How did you connect the trim pot to the standard potentiometers?

How or by what means where you able to connect the trim pot to the standard pot. I love the idea, but I'm struggling with the method you used. Thanks

I've attempted to build your Variable Bench Power Supply a couple of times, and after watching your youtube presentation and reading your post, I have not been able to get it working as you show, Couple of problems I ran into was while testing the LTC3780. I kept getting a red fault light and no green led. I finally (on my 3rd board) found some informatio on the internet that you need to turn the Volt and Amp adjust pots about 20 times counter- clockwise that cured that, Now the big problem, How did you get the two pots (a 200k and a 500k) that you suggest to work in your circuit? There just doesn't seem to be the adjustment range to make the darn think to work. Which brought me back to the red fault led again. Went back and re-installed the original two pots and every thing works that wa…

Went back and re-installed the original two pots and every thing works that way. Not very practical for use as a variable bench power supply. Any suggestions?

I'm not being able to compile your code. It's hanging up on this piece of codeI'm not familiar with "showDigt() syntax.clr();for(i=0; i<num; i++) { if(digtrans[i]==0) { dy=0; showDigit(dig[i], digPos[i], dig6x8); } else { dy = digHt-digtrans[i]; showDigit(digold[i], digPos[i], dig6x8); dy = -digtrans[i]; showDigit(dig[i], digPos[i], dig6x8); digtrans[i]--; } }

Can't get the darn thing initialize. It complies and uploads okay but I get nothing.Here's what I got on the serial monitor:⸮E⸮|v⸮H$48⸮p`:`⸮⸮Failed to open config file*WM: Adding parameter*WM: timeZone*WM: Adding parameter*WM: militaryNo Double Reset Detected*WM: *WM: AutoConnect*WM: Connecting as wifi client...*WM: Status:*WM: 3*WM: Using last saved values, should be faster*WM: Connection result: *WM: 3*WM: IP Address:*WM: 192.168.1.122WiFi connectedIP address: 192.168.1.122Starting UDPLocal port: 2390*WM: freeing allocated params!Any Suggestions?

How do you set the correct time?

I'm loosing it here, help. What programmer are you using to up load the sketch. I'm not sure my FIDI board is working so I'm programming the Mini Arduino Pro with an Uno. This setup works because I loaded and ran the Blink program with no issues.

Did anyone figure out how to display inches or feet?

I've put the project together again and now I'm having problems with the data displayed.All I get is a date of: "Monday 165/165 45:165" and the temperature of: "-1.75C, -1.75C, -1.75C. I've tried other DS3231 modules, switched batteries, I've even unplugged the DS module completely and I always get the same readings.Any suggestions out there?

I have a couple of questions about your "Universal USB Keyboard with RGB Switches." Cool project, looks useful. In the text portion of the Instructable it talks about a TLC5904, while in the schematic it shows TLC5940, and it shows 2 28 pin ICs. Your PCB indicates only 1 IC with 24 pins.The other question I have is, I don't see the interface with the Arduino Pro Mini. You wouldn't happen to have a Fritzing of your diagram, and a more detailed PCB design?

Love the useless machine. Have you had tome to creat another Instructable around it?

This is a neat project and not too difficult. I did have some problems with it to begin with but Ludek and I worked it out. The most recent code is version 7. Can't guarantee anything before that. First my receiver wouldn't lock on to satellites I found out that it was, I just didn't know what information is contained in a GPS sentence. A google of GPS sentence breakdown helped a lot. Secondly, Your supposed to get a $ at the beginning of the sentence. I never got one. third and this was the biggest problem I had. My 8x16 display was offsetting too far to the right and the display was not inverted to make a readable display on the windshield. After trying to run some of the other MD_Parola examples and finding they were garbled. I found an article on the internet that told how to run a te…

I found an article on the internet that told how to run a test program and adjust the MD_Parola and MAX72xx include files to correct the issues I was having.That did it.

I'm having problems compiling your sketch. I'm getting:error: void value not ignored as it ought to be done = radio.read(msg, 1); ^I've followed your code exactly as you have it with the exception of the CE, CS pins are 7 and 8. and are noted so in my sketch.Any thoughts?

Has anyone found a way to turn down the brightness on this project?

Can the temperature be changed to Fahrenheit, and where in the code is it best to do this?

This works great, except the text scrolls bottom to top on an 8x32 display instead of across(32 wide by 8 high) it. Am I doing something wrong? It's like 4 rows of text zipping by from the bottom to the top (top to bottom depending how your holding the display.)

At the beginning of the sketch remove the #include <Time.h> entry, and re-include it. You should then have an "#include <Time.h>" and a "#include <TimeLib.h>". That should take care of the 'tmElements_t' error.

Jeffreye, Help! how the heck do you change the year in this sketch. There are a couple of us out here scratching our heads trying to figure out how to change the year. I've uploaded and incorporated your time setting code, and for the most part it works, thanks, but I can not for the life of me change the year in the date line.

Nope, can't change the year it's really driving me nuts. If anybody out there has a solution, please give dancopy and I a reply. Thanks

Okay, I'm into brain meltdown. I cannot adjust the M/D/Y no matter what I set it at in the Set Date/Time module you sent me it refuses to reflect the change.

I've setup the code as downloaded on my Mega 2560 board and looked at the change recommendations below but all I get is a single line at the bottom of bright red LED's. Help, I'm fairly new at working with these large (64x16) LED arrays.

Hey, great, thanks for the fast response.

Where did you find the 16x 64 displays? All I can find are 16x32. Thanks

What???? Sorry too much i/p, o/p, xyx for me. Mine is working great, but can't interface with your acronyms.
