On older vehicles, if you noticed that the lights had gone out behind one of your gauges, you knew it was time to snake your hand back there and replace the little incandescent bulb that had given up the ghost. But what are you supposed to do if you’re seeing the same problem on a modern vehicle that’s already made the leap to LED dash lighting? That’s what [Tysonpower] recently had to find out when the fuel indicator on his Alfa Romeo Giuletta QV went dark.
In the video after the break, [Tysonpower] details how to remove the instrument cluster from the Giuletta’s dash, which we imagine would be a useful little tutorial for anyone who owns the same vehicle. Once he has it out on the bench, he strips it down to the bare PCB and starts (literally) poking around.
He eventually noticed that if he pushed on the board near the fuel indicator he could get the appropriate 3528 SMD LED to light up, but touching up the solder joints didn’t seem to fix the issue. Assuming the LED must be defective internally, he simply replaced it and all was good again.
Well, not exactly. The light produced by the new part didn’t match the color or brightness of the other dozen or so white LEDs that were installed on the board, so [Tysonpower] decided to just dive in and replace them all. While it obviously took a lot more time and effort, he says the end result is that the instrument cluster looks noticeably brighter and crisper when driving at night. Not bad for an afternoon’s work and a couple bucks worth of LEDs.
Most of the time, when we see somebody messing around behind the dash it’s because they intend on replacing the original instruments with something more capable. But projects like this, which add just a touch of refinement to the existing hardware, prove that stock components aren’t always a disappointment.

For those not familiar with sailing, it might seem like an obsolete way to get around on the water. This isn’t 1492 anymore, and it’s pretty easy to go out and get a boat with a motor to get where you need to go. Sailboats, however, are still one of the most efficient ways to travel. There are essentially no fuel costs, and maintenance on them is often easier than on a boat with an engine. Not to mention the fun involved in flying a hull on a catamaran. Anyway, if you’re [gwilken], you can bring your sailboat even further into modern times by building your own sensor array for it.
The ultimate goal of this project was to get all gauges and sensors reporting data to an iPad, rather than to random gauge clusters around the ship. This includes environmental conditions, speed, and motor status (most larger sailboats have a motor for getting around the marina). A Raspberry Pi ties it all together, including a GPS antenna for monitoring location. [gwilken] also includes a WiFi antenna and a cell antenna for maintaining a network connection for reporting all of this information. With this connectivity, he can also control some functions of the boat as well.
[gwilken] made the decision to ditch the conventional gas motor for a more energy-efficient electric motor. This also has the perk of being essentially maintenance-free, and can even charge his battery in regen mode while his boat is under sail. The sailboat is now fully equipped for the 21st century, in a similar way to another boat’s gauge cluster that was recently featured.
A few years back [Evan] built a kegerator from a mini fridge and was quite happy with his new beer chiller. Like many of us do, he started thinking up ways in which he could improve the project as soon as it was completed. While it took a couple of years, he recently got around to adding the temperature and capacity gauges he always wanted.
He added a temperature probe to the refrigerator, and then constructed a pair of tools that he could use to measure how much beer was left in the keg. The volume monitors include a scale built using a pair of pressure sensors from SparkFun, and a flow sensor installed in the beer line.
[Evan] scored an old Chevy gauge cluster and cleaned it up before installing a pair of analog meters which he used to show the keg’s temperature and “fuel” level. Since he feels no project is complete without some LED love, he added a few of them to the display without hesitation. The LEDs calmly pulsate when the keg sits idle, but spring to life and begin flashing when the flow sensor is activated.
As evidenced by this pair of keg monitoring systems, we think that you can never have enough information when it comes to your beer stash, so we really like how this project came together.
Be sure to check out his kegerator’s gauge cluster in the video below.
