I bought this cheap IP camera and want to reprogram the firmware to include a web gui. Installing a UART is like a keyboard and monitor your computer. You will need a USB TTL adapter. Only connect the ground TX and RX pin. Only connect the 3.3V VCC if your connecting a JTAG. UART and a serial protocol and not a JTAG. A JTAG is used to communicate directly with the flash chip. https://www.amazon.com/gp/product/B00IJXZQ7C/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00IJXZQ7C&linkId=5322b18ffa078b3eac68b3d2b6e9bfbc

Bummer I have to make this video, The cost of hardware and power does not make sense in Southern California. I've been CPU mining AVN and RTM for about 2-3 months. I had previously mined Monero for about a year and non of it is profitable. My power company SCE has brutal rates. Everything is stupid and backwards in California. https://www.amazon.com/gp/product/B09BQNYMMM/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B09BQNYMMM&linkId=f6d82fef4e941e33dc5a5d1a00f4ef1b https://www.amazon.com/gp/product/B08GKGS197/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B08GKGS197&linkId=0a2b9886ff7d031a963c21e40f8ab9d6

I'm been looking at these on Amazon for about year. I already had a small metric dial indicator. I've been scouring the internet looking for a reasonably priced full size CNC.

My nightvision IR board got fried during my POE board repair. There is typically two thing that go wrong with night vision. One is the IR board and the other is the Lens shutter. https://www.amazon.com/gp/product/B081SF2RMS/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B081SF2RMS&linkId=01b71ab4f1af9df09e11717d8a0e5172

One I noticed one my camera went offline. I went outside and noticed the IR LED's were still lit. I decided to take the camera apart and troubleshoot. My POE board had a blown capacitor.

My customer brought me his old iMac to get running again. The the browser and root certificates were out of date preventing the computer from going to most websites.

I was looking for a faster larger laptop to compile Linux images for an openwrt project. This laptop is nice. Very large screen with all the bells and whistles. Its also has a dedicated Nvidia GPU with 2GB of RAM. I upgraded to 16GB of RAM, 500GB SSD and dual band wifi card.

I wanted to change the bootloader on my openwrt board to boot from msata or micro sd card. I'm getting a lot more familiar with this tiny foot print SOC Linux. I have a few projects I'm working on.

I've been fixing Makita batteries for about 5 years. I learned a few things along the way. If your battery charger rejects the battery 3 times it will permanently disable the battery pack. The batteries BCM (Battery Control Modules) is a parasitic draw and will eventually discharge your batteries. In my case the cells were fine but the battery was rejected because the voltage was too low. The battery does not know if its bad cell or heavily discharged. You will need an 18V dummy charger to bring it up. I lost batteries in the past by not knowing the 3 rejection rule.
