I think there was a similar post to this a while back however my current favourite is the ICL7107CPLZ which is one of those old "solution" IC's like the LM3914 - this one is basically a voltmeter made up of an ADC with a built in 7 segment display driver, and you can get an LCD version too (7106)
I learned more from the EEVBlog than I did in school

The LM324, because it's cheap, readily available from multiple manufacturers, widely used and its output goes down to GND.

The 68000. My first computer was a Mac 512KE. This was the first computer I learned programming on and the only processor that I learned how to write assembly for. In fact, I am working on the schematic for a 68000-based computer as I type this.

6809 microprocessor - brilliant instruction set.

And more recently Altera EP2C5Q208 you can do so much with it.

Ha, having suspected issues with a 7106 at the minute so not my favourite ;)

It's nice. The weather is great most of the time, as long as you get used to it. Huricanes are not big deal if you have a concrete home like most people do in the city. Telecommunications are quite advanced compared to other Latin American countries with similar economies. As for neighboring countries, Haiti is not as bad as it is know for in here (people don't trust them, although they are very hard-working). Many Cubans come here, most of them are professionals in their fields (usually medicine and education).

As for tourism, the industry is very advanced and there's lots of stuff too see everywhere, from beaches to mountains. It's not  utopian either, as most developing countries, we still lack basic healthcare services in many places and there's a huge gap between public and private services, specially in healthcare and education. The traffic is a mess, but its messiness depends on the areas you drive on. Anyway I've seen tourists moving here, many in touristic areas, for some reason. They say we are very welcoming and warm towards other people. My opinion is that it varies from person to person, but surely someone's gonna help you out. I have noticed people from the smaller towns are more willing to help.

And finally, for electronics, there are many businesses tat can receive a package in Miami, Fl and ship it here. Then they call you and you get your Digi-Key order. There's also a big market of electronics parts in a street not far away from my home. There are a lot of stores around, possibly 50 or even more. They are sorta like this, just less organized.


You'll be able to find any part made by more than one manufacturer easily. If they are used on repairable electronics, you've got a higher chance. If they are used on power inverters, you'll find them for sure because power inverters are a big business here because of blackouts!

what issues are you getting, I've never tried the 7106 version but I was thinking of doing so because I found a couple in the old shitbin

I used the OSC out ports as a dirty function generator once when I had nothing else to hand but a vero'd up 7107 voltmeter

From the appearance, I know this sounds strange, my favourite is any ics that have the exposed die with those little window for UV, like those eprom or old school dsp chip.

Don't know why, always love to stare at that little piece of finely crafted sand in there. :D

My Atten power supply uses 4 smd ones and the current display on one channel is a bit dodgy. The voltage displays fine (its on the same lcd) and poking around at the chip can get it working but I'm not sure what steps to take now as I've no smd experience

:lol: This brings out some memories (pun intended). You never knew which of those had code in it, which didn't. I was told that if you look at them with a microscope in UV light, you could see the programming going on. I once put a chip into a programmer wrong way up, and for once, I could see the programming going on (I saw flames in window) and afterwards, I could tell it was truly programmed!

On the subject: Motorola 56xxx series DSP. Nice chip to program, and also the chip I've made the most money with.

In the list I'll choose the NE555, but I have another couple of favorites:
Signetics NE5534 (single) and NE5532 (dual) low noise op-amps (circa 1979, if my memory is good).
They allowed  the design of audio equipment (mixing consoles etc.) with fair performance, without costly and bulky discrete op-amp.

I think my favorite is the PIC10F200. They're cheap, effective, simple and more useful than people might think for an MCU with 256 Bytes of ROM and 16 Bytes of RAM. I've done a few peojects with them in the past (mostly for fun) but I have used them in more serious roles like timers and debouncers etc...

I have afew of the projects on my site @ http://smackaay.com buried in various posts on my site.

The Z80 CPU. Ive been using them for twenty years now! Brilliant instruction set simple to use.
