Ok, every plane needs a set of rudder peddles! There are a lot of choices, and then everything in between. The pedals show below, Figures 1 to 5, are commercial products priced from $50 to more than $500 dollars! Figure 1 is my old Thrustmaster but it has no toe brakes and its interface is a Gameport! Figure 2 are from CH Products, and not toe brakes at about $100. Figure 3 are the Logictech G pedals and they come in at about $125 with toe brakes and are nice for the price. Figure 1 Figure ...
Well, I figured it out! Since I am using an Arduino Mega with 4 serial ports so what's the problem? All Slaves and Controllers use RJ-45 connectors and ethernet cable. There is very little magic here as Arduino has built-in drivers for the serial ports. I stay away from the serial port 0 has that has the USB on it which is good for loading and debugging. The only thing you have to be careful with is that TX is always wired to RX.  So, to sum up, this table below: All wire cat5 cabling is s ...
The last time I blogged about this unit was back in October 2016. So I uncovered it in the "un-move" along with a cable which I had thought was just a spare but nope it belongs to this beast. Basically, it's a Resolver which drives the 'bug' or pointer and 'OBS' there is also a manual control to set the bug on the heading you desire. Currently, the 'bug' is at 0, and the 'OBS' which is the reverse is on 180.   CPP Phase Shifter 30 ~ Wires Type PS-17-E-1 Stator 2 phase 5 volts Black & ...
Ok so I have messing about with Edin Lite, which is only Half-Duplex and has a fairly small package size.  So since I have an abundance of RS485 Modules I decided to try Full-Duplex. This is fairly straight forward, and I doubled my bandwidth. Whoopee! I don't have all the  kinks worked out as of yet, but when I do I will post the source code in pd! Below is what we are all used to:  One the Right side is what I how to get working! ...
In the dim past, computers were so large that they could take up a large amount of space and have their own cooling.  Then in the '70s, there was the minicomputer. This is an Interdata 70, in their later models they changed the color of the rack to dark blue. Then in 1981, IBM changed the game, enter the PC even with very limited memory, sometimes only one floppy disk and the most hated piece of software ever WordStar.   You could get some work done. In my opinion, the first real SBC w ...

Well, the last attempt of making a circuit board was an utter disaster. Figure 1 Figure 2 Attempt number 2. I went over to my local library which has a small maker space where they walked me through Tinkercad. My goal was to use their 3D printer to print an artifact so I could test for fit.  Below you can see the nice pink artifact1 and installed without screws2. The artifact was very close and only required minimal sanding. For my next trick, I will trace the outside of the artifact on s ...
Well, I just found out some errors in my part ii Fuel Load Indicator addendum interface table.  Apparently, I was using the wrong part's pinout, "So without further eloquence"1, here are the new tables.   Signal Type Signal Color Data Lines Address Lines Control Lines U1 Control Lines U2 Notes: U2 is closest to the off-board connector. Both Logic Ground and Supply Ground are tied together. In the connector table, a 0 at the end means it is LOW ACTIVE Comments: For some unkno ...
Well, really need to finish something around here so I will take up where we left off with the fuel load indicator, in parts 1, 2 and 3. And I can't go on without a PC board so I decided to make one this evening. First I need a piece of Vector Board to lay the board on.  The problem lies in the fact that that I don't have any way to get reliable dimensional info and then the 18 pins on the board that connects to the display saying that that means that the two boards have to line up. That is ...
