Three Years Counting Mold Hell

Inside of moldy wall

Half of this I’m still not sure on. Ie specifically what bugs/mites. The black cat (Cosmos) lived at my parents and had been my buddy since 8th grade (01). In visiting during his final days I was sleeping next to him where ever he wanted. This often meant the basement floor.

40 inch beaver (ubuntu 18.04)

here you see a 40 inch beaver in 4k (phrases not to google at work or at all(40in)) It wasnt perfectly straigt forward but I eventually managed to get Intel’s ClearLinux (playing hypervisor/kvm host) to let Ubuntu 18.04 take an nvidia 1650 with out the ACS override patch. 

This article is a work in progress but im going to try to put some roughly formatted things that worked for me before i worry about making it pretty

Clyde Rabbit

Clyde Rabbit 1
Clyde Rabbit 2
Rip Clyde.
Clyde Rabbit 3
Clyde Rabbit 4
A late friend of mine. Bonnie and Clyde came into my life in 2007 or 8. I never intended to own rabbits but I loved them dearly. I miss them every day. I lost Bonnie Nov 2018 and Clyde May 2019. My psychopathic parents have Bonnies ashes and have pretended to lose them to terrorize. I cant go there to write the rest of this right now.

2 hotels, 4 houses, 7 apartments Id argue Clyde was one of the most well traveled pet rabbits to ever have been. One hotel he visited I mistakenly fell asleep and had to sneak him out in the morning. When I woke He was on the floor looking up at me, nota a thing in the room touched/chewed. I hatched the plan of going to the grocery store near by and grabbing a reusable tote. way back in 07 or 08 I used to bring him and Bonnie to the 3rd floor neighbors in paper grocery bags so I figured he would tolerate the tote even in the car. What I didnt figure is broad sunny day going 80 down the freeway (Clyde on the passenger seat in tote) Clyde Wiggled out of the tote and rested his head on the center arm rest. 

he was amazingly bright. We could play tag/2 way chase. If i Turned and ran after chasing him he would bound along after me. In his first cage he had figured out that if one of the double latch system was undone he could let himself out. He would bite the bar above the door and then press it with his feet until it sprung outwards and he was free. in the decade plus I had him and Bonnie, maybe 3x did i forget food and water before going to sleep. not once did I not wake up to Clyde rabbit hopping on top of me or gently nibbling my finger then following me until him and Bonnie had what they needed. Im relatively sure he was aware Bonnie Had a tumor as well. 

When Bonnie died my parents had been in control for a few months while they banned me from their house (with elderly B & C still there) The day my mom decided Bonnie needed the vet was the first time in over 10 years Bonnie went with out Clyde. I got picked up from the hotel. Bonnie Died of fright to put it mildly. I held her until the vet closed. i think it was a friday. I knew clyde had to say goodbye. The pics where hes next to her were the following monday. 

when i brought him into the room he didnt seem to get it at first. it had been a 45min drive to the vet and I had to use the restroom. I came back into the room they were and found a single tuft of fur missing from Bonnie (laying next to her) he then took the position you see in the photos and didnt leave her side for 3 hrs.

When I rented A house in fargo with enclosed back yard.
same house, clyde does stairs
-7 he had wet his travel cage before we left hotel. My dad had fucked around till well past checkout wtih geting car back and lied about having it fixed. then took off and I didnt have a towl even to dry clyde in a moldy car with only one set of keys and no remote start

So I held him until he was warm and not as wet. Despite being 5min away neither Pail (Paul…hes yellow) or Marlene Wuethrich would answer the phone. I got arbies and ate it then suffered a nose bleed all while he sat in my lap. I had figured my best bet not being able to leave car on (no second key or remote start) not being able to leave 13 year old wet clyde in -7f car… go to pets smart and bring him in inside in my coat. As we pulled into that lot clyde again got on the center console. We sat warming up a little more and a mom and her daughter returned from shopping to the suv next to us. I looked up to see the random woman mouth “OH A BUNNY!” and grab her daughter. Clyde sat there with an ear turned at them looking positively majestic. Middle of the day/broad daylight petsmart parking lot in Maple Grove center arm rest of a car two strange humans staring at him. In petssmart he even took intrest in the birds as we walked by.

If you havent had or been around rabbits this probably doesnt hit home how it should. They are prey animals and normally this would be absolutely terrifying. Clyde wasnt shaking or showing any signs of fear. Clyde was an incredible rabbit. Bonnie was in her own ways as well and I will post on her soon. Bonnie could tollerate a lot with both me and clyde present but I would often see her hyperventilate say around my cousins kids/just never felt as safe. I hope that wasnt anything I did or didnt do to/for her. I never ment her to be second fiddle.

together even the vet and vet techs at the last place they called doc… had commented that they had never seen rabbits so calm.

Lithium Ion Pack Spot Welder

This is a write up on an early but working design for a CD Spot Welder. Its fet switched and electrically isolated with intent of actually being able to control all electric fab processes. The weld energy comes from a bank of Maxwell super capacitors. 

I needed a large quality lithium ion pack. Part of that is high quality cells properly joined (a bms being the other liability/safety component). China cells or packs featuring cells with fire right in the name seemed like too much truth in advertising and american made either comes with limitations like requiring complicated battery auth with bms or $. So I decided on assemble your own from sourced cells. This isnt meant to be a post on pack construction though. I will probably publish one at some point because a lot of the YouTube community and especially ebike community scares me speechless when it comes to litium ion pack construction.

Lawn Tractor Snowplow repair & upgrade

Lawn Tractor Snowplow repair & upgrade 12

I needed a space to use my welder. Im mainly in need of a new electronics work bench and server rack. Last year i picked up a Northern Tool Klutch 140si on clearance for a hella deal. I found a guy with a pole barn who also needed some help with his lawn tractor plow on its last legs so for that and improving the workbench in barn scenario I should get to produce the bench I need for my shop later and what ever else inbetween. 

heres the story of the lawn tractor/snow plow upgrade and revamp:

Fabing PCBs w/Custom Made UV Lithography Rig

One mans advernture into emulating industry standard pcb etching processies at home:

Why and how did I end up wanting to make boards?

For years I have done small business and residential I.T consulting. I stopped counting for client pc/workstation builds at 30 maybe 10 years ago. I had an internship with a university where I managed their MS Dynamics Teaching Lab and had converted it from 10 optiplex to 3 rack servers with hyper-v in 09-10ish. I started CS and went MIS then IS (changing universities) and somewhere in between I wanted to learn more about the CE/EE side of how code runs on the actual hardware.

over the years I slowly accumulated bits of that knowledge. probably starting at age 12 or 13 when I passed the Technician class Ham radio license exam.

One day I got the urge to bring to life a few hardware ideas I had. I decided that because i have no formal pcb design edu but had a stack of plexi left by old roommate…. being able to rapidly prototype would be essential to cost effectively learning pcb design and possibly developing products.

Routed Static Block With PPPoE & OPNsense

Centurylink PPPoE, Routed Static block & OPNsense

Routed Static Block With PPPoE & OPNsense 13
Yes motherland non soviat bandograph meter u in skew

If you are just getting started with Opnsense or first time with a static block This post is for you! When trying to figure this out a lot of form posts said it couldn’t be done this way and to use 1:1 NAT; so maybe even those around the block a few times will benefit. 

This post is a somewhat how-to for setting up a static block with routing on opnsense over pppoe with a modem in transparent bridge mode.(vdsl2 & centurylink) This Assumes you want to end up with a NATed DHCP Private LAN and a DHCP Public ipv4 routed LAN. Buckle in!
