    Circular?

    If I had a requirement (and I do, actually) to design a small circular PCB, which software would allow me the easiest method to do so? I've not (investigated) seen such facilities - is this a case of either not being aware they can ALL do that or that it is only available on some packages?

    Anyone still do this? Anyone had any problems doing it? i.e. compatibility, b*gg*ring up your printer etc?

    Astronomy idea(s)

    Over recent years I've had less opportunity, or inclination, to set up my telescope(s) to view and/or photograph the night skies. This is probably due to the various advances in viewing technology that tends to leave one 're-inventing the wheel' when it comes to viewing or photographing night...

    One for the New Year

    I enjoy watching Youtube videos by The Tech Guy (he repairs hi-end test equipment) and have always admired his variable AC power supply that he often uses to power up equipment that have PSU problems. He did a video showing the innards of this variable AC power supply and despite its relative...

    Interesting PCB production method

    Caught a Youtube video the other night of a PCB manufacturing technique that impressed me. It was based on covering the copper board with photopolymer daylight resin as the etch resist but the 'clever' part was using an LCD panel as the transparency. The LCD panel was stripped down to its...

    4G/5G etc

    Not familiar with this technology so: Are all the cell masts (stations/transmitters etc) connected to a hi-speed internet connection to give them the capacity to distribute data? If not, how do they each manage to deliver such HSD as 'individual' cells?

    Nostalgia

    Just watched the latest EEVBlog on Youtube where Dave enthuses over the pre-Arduino Single Board Computer that is the PC/104. I could relate to everything he said - pre-empting all his knowledge - just from the fact that I dug one out of my own scrap box a few months ago and spent a...

    Creationism/Intelligent Design

    I wanted to start this thread in the Twighlight Zone for the obvious reasons - and suggest it's put there anyway - but just for the sake of time-wasting discussion...... Leaving the religious aspect out of it - being of sound mind and questioning body I refuse to be drawn into theological...

    Any SDR users?

    My most recent ham radio purchase was a Nooelec SDR receiver and I've spent more time arranging a decent antenna for it than actually exploring its functionality. One area that leaves me perplexed is the software choice to run the SDR with. As much as I've read reviews I've not heard from...

    System resource usage....

    I'm running WIndows 7 on an old Dell laptop (Inspiron 1525) and it generally runs well enough but... ...looking at the system resources in Task Manager I see Firefox is running two instances (even with just one page open), one instance using some 400Mb or resource and the other using some...

    Test Equipment

    What have you got? What would you like? Buy or build? We could (should?) have a discussion on test equipment - is there a sticky post on it? - but this thread is just an opening shot to see how people feel about the stuff. I'm in the market for a new DSO (budget range, I'm not into hi-end...

    Got anything new?

    There's probably already something in existence for anything you try to image but the fun in building something that is unique still tasks me. I have a little 'book' of ideas that require motivation to bring to a finished product but also some ideas that I'd considered that may already in...

    Bit of quiz fun

    I used to enjoy doing the occasional Sudoku puzzle and was amused when a hexadecimal version of it started doing the rounds. Just for fun I reproduce here a typical puzzle that I invite other forum members to have a go at. The usual Sudoku rules apply however this one requires 0-9 and A-F in...
