Monoprice 44220 Benchtop CNC Router Kit review – DIY engraving

monoprice CNC 44220 02

REVIEW – I remember reading a Time magazine article in the 1980s about computer numerical control (CNC) manufacturing. I never thought decades later, I’d be able to have that kind of power at home in a DIY kit from Monoprice, of all places. I also never thought I’d burn three days trying to figure out […]

Quntis 82ft 1000 LED string lights review – Light up your holidays

qunits 82ft LED 01

REVIEW – Several years ago, I strung together lights along my backyard fence with varying results. One strand wasn’t really for outdoor use and failed. The next  strand I tried required me to daisy chain several together, and eventually failed. As luck would have it, I got my hands on the Quntis 82ft (25m) string

iDOO Electric Compressed Air Duster and Vacuum review – no more canned air

iDOO electric duster vac 05

REVIEW – I stopped buying canned air for dusting because at $5 to $10 per can, it just didn’t make sense. I have an air compressor in the garage, and a small rubber bulb for dusting small things like camera parts. I think the iDOO electric compressed air duster and vacuum might fit nicely in

Slimca Here rechargeable tracking card review – wafer thin device tracking

slimca here 03

CROWDFUNDING REVIEW – When Apple Airtags were introduced in 2021, I immediately thought of all the usual things I might lose. Unfortunately, the Mentos candy-shaped Airtag doesn’t slip well into a wallet. The Slimca Here is a credit card-sized tracker compatible with Apple’s “Find My” function and is USB-C rechargeable. What is it? The Slimca

EPOS Impact 1000 series headset review – Designed for the Open Office

EPOS IMPACT 1000 series 12

REVIEW – My interest in computer headsets has risen quite a bit since the era of desktop videoconferencing has become mainstream. Wearing a headset can be tiresome, and sound quality varies all over the place. The EPOS IMPACT 1000 series headset boasts a design to reduce wearer fatigue. What is it? The EPOS IMPACT 1000

WaterField Travel Toiletry Bag review – Tip top tiny tote

waterfield TTB 09

REVIEW – The first toiletry travel bag I ever had was from the early 1980s. It was a vinyl zip up bag that came with my Remington shaver. It eventually cracked and dissolved from years of use and exposure to DEET bug repellent. I’m not quite as adventurous now but the WaterField Travel Toiletry Bag

Dangbei Mars 1080p full HD projector review – Sharp and silent

dangbei mars 03

REVIEW – I’ve seen many projectors online that all claim bright images, “smart” TV functions, and quiet operation. I tend not to believe any of them since there are so many to choose from, and companies I’ve never heard of! Plus, I already had a trusty no-frills Epson projector that was pretty cheap at the

Lockly Smart Safe review – One clever box

Lockly Smart Safe 12

REVIEW – During my time with the FBI, I remember the keycard access controllers were combined with the incredibly clever Hirsch ScramblePads. Think of your regular ATM keypad, but the numbers underneath the buttons change each time you enter your code. This increases security since it’s harder to “crack” the code just by fingerprint smudges

TOZO OpenReal True Wireless Earbuds review – Open ear comfort

tozo openreal true 10

REVIEW – I cannot wear “in ear” headphones. They just hurt too much! I even avoid the popular Apple AirPods. Besides bone conduction and traditional over-the-ear headphones, there’s this interesting middle ground of “air condition” headphones that sit just outside your ear. What is it? The TOZO OpenReal True Wireless Earbuds are a stereo, Bluetooth

Typhur InstaProbe kitchen thermometer review – Way faster than the rest?

Typhur InstaProbe 01

REVIEW – I cook with thermometers all the time because I don’t trust my skills. One day, the sleek Typhur InstaProbe thermometer popped up in my social media feeds. It LOOKS pretty neat but is it good enough to dethrone my reliable Thermoworks Thermapen One? What is it? The Typhur InstaProbe is a battery-operated thermometer

Keychron K1 Pro wireless mechanical keyboard – low sound, low profile

keychron k1pro 01

REVIEW – I’ve often looked for a nice keyboard that will work with my Mac. Yes, all keyboards work fine, but I prefer those with the MacOS specific keys. I also prefer the smaller tenkeyless design as they take up less room. This time, I got to try the Keychron K1 Pro mechanical keyboard. What

Helinox Umbrella One review – Fighting off the rain and sun

Helinox umbrella one 12

REVIEW – I live in California where we’ve been in a mega-drought for many years. The idea of having an umbrella seems rather pointless. Of course, this winter has been abnormally wet for some reason! Where can I find a decent umbrella I might not want to lose, and won’t fall apart after two days?

Shargeek Retro 67 USB-C charger review – Old school Mac charm

shargeek retro67 charger 01

REVIEW – The folks at Shargeek have been on a roll lately. It wasn’t that long ago that the Retro 35W Mac-shaped charger charmed its way into the world, but the Retro 67 takes the nerd factor up a few notches with three USB-C ports and a green phosphor screen inspired display with some “Matrix”
