I've been thinking of this "ban" thing. Maybe we should start planning to move from here. If you look at the startpage of forum, this is kinda the only thread that is still alive. Maybe DangerousPrototypes decide to shut this forum down for good, then what.
Not saying we should move now but rather start thinking of a move.
Hi guys, i'm working on my version again. What do you think about the shell of the USB connector? Should it be floating as in Sparkys schematic or should it be tied to ground/vss?
I've managed to fit both vertically and horizontal USB connectors, a bit crowded but it works :)
Thanks for the feedback! This is not the final board, more a prof of 'everything working'.
I have thought about mounting holes but I wanted to hear from you guys where and how many. As I have planned this board is not to be a front panel, rather solder wires to buttons and lcd, and the board can be placed anywhere. The USB-connector is a 'standard' one.
I'm thinking of a remake of the Unisolder5.2 Big changes are: 1206 components, easier layout regarding the LCD (no solder bridges), deleted unused component.
I used the version without bootloader. It works with the "standard" 0.96 oled display. My 2.42 oled is the one with black board, the DiyMore version (if that matters)?
[quote author="Doomedahab"]When askast posted a picture of his Unisolder with a 2.42" screen at while ago it certainly piqued my interest :). Based on his description I found that Aliexpress is awash with sellers offering this screen, including back board, for around 17 euros shipped. I just had to see if it worked, and it turns out it's basically plug and play, and compatible with the original firmware, just as askast said. This is the yellow version but is also comes in white, blue and green. Here's the link to the one I purchased:
Ok, first of all thanks sparky for a great project!
I've now finished the project and it finally works. Thought I would share some of my experience when building this.
1. Place all the components in right angle (90 degrees) especially R46, C60, R65, R63. Be careful, double check (I didn't) :) 2. You can NOT program the PIC via the PicKit2/3 standalone programming software. You have to put the programmer into MPLab mode in the standalone software then program it via MPLab. (took me quite some time and chips to figure out). 3. If you (like me) burn your 74HC02D, don't replace it with a CD4001B, they are not fully pin compatible :) 4. Bridge correct jumpers to the LCD (look at photos). 5. If you are going to change something in the software you need the right compiler: XC32 v1.33 and you also need to do optimization "s", so it will not compile with the Free version of MPLab X.
And last, if it doesn't work, check for bad solderjoints again and again.
