More work on the A3010 last night - thanks to @WindfallNL@twitter.com's hard work, ZIDEFS now works on the Castle A30x0 IDE card :D
This improves the range of drives the Castle card will work with and adds partitioning support (because only using 502MB of a 2GB CF card is wasteful!).

Had the HackRF out again. RF power with the transmit amp enabled drops to near zero... turn the TX amp off and there's transmit power.
Looks like the power amp is blown :( That might be why I'm having trouble sending DVBS streams to the NDS receiver.

The final production model for the @PatersonPhoto@twitter.com developing tank spool loader is now available at:

Free to download. OK to sell (with attribution). You can also send the file to a 3D printing postal service.

My @PatersonPhoto@twitter.com one-handed reel loader prototype is working well. I'll make one mod then publish the design under Creative Commons.

Anyone who feels they have a physical disability/impairment where this would be of help can DM me and I'll print and ship one for free.

Trying to prove a point to my parents:

Like if you've met amazing friends online that didnt turn out to be creeps or stalkers.
RT if you've met them in person and they were exactly who they said they were.

Bonus: comment how much time you've been in an online community

apparently @thalesgroup@twitter.com wants to kick amateur radio operators out of the popular 2m amateur radio band so they can use it for aircraft and drones. this is not a good idea. https://www.f4fxl.org/2m-amateur-radio-band-endangered/

Does anyone have a BSDL file for the Acorn "IOMD" (IOMD20/IOMD21), or a copy of the Boundary Scan section of the IOMD Functional Specification?
I'm trying to fix a RISC PC motherboard and access to the IOMD's JTAG boundary scan port would save me a lot of work!

Hopefully my act of staving off boredom while sat on a number 60 bus helped out a few people!
I learned something too. Had no idea Keighley station had enough space an track switches to turn a Class 333 train round.

I see @northernassist@twitter.com stopped answering people at about the same time I started replying to their angry customers with "hey, here's an alternative route which might help you?"
Their customer service is as good as their rail service! 😂

Omg there’s someone in a fursuit at work today

It has I2C too!

Been doing some more Acorn repairs and upgrades. The A3000 now has 4MB of RAM and a serial port upgrade! :D

The scam that keeps on giving. They have a re-opened pre-orders on the Atari VCS. They have already taken $4 million and delivered nothing. This thing was supposed to come out in 2017. https://venturebeat.com/2019/06/10/atari-shows-off-latest-design-for-vcs-game-console/

Everything was on default settings except I'm using a HackRF instead of a BladeRF.
I'm assuming changing the code rate isn't the correct fix - but what is the assertion trying to tell me?

@drmpeg@twitter.com I've been trying dvbs_tx.grc (from Gnuradio gr-dtv) and the Inner Coder threw an assertion failure and aborted:
(d_noutput * d_k * d_m) % (d_ninput * 8 * d_n) == 0
Setting the Inner Coder's code rate from 7/8 to 1/2 got it to run, but the IRD wouldn't tune the signal.

Not to sound cynical, but the "cover-ups" are already happening. NDAs in these situations need to be strictly regulated or banned entirely. || BBC News - NDAs: MPs call for ban on 'gagging clauses' over 'cover-up' fears https://www.bbc.co.uk/news/uk-48590038

Transmitting DVB-S with a HackRF tonight. Shame the satellite receiver doesn't appreciate my efforts...

Long story short - the external IO works, but the IDE and floppy interfaces are completely shot :(

Anyone got a spare FDC37C665GT Super I/O chip? My RISC PC seems to need one :(
