Cricut Maker, has anyone used to make stencils?

I was working on it over the weekend and was able to make both a positive and negative image (at the same time) of the PCB layout I’m considering etching on a copper clad FRP board.

One has the trace pattern left in vinyl to be transferred to the copper board. The other has the opening like the SMD stencil shown in the video which will require filling in with ink marker or some other suitable masking agent to protect the copper.

I also have the vinyl backing paper I’m going to try and use with a laser printer to attempt the toner transfer method with an iron just for comparison of the results.

Hello Old Grey,
I know this is an old post, but I just bought a couple of these and found some errors.

  1. The board is .1" too wide the distance between pin 31 (mislabeled BTW) and 47 should be 1.3" not 1.4"
  2. I added the 6 GND pins in the upper left, and the ICSP pins on the right
  3. Bussed all of the added pins where needed MOSI, MISO, SCK etc

I have made a board from this part and it worked for me.

Here is the updated part with revised breadboard, schematic and PCB views:

If you have one and actually measured it, yours must be right.

I had nothing but pics on Goo and it looked like 15 x 21 pins, and when I saw an EasyEDA drawing showing 38 x 54 that’s the one I picked.

Hello World,

I need part Screw Terminal 5mm pitch in 2 and 3 wire. I’ve googled but I have not find it.

The integrated version in Fritzing does not have the good bulk on the PCB.

This version is largely used.

SparkFun 8432 and SparkFun 8433

Here is the Datasheet

Someone have already made the part ?

Thank you In advance

I read the how-to and I tried. But drawing is not really something I can do. And especially for which I have patience :wink:

So thanks for your work and time

Me parece una excelente iniciativa.

Por cierto ¿alguien sabe si hay alguna forma de colaborar con el desarrollo de Fritzing?

Your part has a variety of problems (not being on the grid in breadboard for starters). Do you have a url to the mechanical drawing of the board for dimensions and pin spaceing? If so I’ll look at fixing your part up.

What’s “good bulk” ?

For PCB all you need is 5mm pitch header with enough room around it so it doesn’t hit anything, so any screw terminal should be good enough if you know the size difference.

Looking for a On-Off-On switch

Unfortunately none of the switches I could find in Fritzing match the OP’s requirement. It is a SPDTCO or DPDTCO the OP wants (the CO standing for Centre Off), and there are none in Fritzing.

Looking for a On-Off-On switch

This may help…

First: You can simply use any current part that has 3 pads at the pitch you need for your switch.

Second: I made several for some of my Arduino gizmo’s - The micro-switch slide switch has 3 small pads (on-off-on).

Third: The Blue Toggle is on-off-on. The only thing different between a Toggle and a Slide is the Graphic for the BreadBoard. Thus, you can use it for a Slide Switch if you can live with the BreadBoard graphic (or change it…)

Lastly: Just to complete the picture, the third uses only two positions on a on-off-on slide switch.

Parts update on windows not working

Unfortunately I don’t think there is a quick fix for this. It looks to me that the problem is likely that the libgit2 library in the Windows zip file is too old and none of the cyphers it supports are supported by github anymore and the ssh connection fails. I can’t be sure because I don’t have a copy of the original libgit2 that shipped with 9.3b and a current version works fine (other than problems with some new parts). So it looks like parts update needs to be done manually by importing the latest repo in to fritzing-parts in the code directory (it appears to load just fine without rebuilding the database). On the plus side I have managed to figure out how to get a Windows build environment running so hopefully soon you should be able to do a build from source to make a version that will both fix bugs and update parts.

Ground fill dashed lines

I have a question about Ground Fill.
Here is my circuit before ground fill. The 19 missing connections are all GND and all on the yellow (TOP) side.:

54%20AM

Then I select Ground FIll (Top).

58%20AM
Screen Shot 2018-09-02 at 9.55.58 AM.png539x1091 145 KB

It seems to have done a beautiful job. The ground fill bridges at each pad work better if there is not an existing trace to ground. However, all of the dashed lines indicating unrouted nets remain, and it still reports “19 connections still be routed”. However, a visual check of the ground plane reveals all ground pads are connected to the ground plane.

What am I doing wrong?

I’ve done a new installation of 0.9.3 twice and the parts search facility does not appear. I’ve attached an image of the default installation after automatic upgrading of the parts.

I’ve searched the forums and I only get 3 year old closed forum posts.

Making a small +5V copper-fill area

I wanted to build a roughly triangular area copper-filled, tied to net +5V.
Here is a portion of the schematic:

59%20PM

I wanted to tie the +5 on U2 (Vout), C17, and C18 on the YELLOW side together with a fairly large pad, and connect this to the RGB LEDs with a +5V bus on the ORANGE side of the board.

I accomplished this with 6 vias. Here is the PCB view, from the TOP:

02%20PM
Screen Shot 2018-09-02 at 5.08.02 PM.png429x643 74.7 KB

First I added the 5 intermediate Vias. Then I connected U2, C17 and C18 (all on the YELLOW side) with 48mil traces to 3 Vias. And interconnected those also to two other Vias.

Then I drew this triangular fill area, by connecting the 6 Vias to each other with 100mill traces.
The result is pretty good! This might be overkill, however, since all the failures in my previous board layout were power and voltage-drop related, a little overkill is good.

Next, I will ground-fill the top (YELLOW) side; and copper-fill the rest of the bottom (ORANGE) side.
