  1. One Week in Shop, And New Blog

    After 1 week of being in shop let me show you guys how much i got done to get it online First i sourced a 6 foot 3 shelve industrial shelve a 8 foot x 30 inch table took everything from my parents place and stored it in the cage put ssd in old laptop and now it will be permanently used in the cage. also bought a lot of tools that will be used at tech shop rather than relying on tech shop to have the tools when i need them check out the pictures bellow generally each picture represents a day of setting up the cage over a week period. so you will be able to see the progress. also i will be starting a general blog called The Green Engineers Official Blog that will cover general stuff like this. check it out for periodic company updates.
  2. Major Update: 7/28/17

    Today i secured The Green Engineers first work space It is the basement(lower floor) of tech shop san jose it is a 8'x12' "maker cage" So finally i can ge the stuff out of my parents place("storage") and into the place that i work on it No more lost tools and parts because someone moved them finally going to have one place to store everything this will speed up all work So now i will begin bringing everything that is involved with The Green Engineers into the "shop" and for the next little while every time that i go to tech shop i will be dropping stuff off and "furnishing it" super excited as this is a big move for The Green Engineers This should bring great efficiency to working on projects in a more timely manner check bellow for images of the currently as of today empty maker cage. Now The Green Engineers HQ. another big update on multistruder coming soon.

  4. 7/27/2017: Update

    Did some more cuts on the plasma i am struggling to get good cuts on it so i think im going to transition to using the water jet till i get the cutting right on the plasma so my expenses per shredder have just gone up drastically. each shredder should cost around 100$ to cut so once i get a prototype built the price for further units is going to jump drastically. im thinking somewhere along the $200 mark initially however it is going to decrease my time in post processing the steel to clean it up also this week i tried to heat treat the steel in a electric kiln at tech shop redwood city i found some issues with heat monitoring and decarbonization because of an oxygen deprived environment inside the kiln. but i bought some hardness testing files to test the rockwell C of the steel post heat treating and they are on there way from japan. also i will probably start designing my own kill to introduce carbon into the compartment to carbonize and prevent decarbonize. check bellow for some awesome images. stay tuned for big update by end of week.

    went to cut some more wens day and the cam software running the cutter is ignoring the inner squares on the spacers so need to figure out why it is doing that. but going to be cutting again this weekend.
  6. 7/17/2017: Update

    Got some cutting in this week Got the calibration of the fusion 360 done to get the center square perfect going to finish up an entire shredder this coming weekend i am still shopping for bearing setup and a drive shaft supplier full product coming very soon Check bellow for a lot of pictures.
  7. Update: 7/9/2017

    I have purchased and received the plate of steel. It is beautiful. 1055 1/4 inch steel 4' x 8' However now i need to figure out how to get it out of the back of my truck and into tech shop redwood city. as tech shop redwood city has no grade level door and no forklift from what i believe so it probably needs to be rolled in through front door on dolly. i was trying to go today but for whatever reason they were closed or something i am going to try to go tomorrow Sunday but i have a lot of summer class homework so i will see what is going on. As i am definitely going to talk to them to see what we can do. i also got a 3/4" solid square bar to check my holes to make sure they are correct. i will do the best i can to start cutting asap. Pictures of plate down bellow
  8. Hey guys if you would like me to send your basic unit to you while i finish work on the modules let me know and i can send them out to you asap. then i can send the modules out to you when they are finished. First come first serve. Otherwise hang tight and i will get them both to you at the same time.
  9. Update: 6/29/2017

    Hey guys sorry again for the radio silence. The reason why i have been gone is i have picked up a summer job to get some more funds for my project So here is a deal i am thinking about the fastest way of getting these out to you. This weekend i will be coming up with a solution. What i was thinking was to ship out the base model to you guys. Then shipping out the modules and me just bite the financial bullet of shipping 2 boxes. Also i dont think the entire thing will fit in that box safely. It would probably fit just not safely.

    yes posting update right now.
  11. Update: 6/21/2017

    I have finally tried the cut on the shopbot with a 3/32 square endmill 3/8 LOC and 1 1/2 overall long story short i picked wrong parameters and broke the endmill in about 5 seconds. within a cut of half a inch. so we have a few options either i can keep trying to figure out the parameters while paying for 15 dollar endmills every mistake. and supposibly even if you get the parameters right these endmills only last for less than 1 shredder each. or i up the endmill size but that would cause larger radius which would mean loss of detail and material. all of these cause alot of problems So i think i have come to the decision to make the cnc plasma my production machine. Then i will just spend the time to get rid of the taper problems. Most of the taper problems are just the inner square for shaft. so maybe a broach or a router bit i sent another inquiry to the steel company for the sheet. setup delivery locally for pickup. However the sheet for delivery is quite a bit more than i originally thought. I will be doing some summer work helping out starting monday so i will be able to get the sheet soon.
  12. Update: 6/10/2017

    Back home from vacation Going to try something new for first shredder. Tech shop is going to allow me to use the 4'x8' shopbot to try to cut with i have a 3/32" 2 flute end mill We are going to see what kind of quality i can get out of the shop bot as calculators say i can do 35.4 ipm so it wont be too bad on time even though first time im going to do a conservative depth of cut per pass i think the quality is going to be quite a bit better than the plasma and also the radius of the corners will also not be that bad as it would be 3/64th radius. endmill coming tomorrow going to be getting steel during week try first shredder this weekend. generating g-code now for shopbot.
  13. 76th Week: 5/30/2017

    Sorry for the radio silence I am out of school and currently on vacation in hawaii till the 10th of this next month because i am out of school i am back on full time on the project i will be assembling the units first thing when i get out
  14. 5/24/2017 Update

    Finished school monday. Back on full time Went to redwood city techshop again and cut the gears. The gears were the first cuts using fusion 360 cam aka hsm works they had a weird twist in the gear i found out that that was because the arc in the plasma actually bends twords where the ground is and the twist was twords the ground clamp. the cam gcode was not plug and play. i had to modify it to work on torchmate. So i am going to go into more detail on what torchmate didn't like and make sure that that gcode is not outputted. However. fusion 360 still does not have nesting capabilities So i will try to use vcarve pro to do the gcode as it has nesting capabilities. I also had the chance to do varying speed lines on the plasma I did this to check to see ideal speeds to minimize dross which minimizes post cleanup. i started with 19 lines each with dropping speeds of 5 ipm with each line i found that 7 (70 - 40 ipm) of those lines had the least dross. i then put those into a array of 7 lines spread apart and cut them again to better see the dross more clearly and picked the best one i believe 65 ipm i plan on going back to tech shop redwood city tomorrow to cut out a full shredder to gauge the post cleanup. And also time the post cleanup i will be trying to use vcarve pro to do the nesting for the 4x12 plates of a36 to do an entire shredder. I will then try to assemble and see how it goes. However, i will be going on vacation with my family on Friday for 2 weeks. so i will only be working on the gcode from there. so if the a36 goes well i will pick up the 1045 plate from supplier and start cutting. I will also try to get the hardening option up on my store if anyone is interested in that. check below for more pictures.
  15. 73rd Week: 5/9/2017

    Have been swamped with school projects, tests, hw, and finals. so i will not have prototype by maker fiare also i might not even be able to attend or show at maker faire as i have a very critical final on the 22nd the day after maker faire i just got in the hall effect sensors and the rare earth magnets so i will need to implement that code into the program as well summer is coming up on 5/25/2017 then i will be be back to the green engineers stuff however i will need to take a summer class and might do a internship to get some money to get a small place to organize my stuff again thanks for your patience check bellow for pictures
