keep this little piggy waiting!

Calc rework started a few months ago. We’ll keep this post short and brief… This calculator showed up on the work bench with minor issues. Connections all busted, it looks like an animal, a vacuum, nature or something was able to get to the calculator and internals.

Anyway, after fixing a few connections and installing a new CR battery, this little piggy is like new again! Easy work, no major issues with the main board, keys, case or display. Quick fix.

Calculator Fix
Battery/Resolder

Look Here

Look Here

Lastly, I decided to keep little ‘piglet’ sticker on the old calculator because it gives it a new look. It’s a great office calculator with big keys and a large display, making it easier to use than those tiny digital smartphone keys. I reminds me of the  old Printing Calculators, kind of like this Sharp Printing Calc. It brings back memories of my parents having used one around the house when I was a child. If you enjoy reading repair articles, consider learning more about robots, remotes, drones, and computers. Wiring guides like this ADT Touch Screen quick reference, keep this handy for future needs, power outages or battery replacement.

Lab Work – iRobot Back At It

Got a broken robot? We can help! Some might say that’s the worst, but fear not – the iRobot – 900 Series is here to save the day. 

Let’s start by fixing this thing with an iRobot Roomba 900 Series Teardown. The great thing about iRobot/Roomba products is that they are easy to fix! Unless the board is fried, the main housing is smashed, or the plastics are destroyed. Even in those cases, parts are fairly easy to find. The key is to source, clean, install, and maintain what you have. Most, if not all, of this particular Roomba was fine. A good cleaning at the end of the repair was worth its weight in gold.

Test Run

For those of you who don’t regularly electronics, robots etc. weekly, monthly or ‘NEVER’… friendly reminder, whatever the electronic device may be, they do yeoman’s work if you take care of them after every one or two uses. Additionally, the more you maintain them, the less you will have to throw. Remember, no pain, no gain.

A few tools to mention below, reiterating the previous comment, these are fairly simple to fix… for now. Learn the art of robot care, become a ROOMBA master sensei. This is a huge advantage for iRobot:

  • iRobot Home App
  • Philips Screwdriver (Rechargeable Drill* DeWalt 20v)
  • iRobot – Brushes, collector rollers, caster wheel and filter
  • Cleaner – Windex
  • Cleaner – Sprayway
  • Compressed Air
Links, Conclusion and More Repairs

In closing, I’d like to share some other articles, more recent articles on robot repair, 3D printer upgrades RC (radio controlled) and robot repairs, check out these articles.

Moreover, let’s look at a Bench Power Supply – Matrix Bench Supply, the need to power on electronics when the damaged robot or device is on the bench in pieces. Next, and one of my favorites, the Maytronics Dolphin On repair, explore water intrusion and effects of water intrusion, water damage and power unit swap. How about the Ender Direct Drive Upgrades – TPU Post Processing Update, a 5 part series on filament types, application of filaments, upgrades, troubleshooting and more.

Final link, check out the EMAX TinyHawk Repairs… more fixing, soldering, and flying. There are more articles in the TinyHawk series, approximately 6 or 7. Be sure to check those out, as well as the iRobot series continues. More recent work, but it helps tie in ‘process’ and troubleshooting unknown errors and testing.

The teardown and do the Late MBP Battery Swap Repair

Let’s get it! Before we begin, below are photos of the repair process. We are working on a 2013 MacBook Pro “15 Retina laptop with a new battery. Please ensure that you have selected the correct replacement parts, preferably OEM battery parts.

Find The Right OEM Parts, Find Primary and Secondary Parts

First, it is recommended to use OEM Parts, and even a second-hand OEM battery may be a better choice than non-OEM part in this case. OEM parts can be purchased from various websites such as eBay, Apple Parts, Apple Self Service Website, and iFixIt. When performing the repair, it is important to be cautious and take your time. Power and grounding are crucial, so be careful not to energize parts once the case has been unscrewed and removed. Additionally, it is helpful to have a few other items on hand for the repair.

Tools and Repair Kit for the Late MBP Battery Swap

Some other tools to have around the shop might include the Jakemy screwdriver kit, which  contains Torx, hex and star bits. These are key for newer technology bolts and screws used in the assembly process or to hold hardware to the board. Additionally, it’s important to have glue tech adhesives and glue release, gloves, safety glasses, and a welding/soldering mat. These are all useful bare minimum tools to have, including glue release, a tech screwdriver set, and glue adhesive.

Lab Work – 1FYR Update And Other Work

Update: The move to Bootstrap V3… in coming soon. Stay tuned for that.  But for now, back to the test case, SOLVER. Let’s get you up to speed…

(<< REWIND) We were exploring ways to play around with our cameras, light/exposure, and enhance our film during dusk. Dusk, after twilight, is being the most challenging time. You might not know,  but some of the best light is during twilight . The sunset light here on the coast offers dramatic colors, landscapes, shapes, and textures to capture in images or videos. Texture refers to the subtle and stark contrasts of color. (>> FF) Our experiments continue as we have some fun along the way. Campfire, music, food… what more could you want?

As you will see, fires can be unpredictable, especially at dusk. We enjoy the process of building, stoking, enjoying and extinguishing a fire every month or so. We cook up some burgers, grilled sandwiches, hotdogs, and s’mores if we’re lucky. And there you have it – INTERNET CONTENT!

1Fyr Updates
Fire At Sunset

S'mores Time

S’Mores Time

I’d like to see us get to a point where we can post more videos, more often, weather permitting. Anyhow, the goal of this test was to capture and correct lighting affects. We use Adobe Premiere (Not A Sponsor) and share with you via the interwebs. We’ll post some Premiere content in next quarter or so. That might make some good content as the video/editing process is hit or miss as a noob. You know the sunlight, sun angle, twilight and how/what device captured the subject; meaning what device or camera was used to capture said subject. 1FYR Update, we chose fire, of course. A caveat, (loophole) we don’t see snow here in the South… Snow can be fun to film. All too often I forget/fail to mention the rainy season as well. Pre/post rain storms can create dramatics, drama that’s what we need! Before I move onto the subject of this post (yes, side tangent…) Don’t forget to check out 1fyr.com.

The next test case will include steel, torches and welders, yet to be purchased… Still trying to iron out what that might look like on ‘film’. But we have a few contenders to start, need to fix the campfire tool set. Specifically the shovel has all but worn through its welds and sits in two. The campfire brush is worn out to say the least, adding that to the refresh pile. The campfire grilling surface (an old repurposed baking rack) might need a little attention as well. There are more, but hopefully we’ve captured your attention.

Lastly, we will probably review some gear, welders, torches, protective clothing etc etc. Leaving you with a cliff hanger of sorts. More to come…

ReFit EMAX FC

I thought we could revisit the EMAX FC repair on the EMAX THS. I’ve want to follow up on the previous post, focusing more on the specific, showing the repair process and refitting the EMAX FC. Along the way, I’ll share additional photos of the process as well (in case you come across this article and are in a similar situation with a failing FC). Let’s cover the entire process from start to finish – disassembly process, cutting soldering, and test flight. Once again, soldering/replacing the EMAX AIO FC. Enjoy the photos.

Once you have all the parts, fitted, soldered and ready for flight, we will need to configure the FC. Rest, bind, configure and fly, in that order. Check out the EMAX FC and BetaFlight post for more information. You can also learn more about the repair, configuration process and in-flight troubleshooting. If you are having troubles, log into the EMAX Support Portal for assistance with your EMAX products. Lastly, I want to reiterate the steps to fix the FC – Support EMAX THS, remove EMAX FC screws from the Drone PC frame, Cut/Add Connection to Board, Re-Attach New Power Connector with the Battery Carrier”. Time has  moved on since the original post, I wanted to share other Emax content where applicable. If you’re looking for Emax content,  give these a shot (in reverse order from this postings date) – Emax Fix Part 1 and Part 2, Quadcopter Rewire, and the TinyHawk 2.

Like most things, there are more ways to make your cake and eat it. The Chrome extension is helpful when bouncing back-and-forth between systems/releases/drones etc. I run Big Sur MacOS, Ubuntu Linux and a Win Server 7… it’s handy here, as the config remains the same, helps to maintain a certain sense of sanity. Especially when you’re a NOOB.

Two, from time to time, I run my Win7Server via MS Remote Desktop or Linux instance via Oracle’s Virtual Box. One advantage might be number of USB ports available… as you know, most MacBook Pros are limited to 3 of 4 USB-C ports. Unless you run usb ports, which I don’t care for (B.S. but that is for another day). Anyhow, regardless of how you run Betaflight, be aware of the nuances, versioning and pitfalls with each new iteration or release. T

ake notes, take screenshots, vlog about it… anything to help you remember the ‘deltas’ (change) over time. These will come in handy the next time you crash or repair your drones. Notes and support can be found here: Betaflight – Github Notes/Docs Moreover, issues came up when I swapped AIO boards, soldering power and reconfiguring modes. For more information, I posted more about the config, various configs like EmuFlight and BLHeli, look for 8/17/2020 post – Hack’r-A-Thon//
