This glowing LED is proof that the experiments [Nvermeer] is doing with conductive ink are working. We’re filing this one as a chemistry hack because  you need to hit the lab ahead of time in order to get the conductivity necessary for success. He reports that this technique uses a copper powder suspended in an epoxy [...]

Nearly everything at [HAD] is at least based on science in some way or another. If, however, you would like to do some actual scientific experiments with stuff around the house, [Observationsblog] might be for you. The particular posts that [Ken] wrote in to tell us about were all about acids, bases, and natural indicators. [...]

Flux generally makes our lives easier. It’s the best bet when trying to prevent solder bridges with fine-pitch components like you see here. But it is also indispensable when it comes to desoldering components from a board (we’re talking just one component without disturbing all of the others). But have you ever looked at what it costs [...]

[William Finucane] is making his own litmus paper by harnessing the power of cabbage. The process is much easier than the faux gunpowder he made, as it take just the one ingredient and a few kitchen tools. In case you’ve forgotten your High School chemistry, Litmus is a set of dyes that change color when [...]

Modern society owes so much to medical research, though what happens behind the scenes in a laboratory is usually far less than glamorous.

[linux-works] picked up an old power supply from eBay, and as it was built back in the 60’s or 70’s, it was in need of a little TLC. One thing that immediately caught his eye was the condition of the knobs, dials, and banana plug receptacles – they were dull and faded, showing off 40+ [...]

Looks like ice-cube trays are once again proving their versatility as this one is serving as the vessel for a home made lead-acid battery.

[Gil] recently wrote in to tell us about some awesome research going on at UCLA.

[Adric Menning] has an unfortunate allergy. He’s allergic to chocolate. Instead of eating the stuff, he’s using it to build model rocket engines.

[Jordan] likes the flexibility that conductive inks offer when putting together electronic circuits, but says that they are often too expensive to purchase in decent quantities, and that they usually require substrate-damaging temperatures to cure.

When we hear about etching PCBs at home we assume that either Ferric Chloride or Cupric Chloride were used to eat away unmasked copper from the boards. But [Quinn Dunki] just wrote up her PCB etching guide and she doesn’t use either of those. Instead, she combines vinegar, hydrogen peroxide, and salt. It’s easier to find vinegar than muriatic [...]

If you have ever produced your own PCBs at home, you know that it can be somewhat of a time consuming process.

[Ben] outdid himself. He successfully made monoliths of silica aerogel in his garage.
