Calc Rework

Let’s Get A Fix In Place For This Calculator

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.

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. Or, you might be interested in the Nano Whisk Fix, the M1 MBP Repair, or the latest Dolphin Pool Robot Fix. Feel free to leave a comment below and let us know your thoughts!

ReFit EMAX FC

Cut, Fit & Refit

EMAX THS & Flight Controller Board

Lab Work – EMAX Flight Controller

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.

Lego Train Depot

Project – Solder Station Build

Lab Work – Ready For Service

BOOM! Soldering Station Done

It’s always great to have Legos handy, especially for building the Lego Train Depot. This model features a big smoke-stack and a unique, oblong, and somewhat unstable shape. This is where Legos come in handy. With a few blocks, you can create your very own DIY solder station. You can buy a 300 pcs set or purchase Legos in bulk (4lbs) if necessary, along with some connectors. You can find sets at garage sales or use ones you already have in storage. Look for bargains to gather the pieces and parts needed for these projects builds using Lego bricks..

For this article or application, I believed that stability would be crucial. We needed something to immobilize and stabilize the train while it sat on its top. Ironically, the train spent more time upside down than right side up. This allowed us to solder the necessary wires, clean debris, and wipe away the age. Yes, the model train spent most of it’s time on the upper ‘casting’ (locomotive mold) so that we could access the electronics housed within.

Rewire – AF 312, with the AF 312 Wiring Schema

I thought this might come in handy for those of you out there, tinkering and wrenching with old model trains, trying to keep our historic, scale models running smoothly. I recently, needed to rewire a 50’s AF 312 Locomotive and Tinder (using the AF 312 Wiring Schema). Also, for future reference, two other models are included the diagrammatic illustration.

The teardown effort went smoothly, with only a little trouble encountered with the tinder card. Resoldering the burnt wires wasn’t a pleasant task. However after swapping in some new wires, fresh resin, and solder, we were back in business. We cleaned out the tinder cart, removing any debris, paint, and oil deposits. The same care was taken with the wheel set, ensuring the original parts ran as they should. This effort aims at restoring and bringing the model trains back to life.

Next, a similar rewire requiring coils is needed for this locomotive, but it does not have those parts. Those items seem to be missing at this point, causing a wiring and parts issue. They appear to be charging coils and connections on the circuitboard, solidifying the connection underneath the locomotive’s body. Unfortunately, this train seems to be missing parts, possibly due to age, wear or simply being lost. Unfortunately, these models need replacement parts for an aging model locomotive set so that this train can ride the rails consistently.

The rewire challenge is straight-forward, but be prepared to face challenges. Preparation is essential! Check back soon, to see if we can locate the required pieces. In the meantime, visit an AC Gilbert American Flyer train website – www.thegilbertgallery.org that cover s-scale trains, including the #336 Union Pacific Northern and the #293 New Haven Pacific locomotives which are similar to the train we are refurbishing (AF 312 Wiring Schema).
