Don’t see one in a google search, unfortunately also don’t see a mechanical drawing or even a pinout list at a quick glance. It should be relatively easy to modify one of the existing parts with...

is there an easy way to get a (generic) IC with “oblong” / rectangular - non round - through the hole pads to enable routing of small wires between the pads? Currently I need ICs 300mil with 28pins...

Generic ICs with oblong/rectangular pads?
noiasca: is there an easy way to get a (generic) IC with “oblong” / rectangular - non round - through the hole pads to enable routing of small wires between the pads? Depends on your definition of...

thanks Peter. I tried my best and did the 3 parts. In the gerber viewer the parts are looking ok so far. I will let produce a test pcb and if the parts are ok I’ll publish them.

You want to look at the drill.txt file from the gerber output and check the drill sizes are correct. For ICs they are usually .035 in I think. If you want to post the parts I can have a look for...

BME / BMP 280 sensor
Not bad, but a few problems: schematic svg: is missing the schematic layerId none of the connectorxterminal labels are correct. 0 and 1 are still rect and 2 and 3 are labeled 4 and 5. That causes the...

Again not bad, but a few problems: bb again missing the layerId pcb the hole sizes are wrong, they should be 0.035in for an IC yours are 0.027222 according to the gerber output. fpz file changed label...

hello, none of the text with OCRA font is visible on my breadboard part. if i convert it into path it’s ok what’s the reason ? here’s the inkscape svg...

First thing to try is edit the svg with a text editor and remove the px from the font-size (I usually just delete all the px). There is a quirk in Fritzing where it will set the font size to 0 if you...

thank you very-much for your answer removing the “px” solves the problem ! great

Dear All, I am working on a project which checks the pressure sensor in washing machine that is ok or nok. First of all, let me explain how a pressure sensor works. It is a circuit which uses pressure...

You could make a simple RC filter (resistor and capacitor) to convert the pulses to a smooth DC voltage which could be read by an analog to digital converter (ADC) on most microcontrollers like...

Here’s an example of an RC filter I found on circuitlab. https://www.circuitlab.com/editor/#?id=zhq9j8 In your case your sensor is the source of the square wave labelled “V1” and you would read the...

I do not believe an RC filter will give you what you need. A phase-locked loop is a better solution. See the circuit: CD4046. What is the frequency output of your transducer?
