Passive House

A house that uses as less energy as possible, we call a passive house. For some of you who uses gas to warm your house, is important that you consume the less energy as possibleA little bit introducing about myself: Hello, my name is Nhan.

Hack Your Hot Air Station

It used to be hot air soldering gear was exotic, but not anymore. There are plenty of relatively inexpensive choices. Many of these appear to be the same despite having different brand names and model numbers. One that is common and inexpensive is the 858D. These run about $50. [Gabse] has one and decided to upgrade it using some open source controller hardware and software. There wasn’t a complete guide, so he created one himself.

According to the original GitHub page, the controller will work with the Youyue-858D and any clones. However, there are others like the Atten 858D that use a different controller. In addition, there have been several variants. [Gabse’s] guide is for the latest version. Information on other versions and brands might be on this discussion board thread.

The new controller and firmware offer better temperature regulation, a safety feature that prevents the handpiece from heating up if power is applied when the handpiece is not docked, fan fault detection, a cold air mode, a sleep mode, and more. There are PCBs available from OSH Park if you want to attempt it yourself. There are also a few YouTube videos showing the custom firmware, one of which appears below.

In addition to the controller change, [Gabse] shows you some optional tweaks to make the handpiece more robust, change the power plug, and make the cradle sensor more reliable. Worthwhile changes and all well-suited for the processing power of the Arduino.

We have gotten used to having the handpiece fixed on the bench, that’s another easy hack. You can also try an unholy union of soldering iron and articulated lamp.

Ever hear of the Ford Cylon?

OK, we haven’t heard of a Ford Cylon either. However, there is now a Mustang Cobra out there that has been given a famous Cylon characteristic. [Monta Elkins] picked himself up an aftermarket third brake light assembly, hacked it, and installed it on said Mustang.

The brake light assembly contains 12 LEDs, which unfortunately, are not individually addressable. Additionally, by the looks of it, the brake light housing was not meant to be opened up. That didn’t get [Monta] down though. There’s more than one way to skin a cat, but he chose to use a hot knife to open the assembly, which worked quite well. A rotary cutter tool was used to cut the traces between the LEDs allowing them to be individually controlled with an Arduino. A Bluetooth module allows him to control the new brake light from his smartphone. There are different modes (including a special mode that he shows off at the end of the video) that can be selected via a Bluetooth Terminal app.

There is no schematic or code link in the video itself or the description, but [Monta] did hit the high points. Therefore, it shouldn’t be too hard to replicate.

This isn’t the first brake light hack we’ve featured. This one goes way beyond just animated lightsThis one requires no programming. Rather wear your brake light? We’ve got your back(pack).

Log your hamster’s runs with Arduino

We’ve all seen hamsters in a cage, furiously running nowhere. Perhaps you’ve thought about the pointlessness of this activity, before going to the gym to lift weights up and down or run on a treadmill. From an outside perspective, both activities seem pointless, but when you realize the benefits, maybe tracking what “feats of strength” you’re able to accomplish, things become much more clear.

As seen on Hackaday, in order to track the activity of his daughter’s hamster, John Mueller implemented an Arduino Uno-based system that records revolutions using a magnet and a reed switch. Every time the magnet on the wheel passes the fixed switch, it triggers an Arduino input, recording how many revolutions, and thus how many miles the little guy runs each night. Results are quite impressive considering its size, recording over 3.5 miles on one occasion!

This type of encoder concept could be used in many different situations, such as logging bicycle speeds, or tracking motor stats.

Build your own Arduino balancing robot

If you’re familiar with the Segway or other vehicles that balance in what is known as an “inverted pendulum” configuration, you may think that while interesting, creating something similar would be too complicated or out of your budget. Though perhaps still not simple, Joop Brokking takes you through his design for this type of bot in the video seen here, making it accessible if you’d like to build your own.

The robot, which will cost about $80 in parts, uses two stepper motors for greater movement precision than could be had with normal DC models, and employs an Arduino Pro Mini, along with an MPU-6050 accelerometer/gyroscope for control. It can be driven around by a Wii U-style nunchuck, which transmits to the robot via an Arduino Uno and wireless transceiver module.

You can find more info and product links for this project on Brokking.net.
