Small Transformer 14x19x15h
I wouldn’t mind a real scope, because the DSO138 certainly comes in handy, it’s just that I would never use it enough to justify the price. Oddly enough I don’t use the waves that much, more the...

Searching for ST7735B - 128x160 TFT LCD Display part
Anyone done this display ? It is very similar to the AdaFruit 2.0 except that it is 8 instead of 9 pins and slightly smaller. I tried editing the AdaFruit 2.0 but I am clueless with the parts editor

Searching for ST7735B - 128x160 TFT LCD Display part
There doesn’t seem to be one, but because (at least for me) it is an easy mod this should do what you need. As always if you are making a PCB you need to check the footprint (the mechanical drawing I...

Peter, Thank you for the detail. I have added it to my board.

That is an interesting option. Happy to see only 1 chip on there, looks like a diode. Was thinking I needed some caps on there guess not.

I am making an Arduino shield of sorts. It is almost ready but I need a couple parts to finish it off. Is there parts out there for the Arduino headers with the long pins and female headers? Same for...

In the core parts bin near the bottom with the label connection the first icon (a single .1 connector) is what you want. If you drag that in to a view then Inspector (the lower right window) will let...

Thank you. I wish editing parts was as easy for me. Trying to mod the closest AdaFruit Part proved disaterous. BTW there are several TFT’s with this footprint or one very close. One thing people...

Does an Arduino Uno Mega Shield SD Card ICSP SPI Exists Already?
I often use sdCard adapters on Arduino (UNO, Nano, and Atmel chips on a PCB or Breadboard). I just finished an indoor lap counter (to count laps I jog in the house 14 laps = 1/4 Mile… LOL) A summary...

Well my PCB prototype is complete! If the SD card doesn’t work I’ll swap it out for the pre-done ones that are mentioned here. It would probably make my PCB single sided too. Hmmm… Now to get the...

Xenon Timing Light
Sorry, back again I made this circuit based on a vid from The Signal Path because it’s simple. The circuit has to be simple, cheap, with easy to find parts. When I apply 5V - voltage doesn’t makes...

I must say I don’t really understand how that circuit works. It looks like it makes a half wave input which could be why the output is so low. I have done a lot of work with Nixie tubes and VFD...

I’ll have to read all that, but this is from a disposable camera so must be the simplest. It’s explained here.

Could it possibly be that your text equipment is just too much of a load? Nixie tubes only run at 2 - 5ma. It could also be that you need the neon indicator tube as part of the oscillating circuit....

Old_Grey: The only transformers I could find were in old transistor radios, so is the transformer wrong? I did some Googling and it said the only way to work out unknown transformers is test and...

So that’s how you work out transformers. This is 1-ish ohm to 14-ish ohms - my DMM doesn’t seam that accurate - but my cheap Ebay transistor checker shows 3.2mH to 32.8mH which is close to 10:1. It’s...

Actually you can’t really use the resistance to determine the windings. Both windings are most likely wound with different wires (thicker for low voltage side, the thinnest possible on secondary)....
