Working with veroboard/stipboard

$

Hi guys, I am new to Fritzing, but have been making my own PCB etc since at least the 1970s. I recently decided to make a project that was basically a small 12V gel battery charger and LED state of charge indicator. I decided that rather than make a PCB I would use veroboard, as for logistical reasons at the moment etching a board is not really an option. I used Fritzig to design the board but there are a couple of things that I would like to suggest that would have made it a lot easier, or alternatively if someone could tell me how I've missed the obvious way the software can do what I'm suggesting that would be appreciated!

It seems to me that the program only allows a component side view, a way to flip the design between the top view and the bottom view would be great. This is especially annoying with ICs as the pin position is very different from each side.

Secondly I had a play with trying to create my own component by editing an existing one, but when I saved the part it complained about unassigned connectors in one view (it did not specify which view) and try as I might in each view I could not resolve the problem. I assume I must be doing something wrong.

Thanks guys.

Yeah, you can't see the other side of stuff except in PCB view. Some people make a stripboard in PCB view, but it is a bit of work.

This vid might answer the part creation thing.

Done. Now what?

The Fritzing command segfaults the same way.

Also, sudo apt-get build-dep fritzing installed a LOT of packages. Is that supposed to happen?

I would think if you had fritzing 0.9.2 from the repos install before, there shouldn't have been many more packages t install, unless you had uninstalled it prior to the above command.

Thanks for the information! Would you help me on the whole charging circuit?

I'm not sure I know enough about lead acid chargers to do that safely. A quick google search indicates that there does need to be over charge protection but I don't know how to do it. You would be best off finding help in a forum where there are people that know exactly what they are doing (at least on the charging end). Various types of boost/buck regulators are available from ebay for 10s of $ that will put out 48V (as noted you are going to need that because of your
generator which will give you variable input voltages which is bad for charging).

There are actually a few more problems than that. There is a bus on pins 1 and 2 and 3 and 4 which short pin 1 and 2 and 3 and 4 (and since 1 is +5V and 2 is gnd, I'm fairly sure this wasn't intended and is a holdover from the cloned part :slight_smile: ). As Old_Grey noted the pcb is in rough shape, no copper1, various pins have incorrect names in the various files. I've cleaned most of that up, but connector30pin (the 3.3 V output) is giving me grief. It is missing its terminal entirely in pcb view and is grouped oddly compared to the others and I haven't yet been successful in getting a configuration that works (I may just try deleting it for now to see if the rest works). If I can get a config that mostly works (the pcb is going to be difficult to fix totally without a board), I'll post it here for you. The breadboard view is a work of art and mechanically accurate as well as far as I can see. It only needed to be aligned to the .1 grid so it lines up correctly.

(Edit: My bad, its schematic view that is missing the terminal for pin 30 not pcb).

Fritzing window sizing on ubuntu 16.10 issue

$

Steps I took that resulted in the problem:

pulled the correct arch of the linux fritzing, extracted and ran the Fritzing executable. application loads but looks 2x the scaling on my 1080 resolution
...

What I expected should have happened instead:

the window would be full screen to my resolution not larger than the screen.
...

My version of Fritzing and my operating system:

16.10 ubuntu
3.20.4 gnome-shell
0.9.3b of Fritzing
...

Please also attach any files that help explaining this problem

0.375in Pin Spacing on header?

$

I'm trying to create 4 pin header with 0.375in pin spacing on my PCB. This is to interface with an bunch of odd sized ribbon cables on the gadget I'm trying to modify.

I figured I could use the generic Female Header and set the pitch, but it seems that the pitch is restricted to the a preselected set in a drop-down? Is there a way to set it to 0.375" pin spacing?

I tried editing the part, but after opening it up in the (new) parts editor, I was unable to modify the PCB at all.

Alternate suggestions are welcome too. I just want 6 lines of 4 holes on my PCB with 0.375" in spacing.

OK, this was an interesting exercise as your part is broken in interesting ways :slight_smile: with the note that I'm not an expert at any of this (I'm just learning Fritzing part creation and know very little about svg) here is a corrected version of your part. I removed the bus elements that were shorting +5V to ground (left over from the cloned part I expect), corrected the varying references to pins (pads, terminals and pins intermixed in non functional ways), and finally found the worst error which is at pin 4 you switched from Fritzing's one less than the pin number to the actual pin number, meaning there was no pin4 and was a pin38 which dosen't actually exist. As well the PCB svg was so broken that I tossed it completely arnd replaced it with the pcb svg from a generic IC of 38 pins (giving the necessary number of pins in the correct groups) after removing the translates that Inkscape likes to add, so the pcb svg is in actual thousands of an inch coordinates (at least under Inkscape, I see you use something else). Two things that need to be done: schematic some of the lines are fatter than they should be as I don't know how to manipulate paths and had to use Inkscape's graphic manipulation which thickens some of the lines which I don't know how to correct. It would also be better to use rectangles with rounded caps (as many of the other parts do) but I was too lazy to make that change, you may want to do so. On the pcb as noted it is currently untranslated (and you probably want to keep it that way) and should be mechanically mostly correct (assuming the breadboard view is mechanically correct which it appears to be), however all the text is missing (I was too lazy to add it in as I didn't need it to verify the pads worked as expected) and the position of the to lipo battery pads are just a guess, so you would need to adjust their position to match that of the board (since I don't have a board I took a guess based on the breadboard position). As well the drill holes have been adjusted from the standard .035 for an IC socket to .038 which fits the .1 headers which will fit in to the connectors on the module. Modify if desired. Comparing the svgs and fzp file from this version with your original should show you what I did (as I said I expect you know a lot more about svg than I do), but if you have questions feel free to ask and I'll answer as best I can.

0.375in Pin Spacing on header?

Assuming I've understood your request correctly this should do it. 4 .1 pins (.038 hole) on .375 centers. I only changed pcb, breadboard is still .1 spaced but I can change that if you need it.

Making a circuit isn't a problem, its knowing what the circuit needs to do that is the problem. A partial list of the things I don't know:

1) can you charge series connected lead acid batteries? You can't successfully with LIPOs I don't know about car batteries (my experience is limited to a charger designed to charge the single battery in my car :slight_smile: )

2) what constitutes charged? I think (but don't know for sure) the voltage hits around 14.4 volts. Do you damage the battery if you keep charging after that point? I don't know.

3) Do you need to limit the charging current in some way (I doubt, it I expect a car battery will take much more than your generator will provide, but I don't know for sure).

There are probably a bunch more I haven't though of as well. You need someone that is experienced in doing what you want to do (charging series connected car batteries) in order to insure you do this safely. Unfortunatly that isn't me.

Need to import smoothiboard from github

$

Hi everyone,

I'm hoping there is a simple fix to this. I'm new to Fritzing and I am trying to import a part. Some one has already done all the work to make a smoothieboard part and post it on Github, trouble is, there is no fpz file to import or open. I was wondering what my options are with regard to this. Unfortunately my googling has turned up precious little in the way of help on this topic. Could anyone tell me how to (or direct me to the instructions for) importing a part that is not in an .fpz/.fzpz/.fzz file format? Any help is appreciated. Thanks in advance.
