Question about Bayer Garden

Open Question

Your friend Norbert runs a nursery in a small town. Recently a new industry moved into town and drilled several high-volume wells. This caused Norbert?s well to become inadequate for watering his plants. The well will now deliver only one gallon per minute, but it is capable of maintaining this rate for as long as needed. The well casing holds 60 gallons of water, and his well pump is capable of pumping 5 gallons a minute. Norbert only needs 1000 gallons of water each day, but he needs it all in the late afternoon. He has access to a large cistern. Since all of the well-drillers are extremely busy (Norbert isn?t the only one having this problem), for the time being Norbert is pumping all of the water from his well into the cistern every hour so that he can water his plants every day. Aside from the wear-and-tear on the well pump (from pumping the well dry too often), he is becoming grumpy from lack of sleep. He therefore asks you (the bright young engineer) to help him out. The cistern has three float switches (all active high, in other words, if there is water at the level of the switch the output is a ?1?, otherwise it is a ?0?). One of these switches is close to the bottom, indicating that the cistern is just about empty. Another is at the very top, indicating that it is just about full. The third is (conveniently enough) 50 gallons below the top of the cistern. There is also an identical switch in the bottom of the well to indicate that the well itself is about to go dry. The pump motor has it?s own dedicated power supply, but the controller requires a logic ?1? on a line to start the pump, and a logic ?1? on another line to make it stop. It will not hurt anything to assert either of these lines after the pump controller has started or stopped. Norbert also has some timers left over from his automatic sprinkler system. You decide to be a little conservative, and pump 50 gallons out of the well every hour. You want to design a circuit which has the outputs from the four switches and the output from two timers as inputs. Your circuit will output four signals: the signal to start the motor, the signal to stop the motor, an alarm signal indicating that the cistern is dry, and another alarm signal indicating that it has been an hour since you last pumped and the well is still dry. The timers are configured so that one will output a 1 value ten minutes after the start signal is sent (e.g. after about 50 gallons have been pumped), and the other will output a 1 one hour after the start is sent. You?ll use the first timer output to (help) stop the pump, and the second to start it again. The timers are outside of the scope of this lab, and you expect that Norbert might need to tweak them a little to fine-tune your system. Your logic should be such that the motor is told to start if there is room for 50 more gallons in the cistern, it?s been an hour since you last pumped, and the well is not dry (it should also be smart enough to not start the motor if another part of your circuit is telling the motor to stop, but telling it to start after you just told it to start will not hurt anything). Your circuit should tell the motor to stop once it has been pumping for 10 minutes, if the cistern is about to overflow, or if the well starts to run dry. You should set off the alarm to indicate a dry well if the level in the well is low and it has been an hour since you last pumped. The other alarm should be asserted (active high) if the cistern is below the level of the bottom switch (Norbert will use this to shut down the automatic waterers).

SOURCE: takes a long time to heat water

If you are using a 3/8" copper line for your gas, get it replaced ASAP. It will fail. 1/2" Black Iron is required with natural gas. 50 gallons is a lot of water to heat. Look on the heater label for the recovery rate.

SOURCE: My water pump stops and starts. the contacts on

A lot of these pumps do have automatic thermal switches built into the motor end cap, Double check that its being fed the name plate voltage and that the voltage doesn't drop when the pump is running (which would indicate a loose or bad connection or just undersized wire in the circuit)

The idle on the generator went from low to very high and smog came out my magnetic drill now turns very slow what can I do


It sounds like the governor on the generator is not working or something is holding the throttle wide open. That would cause the generator to produce too much voltage for the drill. The armature in the drill has likely been toasted. That's what caused the smoke. The drill may have a short in the windings and some of the plates may even have been melted off the commutator.
It sounds to me like the drill may need its armature rebuilt or the drill may need a new armature. The outer windings may be affected as well. Just before the drill started smoking, I would guess the drill was running faster than normal.

I have an AMSTRAD ALT 286 laptop which is faulty.


The high streets and backstreets of Britain abound with small shops staffed by computer nerds and geeks who will repair lots of things, often at a reasonable price.

There is at least three such shops in this small market town as well as assorted boffins who will help friends and friends of friends.

I suggest you cultivate a different circle of friends, the sort who can offer help and advice of the money-saving sort in all sorts of directions.

I own a DC988 XRP drill. I recently used it for drilling some holes. While drilling I heard a pop and now the drill only spins at a slow speed. Any advice as to what component needs replacing? Brushe


That drill had several speed options, do you have it on high?

Brushes are usually a power/torque issue and wouldn't effect speed unless they were really bad

Short battery life


Batteries have a limited lifespan, typically 3 or 4 years for lithium, more for NiCad and NiMh , and their capacity between charges decreases over the years.
To extend the lifetime of a battery it should be run completely flat after every few charges rather than topping it up. This is essential with NiCads. New batteries need to be charged several times and run flat under normal use before they gain their full capacity.

On one of our two parent receivers, it's showing 1 red light with 4 green lights above it. No sound at all. The other parent receiver works just fine, perfectly clear. I think my toddler was playing...


I had the same thing happen to one of my parent units over the weekend. The issue is that the parent unit lost the pairing with the nursery unit. Once I re-paired them, it's working great again. This is in the Troubleshooting part of the manual, but I've copied below for your convenience.
If Parent Unit won't lock onto the Nursery Unit, or you purchased a new Nursery Unit, follow the procedure below to pair the Parent Unit and Nursery Unit. If you purchased a new Parent Unit, skip Step 1. The new Parent Unit is ready to pair with your Nursery Unit.
1. Erase the Pairing from the Parent Unit. Turn the Parent Unit off. Hold the Volume Down Button on the Parent Unit while pressing the On/Off Button. Continue to hold the Volume Down Button until you hear a single beep and all of the Sound Lights illuminate briefly. Release the Volume Down Button. Press and hold the Volume Down Button again. Within 2 seconds you will hear a beep. Release the Volume Down Button. All of the SoundLights and the red Loss Connection LED will be lit. The Parent Unit is ready to pair with Nursery Unit. 2. Pair the Parent Unit with Nursery. Place Nursery Unit in the same room, five (5) feet (1.5 meters) away from the Parent Unit. Turn on Nursery Unit using the On/Off Button on the side. The green power light should come on. Within a few seconds, the Parent Unit will find the Nursery Unit. The SoundLights will shut off and the Parent Unit will beep. The Parent Unit is now paired with Nursery Unit. 3. Repeat this procedure if you need to pair another Parent Unit with the Nursery Unit.
Nothing happened when I turned on the Nursery Unit. What do I do? First try turning the Nursery Unit off, and then on again. If the Parent Unit still does not pair with the Nursery Unit, press the Channel Button on the Nursery Unit, then turn the Nursery Unit off, and then on again.
Hope this helps.

Grease-encrusted cast iron trivets


Try soaking in hot soapy water that you've dropped several denture cleaning tablets in. That's helped me get some tough stuff off, or at least loosened up enough that some elbow grease and a scrubbie can finish off the job.

Put them in the oven and run the self clean cycle

Oven cleaner. That stuff is second only to industrial grade hydrogen peroxide

Batender's Friend. That stuff is amazing!

Good Luck

Bose Lifestyle 35 Accoustimass module rattles at high volume


Well to be hones 85 sounds pretty loud to me, generally the bose acoustimass module shouldnt really be distorting or crackling unless under extremely high sound levels.

It could possibley be that the speaker cone in the bass module has a slight perforation so it would distort at high levels. However other problems could be loose connections inside the unt or outside the unit. If your friend doesnt have it above 85 under normal circumstances I wouldnt worry to much about it but if there is a tear in the cone the problem could get worse.
