Another way to break out dual pin headers

[Uwe] wrote in to share his technique for breaking out dual pin headers. He uses two single pin headers, a piece of protoboard, and a dual row pin socket to make an adapter. This is removable where the other method we saw this week was not.

Web-based slide show hack

Wanting to use an old Android tablet as a digital picture frame, [Gordon] coded up a simple way to use an HTML page to scan your picture directories to feed a rotating background image.

The simplest hot plate

For his chemistry experiments [Charlie] is using a plain old clothes iron for a hot plate. he simply clamps it upside down to the bench. It doesn’t have any stirring abilities, but we already have an old iron in the shop which we use for toner transfer so we’ll have to keep this in mind if we ever need to heat chemicals (might be a good way to warm etchant).

A charging VU meter

This Cambrionix series8 universal charger has columns of LEDs that are animated when a device is charging. [Steve Tyson] works for the company and has had some fun messing with the firmware. He’s showing off the display as a VU meter.

Game Boy knockoff teardown

This wide-form-factor Game Boy is a knockoff from way back when the original system hit the market. You won’t want to miss this lengthy post that takes a look at what’s inside. [Thanks Neil]

  1. That charger is misleading, it doesn’t show the charging progress at all, it just shows the same led scanner effect whenever anything is connected, and I imagine drawing current, and when that current useage drops and will just chage to something else, it doesn’t display the charging progress like it seems it would. They also added a visualiser effect if music is playing. After what I expected, something that got the battery percentage from the actual device, meh.

    1. My nitpick is this: VU means Volume Units, an audio term. Using VU to describe battery charging ( or anything else) just because it is a linear (audio taper?) display is just plain wrong! The term VU predates linear displays, previously displayed with analog meter movements.

    2. At best you could measure the current and run the effect at different speeds. A simpler version could just have a red/green LED that goes green when the device stops drawing much current, indicating that it is charged.

  2. Working at a resort, we use to get a lot of business people from Korea staying. They would constantly destroy the irons by cooking bacon on them every morning despite us telling them not to and billing them for new ones.

    1. That is oddly specific. So specific I did some research.

      As expected there is indeed some bacon specific fetish related to Koreans. It is called Samgyeopsal. The food is called that, not the fetish. Also backing up your story was some pictures of cooking surfaces that have holes, flutes or ports and very low or no sidewalls-you know, just like a clothes iron.
