This is a Project made with Fritzing, Arduino&Teensyduino. named Venti POV 80HD.
Completed in summer 2018. Thanks for all the help from Fritzing community and PJRC community :slight_smile:

Defined to used in Flow arts, poi or staff spinning, and drawing pictures by Persistence Of Vision (POV)
a 3-part board with a Teensy holder, a touch pad cap, and 2 sides of apa102 LED strips(hard PCB style)
Hardware starring: Fritzing designed PCB boards, Teensy 3.6 development board, Apa102 I.A. RGB LEDs.

I’m no professional and very-unnoticed about any rules in schematics,
I use pads and holes like whatever I like, not sure but they did work.
so if you see any unreasonable design in your sight,
please reply so I can understand and fix them :slight_smile:

for more details about the project see PJRC forum for reference :

https://forum.pjrc.com/threads/53088-Venti-POV-v2-0-80HD

Also the three maded board in the same file :
80HD_2018board.fzz (265.8 KB)

Please focus in the PCB view, I made no effort in other views.

circle: touch pin extended to reach user easily, and worked nice :slight_smile:
USB slot was done by many holes, another slot is for a DC1.3mm plug so I can charge the battery thru.
I use thin wires to separate ground-fill to some shape intended. (this takes long time on ground-filling if your shape was complicated. )

80 apa102 LED strips: 80HD means 80 leds in a High Density of 4LEDs / Cm. Some hard time wiring and soldering. The back of the board is extra pads for extra possible places for battery connections. Carefully connected to ground, but not MOS-drain, so apa102 was not powered without T3.6’s pulling.
The N-mos drain is connected all the way pass the board so every LED gets the same resistance from wiring, and shows same brightness.

holder: with a MOS controller,battery level divider resistors and capacitors for Lithium battery.
I didn’t use all the pins from Teensy 3.6 so not all the pins are placed and soldered. (I’m so lazy)
Also it was better focused with less pins laid.

Hello, I’ve created 35 parts. Lots of them are provided by fritzing with wrong pitch (or maybe different variant), that I had to edit… Hope that will help someone…

Maybe, Most of them are already created, I did not found.
Maybe, most of them you can find also wrong, but I created them comparing with my parts that I work with.

I’m very lazy person. So, BB view of the new parts maybe look dull to you, but I worked till my self-satisfaction.

Please, check the description in the image before use.
I also provided actual picture of some parts…

If there is any error, problem, mistake… Please Let Me Know…

Breadboard scale in FontsAndTemplates scale

Noobiest Noob speaking:

I’m trying to design a new part (for the hell of it). I downloaded Inkscape 0.92, and latest Fritzing 0.9.3. When I read the Breadboard Template from “FontsAnd Templates” into Inkscape the scale seems a bit to small. If I read in other components (like a Feather M0) they seems to appear at the scale I expect, and have used to design my fantastic first component. Attached is an image showing my challenge. Obviously I have screwed up, but after a day of fiddling, I’m stuck.

Would some kind person throw me a line?

New part problems :inkscape & fritzing

@Lineaxe wrote:

Creating a part using inkscape. A short online tutorial told me to move all my objects into , silkscreen, copper1 ,and subgroup copper0. When I did this they all disappeared in inkscape and although Fritzing doesn’t complain about the format , it shows a blank image. I am new to this, and have to learn inkscape and Fritzing better. So I would like to submit the images ,etc for others to quickly check over.

European vs American standards can I change them?

@CABBAGE0896 wrote:

Hello and good morning, brand new Newbie here. Simple question, is there a way to switch from European standards (mm and mils) to American standards like inches and decimal feet? I appreciate any responses, thanks. Another issue I’m trying to solve is with the silkscreen layer more specifically the description of a part after it has been placed. Can they be moved independently of the part itself in the silkscreen? What I’m finding is after placing a part in any view(breadboard,schematic etc.) is the label for the part is far away or turned the wrong way, how can I work with these separate from the part or can I? Thanks again. C

Cannot execute Copper Fill correctly

@JoeAlders wrote:

I cannot execute the “Copper Fill” or “Ground Fill” as I want it.
Why? Simply because, after reading a lot of threads here about Copper Fill/Ground Fill and after a lot of trying and error, still haven’t the foggiest idea to get things done as I want.
In the example I am posting here I have made a ground plate connection using a via at the output of my RIAA equalizer and I simply cannot recall how I did that. In fact I want to place more via’s which are only connected to the ground plate on other places of the circuit so I can experiment with earthing the copper plate by simply solder a wire to one of the common connections of the circuit after the PCB is realized.
Is it possible for somebody here to give me a step by step action how to accomplish this?
Thanks in advance.

Hi,
While I was using fritzing platform, I noticed that the Arduino Nano V3.0 I/O Expansion Adapter Board Shield doesn’t exist. The fact is that I need this board shield in order to construct a diagram for my circuit. Is there anyway to find a .fzp file for this board shield?
Thank you very much.

Hi. I’ve been searching for a part for the Songle SLA-05VDC-SL-C 30A relay. This is a pretty common relay found on Amazon. I have seen the part on a PDF from someone else’s Fritzing schematic, but I cannot find the part for download. Does anyone have this?

Learning Arduino Tutorials

I’ve enjoyed working through the Learning Arduino tutorials, and I’ve learned quite a lot. But I have to say, Episode #1 is TERRIBLE.

For starters, voltage is not a “speed” – it’s a FORCE, as in Electromotive Force (EMF). Second, Stephan shows streams of electrons of various strengths (currents) but never says WHY one stream is flowing faster than another.

The difference, of course, is RESISTANCE, something he never mentions in the video.

A much better analogy is the one about water flowing through a pipe. Voltage is analogous to pressure, current to flow rate. Resistance is determined by the diameter of the pipe (or perhaps a restriction, like a valve that can be adjusted.

Please consider re-doing this one video. The others are all so good, it’s a shame #1 is so bad.
