That is nice prank. This happens few times a year and it makes all hard, ritual work very interesting. I wish your friend was nice and took this little lightly.

Once when I was at tech college, we were looking at a 1kW transmitter. My friend and I hid behind it (it was a full rack unit with some nice big bottles in it). He lit a cigarette and blew some smoke through from the back. I waited a bit - till the smoke would have been wafting out the front - and then banged the side of the cabinet. Our instructor shut down the transmitter's main power supply pronto. He had a bit of a sense of humour failure and I don't think ever really forgave us, though he did see the funny side of it a bit later. I realised that that it is best to pull these stunts on your colleagues or equals, not your boss or instructor.....

Once when I was an electronics tech fixing pro-audio gear, I was deep into troubleshooting a power supply on a tape deck, when my boss, ever the prankster, rolled his chair over a sheet of bubble wrap. Thought I fried the whole supply and it took quite a while for my heart rate to return to normal.

This reminds me off our boss and sales and marketing department. We did many projects for US DoD and after sending First Article (FA), we at Engineering and Design department eagerly await customer feedback. Many a time my boss and sales people play possum and give us wrong feedback that there is problem in FA and is coming back or order may get cancelled. The concern engineer is so worried for few days or hours and eventually they tell the truth. By this time, they take out some improtant information from us or has got some realy low price for engineering job.

I was working on a bench that looked through the risers on my bench and the one facing my bench towards a third bench where the other hardware design engineer was bringing up an offline smps. There had been had a few small explosions of the power switch as the unite was being tested under high line conditions. I had received a new part packed in large bubble wrap. Not intending to cause a ruckus but just because it is fun to role the stuff up and twist it to pop several bubbles at once, I did. I did not know the guy working on the supply was just turning it on as I gave the first big twist with several loud pops. That guy must have jumped nearly a meter in the air and slammed the switch off. Seeing him jump like that I walked around the bench to see him shaking like a leaf. I apologized and he told me that he was just turning the thing on at high line when the bubbles popped. He went out and smoked a few cigarettes before returning to work. On the next power cycle his supply did emit it's own rather loud report again. I eventually took over that project and that supply is now employed world wide. Even in Russia where the power can swing between 190 and 300VAC!

Back in the 70's I curiously watched as a technician merrily was twisting together a bunch of 4.7 ohm 1 watt resistors together while across the lab another design group was about to power up a several hundred watt switching power supply for the first time. The dynamics of switching power supply design back in the 70's meant there was quite a bit of trepidation during First Turn-On. Meanwhile, our tech had hooked this string of resistors up to a variable transformer connected to the AC line and place them in front of a computer fan. As they started up the power supply, He turned up the voltage just enough to make the resistors began to sweat. After about a minute a very faint wiff of "O' de Ohm" made it across the room, and suddenly we hear "SHUT IT DOWN! SHUT IT DOWN !". I made it a point to not stand to close to the chuckling tech as these miffed engineers turned around and glared.

that's a nasty one. I am very relieved to read that you did not get fired.

Thinking back, I wonder sometimes if I was just an irresponsible idiot at times. Maybe i was, but it now seems that my distorted sense of humor is shared by a large number of excellent engineers. I'm relieved to discover that. Thank you all.

Joshua...there's a saying that's very relevant here. "It's never too late to have a happy childhood" Which is I think what most of us were doing when we got up to these pranks. In most cases they did no long term harm to anyone or anything. As you've observed, Engineers by and large have a good sense of humour (sorry, humor to you!)and often the jokes are appreciated as much by the "jokees" as the joker. I don't think it's irresponsible, jsut makes work more fun.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
