Easy Street took a serious beating about 21 hours ago. It is on life support. I was drinking quite a bit and the tire went completely flat about half way home. I did not see anything that punctured the tire but hit a pot hole earlier on.
I was tired and p i s s e d off because i had to walk and was losing my buzz. I slammed it on the sidewalk about 10 times. Then while walking it the tube started wrapping around the axle. It happened before with the last flat tire and I had a hell of a time. I had to carry it most of the way up the hill before I could change it the first time.
I was in no condition to carry it to storage so I bit the tube in half. I made it to storage and was tired and hungry. I started walking about 1/2 mile more towards Taco bell to get breakfast after taking $20 out of storage and locking up poor easy street. I ended up laying down in the grass a minute then continued walking.
I was about 300 feet from Taco bell when the ambulance rolled up and wanted to take me to the hospital. I told them I was just hungry and felt dizzy for a minute. I said I would be ok once I had breakfast. They said we have food at the hospital. I said Taco Bell is right there and I smell the sausage. I continued to walk and ordered two sausage egg and cheese rolls and a hash-brown and a large cup of water.
A cop walked in when I was almost finished and asked if I was feeling better. I said yes. he said I will order you more food and asked me what I wanted. I said I could eat another sausage roll and another hash-brown. He ordered that and handed me a couple of bucks. He said "don't spend it on beer ". I said Thank you very much. I walked home and the ol lady was still up at 8:30 AM waiting for me. I slept until 6:45 PM. I am a lazy alcoholic.
I bought five 25 oz cans earlier about 10: 30 PM and went to storage to get the SONA packs I was running last night when all that happened. am about to open one now at 4:05 AM. I will do a video with the new dual motor build if it is not raining tomorrow.
The rim on Easy Street does not seem to be bent but one of the plastic Tupperware containers was cracked but when I checked the voltage it was ok. I will check out the bike frame and see if any damage was done when I get around to it. I was a drunken idiot and beat up one of my best bikes.
They are charging now and will separate and check each pack and tape up the cracked plastic and will be hooking them up tomorrow to the rear motor and the three Samsung packs to the front hub motor as I will only use both motors when climbing hills. I may not run Easy Street again until after I move as there are too many pot holes around here. I think 20 inch wheels are better than skinny 700 c wheels on rough roads. Thanks.
First few years, I don't overclock. When it gets a bit older, I start overclocking. My 3770k on single thread performance still outperforms a stock 8700k, although it uses more power and generates more heat to do that. Using this strategy allowed me to skip 5 generations of chips.
Doug and I discussing case modifications. I asked a guy at the computer store about mineral oil cooling. The guy said it made a mother board fall apart after 6 months. I am wondering if there are motherboards that are made of a material which can stand up to mineral oil. If not a cheap board or upgrade every six months or a model the same as a model proven to last at least a year with oil cooling.
There are many disadvantages to oil filled cases which are similar to the paradox of hydro vs soil due to PH lockout and what not. and I invented a way to do both which sported about 8 years of success. My solution to oil cooling is a decent board which can be used for over-clocking and submerge the side of the board closest to the CPU and memory if possible and run a liquid cooling system thru the mineral oil close to the processor and ram.
All hard drives and optical drives will be in the air and USB HDMI ect ports will be out of the oil as well as Freon or nitrogen cooling block / blocks or small radiators and a four 120 mm. fan cooling system 2 fans for intake and two for exhaust.
Also if there were to be a way to put a DC motor into a container filled with mineral oil and hook up a cooler that could work as well and also with the controller. Not sure about batteries and or old school vintage audio equipment.
All or most electronics power handling capacity is directly related to cooling capacity. It would most likely only be practical for small brush-less RC motors as the larger the motor the more weight the oil would create. Not sure what or which material is suitable to be submerged in oil. However with 3D printing and material science technology which I took in college and got a B in back in 2006 I see possibilities in many electronic fields.
Thanks and let me know if any of that is possible.
I separated the SONA packs and tested voltage. 4.02V. The new LG packs are 3.98V. I put them on charge. I know the front 800 watt hub motor will work on the 10S packs. I am thinking 8P would be better for the front motor and I could really benefit if I were to parallel the new LG packs to the SONA packs for the front hub motor and run the three Samsung packs for the rear. Wtuber should be proud also as he stated as well as DA that the more packs in parallel the better.
The LG packs already failed miserably with the plastic caps up a medium size hill in 12S - 2P mode. That is why I am paralleling them to the SONA packs for 8P - 10S now. The front motor run exclusively on flat ground. UP hills the 6P Samsung pack will boost the rear motor and total power will be approx. 1,300 watts with approx. 22 mph gearing both motors working together. Total battery input power will be 14P @ 10S.
Again I can't take total credit for this. Only the imagination or creative part as I am a great innovator. Without you ES members who help me on a regular basis teaching me the basics of motors , controllers and batteries including building them this would be impossible
PS. The 27.5" bike that is in the pictures beside the current 20" build (top bottom last post and lower bottom this post) sports disk front and rear and dual suspension. It is NOT a 20" kids bike and will be my first belt drive hopefully and am looking at a custom built 60 volt pack and 60 volt controller and the 48V 1,800W brushless motor and 40+ mph gearing.
I cannot hook the new LG packs to the SONA packs for 8P as the BMS on the LG packs is different than the BMS on the SONA packs. I was going to wire nut them together. However the BMS on the LG packs have separate run and charge wires. I would need parallel cables and probably will not remember and screw up the LG packs by charging them wrong. I will only be able to run the rear motor off the SONA packs I guess. Please let me know if otherwise.
I remember posting a video running a motor with the BMS using the charge port by accident at 0 load and the cable got hot but the system did not fail and is currently working. I am not sure if the opposite configuration charging thu the run port of the BMS could be possible or not. I am disenchanted that the BMSs are different on the LG packs I built and the SONA packs I bought. Please let me know. Thanks.
4P for the rear motor and 6P for front is final decision. Total P up hills is still 10P. No I wont say the G word but I am a smart guy. It is 9:43 AM and am hungry for sausage again. Stewart's has them and is a only about 3 blocks away.
I am sorry. Mostly apologizing to myself. I have very little self control. I am not just a lazy alcoholic. It is much worse than that or better depending how you look at it. Many alcoholics who don't eat enough destroy their livers < half way thru a normal life span.
I am a FAT lazy alcoholic. My friend downtown wanted to continue drinking after we polished off an 18 pack and a 25 oz bud ice. I did not feel like waiting for the store to start selling beer at 8 AM on Sunday and loaded the new dual motor bike up with empty cans and went to storage. I was hungry and went to McDonald's again and spent $17 on breakfast knowing there was a chicken leg in the fridge saved for me.
Drinking is not my only downfall. I am very addicted to fast food. Two sausage mc-muffins and three hashbrowns and a steak egg and cheese. At least I bought two steak ,egg and cheese and brought one back for my ol lady.
The dual cargo bike is running great and takes hills seemingly effortlessly. The range has greatly improved and running the front motor at 6P - 70% of the time and kicking in the rear motor for hills and slight inclines also seems to work out very well. However on the down side it is now much easier for me to get to fast food restaurants.
I was limited to Stewart's after returning from downtown running a single motor and single pack. Since their breakfast sandwich is not nearly as good I would eat one and a small OJ. Now I have that extra 2 miles. I might never be able to afford to move. My beer bill and food bill is kicking my a s s . Thanks.
I build e bikes. There not always pretty or practical but sometimes they work, at least for awhile. Immortality is not a dream but the future of our evolution. We were given the tools to forge our own destiny. We were created in gods image and shall evolve to live forever.
