[Bunnie Huang’s] Hardware Talks Top Your Watch List

When [Bunnie] talks, we listen. He is a fount of product engineering knowledge, having seen many of his own products through from concept to market, and frequently helping others do the same. Of course having the knowledge is one thing, but he is also an accomplished speaker who knows what is important and how to share it in a way which is meaningful to others. The latest example of this is a pair of Engineering Talks he gave at Highway 1.

It’ll take you less than twenty minutes to get through the two videos. The first focuses on documentation for manufacturing. What do you need to include on a bill of materials sent to the factory? [Bunnie] has a set of gotchas which illustrate how vital this is. He also discusses how to handle design changes once the manufacturing wheels are already in motion. The second clip covers how Design for Manufacture relates to the actual cost of a production run. We hope there are more of these clips in the publishing pipeline so we’re keeping our eye on this channel.

The two videos are embedded below and at the time of writing had just a couple dozen views each and only one comment between the two of them. It seems sacrilege to say this, but we agree with that YouTube comment; these videos are gold.

Tired of wiring up the power rails and serial adapter every time you build something on a breadboard? [Jason] has you covered. He put his Breadboard Buddy Pro up on Indiegogo, and it does everything you’d expect it to: power rails, USB to UART bridge, and a 3.3 V regulator. Oh, he’s not using an FTDI chip. Neat.

With Christmas around the corner, a lot of those cheap 3-channel RC helicopters are going to find their way into stockings. They’re cool toys, but if you want to really have fun with them, you’ll need to add a penny.

Here’s a crowdfunding campaign for a very interesting IoT module. It’s a UART to WiFi adapter that has enough free Flash and RAM to run your own code, GPIOs, SPI, and PWM functions. Wait a second. This is just an ESP8266 module. Stay classy, Indiegogo.

Mankind has sent space probes to the surface – and received pictures from – Venus, Mars, the Moon, Titan, asteroids Itokawa and Eros, and comet Comet 67P/Churyumov–Gerasimenko. In a beautiful bit of geological irony, every single one of these celestial bodies looks like a rock quarry in Wales. That quarry is now for sale.

Here’s something exceptionally interesting. It’s a browser plugin that takes a BOM, and puts all the components into a cart. Here’s the cool bit: it does it with multiple retailers. The current retailers supported are Mouser, Digikey, Farnell/Element14, Newark, and RS Components.

Want a death ray? Too bad, because it’s already been sold.

[Nick] wrote in to tell us about his first blog post. He’s showing off a PWM LED driver he build around a 555 timer. This project uses a lot of basics; some 555 experience, PCB etching, and surface mount soldering. We’d like to know more about the blue substrate on his circuit board!

After seeing the BOM spreadsheet with KiCAD integration a couple of weeks back, [Vassilis] sent in a link to his own Excel-based Bill of Materials helper. We’re wondering if anyone has a similar tool that will work with Open Office?

While we’re on the topic of downloadable documents, here’s a reference PDF for all types of DC measurements. The collection is a free offering from Keithley. [Thanks Buddy]

Since you’re brushing up on your knowledge you may also be interested in a free online microcontroller course offered by UT Austin. They’re targeting the Tiva C Launchpad as the dev board for the class.

This website seems to be a little creepy, but the teardrop shaped 3D printed music box which is being shown off is actually rather neat.

Hackaday Alum [Phil Burgess] threw together a point and shoot camera for Adafruit. It’s a Raspberry Pi, camera board, touchscreen display, and USB battery all rubber banded together. The processing power of the RPi is used to add image processing effects which are shown off in the demo video.

We don’t own a DeLorean. If we did, we’d probably follow the lead of Queen’s University Belfast and turn it into and electric vehicle. [Thanks Jake]

The 3D photocopiers are coming. Here’s a hacked together proof-of-concept from [Marcelo Ruiz]. After laser scanning the part is milled from floral foam.
