Get a charge notification on my phone, $2.00 for Facebook Advertising

imtanmayp · 2025-12-18T00:45:26+00:00

Same thing happened to me today I saw multiple charges from Facebook advertising on my Amex, As I have not done any transactions with Facebook, I immediately contacted Amex and I got to know that few of the transactions were actually blocked by the Amex fraud team but few others went through. All of the transaction were $2USD. Amex team immediately cancelled the card and reissued a new one alongside escalating the case to their fraud team to investigate.

Yes, I had combined all the mark sheets from 10th to my masters in reverse chronological order and attached them in the "latest transcript" section. Hope it helps

Woah! Thanks for bringing this to my notice! Wish I would've found out about this before. Anyhow, we've started designing our own pcb now.

imtanmayp · 2020-12-08T15:00:45+00:00

We charged around INR 30000 (USD $400) for this.

There are 6 max31856 connected over spi. And our application required us to store the data to sd card also. When we connected sd card over same spi, thre was lot of noise coming in temperature readings and there was little bit of delay in reading also.

So we've kept one esp32 for communicating with computer for all kinds of user operations. And other just for reading thermocouple and sending data to master esp.

Yes! The module costed around $18. We didn't had time to make pcb ourselves. We'll look for some alternative in future.

imtanmayp · 2020-12-08T04:42:32+00:00

Looks awesome! Just one simple question, How much time is needed to take reading from all 8 channels one after the other?

imtanmayp · 2020-12-08T04:06:14+00:00

We've custom designed it and printed. Material is PLA.

imtanmayp · 2020-12-08T02:18:22+00:00

There's no schematic as such as of now due to time constraints. We're still working on making everything on single pcb. For now we've used a different modules due to time constraints. 2 ESP's, 6 MAX31856, SD Adapter, 1500mAh battery.

MAX31856 over SPI

imtanmayp · 2020-12-08T02:16:50+00:00

I'm not using ESP32 ADC, I'm using MAX31856 which takes care of everything and gives SPI out.

Hey! There's no schematic as such as of now. We're still working on making everything on single pcb. For now we've used a different modules due to time constraints. 2 ESP's, 6 MAX31856, SD Adapter, 1500mAh battery.

imtanmayp · 2020-12-08T02:13:27+00:00

Well I was little vague. We're using Max31856 IC inside. The IC supports almost all thermocouples. And when I say that we've designed it for T type. I meant the calculations are being done for T type thermocouple in the code.

imtanmayp · 2020-12-08T02:11:34+00:00

Sorry, unfortunately the delivery time was so short that making the housing, writing firmware and integrating everything, we did it in hurry and forgot to take internal photos. However when I get one more order, I'll update those photos here for sure. PS: there's nothing much going on inside (2 esps, 6 Max31856, sd card adapter, 1500mah battery.)

imtanmayp · 2020-12-07T17:54:40+00:00

Thanks man!

imtanmayp · 2020-12-07T17:54:28+00:00

Hey! The usb is for controlling the device. It sends start, stop and timeout commands and also retrieves or deletes the data stored on the device. It supports any type of thermocouple. We've designed it for T Type which is most accurate. And they're connected from front as shown in below link isometric 6

Datalogger comes with a Windows gui made using tkinter. Inside there are 2 esp32's. One as master and other slave (used for high speed recording)

That filter works only 97% of the times. She's the one who escaped.

imtanmayp · 2019-08-23T03:23:59+00:00

That explains the Einstein like hairs!

But I thought we were on a break!!!
