News - T³: Etching your own cir…
about 6 months ago
I’ve never tried etching my own PCBs, so I can’t speak from experience, but I’ve heard you can drop off the chemicals at your local fire department. My area will also hold eWaste and other hazardous recycling events where you can drop off old electronics and other materials. They may accept certain solutions, but again, I can’t say for certain. They usually send out a flyer notifying residents of dates and acceptable waste.
A good note to all readers would be to make sure to properly label all containers, your solutions and your wastes. Not only do you want to know what’s in the container, but when you dispose of these containers at (say) the fire department, they may want to know exactly (or need to know for certain) what’s in the container.
Also remember “AAA” or “Always Add Acid .”

Thanks for the heads up. If I recall correctly, previous years you were limited to 2. This may make it a very interesting weekend! :)
Is there anyway to know what the limited quantities will be, and on which items, so I can properly allocate my spending?

News - Enginursday: Supplies!
A couple of years ago, in needing of an automotive car charger, I picked one up at a discount store. Although I don’t have definitive proof, I ended up poor battery performance down the line. It certainly could have been the phone, but I have always wondered. More so that charger eventually stopped working, the wires in the cord were extremely thin and eventually broke near the plug for the phone.
That also reminds me when I used to do automotive electronics installations (radios, subwoofers, etc.). We would often get customers that bought amp wiring kits bought off of eBay or discount stores so they could save costs. I always thought the more expensive kits met the gauge of the wire at a minimum, whereas the cheaper versions seemed to include the outer insulation jacket in their gauge number. Even the insulation jacket seemed a bit thicker.
Question: [As someone who isn’t an engineer, or has stepped foot in an engineering class] Do you think open source allows more coverage of the engineering triangle? I could see that one of the benefits of open source is that something can still be designed quickly, designed well (how often have you taken a product and thought you could design better, with or without some flaw), and improve these without sacrificing costs, or finding alternatives that may reduce costs (I’ll exclude the idea of group purchasing power). I would think the Arduino is a good example (please correct me if I’m mislead), but there are so many clones now. The Sparkfun Redboard for example, not to mention all the counterfeit Arduino (and Sparkfun) boards you can get at a fraction of the cost. That’s at least how I see it, but I would like to hear from those of you closer to the subject.

I might have to put that sticker design on a flyer and leave them around campus.

If only Van Gogh knew you could reattach ears using a soldering iron, but then again modern medicine has advanced such a long way.
