Removing Pinion Gear From Stepper Motor : .sha VS pinion

Back in September I tested using a 12V 28BYJ48 Stepper Motor to move the throttle levers on my 737 Throttle Quadrant. It worked, but I believed it was at the limits of the motor's torque capabilities. If you look back at the video, you'll notice the motor jumps a bit when crossing the 45 degree point probably due to the sudden shift in weight. My gut instinct told me that I should upgrade the motor now before proceeding with the rest of the design. The motor size is the biggest (literally) h...

Power Supply Enclosure Project

I've been using a AC to 12VDC converter and a 12V to 5V converter on my desk for the last 10 years, to test out various project stuff. Recently I've been exploring stepper motors, and needed a bit more power than what my existing power supplies were rated for. So it was time for an upgrade. Thoughts The switching power supplies I typically see on the market have a metal frame but semi-exposed AC power connections. While they're cheap and reliable, I'm not a fan of this design and decided t...

DIY Boeing 737 Overhead Panel - Part 4 - Little White Toggle Switch Caps

The 737 overhead panel has around 70 toggle switches. The ones I've used are readily available at most electronic stores and also on eBay, and are great for their cheap price -- you can get 10 pieces for around USD2 with free shipping. They do the job, even though they're not quite in the same league as the original switches -- which is acceptable if you're on a budget. The original switches come in two varieties, standard levers and "locking" levers. The locking variety require they the lev...

DIY Under Cabinet LED Lighting

Yet another one of my under-cabinet fluorescent tubes went bust today. I decided some time back I'm done with fluorescent tubes, and planned to replace them with LEDs, so I had ordered the following from eBay: 5 meter 3528 SMD LED strip, Warm White (USD4.50 / MYR18.30). 110V/220V to 6V-36V LED Strip Light Power Supply Driver Transformer Adapter (USD1.39 / MRY 5.70) So now it is time to make use of them! I started by yanking out the original 1 foot fluorescent tube holder (it's held on with c...

DIY Boeing 737 Overhead Panel - Part 3 - Moving Gauges

Although I had planned to work on the annunciator lights next, I was still waiting for some parts, so in the meantime, I started work on the overhead panel's moving gauges. The 737 overhead panel has a number of gauges with needle indicators. Earlier, when I made the panels, I had cut out circles into the panels wherever the gauges are, and so now it is time to work on the actual mechanics behind the gauge. I used 2mm acrylic (RM5 per sheet from Art Friend at The Curve shopping mall), as I...

DIY Boeing 737 Overhead Panel - Part 2 - Panel Faces

Having built a frame and a stand for the 737 Overhead Panel in Part 1, I now look at building the "face" of the individual panels. Most of this is heavily inspired by Peter of Build a Boeing's youtube videos. Choice of Material There are a number of materials that can be used to make the panels. The ideal material would be 3 mm white acrylic/plexiglass, painted with the panel colour and then run through a CNC mill to cut them to shape, cut and drill out holes, and then engrave the labels...

2 PCs, 1 Speaker

Earlier this year, I got a new PC running Windows for my Flight Sim. I still use my Ubuntu Desktop PC/Server which I use for everything else, but some flight sim some stuff are Windows only and so ... ! Both PCs are wired to my triple monitors, and I can switch monitors over by selecting the appropriate inputs on each monitor. Sound was an issue however, as I only had one set of speakers. At first, I tried connecting the output of the windows PC into my Linux PC's Line Input. This way I coul...

DIY Boeing 737 Overhead Panel - Part 1 - Building the Structure

Having spent many hours on my X-Plane flight simulator, I've come to start using my displays only for the "outside view" from the cockpit. This means having the flight control instruments in hardware as much as possible. I've achieved this to some degree with the "glass cockpit" monitors I added a while back. However, when flying the 737 I still need to use the "virtual" overhead panel, so this was a good next target to move to hardware. You can buy fully functioning 737 overhead replicas in...

Upgrading Staircase Lights

Scroll to the end for latest updates! 8 Sep 2014 I woke up this morning to find the top side of my staircase mirror unlit. I guess the tube has blown after being on continuously for the last 2 years. Some background ... I have a large mirror next to my staircase. Since this area doesn't get much natural light, I got the renovation contractor to put fluorescent light tubes above and below the mirror. I keep these lights on all the time as I figured the cost of powering it is less than the c...

Replacing Faulty Power Supply Hack

I bought a 12V/5V DC power supply from Pasar Road a while back and it's gone bust ... the voltage and red indicator light are pulsing. Now I have no idea how the stuff inside works to repair it, so I decided to replace it. There are a lot of "frame-only" power supplies available on the market ... meanwell brand (I have one that's been running for years) and their clones, which are very reliable but the thing I don't like with them is that the AC wires are attached via screw terminals which ...
