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.

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.

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.

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.

Wheels

Re-solder Power

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).

EMAX Fix – Part 1

EMAX Repair Start

Hack-A-Thon Part 1

Lab Work – EMAX Fix – Part 1

On The Bench – TH2

Assess The Damage, Teardown

Back from the airfield, EMAX Fix – part 1. Be sure to check out the rebuild of in this series in the EMAX Quad Motor Rewire Video posted just before.

The airfield was clear, with no traffic, especially over in the helicopter and quadcopter area, so we were good to go. I unpacked the TH2 from its flight bag, got it out and up in the air with no problems. After a final check of the batteries and controller, we were ready to go. The weather was clear, and according to the flight radar, it was a clear day with mild temperatures and wind gusts of around 2-5mph. So, up we go!

Teardown

Reattach Antennae

Solder Antennae

Antennae Position

Lift is good, strong, and perhaps the easiest part of controlling the drone in flight. These drones when properly tuned , offer a smooth and vanilla flight experience. Be sure to check out the binding process using BetaFlight to bind/connect the flight controller to the remote.

There are a lot of things happening at once when flying the EMAX drones. You have to be mindful of your location, both as you ascend and descend. The flight went well, as planned/expected. I did a few loops, full power, turns, and hard bankings just to set the pace. Don’t forget to check the battery warning before your flight.

Power Leads, LED’s

Clip Leads

Resolder Leads

Clean Power Leads

Set Leads Properly

LED Seated

Now, at this point it was time to bring the TH2 home safely. As you can imagine, trouble came knocking. Damage report, minor issues included 2 LED strips out, severed antenna, severed power leads loose (+positive lead), and burned or malformed poly-frame. We fixed the issues by clipping and prepping for new wires, ordering new LED strips and poly frame, replacing the antenna, re-soldering leads, and shrink-wrapping wires where applicable.

TH2 Repair In Progress

eMax Fix – Hack-A-Thon Part 2

Lab Work – eMax Fix – Part 2

On The Bench – EMAX Tiny Hawk 2

In this case, we are addressing the second half of the build. Just to clarify or set the stage we have returned from the airfield with the eMax TinyHawk 2 in disparate need of repair. this is eMax Fix – Part 2. This is not the first time, nor the last time we will have this drone on the bench for repair. If you are interested in getting into drone flying, check out more EMAX Drone Kits, Drones and more here.

Total Damage, Repair

While difficult, soldering in new, nano-sized parts on these micro drones requires serious patience. Looking back, the drone may have encountered a gust of wind or air under the drone motor poly-frame; it’s hard to say. The crash wasn’t as severe as others, but the drone ended up sustaining more damage than usual. We’ve had to replace a fan blade, FC, or motor from time-to-time, but nothing like this.

Power On, Visual and Manual Checks, Power Down

LED’s Confirmed

If you’re looking for Emax content, give these a shot (in reverse order from this postings date) – Drone Accessories, ReFit Emax Flight Controller, and TinyHawk 2.

Wrapping up the final steps, we encountered a few minor issues: 2 LED strips out, the antenna, replace positive and negative power leads, same for two of the motor wires, and a burnt out/malformed poly-frame. To fix these issues, we clipped and prepped for new wires, ordered new LED strips and a new poly frame, replace the antenna, re-soldered leads, and shrink-wrapped wires where applicable.

eMax Quad Rewire, A Resolder & Power On

Patching Up the eMax Quad – eMax TH2

Lab Work – eMax Quad Rewire Video

We cover the eMax Quad Rewire Video for future reference… following the crash, a few activities are in store… time to replace the eMax TH2 air frame, Flight Controller (FC) or FC Board, motors, motor wires and fan blades. A quick peek underneath, revealed a few more items, copper leads, LED’s, alarm and flash FC board data to get the drone back to working condition (or as expected). This post really celebrates the fix itself, showing the motors work properly, alarm for arming/disarming the drone for flight and visual confirmation the LED’s do in fact work as expected.

The video, although short, helps to describe working condition, press play to reveal post soldering work on the bench and FC updates via BetaFlight. Time has moved on since this original video/video post, however, I wanted to share other eMax content where applicable. In fact below, there are a few links to see the work in progress or the actual fix while on the bench (which is a three part project). So, give those a look for more background or context for the final post here.
