I've been assembling some electronics this week for a ice chest hack.
The problem I'm trying to solve is holding specific temperatures for
prolonged period. When fermenting foods and beverages the temperatures
are often between 60F-90F. The duration is as little as a few hours to
several weeks. I came up with a control system and where the user can
set a desired temperature and then follow the progress via a LCD or on-
line via pachube for data logging purposes. Holding the actual
temperature will be done with a peltier unit because it can both cool
and heat, but I need to build the H-bridge circuit so I can use one
peltier unit and drive it for both hot and cold. Today you can see the
schematic and breadboard. Feedback is welcome.

Situated east of the Imperial Valley agricultural region, the Imperial Sand Dunes Recreation Area is bordered to the west by the Coachella Canal, a waterway diverting Colorado River water to fertile agricultural lands further north. A major east-west route of the Union Pacific railroad skirts its eastern edge, a time-worn testament to the impediment the dunes once played to travel between San Diego and Phoenix.
The dune system consists of three areas. The northernmost area is known as Mammoth Wash. This open area allows OHV use and offers a more isolated experience.
South of Mammoth Wash is the North Algodones Dunes Wilderness. Established in 1994, this area is closed to all mechanized traffic, so access is by foot or on horseback only. Here you will find endless miles of quiet solitude.
The southernmost boundary of the Wilderness is State Highway 78; just south of this highway the largest and most heavily used dunes are found. With some restrictions, these primary dunes may be traveled south toward the Mexican border.

Sometimes septic systems are not installed at the site of a home. It this case, sewer lines from a number of homes share the same trenches as the wastewater is moved to an adjacent area where the drainfields are installed.
L’Ile d’Olkhone, située à environ 250 km d’Irkoutsk, est la plus grande ile du Lac Baïkal. Longue de 70 km et large de 30. Un bac relie cette grande île à la rive occidentale en traversant ce petit détroit qu’on appelle la « porte d’Olkhon ».
la végétation y est plus steppique qu’ailleurs autour du lac. La moitié sud-est de l’île est couverte de forêt de pins et mélèzes, tandis que la moitié nord-ouest est couverte de steppe. Sur cette rive il y a aussi d’importants systèmes dunaires couverts de pinèdes.

Over het Hollands Diep - bij Moerdijk - loopt de Moerdijkbrug. De geklonken spoorbrug - gebouwd begin jaren '50 - kende de afgelopen jaren diverse spoedoperaties aan het spoor. ProRail besloot om in de zomermaanden van 2017 beide sporen op de Moerdijkbrug compleet te vernieuwen. Om de levensduur van de brug te verlengen en het geluid te dempen zijn de sporen ingegoten in Corklast, een speciale elastische rubber-emulsie. Een omvangrijke en lastige klus want de brug is met 5 brugdelen en een aanbrug ook nog eens 1,1 kilometer lang!.
Het project werd in opdracht van ProRail uitgevoerd door Strukton Rail. Van het zogenaamde ERS systeem (embedded Rail System) wordt het plaatsen van de kabelpijpen langs de spoorstaven en het ingieten door Edilon )( Sedra verzorgd. Deze firma verzorgt ook het waterstralen (met een druk van 2500 bar!) van de goten met behulp van een speciaal voor deze brug ontwikkelde robotwagen met 4 roterende nozzles en een waterafzuiginstallatie.
in de nieuwe situatie worden langere spoorstaven van 157 meter gelegd met minder lasnaden om de stabiliteit, stevigheid en levensduur te verbeteren. Tussen elk brugdeel worden in het spoor compensatie-inrichtingen geplaatst om de uitzetting van de brugdelen op te kunnen vangen.

Wow, I think this marks my greatest length of thread-neglect! Almost 5 months! This isn't the new normal though, I will have some time again to work on the car and clear out my parts shelf which once again is getting a little cluttered with the crap I buy on ebay.
I have not done much to the car since my last update besides drive it until the first snow in December. The alternator remains un-rebuilt. Fortunately (?) I made a discovery that the noise I was hearing under certain conditions was not the alternator at all, so it won't need anything besides diode replacement (coming soon).
Now, I did find where the noise was coming from-one of the A.I.R. check valves had failed and sounded something like an accordion for a few minutes when the car was restarted hot. The A.I.R. system switches between two modes of operation-one in which the pump pushes air into the exhaust manifolds, and another in which air gets shot into the catalytic converter-both of which help to keep emissions down. The mode selected depends on what conditions the ECM sees. The check valves keep the boiling hot dirty exhaust from flowing into the hoses and pump which would ruin them in short order-ironically kind of like a diode! In my case, the check valve for the exhaust manifold had failed or was beginning to and on a hot restart the air from the pump would disturb it to create that annoying noise. So it needed to be replaced. Here is the part in question in case you have never heard of/seen it (I didn't)
It is in the vicinity of the power module
The little bastard screws onto a "T" fitting that looked more like plumbing equipment than an auto part to me. On each side of the T, there is a metal line that runs to each exhaust manifold. Clean air flows through the check valve when the switching valve directs air to it.
While the two lines came off easily, the check valve itself was stuck like you would not believe. The tee fits into a 7/8ths wrench, and the captured nut on the valve is 1 inch, and using my two largest wrenches on each with every ounce of strength I had I was only able to break them loose after soaking in transmission fluid for a few days. And even then just barely.
The exact part number of the failed valve was not available so I substituted another one that was otherwise identical. I suspect the differences in part numbers (there are a ton of them) have to do with unique backpressures for every engine configuration GM made across all their cars. I bought one spec'd for a 307 Olds V8, which I figure is as close to the 4100 in terms of back pressure as I could get. Could be totally wrong on that too. Anyway, it no longer makes the noise!
Now the other part of the A.I.R. system is for the catalytic converter. The check valve on this one was good, and I suspect it lives a much easier life than the one for the manifolds as it is not subjected to the high pressures or heat. But it needed love too, when I had the catalytic converter changed, the shop cut off the end of the pipe which entered the old bead converter at a 90 degree angle and used high temperature hose to make the connection.
I can't say I was happy with the way it looked but it seemed to do the job. Except that when braking or accelerating hard, the hose would allow the metal tubing (now loose) to move back and forth which made for an annoying knock. I wasn't sure what to do but I was certainly surprised when I learned Rockauto still stocks this pre-bent metal tubing unique for the 84-85 Eldorado. Go figure. I ordered it and when it arrived, I was disappointed to discover that it lacked the mounting bracket that goes up near the engine. So I ended up taking my old and new tube to a welder who transferred the bracket to the new one for me.
I also put a new check valve on it. Note that this valve lacks the captured nut. That is a catalytic converter check valve and it is physically smaller than the one for the manifold. They thread size is the same, but the nipple is the part that won't allow you to put the other diameter hose on it.
Here it is mounted to the "new" cat. I have to spin that clamp at the Y fitting, it should face the passenger side. Bah shops! So, that concludes today's edition of what invisible repair I managed to waste my time and money on!

SECRETS, DETAILS AND OPTIONS FOR THE BREMBO BRAKING SYSTEM ON THE MOST POWERFUL STREET ALFA ROMEO EVER
You've been waiting months, looking for information about it and harbouring hope of a sneak peek. Now that the Alfa Romeo Giulia has arrived in the dealerships, you know everything (almost) about it, but perhaps details on the brakes have escaped you. This information is far from insignificant for a car comprising a 510-hp 2.9-litre twin-turbo V6 gas engine and 600 Nm of torque.
Brembo takes care of filling this gap by revealing all the secrets of the two braking systems (one as standard equipment, one as an optional) for those who are getting ready to purchase an Alfa Romeo Giulia Quadrifoglio.
When "standard equipment" goes way beyond
To stop the Giulia Quadrifoglio, Brembo has provided a stock braking system that very few street cars can boast. It is called the High-performance Brembo brake system, and it comprises Brembo co-cast floating ventilated discs measuring 360 mm in the front and 350 mm in the rear. Not everyone is familiar with co-cast discs. This calls for an explanation.
Co-cast discs bring together the benefits of the two materials that they are made with: cast iron (for its thermal properties, like a reduction in deformation and good conductivity) and aluminium (for its lightness). The distinctive traits comprise the way in which the two materials have been cast into a single component and the behaviour of the disc itself. Indeed, it is a fully-integrated disc at low temperatures, yet it acts like a floating disc at high temperatures when maximum performance is required and the disc tends to get deformed.
Combining these discs with anonymous calipers would have been sacrilege. To exalt the sides of this car, which are enriched with prominent beltlines, Brembo monobloc calipers were chosen with 6 pistons in the front and 4 pistons in the rear. This choice reaffirms the strong personality of the Alfa Romeo Quadrifoglio.
Carbon-ceramic for those who want the best
This may have been enough, but the engineers and designers at Alfa Romeo decided to push the limit. To satisfy everyone who truly wants the best in terms of brake performance, an optional braking system is available: the Ultra-high-performance Brembo carbon ceramic material (CCM) brake system.
More specifically, these floating ventilated discs are made of carbon-ceramic and measure 390 mm in the front and 360 mm in the rear. These will tempt the most refined palettes because carbon ceramic is characterised by low deformation at high temperatures, a trait that is directly reflected in the car's performance. This material, which Brembo has used on production cars since 2002 (the first was the Ferrari Enzo), isn't afraid of repetitive use.
Notwithstanding intense actuation, the brake force remains unchanged. Even in the most challenging braking, the carbon-ceramic disc never risks succumbing to fading, the phenomenon that occurs when the brakes lose efficiency after overheating. Braking better and doing so for an almost infinite number of times without losing efficiency are two of the greatest aspirations for drivers who favour Alfa Romeo. But we still need to talk about another benefit of the carbon-ceramic discs: their natural state makes them much lighter than traditional discs, which affects the mass of the entire saloon.
Ultimately, with the Ultra-high-performance Brembo carbon ceramic material (CCM) brake system , improvements are seen in acceleration and driver comfort, and, to cap it all, consumption goes down. The extremely high-performing, light-weight discs are accompanied by monobloc aluminium calipers with 6 pistons in the front and 4 pistons in the rear. The front calipers are characterised by a different structure with respect to the standard equipment, one that was designed to meet the specifications of carbon-ceramic discs.
The world is better in colour
We almost forgot to tell you that both sets of calipers come with the iconic Alfa Romeo signature. In order to match the 7 colours of the chassis, Brembo has created calipers in three different shades: the unmistakable Brembo red with white writing, vivacious yellow with a black logo and aggressive black with red writing. It won't be easy to choose.
Electric handbrake
You won't need to exert any effort in the selection of the electronics. Both Brembo braking systems include an electric handbrake. Rather than the classic handbrake lever, there is a system comprising a driver-switch command (to put it simply, a button), an electric command and electromechanical actuation that is independent from the rest of the braking system. It is easier done than said: to disable it, you just press the designated button on the instrument panel while pushing on the brake pedal.
Amongst the many advantages of an electric handbrake is that of Drive Away where the command is automatically disabled one the car is put into gear, the clutch is released and the accelerator pushed. Thanks to mechatronics, which brings together different disciplines like mechanics, electronics and information technology, Brembo integrated the management and monitoring software of the handbrake's small dedicated caliper within the control unit of the vehicle dynamics (ESC).
Alfa Romeo Giulia Quadrifoglio, unequivocal emotion, even in the braking system.
