Pi Zero Gadget Mode and WMI python

Long story short, I'll skip the use case to keep this simple. I want to use a pi zero in gadget mode to connect it as a device to a windows 10 machine and utilise WMI to read information from the windows machine and print it to console. import wmi_client_wrapper as wmi wmic = wmi.WmiClientWrapper( u...

Re: Advice on controlling a heating element?

solid state allows for pulse-statting your heating device unless it is light based without wearing the mechanical side of a standard relay. this benefits from regularly pulsing the electricity on & off to "drip feed" heat, rather than having a sine wave of low peak-switch on & high peak - switch off...

DIY: Wire stripper & equipment wire dispenser box

Hi, though I would share my dispenser box for equipment wire. Trying to keep my ever more complex wiring clean I've adopted colour coding & custom size prototype wiring. To this end I ordered some spools of wire but I was unhappy with how untidy it was keeping them & making then easily accessible. S...

recommend a crimp?

can anyone recommend a suitable crimp for these: http://cpc.farnell.com/pro-power/2010-2041/latch-housing-crimp-type-2mm-4way/dp/CN18821?ost=CN18821 Received a bunch of PCB headers & the female housing from someone else and I can put them to use if I can get the right crimps but between the standard...

Re: wireless set of GPIO - using ESP8266

I did consider these, but experience of existing remote / lamp units of these has been they can be triggered too easily from external sources. another option is because my pi will be web serving an intranet interface anyway, I simply have a wireless arduino read output pin status from the server & u...

Re: That PI2 unboxing: Unmistakable Odor of fried circuitry?

I received a parcel from cpc farnell on Tuesday which included a PI 2 and a few bits n bobs and I noticed the inside of the box reeks & the parts contained inside all faintly smell similar.

Re: Learning electronics, for smart people.

from your description of you, I am very similar. programmer & DB admin at heart for my job now, I'm not slow on the uptake unless I am tired/hungry & when I was young had a 250-in-1 electronic project lab but that was quite some time ago and much of what I learned about actual electronics forgotten....

Re: recommended bits n bobs

just thought I would come back to this post some months down the line as to how its going. Since making this post, I have been to The Range (twice) to buy some handy storage boxes for everything! So lets see. first up I now own a 5U server that I have 3 pi B+ units connecting to my library of digita...

wireless set of GPIO - using ESP8266

good day everyone, I've been working on a project for a few months and had a feature creep happen on me - the ability to add some GPIO wirelessly. To put it as clearly as possible, imagine I'm using my raspberry PI to sense temperature using DS18B20 and based on readings from this, it will trigger v...

Re: Multi-function RS-485 remote sensor

First I apologise, I have done an amount of scan reading last coding etc. but I was hoping you could consolidate into an answer for me: I think I undertsand that this offers input/output by a remote board that can be daisy chained together, but how many inputs/outputs does each board offer? and woul...

Re: MicroSD Cards for B+ ?

I have 2 B+ boards right now for a project, one is using a Toshiba 8GB Class 10 that has 40M read & 10M write minimum speeds. comparing this to the samsung class 4 I got with the noobs bundle it does out perform it - but only just. comparison of these against the Verbatim 8GB class 10 SD I have in t...

Re: recommended bits n bobs

a fair point on the ds18b20.

which is also the reason for the 4k7 resistor, one should plopped between the data & live pins.

recommended bits n bobs

Hi, I have been looking at some hobby kits for just fun and learning about my Pi but find they are all a bit wrong one way or another: old B not B+ cobblers, arduino included and so forth. So I thought I would come here and ask for your opinions on what electronic components you would have in a tool...

Re: Can't decide: RPi or Banana PI?

Just been reading through this as I have as of yesterday received my second rPi for a project. I spent some time looking at alternatives and whilst you got extras here or better there, the overall end-performance would not be noticeable (e.g. you can get a board with give & eSata but as a NAS device...
