Abstract

alcoholics, for reasons yet obscure, have lost the power of choice in drink. Our so-called will power becomes practically nonexistent. We are unable, at certain times, to bring into our consciousness with sufficient force the memory of the suffering and humiliation of even a week or a month ago. We are without defense against the first drink.</p></blockquote><blockquote id="b97c"><p>~ The Big Book, page 24.</p></blockquote><p id="2733">I mumbled something about doing more therapy sessions to stay in touch with my baseline feelings, but my new sponsor was having none of it.</p><p id="e1c9">‘This isn’t an emotional issue!’ he said, cutting in. ‘This is a memory issue that no amount of therapy you chose to throw money at will solve.’</p><p id="1800">He even suggested that the mental blank spot could be similar to a form of amnesia or dementia that science hasn’t picked up on yet.</p><p id="4ad6">‘But why hasn’t science picked up on it?’ I asked, holding the phone tightly.</p><p id="26fb">‘Probably because this blank spot only happens at certain times. Most of the time, it lays dormant.’ he replied before warning,</p><p id="337a">‘And unfortunately, this dormancy feature gives us an illusion of power. We think we’ve got sobriety now because our memory and willpower function normally again. Until, the condition randomly comes back online, and we relapse, leaving us totally baffled as to why it happened.’</p><p id="a3e9">My new sponsor sighed deeply.</p><p id="f455">‘It’s heartbreaking,’ he said softly. ‘Especially if you’ve relapsed after being multiple years clean. But it is sadly needed to show you that you are genuinely powerless, regardless of how much you desire and want to be sober.’</p><p id="969d">My head was spinning. Every sentence felt like the jolt of an electric cattle prod.</p><p id="8e0a">Later that day, I looked back at my recent relapses. I found no real conscious memory of consequences before any of them.</p><p id="352f">It appeared relapse was happening to me, not by me.</p><blockquote id="8aba"><p>As soon as I regained my ability to think, I went carefully over that evening in Washington. Not only had I been off guard, I had made no fight whatever against the first drink. This time I had not thought of the consequences at all. I had commenced to drink as carelessly as though the cocktails were ginger ale. I now remembered what my alcoholic friends had told me, how they prophesied that if I had an alcoholic mind, the time and place would come — I would drink again. They had said that though I did raise a defense, it would one day give way before some trivial reason for having a drink. Well, just that did happen and more, for what I had learned of alcoholism did not occur to me at all. I knew from that moment that I had an alcoholic mind. I saw that will power and self-knowledge would not help in those strange mental blank spots. I had never been able to understand people who said that a problem had them hopelessly defeated. I knew then. It was a crushing blow.</p></blockquote><blockquote id="93f7"><p>~ The Big Book, page 41.</p></blockquote><figure id="7922"><img src="https://cdn-images-1.readmedium.com/v2/resize:fit:800/0*n4r4HuNFWSnCD_WU"><figcaption>Photo by <a href="https://unsplash.com/@alicealinari?utm_source=medium&amp;utm_medium=referral">Alice Alinari</a> on <a href="https://unsplash.com?utm_source=medium&amp;utm_medium=referral">Unsplash</a></figcaption></figure><h2 id="287c">A Belief That It Will All Be Alright.</h2><p id="baea">Sadly, the ‘blank spot’ wasn’t all that was happening.</p><p id="7c3e">My new sponsor later explained that something else was happening in my mind, a kind of twisting of my thinking that I couldn’t see either.</p><p id="02a0">This is the other main feature of the relapse condition.</p><p id="da70">The Big Book explains it as follows:</p><blockquote id="f067"><p>But there was always the curious mental phenomenon that parallel with our sound reasoning, there inevitably ran some insanely trivial excuse for taking the first drink.

A4988: Stepper Motor Driver Carrier + DoRobot

Allegro’s A4988 — Bipolar Stepper Motor Driver — 2A@35v peak — Ardu-Serie#53

This breakout board from Allegro’s A4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

JK 42 HS340424A

Warning: This carrier board uses low-ESR ceramic capacitors, which makes it susceptible to destructive LC voltage spikes, especially when using power leads longer than a few inches. Under the right conditions, these spikes can exceed the 35 V maximum voltage rating for the A4988 and permanently damage the board, even when the motor supply voltage is as low as 12 V. One way to protect the driver from such spikes is to put a large (at least 47 µF) electrolytic capacitor across motor power (VMOT) and ground somewhere close to the board.

Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble.)

Warning: I think it is better to never leave the pins MS1, MS2, and MS3 floating. In the video, I demonstrate why. Watch the video and see what problem I’m talking about …

MS1 and MS3 have internal 100kΩ pull-down resistors and MS2 has an internal 50kΩ pull-down resistor, so leaving these three micro step selection pins disconnected results in full-step mode.

Thanks for the visit. Take care:) Bye for now!
