This is a question Home Science

Have you split the atom in your kitchen? Made your own fireworks? Fired a bacon rocket through your window?
We love home science experiments - tell us about your best, preferably with instructions.

I am into Electronics
Here is some of the stuff I have built:


And here is my geek lab:
An Oscilloscope,
Bench Power Supply,
Multimeter (with PC interface)
PIC Programmer.

I bet your local Maplin staff know you by your 1st name...
:-)

eBay is quite often a good source of cheap as chips chips and if you want to order PICs then try getting them from source in China, I got 16F877s for £1.20 a piece and those are the monster 40 pin jobbies, 3x8-bit I/O ports, it's practically half a BBC micro on one chip...

They do actually!
And yes, I use those same pics, and I got them from ebay as well. At the moment, I am building an LED Cube like this one:

build an rgb one like this:

Top quality circuit layout there.
Not exactly nanotechnology!

(although I like your sillyscope)

And not an Arduino in sight.
Marvellous!

self-made PCBs
+10 geek points :-)

using premade jumper pins to solder into veroboard -2 geek points.

and 50 points from Gryffindor. Because.

Those aren't PCBs
No printing being done. I just get mine from a real fab house, lets you do SMT easily.

Well not ALL of them are PCBs
on the far right the TO92-can (EDIT No, they're TO5s) transistors (I assume that's a standard flip flop) look home-etched. But that's a massive step up from veroboard. Bubble etch me a new one, I'll be back for breakfast.

True
I didn't look hard enough!

paxolin to my eyes. Yellowy.
glass fibre looks more transparent whitey waxy

EDIT plus has layers with no copper layers. And fuck those Through Hole Platers.

Twas all fields round here when I was younger.
I will raise you valve radios and a bad ass HMV solid wood radiogram with Garrard record deck. Circa 1960's vintage.

:)

back when valve amps could be tag-board based and no-one died from 200V HT DC :-)
your mathematics were better than ours (bows)
(, Fri 10 Aug 2012, 0:43, closed)
Tag Boards?
Pfft. Octal sockets, wires and I'll have you know around about 295 - 305 Volts AC thank you very much! (OK, current to the valves is about 80mA, but, you don't really want to be touching that...)

Mmmmm... The smell of wax covered resistors in the morning :)

you should totally hit up Edinburgh Hacklab if you haven't already

Top Geekery
But shit wallpaper

Wallpaper?
I see high frequency sidelobe interference leakage from an over-excitable oscilliscope, but no wallpaper.
(, Fri 10 Aug 2012, 22:37, closed)
I dont have the wallpaper any more
I don't even have that room any more, I moved!
