Re: what would cause the secondary encoder to stop working
On the encoders, Al recently had one that suddenly started sending out "short" pulses that got missed in the software. The short pulses were more or less random, but it caused the encoder to behave irregularly because the pulse train was screwed up. If you have a scope, check it out. Jack, W8TEE

Re: Successful JackAl Builds
All: Al and I realize that we're "too close" to the build and what seems obvious to us isn't to others. As a result, we will be updating the documentation, much like we did for the "wiring harness" documentation we recently posted. Right now, our web site has been hacked and our ISP seems awfully slow in fixing it. Stay away from the site until we tell you it's been fixed. This weekend is finishing my taxes, but we have set aside some time to improve the doc files. We appreciate your patience and honestly feel you'll find it was worth the wait. Jack, W8TEE

Re: what would cause the secondary encoder to stop working
Make sure it's "fried' before you give up, as we had one "come back to life" after a new regulator. Jack, W8TEE

Yes...i guess i should piece it together.. sorry... and I think my 7inch display just toasted.. weird that it should happen using stable Lab Power supplies. I did see AL's zener fixes to ensure protection....i guess too late. V n2aie |

Re: hamradiodesigns.com hacked???
Yes. we noticed it earlier today and informed our ISP. So far, they have not been able to eradicate it. For now, stay away. I post here when it's fixed. Jack, W8TEE

Re: what would cause the secondary encoder to stop working
VInce: I don't understand the request. The schematic is in the documentation. I've attached a copy here. Note the encoder connections are even separated out in the schematic. Jack, W8TEE

Jack, When will there a full schematic of the board be available? it would be nice now to have a snippet of that part of the board that handles all the encoders.. Also now making the ribbon cable for the encoders a bit shorter to eliminate any possible noise, as they are a bit on the long side (trying to decide case size) Vince n2aie? |

Re: JackAL source code
All: A long time ago, Al and I agreed to use the MIT License for our software, which says: Copyright (c)2018, Dr. Jack Purdum (W8TEE) and Al Peter (AC8GY)I have been remiss in placing this in the software's *.ino file, but will do so. If you plan on using/selling the software commercially, Al and I would appreciate a notice to that effect, as we would like to at least track its use. As to modifying the software, our hope is that people will use the [email protected] site for such changes. The decision about integrating any submitted changes to the code base that we maintain shall rest with Al and I. Users are, of course, free to implement any changes they deem desirable to their own copies of the code. Jack, W8TEE

Having downloaded the JackAl source code from? a couple of questions come to mind. 1. I don'r see a LICENSE file. Is the code Open Source? If so, under what license? 2. Is there a source repository somewhere where interested contributors can offer patches for corrections / improvements etc? Thanks, MC VK1MC |

Re: what would cause the secondary encoder to stop working
Al put a scope on one that was giving us trouble and found the pulse was about 1/4 the length it should have been. As you know, it is reading the pulse chain from both lines that lets you determine the rotation. I just bought a bunch of Bourne encoders? Arrow carries the Bourne encoder for about $1.35. Their ad doesn't say it has a switch, but the same part number on Mouser says is does. However, Arrow sends US orders overnight with free delivery! (I have no clue how they do that.) Jack, W8TEE
