I've been smoking for over 20 years, but this was my first time trying an e-cigarette. Read a longtime smoker's impressions below.

While browsing various reviews, including flashlight reviews, I realized that I don't have a single flashlight at home. Well, what I do have could only loosely be called a flashlight. So I decided to order a couple of inexpensive flashlights; this is a review of the first one. In short, it could have been better.

The first time I saw this mini computer, I knew I wanted one too. Read on for the rest of the story.

My wife had a little phone that worked great and did everything she needed, but then it suddenly started acting up. She didn't want to buy a new one—she'd already gotten used to this one. Besides, it had recently been fitted with a higher-capacity battery, so it lasted longer and was even more comfortable to hold. So we decided to fix it. More after the jump.

At work, we have quite a few portable radios, powered by Ni-MH batteries. They charge them any old way, so the batteries fail quickly. Lithium batteries were ordered as replacements. If you're interested, read on after the break.

At the beginning of last month, I reviewed the 1602 display and also talked about one way to use it. But as they say, appetite comes with eating, and I wanted to make a version of this device with a larger 2004 display. But the display model isn't the only difference. If you're interested, read on.

While I work on a short but fairly complex review, I decided to take a little break and write about a Bluetooth-UART module. Not long ago, I did a series of reviews devoted to one of the radio amateur's essential tools: the bench power supply. By the time I was writing the review of the USB-RS232 adapter, I was already planning to call it a day. But then I thought: why use wires to control a power supply in the 21st century? Read on for the rest of this experiment.
