Hackaday Links: May 26, 2024

Another day, another crop of newly minted minimal astronauts, as Blue Origin’s New Shepard made a successful suborbital flight this week. Everything seemed to go according to plan, at least until right at the end, when an “unexpected foliage contingency” made astronaut egress a little more complicated than usual. The New Shepard capsule had the bad taste to touch down with a bit of West Texas shrubbery directly aligned with the hatch, making it difficult to find good footing for the platform used by the astronauts for the obligatory “smile and wave” upon exiting. The Blue Origin ground crew, clad in their stylish black and blue outfits that must be murderously impractical in the West Texas desert, stamped down the brush to place the stairway, but had a lot of trouble getting it to sit straight. Even with the impromptu landscaping, the terrain made it tough to get good footing without adding random bits of stuff to prop up one leg, an important task considering that one of the new astronauts was a 90-year-old man. It seems pretty short-sighted not to have adjustable legs on the stairway, but there it is.

The Hacky Throttle Repair That Got Me On The Road Again

Old cars are great. For the nostalgia-obsessed like myself, getting into an old car is like sitting in a living, breathing representation of another time. They also happen to come with their fair share of problems. As the owner of two cars which are nearing their 30th birthdays, you start to face issues that you’d never encounter on a younger automobile. The worst offender of all is plastics. Whether in the interior or in the engine bay, after many years of exposure to the elements, parts become brittle and will crack, snap and shatter at the slightest provocation.

You also get stuck bolts. This was the initial cause of frustration with my Volvo 740 Turbo on a cold Sunday afternoon in May. As I tried in vain to free the fuel rail from its fittings, I tossed a spanner in frustration and I gave up any hope of completing, or indeed, starting the job that day. As I went to move the car back into the driveway, I quickly noticed a new problem. The accelerator was doing approximately nothing. Popping the hood, found the problem and shook my head in resignation. A Volvo 740 Turbo is fitted with a ball-jointed linkage which connects the accelerator cable to the throttle body itself. In my angst, the flying spanner had hit the throttle body and snapped the linkage’s plastic clips. It was at this point that I stormed off, cursing the car that has given me so much trouble over the past year.

Fixing My 4×4: The Battle Of The Bent Valves

If you know me at all, you know I’m a car guy. I’m pretty green as far as hardcore wrenching skills go, but I like to tackle problems with my vehicles myself – I like to learn by doing. What follows is the story of how I learned a few hard lessons when my faithful ride died slowly and painfully in my arms over the final months of 2016.

For context, my beast of a machine was a 1992 Daihatsu Feroza. It’s a 4WD with a 1.6 litre fuel injected four-cylinder engine. It had served me faithfully for over a year and was reading around 295,000 kilometers on the odometer. But I was moving house and needed to pull a trailer with all my possessions on an 800 km journey. I didn’t want to put the stress on the car but I didn’t have a whole lot of choice if I wanted to keep my bed and my prized Ricoh photocopier. I did my best to prepare the car, topping up the oil which had gotten perilously low and fitting new tyres. I’d had a hell of a time over the winter aquaplaning all over the place and wasn’t in the mood for a big ugly crash on the highway. Continue reading “Fixing My 4×4: The Battle Of The Bent Valves”
