SDR

Episode 1659

Jerry from Hatfield, VA

Jerry is into ham radios and he wants to know if a software-driven radio is a way to go. Leo says that everyone is going with software-driven radio design now, and a lot of Chinese companies have flooded the market with inexpensive models. SDR USB dongles can even turn a computer into ham radio. But he's frustrated because it doesn't save his information or channels and he has to reacquire everything. Leo says that sounds like a flaw in its design. It could also require a driver for that USB dongle. Or, turn on the computer. Let is power-up, and then plug it in.

The Giz Wiz and the Mobile Disco

Dick

Episode 1648

Dickie D is back with Smart Phone Disco Lights! It doesn't rotate, but the flashing colorful disco lights inside give that illusion. It can be powered by your smartphone, an external battery charger, or even plugged into a computer. Once plugged into a power source it lights up to the rhythm of your music or even your voice! As you'll see in the video it does give off quite a bit of light for something that small. On Amazon, they are only $12.00 for three of them! But wait, there's more. Each one of the three came with adapters for micro-USB, USB-C and a lightning connector.

Is there a self powered laptop cooler?

FEMOR Laptop Cooling Pad

Episode 1631

Nooru from Mission Viejo, California

Nooru has a laptop that is overheating. Will a cooling pad work and is there one that is self-powered? Leo says that most of them are powered by the USB port in your laptop. But will also plug into a USB adapter that plugs into the wall. Everyone who has a mobile phone has a USB adapter AC plug. So all you need is a cable long enough to do it. Another option is to use a portable USB power bank. You can then just attach that to the back of your cooler and it'll run for days. Any particular brand? Leo says no. They're all pretty much made by the same company in China.

Why am I getting a device error running Windows update?

Windows Error :(

Episode 1619

Dave from Burbank, CA

Dave upgraded his hard drive to an SSD for his laptop and then used Windows 10 and the media creation tool to install. He got a message failure - "no device drivers are found." Leo says that for future reference, use a USB thumb drive and change the boot order to your USB key. And install Windows. It's really easy. Leo suspects that since Dave had a USB external drive plugged in, the error occurred. Leo recommends unplugging everything except a keyboard and mouse, then run the install. Once Windows is up and running, you can add external devices and Windows will install it.
