Roggee

Law building at Southampton uni.

The Faraday tower. Bands of grey mosaic tiles and black windows, stood on a pedestal that's smaller than the footprint of the tower. In this pic it's wrapped in blue mesh prior to demolition.

The chemistry building, another box of grey mosaics and black window bands. Here covered in scaffolding while roofing work was being done

The physics building. Another long lasagne of mosaic and windows

His buildings at Southampton uni are more like "cooked" though...

A view up a concrete column towards the square wooden grid of the nave cieling of Coventry cathedral. It's all delightfully modernist

The Chapel of Christ the Servant. A tall cylindrical glass walled room. The windows are supported by regular, narrow concrete columns.

A view of a cross suspended between red sandstone columns. The columns support a concrete ceiling with broad corrugations. The regular pattern left supporting formwork is subtly visible. Where the ceiling meets another arch there's an opening, and green light reflects through from the copper cladding on top

Yeah alright Basil Spence was cooking with this one.

Ah shit, this counts as an Internet Thing™ doesn't it :/

Current project is to replace the brains of that big PDU. It needed a recap, but once I did that the main controller stopped talking to the relay boards reliably :<

Anyway here's my code talking to it instead. Satisfying clicks and clunks :3

Be the evidence you want to see in the world 🤔

Just gone from 1.2 up to 1.6 today. I figured 400 microns was basically nothing but holy heck it hurts :<
Going up 1 mm in one go must be intense x.x

Sinning at Gloucester cathedral for #FursuitFriday
It rained on the parade after so I guess I angered god...

Angled photo of me, Prophet, Tobii, and Flynn in fursuit during the Gloucestershire pride parade, outside the cathedral. A secret person's face is hidden by a cat emoji.

#fursuitfriday #fursuit out with the gang gang at pride!

🍓 Hey everyone!

We are finally 100% done with Pat’s head ✨

Next up - handpaws 🥳

#furry #fursuitmaker #fursuit

I only have two cat pictures on my phone 😭 making up the numbers with a goose and a dragon I hope that's ok. Sending lots of hugs too 💙

Sounds like an invitation to fill the corners in with rainbow stripes if you ask me :3

Amazing, awesome work! The green eyes are very cool 💚 Looking forward to meeting him someday :3

How am I just now learning how cool Cov cathedral is on the inside o.o I'm gonna have to pay a visit soon

😍🥵 looking good~ :3 I adore those rubberpaws hoods too

Biblically accurate TO-92 package

Being called a luddite should be a badge of honour honestly. They smashed machines not out of fear, but to put pressure on the ruling classes. They fought for the quality of their craft and for worker's rights.

Forensic scientists tend to be light source enjoyers. Not sure they'd appreciate a source that cooks the crime scene though...

This thing has lost its marbles. Has no idea which outputs it actually has switched on and off, sporadically forgets to actually turn an outlet on when you ask it to...

Back on my ~enterprise grade~ bullshit

They're screaming their tinder profile into the void

Self test screen for the MPSC ASYNC DATA TEST CHANNEL B, running at 19200 baud passed. That failed last time

Self test screen for the MPSC BOP DATA TEST

Anyway we make it though the self test we got stuck on before, and get the BOP 🎶 test done too.

There's no "hooray self test passed!!!" screen unfortunately. You'll just have to trust me when I say it passed ^_^

I'll put the case back together in the morning 😴

Balls, forgot to use my obscure meme re the corroded crystal

The display shows the quick brown fox test pattern, but the data is on both lines now

Text on the display shows "Hi BSky this is Roggee :3" There's a serial cable plugged in to one of the ports.

🎉🎉🎉 looks like the receiver is working now. I was able to send data from my PC

Underside of the PCB showing two ceramic caps soldered under the UART ICs

Microscope shot showing a bodge wire running from one oscillator to the other

Oscillator setup is a bit janky. They've got load caps slung on the bottom of the board.

The crystal collection I bought from Maplin as a teenager let me down, no 1.842 MHz.

We can steal the healthy clock from the good oscillator with a bodge wire for now

Annotated photo showing the bad crystal next to the leaky battery before I took it off the board

Photo of a HC49 crystal can with green corrosion on the nickel (?) surface

Photo through a microscope eyepiece showing green corrosion at the welded seal on the crystal can

B side oscillator has its crystal sat next to the leaky battery.

Popped it off, the crystal has corrosion on it.

Looks like the hermetic seal is compromised, which will kill the crystal.

Phillips PM6616 counter showing 1.84330 MHz on its beautiful neon orange VFD

As before, but it's 5.17551 MHz now

Excuse to show off the gorgeous orange VFD on this frequency counter 😍

Checked the oscillators on the baud rate generators - A side is 1.8 MHz as it should be. B side is 5.2 MHz. Chippy is going way faster than its 28 little legs can carry it 🫨

Diagram showing how the clock input pin is connected by an analog switch to either the R65C51 as a clock generator, or from an external input via a MAX232

Excerpt from the Fakerscope manual explaining some of the available clock configurations NOTE: For SYNC mode operation this option should NOT normally be used. If this option is selected for SYNC operation a restricted number of Baud Rates is available. These are: 19200, 9600, 4800, 2400, 1800, 1200. A value of less than 1200 will result in a baud rate of 1200. EXTERNAL - Disables the internal baud rate generator and allows the timing for transmit and receive data to be taken from an external source, i.e. a modem via pins 15 and 17 respectively. SOURCE - Enables the internal baud rate generator to provide the timing for transmit and receive but in addition outputs the same clock onto pins 15 and 17 (TXC and RXC) such that some external device may be clocked by the same timing reference as the Fakerscope.

Turns out the clock can come from either an external input ‽, or from one of the 65C51 UARTs, used as a baud generator.

News to me, but modems sometimes provide external clocks. I guess that makes sense if the line has lots of jitter?

Annotated datasheet noting the signals present on the chip pins

Scope screenshot of the 1.2 kHz square wave

Probed round the UART again. The receive clock is there, but it's 1.2 kHz. Should be 154 kHz (16x baud)

A bowl with rice, cabbage, peas, and fish in a Thai red curry paste.

Something isn't sitting right about the UART being bad...
Datasheet says it can pull 1.25 W which is enough to be warm.
Needs more investigation, but first, dinner :3
