Tested it on my spectrum analyzer and it's working. Mine came with two of the same cables instead of one of each, but that's minor.

Feels pretty solid and well put together. Scans barcodes and QR codes nicely, even when they're printed small.

A very good EL for the price. The USB is a bit odd, it needs a very non-standard male to male USB cable. You'll need drivers for the CH340G installed on your computer. The software is a bit rough and ready and I couldn't find a way of getting it o produce a log file while discharging a battery. Fortunately the SCP is pretty easy to code up. Build quality is decent, accuracy seems decent. Overall a pretty good buy.

A super little RF synth board. There are open source Arduino sketches to build it into a settable generator. Note that at low frequencies the output is a square wave. The on board 25MHz oscillator module is a cheapie which affects overall performance. In order to use the 10MHz input (via the SMA connector next to the oscillator) you'll need to remove a link resistor.

Samuel I'll have to measure...I use it for battery discharge so it's not critical for me. If you're based in Cape Town your can pop in and take a look.

A very simple but effective tool. It will easily allow you to make precise markings for woodwork etc. You can't go wrong with the clear engraved markings and slots for your pencil. Resolution is down to 0.25mm.

A very nice little unit. It worked out of the box and I like the feature where it goes to sleep when in the cradle.

Samuel Mine was also rubbish quality. Loose screws, poor quality mounting hardware and really dreadfully bad soldering on the underside of the PCB. In addition it has input fuses rated for 4*30A which means that the 12V version is only good for 1440W. Maybe your fuses popped and you can replace them. You'll need to be able to solder though.

Arrived yesterday open the box found some screws are loose then I fasten myself. Keen to try it out for my 2400 watt kettle to boil water...2 liter water took me 10 mins nearly 80 degree then suddenly power out. The inverter is hot and I assume it’s over heat protection. Wait till cool down and try to turn it on but no luck no response nothing !! It’s dead. I wouldn’t recommend it and waste my time. Definitely request for refund for sure Not cheap but you know...ruxxish. Will rather expensive but reliable one.

I bought this on Black Friday so I got an especially good price. It's a lovely set of imperial step drills, nicely made, a comprehensive set of sizes, all clearly marked and in a very nice little case.

This is an amazing little scale. It has 1/100th gram resolution and goes up to 300 grams. This is a full 15 bits of resolution which is incredible for $6.28 There's more good news: I have run a simple linearity test on the scale and it is superb. I weighed a screw which was 0.81 grams. I then took the screw off and put 200 grams on the scale. I used the tare function to set the scale to zero. Then I put the screw back on and it weighted in at 0.82 grams. This is excellent!

A very nice little set. It can do much smaller screws than the sets that are common in our hardware shops which is a bonus if you use small machine screws.

Very useful because you can apply it precisely and only make it set with UV light once it is perfect. Very clear optically.
