Looks like you hosed it down with Raid, Allan. That bug's dead, dead, deadski!

ps could someone explain how to post a picture directly, not as an attachment....?
Once you attach it, put the link to the attached picture between [img] tags, like this:

Alternatively, post the picture on another site, and use the [img][/img] tags to show it.
Wubba lubba dub dub!

Off-Topic (sorry), but absolutely a work of shame.


for those that can read drum sheet music, my tempo wanders like a drunkard. I would post the midi file, but it isn't listed as an allowed type.

I was just playing around with some recording software, and i finally got it to record from the MIDI interface. Now all i have to do is actually learn drums.

Thanks for the pic post info - I'll use it.

Actually it works?!  - it's a 1-transistor preamp driven by the ripple of an alternator driving a digital input on a pro mini.  Anything above 100mV p-p in gives a rail-rail output.



The frequency is obtained using pulseIn and used to drive a sin/cos meter with lookup tables and analog.out.


Now installed (well, a tidied up version) on my daughter's boat as a revcounter.

I fear you don't need to descend into Fritzing to apply for the wall of shame.

With trepidation I submit my humble entry

Time to get out the hot glue and hide it from humanity ;)

No technical PMs.
The last thing you did is where you should start looking.

To add to my shame - and try the picture posting trick - I enclose a 140MHz saw-based IF filtering/matching section from a 30GHz tranceiver......

The saw manufacturers ( sawtech, now triQuint) give you matching networks, but they may not be optimal for your layout .  No VNA is going to help - it's way off a power match. So you just have to change components and measure.

After a dozen times or so , it gets a bit messy.......

Didn't work... what did I do wrong?

tried again ...Gotcha! - what a cumbersome procedure....

Someone already did (click !), and also told you why you need to do it this way.

Sorry, didn't see there was a next page.
Have a look at "blink without delay".
Did you connect the grounds ?

Ahh yes....

12V SLA charger for a garden sprayer.

Yes someone did plug a 240Vac IEC into the 12Vdc socket on the sprayer.

Fuse in sprayer went bang.
Replaced fuse, everything works.

The stuff soldered on top of the Mini looks normal. Not even any dry joints.

I know. Other than the grime it's a completely respectable point-to-point construction. It doesn't deserve having its own father ashamed of it.

I've done prettier.  Sometimes

Some years ago I was working on a 1.9GHz mobile phone, and finally figured out a problem ( ie my mistake) .  Bodged up a test solution with a stonehenge type mid-air construction of 0402's. Under the microscope it looked b*y awful. But it worked.

Gave the lab technician another 6 to do - and she did - with the unaided eye! And under the microscope they were works of art. And of course they worked perfectly

Good technicians are wonderful!

Don't know if this qualifies for the wall of shame, but I installed Win 10 on a rebuilt computer and was clearing out some unnecessary files when I came across this:
WPNPRMRY.tmp  size:  -1 byte. 
Does deleting it take up more space on the hard drive than keeping it?
If I copy it enough times will I get an extra terabyte of space on the 500Gb HDD?   :o

Coding Badly


What reported that size?  Explorer?

What reported that size?  Explorer?
Wisecare 365. It's usually pretty accurate and clears a load of crud from the hard drive.
