Back in the 70's and 80's there were lots of places selling semiconductor bars (primarily for teaching purposes). Today I've been looking for a source but am not having much success, does anyone know where I can buy some (n and p doped bars, longer than say 3mm).

In junior high, before my family had a "real" computer, I cranked out many a school report on my parent's Panasonic Penwriter word processor. It was like an electronic typewriter with a tiny LCD display for entering text, but instead of a daisy wheel or something it had four color pens controlled by servos and some limited ability to do vector graphics, I remember doing some really nice-...

Hello, I just experienced a very weird internet outage/partial fall out. It was very weird and only last for a minute or so, some websites failed to load, others half, some fully but slowly. It might have been some kind of radio or satelite link being affected. But I don't think my traffic goes via that because then the latency should be above 500 milliseconds or something and it

Hi, I have an ADC application where I am reading the output of a voltage transducer. The transducer has a 1.36 to 0.7 V range, the conversion rate is in the range of 1 uS and probably around 10 bits of resolution will suffice. My main concern is that that the transducer output is 6 feet from the proposed circuit board location. I will low pass the the input to the A/D with a filter

LPC804: 15 MHz Cortex M0+, 32kB flash, 4k RAM, 12-bit 2 us ADC with 1 LSB DNL, 10-bit DAC, the usual serial stuff, 20-TSSOP: 67 cents in reels, dev board $27. We're using it for a super-quiet diode laser controller where it will run the temperature control and automatic power control loops. I'll never use another ATmega. ;) Cheers Phil Hobbs -- Dr Philip C D Hobbs Principa...

The Swedish Democrats are projected to get 20% of the vote today, but polls world-wide consistently underestimate the numbers of right-of- centre voters who often feel embarrassed by the pollsters and claim to be left-of-centre voters with 'Liberal' voting intentions.

I have lots of old program sources and listings that have embedded formfeed characters to page the listings. But modern printers seem to ignore them, maybe print a little box but not eject the rest of the page. Does anyone know of a way to print properly paged listings on a networked digital copier or laser printer? Crimson Editor can't do this. -- John Larkin Highland T...
