Anyone with experience with CAN bus + Teensy 3.6?

I have been recently messing around with the Teensy 3.6, of which the MK66FX1M0VMD18 it's rocking is probably one of the most powerful microcontroller I have ever messed with. (180MHz ARM Cortex M4, 256K RAM, hardware FPU, far more than enough GPIO, and an insane amount of serial interfaces!) I am particularly interested in the 2 CAN bus interfaces that it's sporting. However when loading the example code (which explicitly states it is only compatible with the Teensy 3.6! as only it has 2 CAN busses) I have not had much luck getting it to work. I don't really understand what CAN_TX and CAN_RX are suppose to be. I would assume it is simalar to UART where TX is connected to RX and RX is connected to TX. However at least with the MCP2551's I also ordered, the RX (on this chip) is actually an output while the TX appears to be an input. As it turned out, I was not able to use this chip due to it being a strictly 5V logic component. So after having discovered that, I decided to just connect the TX of CAN1 directly to RX on CAN0, and vice versa. Using the Object Oriented CAN example, I get absolutely nothing. If I swap the connections, connecting the low-impedance TX to the other low-impedance TX, and RX to RX, I also get nothing, but if I bring my hand close to the wires, or touch and feel around some of the pins, I will get some packets through and to appear on the serial monitor, almost as if one of the pins is acting as an input and of course it's floating because I don't know which pin that would be, as there is no code or comments to indicate such a button. I honestly have no idea what the hell is going on, and don't have access to a proper scope to see what is going on.

Can a board be bypassed? Answered

My sewing machine (a Pfaff 1171) dies after about 10 minutes. When I push on the peddle again, there is nothing... no hum - absolutely nothing. The light stays on.  Wait fifteen minutes or so, and it runs just fine...only to repeat the cycle.  Turning the wheel doesn't change the electrical situation.  It's almost as though a fuse is blowing and then resetting itself. I took it into the shop, and the verdict is that it's either the peddle (unlikely) or the board inside.  The board is no longer made.  If I turn the wheel, everything works... forwards, backwards, stitches and all that.  It's a great machine mechanically,  and I hate to lose it because of some glitch on a board.  Is there any way that a board could be bypassed?  I can survive without a bobbin sensor and being able to set whether the machine stops with the needle up or down.

Can these batteries be salvaged? Answered

I was given these two Gel batteries but they are not taking a charge. Is there some way to recondition them so they can be usable again? These were installed in a solar cell  and wind generator remote radio relay tower. They were new when put in. The wind charger was at first hooked up wrong (Not me who did that) and the batteries kept going flat until it was corrected. They did freeze once but after being pulled and brought inside they took a charge and worked just fine. They only had a few months of operation when the tower was blown down and the project was scrapped. The batteries and all the other stuff went into a store basement. Now, 2 years later, I am given these batteries but they will not charge. I don't know what might have happened to them in storage. Physically they are in perfect shape. I left one on a battery charger for 1 1/2 days and its still dead. My meter does show it has 10.3 volts across the terminals but there is no real amperage. The other one I put on a better charger and set it to recondition the battery. It ran for 24 hours and that one is also still dead.  These are sealed, non spillable, maintenance free batteries. Is there any way to bring them back from the dead and get them working again?

Soda can as crockpot rack - clever reuse or poison? Answered

I like to roast meats and poultry in my crockpot, but they often wind up stewing in a pool of grease at the bottom. I'm thinking of putting a washed, crushed aluminum can in the bottom to lift the food. Is there any danger from the can or inks on the outside? Sure it's foodsafe in its normal usage, but that doesn't include heating or food coming in contact with outside surfaces. Any chemists or metallurgists care to weigh in? Thanks!

Can I fix this? (Update!!!!)

Ok guys... I really need some help, I know there are some motor-heads around here on the forum, I really need some help from people on here with metal working/motorcycle/general small engine knowledge!!! See umm... yesterday, yeah well look at the pictures.. and trust me, my body is almost as mangled as the bike in the picture. I don't stop for NO ONE though, I want to fix this as my dad is pretty pissed about it (this weekend is father's day and he was looking forward to taking it out for a drive). Not only that.. MY BIKE IS TOTALED F?CK! I've done some googling and I can order some parts from the baja powersports website, as they have a parts catalog and even pictures to go with each part they sell, the weird thing is that they have like ALL the parts I could ever replace on the bike... except the front suspension.. like seriously everything under the kitchen sink EXCEPT any major front end parts (like said suspension)... Anyways guys, can someone PLEASE help me out here? I called a number on the baja powersports website and the guy said they don't directly deal with parts (even though it said it was a Canadian toll free parts number) and he asked for my postal code and found the closest "shop" next to me which is about a 30 min drive from here but oh well, I need the parts! Anyways look at the damage, it's pretty screwed up as you can see in the picture. But I want to know if maybe I can errr "bandage" it up a bit until I get said parts. The rim is kinda bent too... but I think it'll still roll forwards, I have the front end back together, my the left side sheered right off the bike and that part of the suspension will have to be replaced aswell.. Long post I know, but I'm a bloody hurting unit today, and my dad is very pissed off with me, this is a BRAND NEW bike guys! Surely someone can help me figure something? UPDATE>: After playing some phone tag and talking to A LOT OF PEOPLE over the phone, I'm getting like $500 worth of bike parts shipped to me within one business week, RIGHT TO MY DOOR! I'll tell you now when I hung up the phone with the guy, I nearly jumped through the ceiling, it's all gonna be covered under warrenty, even the shipping!!!!! I told the guy I'll be thanking him until next year! So all in all, my knee is still buggered up, but I'm a lot happier knowing that my 2 month old bike isn't a COMPLETE write-off! Thanks for the help anyways guys.... oh wait what am I saying, thanks for the criticism! But all in all, thanks for being by my side to laugh at my foolish mistakes fellow instructables members... I hope that everyone that reads this topic will see this and learn to be more responsible when driving ANY motorized vehicle!

Electronic Toolkit

I do some work with the FIRST Robotics kids and it is amazing to see what they are doing.  Big problem though seems to be a general lack of electrical test equipment.  They don't really have the money to buy oscilloscopes, function generators, CAN and I2C analyzers.   So I got one of the M3 Discovery boards from STmicro and it is really cool.  It has four 5MS A/Ds on it plus a whole host of other features(CAN, I2C, Serial etc.). http://www.st.com/web/en/catalog/tools/PF254044 So it got me thinking. Why couldn't we turn one of these chips into an "All-In-One" electrical toolkit and keep it cheap($50-$60, BOM ~$20).  It would be fairly easy to turnkey. I threw together some simple specs, what do people think. 1) Will supply general use drivers so a user can use the app or write their own. 2) Oscilloscope   a. Two Channel     i. 2MHZ of Analog Bandwidth per channel     ii. 10MS/s per channel     iii. Trigger on rising edge, falling edge, on-command, run-stop actions     iv. Datalogging for extended time periods at up to 10hz per channel (data stored directly to console),  maybe higher rate will  just have to see 3) Serial – 2 Ports   a. Multi selectable protocol w/slew control     i. RS232, RS422, RS485 4) CANBus – 1 port 5) I2C – 1 port 6) SPI  - 1 port 7) 8 Discrete User Selectable 8) Function Generator   a. Two Channel      i. 1MS/s small signal change      ii. 250kS/s full range change      iii. 0-3.3VDC buffered output  9) PWM - 4 Channels

Can Google/Youtube's filter bubble can be reset or eliminated?

I don not know how many people know what a filter bubble is, but I'll explain: A lot of websites (particularly social networks) remember the websites you visit, the stuff you see, and the stuff you like, and based on this they suggest other stuff you maybe like. Google and many other websites try to make a personlised internet. This sounds great at first. But this is a problem. For example, after I search a lot of music on one day, then try search something about elastic bands sizes, guess what? Google sees the word "band" and because of this only suggests music bands. It gets even worse when searching for opinions about news. You only get the opinions you already agree with. But I dont really do that so for me that is no problem. Is there any way I can re-set all personlised options for a website? It is not really a problem, there are more worse things in the world. But it is just annoying. If there is a way to fix it, I want to try it. Thanks for your attention. -Tnod
