Voltlog #143 - NSA Style USB Cable GSM Bug/Locator Device
In this video we take a close look at what appears to be a plain simple usb data & charging cable. This is ofcourse not your typical cable but instead a full featured tracking spy device which works over the GSM network. The size, shape and purpose of the device is very similar to what the NSA has in their toolbox and calls it COTTONMOUTH.
Is upgrading to a modern multimeter worth it? In this video, we take a deep dive into the UNI-T UT8805E, a professional-grade benchtop multimeter boasting a 5.5-digit display, tons of features, and connectivity options. We'll explore its accuracy, data logging capabilities, software integration, and more! But is it all sunshine and rainbows? We uncover some potential drawbacks and compare it to older meters to help you decide if the UNI-T UT8805E is the right choice for you.

I'm moving to a new apartment and I have more space for the voltlog lab. Unfortunately I won't be able to upload any videos for 1-2 weeks until I have everything setup.

I started this project to solve a problem I was having and that is constant watering of these two pineapple plants that I’m growing. You know how things work, sometimes you forget to water them and sometimes you are away for a couple of days and there isn’t anyone home to water them.

I understand there has to be some research and testing done for these fuses to meet the safety requirements but can that account for the huge price?

High quality quick turn PCB Services https://www.pcbway.com You might be wondering if there is any way to tell for sure that you’ve got an FTDI FT232R clone. There are at least 2 methods that I know you can use. First one is to install an older version of the driver which FTDI released in 2014, after plugging your fake FTDI depending on the driver version it will either disable the FT232 chip by writing something to it’s internal EEPROM or it will modify it so that it shows a custom alert message over serial instead of your actual data. I don’t like this method, because there is a better, simpler way, you can simply check for the serial number of the FT232 which you can get from the device manager under windows or by using the FT_Prog utility. If your serial number is A50285BI or 00000000 then you most certainly have a fake chip because that is a popular serial number which is written to fake chips. They don’t bother changing the serial number on the fakes, they mostly write the same number or set it to zero.

$2 for 5 PCBs Any Color https://jlcpcb.com I’ve been an Eagle CAD user ever since I designed my first PCB but it was time to let it go and move to something better. Kicad is open source and free of limitations which in my opinion is the only way forward.
