Out of Office – from Cool to Hot – Vacation Post!


Over the last couple weeks I’ve been playing around with my newly designed Cold brew controller, and I have to say … I did a pretty good job with the initial design! Though, I’ve already been working on a revision to fix some minor issues that I had not foreseen (mostly due to with the intricacies of the ESP32 board).

DropBOB Interconnect board – CoffeeMkr PRO Beta1


So I’ve finished the design of my interface board between the ESP32 and my Cold Brew Coffee Maker PRO. It was mostly complete a little while ago, but I had not yet done the design checks for this new awesome service I discovered. I was searching for a simple and affordable board printing service. There are a bunch, I know, but I really do like this one: dorkbotpdx.org which runs their orders through oshpark.com.

Post "New Job" Update


Sorry I haven’t updated this blog in a while. My new job has kept me quite busy … some days working 12-hrs. Mostly just trying to get myself up to speed as fast as I can. Soon I’ll be back on regular shift.

In the mean time, enjoy this Art wall update:

Unemployment week – Projects and cleanup


So, this week I’ve been pretty much at home the whole time (sorry for the long post, I’ve been pretty busy). I’m transitioning into a new job and left myself a week in between to take care of some loose ends.

The first thing I did was get myself a haircut (and bubble tea). I really needed to get rid of the dead possum on my head. I think It looks much better, but don’t ask Jenn about it … she’ll just say: “meh”.  Either way, Jody did an awesome job! She’s super nice and very friendly. Its not an upscale salon like what I used to go to in downtown, but I don’t really miss that either. I kinda like that it doesn’t take 1.5-2-hrs to cut my hair.

After that, I decided to clean-up my room. You can see a before panorama pic from before. It was a real mess. I even got fresh banana-bread muffins from Jenn for doing that. Score!

After cleaning up the room, I routed all the wires for my computer/entertainment-system back to my TV in the living room. This is where the internet comes in too.

After making a 3/4″ hole in the wall using an extended wood drill bit (of which I lost the set screws for the extender in the wall … stupid wall), I proceeded to thread the wires into the wall. I’m going to clean this up in the future. Right now I just wanted it to be functional. Maybe next week I will place a 1″ pipe with bushings so that it looks nice & is functional. Watch for a future post on this.

Now for my desk! I’ve been eager to start this part as having a functional workbench is the most important part of a work-space. I’ve had this idea of a 2×4 work-desk that I can replace peices of if they get too damaged. This was basically the same procedure as building yourself a deck. I even used 3″ green deck screws. The hardest part here is not having a bench saw. My angles were not a perfect 45 degree. But with my advanced hand saw skills I managed to make this work.

The idea is not to make a perfect “Ikea” desk. I want something robust that can take a beating. I don’t want to be worried about having a dent or scuff in it.

Now here is a short PSA for any of you following along and using power tools. I am not a professional, I do this for fun, so safety first! Sawdust = P95 dust mask, Loud noise = Hearing protection, Flying bits of wood = safety glasses. Be safe and don’t try this at home … Unless you know what you’re doing.

Here’s the finished top part. I decided that I needed a little clean-up session right after this as the house was getting really bad. It was actually worst that what our hedgehog leaves for us every morning after her drunken nights out.

Once acceptably clean, I started on the legs for the workbench. The legs are made from cedar ($$). I know, I didn’t need them to be cedar. So I bought these 4×4 cedar pieces originally for my gantry/Over-head-crane system. What I found was that cedar is an incredibly soft wood. I will need to redesign that system. In the meantime, I really like the contrast between the top & bottom of this table. It gives it an eccentric feel.

Love the accents of the cedar!

You can better see the chocolate/vanilla swirl that is my desk. In the above picture the legs are just placed on where they need to go. The process of actually screwing them in was actually quite complicated. I had to single-handedly lift the entire portion and delicately place the tabletop onto some teetering legs. This is where my OH-Crane would have come in handy!

Once upright, I used some 6″ headLok screws. These things are awesome for this purpose. After drilling these into the posts I immediately felt the sturdiness they added.

Right after I added metal angle plates with angled 2×4 for supports.

Desk! Super happy with the result. This desk will be the production floor of many of my future projects.

Shelf Project – Industrial Pipe Shelf


Finishing touches: Cable management & Placing of things on shelf

I Finally staples the cables to the wall so that they are mo longer a spaghetti mess. I love when things are organized! This shelf is now useful & good looking.

I can even display my most ambitious Halloween costume to date: My Aperture Science Portal Gun. My first blog post is all about building this thing. You can look back and see it here: Day1, Day2, Day3, Day4, Day5, Day6, Day7. Ah, That was a good project! Thank’s Jenn for your support!.

Since Jenn hated my led strip on the TV (That’s so dumb Bobby). I decided to put it when it belongs (you know, what it was actually intended for). I placed it under the cabinets to give us a little more light right where we need it.

Turns out it does a whole bunch of funky colors. Even scary ones like red.

And futuristic ones like Blue.

But I know Jenn will only want me to use the white one … She’s my compass on a ship. She keeps me straight & going in the right direction! I love you.

Shelf Project – Industrial Pipe Shelf


Today I managed to complete my industrial pipe shelf project. We went to Home Depot. Purchased pretty much all of the “Black Pipe” that they had at that store and I even had to go to the next closest store and again buy out all the stock couplings that they had. I also figure that I might as well get some wood for my next project. All in all a good catch, about $400 worth for the next 3 projects.

4″x4″x8′ cedar for my gantry “crane” setup – (future project)

4 pieces of pine 12″x36″x3/4″ for the shelf

5 bags of fittings & other good stuff

LEED compliant packaging removal

4 castors – good for 500-lbs each … I’ll have a 1-1/2 tone lever hoist on this gantry

3/4″ fittings!

More 3/4 fittings!

6″ long 3/4″ nipples

The only tools needed for this project

holes all drilled out to 1-inch

Oh man these fitting are tight to fit in the 1-inch holes I just made … I would recommend to anyone to make them about 1-1/8″ instead (too late now for me) 

Here’s my jig for assembly

Fully assembled and half painted

 As you can see I added 4 brass couplings right in the middle. I had to do that since the second store I got to also ran out of these fittings. I substituted these 4 brass ones instead and I have to say, I really like the look it gives. These were $5/each instead of the $1/each of the regular ones.

Here will be its final resting place.
It fits perfectly

 I painted it with a white waxy stain that is super eco-friendly & has low odor. It is the same paint I used for the crib I build a few years ago.

Just perfect!

I love the contrast that the white pine makes with the black pipe … This is exactly the look I was going for!

You can find the CAD Solidworks files here: GrabCad–>Industrial-Pipe-Shelf if you want to add them to your project.

One last thing. Here’s our art wall all finished up. Finally got the rest of the magnets to put up all those blank canvases for our friends & family to paint.
