This is a quick blog post about using my NooElec SDR for the first time. Back last year I was luckily chosen to roadtest three Molex Antennas Molex 2.4GHz / 5GHz Antenna Kit - Review and that re-kindled my interest in RF work at home. Wanted to have a 'play around' I bought myself a low-cost SDR for fun and it arrived today. It cost me just over £20 (UK) and plugs into the USB port of my computer plus it has a SMA connector for the antenna. I actually made a misjudgment and bo ...

I'm not sure how I've managed this; I've read plenty of articles on controlling stepper motors, stripped stepper motors from old printers to keep them and even bought a nice set of 5x NEMA steppers for making a 3D printer....but I've never actually got around to powering and controlling one. Seeing all the cool things E14 members are making and especially in the Movers and Shakers Project14 I decided I really must get one working. I had a A4988 mini driver board that was for my 3D printe ...
During a discussion over a friend's flat car battery they brought out their 'car battery booster' but it soon became apparent to me that that also wasn't working....and so, like most tinkerers, engineers and makers, it ended up on my bench at home. The unit contained a 12v 13Ah Sealed Lead Acid (SLA) battery, large diameter cables and croc clips for connecting to the discharged car battery, a voltmeter, a light and an external cigarette lighter socket. Charging the booster unit was via ...
This is my test of a Wera bitset. as shown below. 1. Initial Thoughts Without being biased, by knowing Wera is a quality brand, the first thing I noticed when getting the set out of the packaging was its weight. It had a decent amount of weight for the size which equated subliminally to me as 'there's a decent amount of real metal parts in here = it will be strong'. Inspecting the tool I could see it composed of the Zyklop Mini ratchet along the top, one visible ...

[Having mentioned this TV repair on my Status page and getting supportive comments from dixonselvan and genebren, I felt perhaps a blog post would help] Background I was given a nice 22" TV a few years ago as a present. About a year later it stopped working - not even the power light came on. I checked the fuse tha ...
Preface I live in the UK and have never seen a native Firefly or glow worm - I'm not even sure if we get them here. Some years back I visited North Carolina to visit friends and was amazed to see fireflies flashing away in the garden shrubs ...if only I could bring that magic to my garden in summer by making some RGB LED 'fireflies'. My Initial Design Some years back I used the Microchip techsheet AN1606 and the Configurable Logic Cells (CLC) of the PIC16F1509 microcontroller t ...
I bought an ESP-12 (ESP8266) module last year and, after mounting it in a DIL format (via a piece of Veroboard), I never got around to actually using it. A few weeks ago I dug the ESP-12 module out of the drawer, mounted it on my breadboard, added a 3.3v regulator, voltage divider and CD4011 (2x logic gates wired as a non-inverting buffer) and then fiddled away for a few evenings until I got it to boot properly. Satisfied with progress I ordered some more modules...the aim was to control ...
