December 24, 2017 Peter ScargillGeneral109 Comments on Why has Peter been so quiet?

I’m posting this entry on behalf of Peter (my name is Jonathan – a long time friend of Peter who he has mentioned a few times in the blog). Peter says: “Unfortunately last Friday (December 15th) I was taken ill and find myself in hospital. While I am making a…

Another Very Busy Week

December 14, 2017December 15, 2017 Peter ScargillB35T+, Mix 2, owon, Tarantula33 Comments on Another Very Busy Week

I’ve been working on all sorts of projects this week, some more successful than others. I have a new Owon digital Bluetooth multimeter, I’ve done the first of a pair of videos on the Tarantula 3d printer, got my new Doogee Mix 2 smartphone – but first….

ESP8266 Mesh Experiment

December 11, 2017December 11, 2017 Peter ScargillESP8266 mesh32 Comments on ESP8266 Mesh Experiment

In case anyone else (like me) has been sitting on the shelf over this one – and would like to have a go at an ESP8266 mesh… we’ve been having a play. Regular readers may recall I wasted the better part of a year with those AWFUL NRG24L01 boards trying…

Odrvm 4K Action Camera

December 9, 2017December 11, 2017 Peter ScargillODVRM18 Comments on Odrvm 4K Action Camera

Slightly out of the normal, I’ll grant you but I thought this was worth doing a short piece on because of an alternative use for this camera. So what we have here is the Odrvm 4K Action Camera, which comes as a complete kit, in my case from Amazon. Here’s…

SI5351 Clock Generator

December 8, 2017December 10, 2017 Peter Scargillclock generator6 Comments on SI5351 Clock Generator

A short while ago I put together a little poor-person’s signal generator (or signal generator for people who only use them once a year). It is currently waiting for me to drill a tiny box to put it in. Meanwhile of course I’ve taken possession of a FeelTech function generator…

December 6, 2017December 6, 2017 Peter Scargill4D Sysyems, IOD-0926 Comments on IoD-09 Display from 4D Systems

You may recall some time ago I reviewed some displays from 4D Systems – using an ESP8266 together with a touch display – and very nice too. Well, the company just sent me one of the new IOD-09 displays and it is the cutest thing you’ve ever seen. You will…

FeelTech FY6600 Waveform Generator

December 5, 2017December 6, 2017 Peter ScargillFeeltech, FY6600, signal generator, Waveform Generator25 Comments on FeelTech FY6600 Waveform Generator

Regular readers will know we just looked at a DIY signal generator able to generate sine, triangle and square waves. Breadboard, wires, you name it…  Well, this is NOTHING like that.  If the simple DIY generator of a previous blog is not to your liking you might want to consider…

VL53LOX Distance Measurement

December 5, 2017 Peter ScargillVL53LOX16 Comments on VL53LOX Distance Measurement

The VL53LOX usually comes as a tiny board complete with regulator and is an I2c device capable of measuring short distances.  I thought I’d put it to the test. The proper description which sounds very impressive is “Time of Flight (ToF) Laser ranging Sensor” – really?   Well, let’s see what…

Boxes Galore

December 4, 2017 Peter ScargillGeneral38 Comments on Boxes Galore

Nothing special – just boxes. Those with working 3D printers please ignore me. For the rest… I just took delivery of 20 boxes at less than 50p each and I think this is the best box purchase I’ve ever made – got them from Banggood though I’m sure you can…

ZeroPlus Logic Cube

December 4, 2017December 6, 2017 Peter ScargillLap-C, ZeroPlus7 Comments on ZeroPlus Logic Cube

I recently took a look at the ZeroPlus Arduino Starter Kit – well, this logic analyser is not a starter version! This particular model, the Lap-C 322000 has 32 channels  and a bandwidth of 75Mhz. It has 64Mb memory, 2Mbit per-channel depth and is the top of the line in…

Arduino for Beginners

December 3, 2017December 3, 2017 Peter ScargillZeroPlus26 Comments on Arduino for Beginners

We rarely cover projects for beginners in the blog and I guess that’s because most of the people I know who are into technology have been there for a while.  But as I found out when I first started getting into Linux a couple of years ago, it is awfully…

DPH5005 Power Supply

December 2, 2017December 2, 2017 Peter Scargillpower supplies, ruideng27 Comments on DPH5005 Power Supply

Ruideng just sent me their latest power supply and case… or rather, the kit. The control board is assembled as is the display board. You get case, fan, switch, fan PSU and bags of nuts, bolts, washers and wire. What could possibly go wrong?

You may recall my blog entry about my “universal peripheral” – using the little Arduino Nano or similar clones with an ESP8266 – with the former providing GPIO via an I2c connection. Well, that led me to getting this little number from Banggood – the Wemos Atmega + WiFi R2…

AD584 Precision Reference

I’ve been waiting for this little item for some time now… and today it turned up – a very neat Perspex box that requires micro-usb – and which gives out on demand (button press) 2,5v, 5.0v, 7.5v and 10v. Accuracy? It is hand-written on the back. The unit outputs the…
