Now is a good time to fix up the overlap between the SID "R" LED hole and the PT-10 case mount. Solder switches. Some switches overlap the LCD PCB! Turn it PCB side up, trim the leads to 1mm above PCB, and solder the second lead of each LED, and also do a proper solder joint on the first lead (if it wasn't done properly the first time). Then after you have a frontpanel with screws and threaded spacers attached with JB-Weld, it is best to solder the tactile switches FIRST and then use these (along with the PCB and panel attached) to aligning the LEDs in the panel holes so they stick out from the panel the same amount as the shafts of the tactile switches. I cannot imagine having a 4-minute countdown on my head trying to do 23 blobs on the panel AND THEN put the panel and PCB together. Put the panel on top of the PCB, guiding it onto the PCB gently with the screws as a guide. The flat side of the LED should match the flat side of the symbol on the PCB. The flat side has the cathode. Also the shorter lead is the cathode.



I solder the shorter lead first, so that the longer lead can be used to move the LED if you need to adjust the LED position later. If the LED leads are really long, you can trim all the LED leads to 5mm above PCB, to make soldering easier. This is only possible if the switch shafts are all the same height (which will happen if you've screwed the PCB and panel together with screws in all the threaded spacers). Then gently lift up the PCB until the switch shafts go into the holes. The aim here is to make the LEDs poke out the same distance above the panel as the switch shafts. Put the LEDs in the panel holes. It takes a while to put a blob of JB-Weld on 23 spots on the panel, making sure the blob is neither too big or too small, and even with the non-Kwik stuff, towards the end the JB-Weld was a bit too gooey, like peanut butter instead of like honey. 20 hours of just waiting (yes you need to do two separate gluing stages) might be torture but it is worth it in the end. Please wait until someone has tried this method before gluing to the panel.



If I have not explained myself enough, then please wait for a more detailed explanation in the construction guide. I advise people NOT TO SOLDER ANYTHING to the control surface PCB until you read the finished control surface construction guide. I still have not fully completed the control surface construction guide. Don't be impatient, you've just spent lots of money on these nice panels, what is control cable you don't want to feel rushed in this construction stage when you're trying to be ultra careful not to make a big mess and connect the PCB and panels together slowly. BLACK MARK GOES TO POINT OF DIODE SYMBOL ON PCB! Solder diodes. The diode to the left of the switch labelled "SHIFT" on the panel is too close and can prevent proper positioning of the switch. Once they are together, you can use the nuts on the screws to hold it together. I use the front panel that comes with the PT-10 case, this is very flat, and you can rotate it to see the gap around the edge, i.e. how high the switch shafts are holding the frontpanel above the surface. Put the PCB in the PT-10 case top where the panel would normally go, so the LEDs can be put in without bending the leads.



PCB (with the spacers still attached) using screws to hold it together. And using a Pi Zero W would help greatly with the software side of things. If you’re using Teletype with just one or two other modules, you probably do not need a powered busboard. Buying property with unpaid property tax, mainly in case you’re trying to get it for simply the belongings tax, is almost impossible at a tax sale. In the case of aircraft, where the pilot will need to actuate the rudder throughout the lifespan of the plane, conduit lined with teflon, for instance, promises the pilot smooth, fluid control over the yaw of the aircraft. This will help you find and navigate through the channels more efficiently. Once saved, accessing your favorite channels is as simple as pressing the "Favorites" button on your remote control. Conversely, pressing more and further on the pedals results in more aggressive change in flight characteristics. However, the teleprinter proved to be more reliable than its replacement, so it remained in use as a backup for over 50 flights, often printing thousands of lines per flight. However, this might affect your ability to adjust LED positions later if some LEDs were not correctly aligned in the panel holes.
