content: Hi All,Just received a 'new' 289 and it came in a thin card box with no real packing, no peel off film over the display and the batteries already installed. Is this how Fluke stuff comes nowadays?

content: Should come in a nice printed yellow and black box. Substantial cardboard tray inside with meter, probes, CD, manuals (sealed), warranty card, film on display. Batteries are always installed. Probs got one lying around to take a picture if you want.

content: I've stockpiled some old and useless circuit boards in anticipation of getting my hot air rework station. Now that I have it, I've been practicing removing chips with it (so much fun!).Anyways, one of the boards I have is fairly big, it's out of an old pentium/compaq box. It literally took up almost every square inch of side space in the casing. It's around 350x235mm in area! Just wondering if there is anything cool I could try doing with it once I'm done removing chips from the board.

content: Biggest circuit board I ever saw was roughly 500mm x 800mm, hot swappable "printed wire board", that is, it was a basic double sided FR4 type board (power and ground), then each side had an 'epoxy' type layer covering it, with two layers of thin enameled wire embedded into the 'epoxy'(or whatever the compound was). This was back before micros came into general use, so all TTL, over 400 chips per board. The developers spent untold $millions designing these boards and building test and debugging logic into them so that faults could be diagnosed to chip level and several guys from oz were sent overseas and trained to repair them.What eventually happened was that someone back in the US "repaired a card" so badly that it had to be scrapped. After that ALL cards had to be swapped out and faulty ones returned to the factory, that was the start of us becoming card jockeys.

content: You what? Recently I've become interested in RC planes and now I'm having fun trying to put together a plane made out of foam and thin plywood and that brand new hobby got me thinking about my electronics hobby.As I progressed in my electronics hobby I stopped following other's fun circuits and schematics, like Forrest Mims' circuits on the Electronics Learning Lab, countless little circuits online, datasheet designs and readymade projects online. Instead I started to design stuff. The only two boards I have he'd fabbed in China were simple, relatively basic designs using microcontrollers. Not beginner circuits but they easy to design nonetheless.Then designs got harder and having challenging designs meant spending either lots of time or money, or both. I started to go to my lab less frequently and now I barely go weekly.Then I found the instantfunin printing out plans for a small RC plane, looking for the right materials, making it dirt cheap... and I realized electronics as a hobby shouldn't be about having ahardtime designing challenging and impressive designs, it's about having fun! Making fun designs, maybe quick and messy, maybe the opposite.We shouldn't be trying to impress everyone with our electronics expertise -that's what jobs and research are for, so go and become the next Jim Williams if you like. Me? I'm going to have fun with my hobby again.

content: I was trying to make truly advanced electronics but that not often done for hobby I think. The experience needed, for example, to make the EEVBlog (impressive work that sometimes goes into advanced topics) isn't obtained all from your hobby. Dave had many jobs and most of his videos, I would say, go back to something he probably learned at work. For example all the Digital Signal Analyzer stuff was from the seismic industry he said he worked at. Remember the Altium tutorials, PCB for manufacture tutorials. Many of Mike's videos are related to his work too.

content: I can't help feeling that Motorola is just cashing in on good will with this.The drivers for mobile phones are features, size, battery life, weight, performance.Modular phones would significantly impact all of those. If I have to design a Wifi module, it will necessarily be larger to accomodate a specific mounting and interconnect system, and therefore more expensive, and will perform in a lesser manner because of that too. Same with all the other parts.Not to mention - how do you add new tech when things are so integrated nowadays? It's not like you could really just add a "front facing camera block" to such a phone - because you can't conceive what and where the new tech will be or go.So you wind up with a shitty phone that has bad battery life, is bigger, heavier and more expensive than the competition. Then Apple comes out with the iPhone 7 with a bigger screen, thinner, lighter, more memory, faster, 8G at 100mbps speed, Wifi eleventy and retina recognition, for less than the modular phone. No-brainer.

content: Just because theycanmeasure in circuit, doesn't mean youshouldmeasure them in circuit. There's a distinction between "can measure but who cares if the results are accurate" and "can measure and give good results".Capacitors in parallel will distort the reading. Even a simple ceramic capacitor in parallel with the electrolytic you try to measure can affect a reading.If you want a proper LCR meter, Uni-T UT612 is a good choice. Same with Mastech MS5308, which Martin (mjlorton) and jwrelectro reviewed thoroughly:I'm not sure but I think both UT612 and the Mastech use the same pair of chips internally. Check the videos and the ut612 teardown here on this forum.Be careful though because these LCR meters don't handle charged capacitors well, I think the ut612 says it can handle only up to 30v and that capacitors should be discharged first. But I'm not sure, and I'm not sure about the Mastech.The peak esr70 is imho not worth the money, it's too expensive for what it does (approximates the esr just like Blue ESR ( linkshereorhere) or esr-Micro which has a page here :google translationI have ESR Micro and it's a great tool for the money I paid for it (about 60$, nowadays it probably costs about 75$. If you're interested, you're probably better off contacting directly the designer on badcaps.net forum, his username is RusMike. That's how I got mine.

Even trying to make a reasonable facsimile that most people would recognize is going to cost you about $100 total.So now I know the recipe for Adafruit's I2C LED modules, I assume I could get some cheap chinese imports and slap some chips on the back.

The production chips were fabbed on either Sharp or Macronix lines.They were very orthogonal RISC machines. Instead of a jump, you load the PC.Its not entirely impossible that some of the Argonaut folks knew friends at Acorn computer and borrowed a few ideas from ARM.I was the first guy to try putting a faster crystal on the pcb to overclock them , haha. They were very conservatively clocked.The DSP1 is a NEC cpu running a small binary from internal ROM. It has commands for calculating arctangents, doing perspective transformations, and so on. It's been decapped and dumped. I believe bsnes actually has the nec core in it running the dumped ROM for accuracy's sake.

To me it would have seemed to be cheaper to just make a really cheap stacked insert that contained the new chip and sell them for next to nothing rather than put one in each cart. Just standardize on one chip and go from there.I know Sega had the 32X but it was expensive. If the SuperFX and/or DSP1 chips were cheap enough to put in cartridges, a passthrough option should have been cheap as well.
