I have Sage barista touch and think the best single upgrade would probably the tamp. What do you think?
Hi All just curious if anyone has any info on ME 342 in terms of how difficult the class is and what to expect from it, like with the exams and homework. Is it helpful to know any softwares for this class?
Thanks
Looking for a new board, on the site I'm seeing they are all around the same price, any difference between them?
Clicking the inspect button does nothing, so is right click and select "Inspect Element". Something is not responding to the request.
Hi, Hope coffee machine repair questions are ok here.
I have an Isomac Zaffiro espresso machine and recently the electric tripped with the steam on. The machine turns on, but it no longer heats and I have established that the heating element has died. I confirmed this using a multimeter. So, I purchased a new one, and have torn the machine apart to remove the boiler and get the new element installed.
The problem is, my heating element is completely fused to the boiler and will not budge at all when I try and unscrew the heating element using an adjustable wrench. I have since tried soaking it in penetrating oil, I have tried hammering it loose, and I have also put the nut in a (basic £20) vice and tried to turn the boiler with my hands. It won't budge at all. I understand that an impact driver may help here so I am going to try and get a loan of an electric impact driver from a friend and have bought an adaptor and 30mm socket to fit it and see if that can knock it loose.
That said, does anyone have any other good tips for me to get this off?
I'm not exactly the best/most experience with DIY and only have some basic tools.
If necessary I can take the machine to a machine repair shop or maybe even see if a mechanic can get it loose, but ideally I'd do it myself!
Edit: In retrospect this might be a question better suited to /r/mechanicadvice
UPDATE: I bought a cheap impact driver, a 1/4" to 1/2" adaptor and a 30mm socket. I attached them to the impact driver, put the socket on the bolt, turned it on and the impact driver worked it's magic. The bolt came free instantly and I was able to pull out my heating element.
Hey guys I need a little help. So I have this categorical array (which is supposed to be my output that I should predict after I develop my ML algorithm) which has two categories.. [0 1]. And my data set has columns - "features" which are also binary. Now, I want to find in each column/feature how many samples are 1s (one category) and how many are 0s? How do it do this? Thanks in advance
