I wonder. His company has grown significantly since I suggested that he set up a web store last year. It's possible that he has some employees and one of them is a little overzealous. Or maybe he wanted to create an identity that is only used to promote new Arduino products, so that anyone not interested in buying stuff can simply ignore the topic.

Happy Hacking keyboard? They're expensive.

That's a little dinged up compared to how mine arrived...I even had the original manual and spare graticule. But the price + storage function is pretty nice.

I've played with the PoScope a little. It seems pretty useful, especially for microcontroller work.

Once you need to look at signals more than a couple megahertz, it's really inexpensive to pick up a Tek 465B and probes. I got one about 8 years ago for hobby work and it's never let me down. Ok, so storage would be nice, and I use that function of a digital scope at work all the time. It's just the cost issue: 100Mhz analog scope, good condition, $100 range. Good digital scope: order of magnitude more.

Looks like 3 to 6 posts per day, 2 or 3 posts during work hours, and usually small posts. The big posts with quotes, you are doing later in the evening.

No one can focus continuously on a single task, if you take a break every couple hours and spend a few minutes catching up on something you like which could feed back into your job, I don't see a huge problem.

I'm reminded of the Google (and other companies) 20 percent working time for personal projects rule.

This isn't about carry-on, this is about ordering high power laser pointers online. Can't do it anymore, not to the States.

If you haven't left yet, look for high-power green lasers. smiley

You can't order anything over 5mW anymore. I remember playing with a 150mW green laser last year and they're amazing.

Since it seems to be an FDA "recommendation" that is stopping the flow of green lasers, I don't know if it's actually illegal to bring one back with you in your luggage. Might want to check first.

I've also seen DIPs where the skinny part of the leads were just sheared off, and the fat part soldered to the PCB. It looks like a normal through-hole installation except there's no holes. The hard part would be shearing them all at the same length, any difference will make soldering difficult.

You can lay a small metal rod, like a small screwdriver shaft, along the inside of the pin row and then bend everything over by hand or using a flat point screwdriver. However, I almost never do this because I either buy surface mount chips, or resign myself to drilling holes.

Here's one I did just now, using a small drill bit and a screwdriver:

Lose access? Like what...falling victim to a phishing attempt? I've used PayPal for 9 years and put thousands of dollars through it with no problems. Use a strong password, don't access PayPal on computers that aren't yours or may have trojans or viruses, and don't click on sketchy links.

Also, the ability to link to a bank account has been part of PayPal for as long as I can remember....

I don't care how much you like my brain, I'm planning to keep mine. Although if there's a zombie apocalypse, I'll wait to see who the winning side will be and re-evaluate.

Hobby users may like PIC and AVR microcontrollers, but we are by no means the major consideration for both companies. For example, the company I work for has put millions of ATmega chips into products. Other companies use PICs. And competition cannot die because there's also the TI lineup of microcontrollers, Hitachi SH, various 8051 clones by many manufacturers, Freescale's huge lineup of microcontrollers, Cypress, Holtek, Renesas, ST, and so on. Many of these microcontrollers are more widespread than even the PIC series.

I was into the Freescale HC08 series before I was into AVRs, so I'd have no problem switching if it became necessary. I've also been happy with the TI MSP430 chips.

There shouldn't be a significant monopoly effect, I'd only worry about hardware changes or a move to a less open development cycle.

It's unlikely this would have any effect on either of the product lines, but imagine an AVR with DSP like the DSPIC...I know Atmel has the ARM + DSP but it's not quite as accessible.

Just thought I'd comment on this new supplier. Some of us remember the thread here when Eric offered to check around the local Shenzen markets and manufacturers and get us good deals on electronic supplies. Eventually he decided to set up an online store and has been busy filling it with various gadgets.

I just got my first shipment from his store, Seeedstudio. I bought about $300 worth of stuff. He provided me tracking numbers the next day, and the EMS package arrived in about a week, it had to clear US Customs of course. Everything was packed very well and arrived in perfect condition. The products themselves are high quality, especially considering price.

Thanks Eric!

I'm using Flat White Mist fluorescent lighting diffuser panels from Home Depot, vacuum formed into a ring. With water-clear RGB LEDs some additional diffusing is still needed at a distance of 1", so I'll need to add it to the device below.

LED colors never look right on camera...
