this was the week of podcast audio dramas for me. I will give you some you should catchup on.

– The Monster Hunters , 1970s kitchy van helsing like characters.
– Archive 81 , A kind of noir found footage thing. it is better than I am making it sound.
– Help me, A slenderman like story. I really digged it.
– Mars Corp , a kind of sequel to the bunker, reminds me of h2g2
– The Bunker, a kind of prequel to marscorp, distopian future radio program.
– Within the wires, a kind of self help tape by the people who bring you nightvale.

Those are the more off beat ones. Obvious things you should listen to like We’re alive, Welcome to Nightvale, The Black Tapes, Tanis, etc are not listed.

I started rebuilding my home server this weekend. I bought a cheapo pc at the mit flea market and started transferring my 2 terabytes of files and backups over to it. Setting up nixos on it this time over the old debian I was running. I have it mostly working and will post my config of it after It is finished. The acme config in particular is pretty cool as you can easily have it systemd restart your servers and do more complicated things like how you can work around mosquittos handling of certs. Hopefully this goes well and I can redo my remote server as well.

Been a while since I made a post. I started playing a game called Habitica. It is a good way of keeping yourself accountable for the things you need to get done in a week, and encourages you to do more. This is one of the mores. I put it in as one of my weekly goals to get a blog post done a week.

I saw suicide squad. I would give it 1 out of 1 stars. I really liked the characters but did not care much for the plot. It was like they took the script of a superman film and tried to apply it to these characters, it just didn’t work.

I finally caught up on all my podcasts and added a new one, [I/O Panel]. I/O Panel is a podcast of three it guys out in dc area. I met them at hope, they were some nice guys and not a bad podcast to listen to.

I also read the spiderverse comic arc on marvel unlimited. It’s premise is ridiculous but the actual comic was a fun read. I am starting age of ultron now.

Epaper display

Worked a bit on my fpga code. didn’t make any real headway.

Pcb printer

Worked on my name plate for my member storage at the shop. I will print it on the printer and dye it like this instructables link says to. I also plan to try using the laser to drill holes like this describes also instructables.

Cleaver

Designed a soldering station driver for hakko 907 compatible soldering irons and powered by my laptop power supply

  • Drove to mobile
  • Went to retro game night at mobile makerspace. I owned at frogger.
  • Found and bought this drok dc-dc converter buck regulator to build a portable variable current limited power supply. exciting. Still have to figure out a good way to keep it cool.
  • got my usbarmory in the mail. I forgot to bring my charger with me to work on tuesday. So I just installed xrdp and xfce on to the little guy and plugged it into the windows machine. setup internet connection sharing. and I was good to work all day. It is a very cool device.
  • worked on my back door lock. I think I got it so this will reliably trigger the lock/unlock trigger.
  • Drove back from mobile.
  • Had great idea for my instant messaging system. What if we used the phone as a document store! genius.

Worked on misoc this week. And got forked by someone also interested in porting it to my dev board. Played around with misoc and migen bits for a bit to better understand how the c code meshes with the generated fpga code.

Pcb printer

Tim soldered the spam board we printed. Tyler verified his snaps worked on his board that I printed. Monday I worked on ceiling the leaks in my acrylic bubbler chamber for several hours I am pretty close to cleaning it up. I ordered a heater off of ebay for 20 dollars it will heat from 30c-60c. I also purchased a stronger bubbler to agitate the solution better. Also on ebay I found a seller for scrap pcb copper, and got some. looks good. I built my bubbler after struggling many times to get the box to be water proof.

Spam

Tim soldered half of a spam board I printed at the shop, but got busy and left. Don’t know how functional it would have been. But at least the task seemed very doable with the board.

  • Started watching unbreakable kimmy schmidt, its pretty funny.
  • Dropped and picked up lotus from preschool.
  • Celebrated mathias birthday and went to saint patrick’s day.
  • Bought a cheap schlage door lock for my back door. It turns out it was broken. But it also looks like it will be fixable just need to hack on it some more.
  • Got my odb2 reader in the mail. I was able to clear the gas cap warning on my car. I also took it over to Raymond’s car and showed him what his warning was as well. What is nifty about it is my car doesn’t ever turn power off to the odb2 port, so the bluetooth radio is always on now. Something I could use to detect to see if the car is in the driveway or not. More to come.

Pcb printer

pcb printer worked successfully! I etched my first pcb. I then spent sometime and wrote a bash script that modifies our pcb geda files to make the board etches more reliable.

For giggles I tried to reverse engineer the cartridge drm chip. The 1.7 volt pin seems to be a clock at 1 mhz and the far 3.3v pin seems to be the data pin. I haven’t figured out anything more than that yet.

I spent a lot of time researching different etching processes and settled on making a bubbler container for my muriatic acid solution.

Working on fpga dev board. I have had nothing but problems with migen and misoc. I still can’t get my code to run. I am hoping to figure it out in the coming week.

Pcb printer

I am porting his microcontroller code to small dev board I bought on amazon. It was a success. I got the olimex tiny85 dev board. Soldered it up. Broke the usb header. Realized how much I missed tim… Decided to hell with the usb connector. I was just going to use my buspirate on it. Realized I left my buspirate in Huntsville. To hell with it I will just use my leonardo clone i keep in my bag. Nope huntsville too… I was frustrated then I remembered I used an arduino in my tardis project. I took it out and was able to get arduinoisp sketch on it. I then programmed the dev board or tried to for ten minutes. I realized the olimex t85 board has a reset test point that is disconnected from the reset pin. I just connected my isp directly to the reset pin and everything worked perfect. I can’t wait to test it on the printer.

  • Got second place in trivia at mellow mushroom.
  • Stopped by Mobile Makerspace and did some soldering.
  • Visited my sister at her work.
  • Spent way to much time looking at repraps. I really want one but as I always say “you don’t read!” Reprap mendel90 Prusa i3 Wilson Ultimaker all seem like interesting options. Although I think the wilson is a clear winner.
  • Researched making a garment printer for the shop.
  • Drove back to Huntsville.
  • Started looking at ev conversion kit.

Modified my color classic as a mystic. Powered it up and was succesful. It was awesome. Then I put the back of the chasis back on and i think I damamged the crt or the analog board. Not sure which. but it just makes a horrible noise when I try to power it up ): I will try to look at it sometime soon but for now I am just defeated.

I succesfully got migen and misoc building for my board. I haven’t been able to verify their operation via uart or flipping leds. But I am very close I think. I also fixed boards for next run of production.

Pcb printer

I spent about 10 hours or so and built myself a pcb printer from an e260d. I followed this guide. It was very helpful. Right before I left for mobile in the wee hours of morning I succesfully printed on a sheet of aluminum. I thinki I am just having a problem with timing the way the different sensors talk to each other.

Successfully generated -22v and +20v from our circuit as wel as having close to correct amp draw. seems our mistake is over. I started researching other pcb options given chinese new year is right around the corner.

Matt made me this super cool model. Dusty printed it and it looks awesome. I should have my color classic, lc575 motherboard, and apple cdrom drive in the mail next week! I also snagged a copy of a/ux to run on it. So I should be tribooting between macos, a/ux, and debian.

Tim and I have a working board. Well I think we do. Electrically. It doesn’t seem to produce power at voltages I need, but I think it is because I am not driving voltage to it the right way. It turns out I was driving it wrong. I was able to get +22v and +15v out of our chip. Something is wrong with the feedback loop though and the negative voltages are wrong. Hopefully tim and I will bread board one for next week and move from there. I also started porting lm32 core to minispartan6. And by that I mean spent 10 hours getting their propietary garbage software going. Although once I get verilog generated from it, I shouldn’t need to touch it again.
