· 1 comment · 800 words · Viewed ~2,831 times


Close up on camera lens, sensor, and IR LEDs

The good folk at Ailipu Technology have sent me a fist-sized USB camera to review. This is a cheap and simple way to get external video into a home server like a Raspberry Pi. This is the, slightly cumbersomely named, elp-usb100w05mt-dl36. What's in the box? The USB cable is around 5 metres long, and is wired into the camera. Four screws and rawlplugs are also included. Why? Because there…

The good folk at Sonoff have sent me yet another gadget to review. This is a slightly curious device - an IP to 433MHz remote. This allows a smartphone to control smarthome gadgets which usually require an RF remote control. It costs £8 plus postage direct from Itead. This is similar to an Infrared device I reviewed a few years ago. It's a cute little box, small and light enough to hide away …

I don't think the people who sent me this touchscreen are going to be very happy with this review. But that's the peril of asking bloggers to assess your kit, isn't it? The good folks at Sonoff have sent me a review unit of their "7.0" Nextion Enhanced HMI Capacitive Touch Display with Enclosure". A USB powered touchscreen - with a range of hackable goodies. It's a device which sadly fails…

I've been sent a couple of Sonoff smarthome gadgets. You can read my review of the S20 WiFi plug socket and the POW in line power controller. Here's a video of me controlling them from my Amazon Alexa: The latency seems a little slow - hard to tell if that's Amazon only relying on US data centres for Alexa skills, or the connection to my home. Once set up, it works well. Oh... but…

A schematic of a smart plug.

The good folks at Sonoff have sent me a bunch of kit to review. First up, the S20 WiFi Plug - an easy way to retrofit IoT smarts to your existing appliances. This fills the same niche as the Belkin WeMo but with one crucial difference - it's about half the price. Direct from Sonoff it's US$13 - from Amazon UK the smartplug is £15. The cost of the WeMo is £40. How does it compare to the B…

Earlier this year, I reviewed the Chipolo Bluetooth Tracker. It's a small fob which you can attach to your keys & bag, stuff in a wallet, or slip in a pocket. Push a button on your phone and, if the Chipolo is within 60 metres, it starts beeping loudly. Six months is a long time in technology, and Chipolo have just released the Chipolo Plus. They've sent me one for free to review. Set your…
