Super LED Blinkenator 2000 (never ending story edition)

I’m still trying to make this darn thing solderless….and, I have possibly a lead, which ain’t cheap…but will allow me to offer two versions.

Those gold things are pogo pins. But, slightly less common ones with a 1.2mm diameter pin part. This should sit quite nicely into the Next’s 1mm holes in J15…..except in my excitement, I forgot about that darn keyboard connector!

Using these requires yet another redesign, but a relatively minor one that only needs the connector stuff soldered on the reverse of the PCB…

On the plus side, this could make end user fitting of the inserts a little easier 🙂

As for ‘expensive’ – those pogo pins are around £1 each and at least 6 will be needed, more if the wifi relocation is used!

Moar Heroquest!

Painted the secret door tile.

By painted, I mean, found some old brown acrylic paint, mixed a little dried up acrylic white pen with some alcohol ink and Formed a browny grey.

It’s a 5 minute bodge job, but good enough for the trial. Now to decide to keep all the filament prints I’ve made, or, junk ‘em and switch to resin….

Soooo much more detail!

Nerdy Stuff Part Deux – Heroquest

Used to love 90’s board games, and, as shown earlier, I fancy getting into Heroquest again…..But, NOT at the prices it’s fetching on eBay currently.

There’s a LOT of stuff to find out there, and more than enough to be able to fully re-create the whole game yourself.

BUT, as always, some of the things I’ve found, don’t really do it for me, so….My first in probably many…..A better Heroquest ‘Secret Door’ Tile….

Took some creative liberties with the door design, but there’s no way the printed tile can translate properly to 3D space unless someone has a particular wall height in mind….

This is just a merging of two other things found on Thingiverse, it’ll be a while before my organic 3D modelling skills get to the level needed to create the above from scratch

Now up on the Thingiverse – HERE

HOW TO COLOUR YOUR KEYCAPS…and to contact me

Firstly, if you’re interested in a kit, reach out via email

KEYBOARDS AT BLEUGH.BIZ

you can also find me lurking around facebook, reddit, twitter!

Two brands have been successfully used to colour your keycaps

1 – Milliput Epoxy Putty – (Thansk DAN) Available here – amazon.co.uk/dp/B002CNEWAM

2 – Stucco K2 – (Thanks Vinz)
available in Italy.

For you English, This translates to “paste for interiors”….amusing that PASTA=PASTE…no wonder some stuff we ordered a few years ago in venice came a bit squdgy 😛

Use a damp cotton bud or similar type of thing to poke a bit in at a time and not get it everywhere!…leave to dry. clean up, then coat with some type of laquer or conformal coating if you really want!

Add Epoxy, then your mini can look like this

C64 Mini Keyboards – COLOURED LETTERS! (by end users)

Lots of pictures here, But looks like the latest batch of C64 Mini hackers are quite the clever lot. Batch 21 has been arriving around the globe, and look wot some guys gone done!

First email arrived early this morning – Vinz!, You’re a genius…..My jaw dropped!

Some explaination of the pictures…….

In photo 1, I used a ruler with double sided tape to solder switches as straight as possible

in photo 2 I used white putty to color the caps

in photo 3 I cleaned the excess putty

in photos 4 and 5 I painted the caps with matt transparent water-based paint, in this way the filler is protected

in photos 6 and 7 the work is finally done

Blinkenator – Slow going

Just a quick photo of me holding my Next up against a snowy scene!

And aaaaanother Beta!. Doing significantly more testing this time round

Still not quite over the roadblock for the solderless BETA, but have kinda proven that the ‘programminator’ idea doesn’t really work as well as hoped. BUT, i have proven that a simple 9 pin JST-PH connector – 1.27mm pitch will work – also known as a molex picoblade style.

Going forward, this will be the way someone programs up the Blinkenator. I’ll have another board – possibly included with every blinkenator to convert this to a standard USBASP style header, unsure yet, depends on just how easy I can make the 6 pin header up on the top right to access. would be nice if people can program it up with their case closed….we’ll see

I’m hoping to double down on the blinkenator over the coming weeks, still quite a bit to finalise with the code and the LED inserts!….fun fun.

and, yes, my small digression with the 90’s miniatures is actually a disguised learning excercise. My LED inserts have some fantastically small detail. i’m now learning how to use supports properly….which will dramatically speed up development time on 3D printed inserts. and, also provide a proper path / workflow to being able to get them injection moulded….IF the budget and interest allows. My early experiments however suggest, I may just about be able to achieve an injection moulding style ‘gloss’ finish with 3D printing….keep tuned in!

I’m a nerd!

Used to play Heroquest back in the day. For some reason of late I’ve been a bit nostalgic about older games.

Well, 2nd hand ones are very expensive, and , I’ve got a 3D printer and access to Thingiverse…..so…

Can you see them!

This is the first ‘fun’ thing I’ve printed, just for me 🙂 it’ll be the start of a large horde…it’s a bit of a rabbit hole this board game stuff.

Also, experimented a little with neon pigments as you may have spotted!

Batch 21 posted! – up to date with ALL orders

Phew, what a mad few weeks.

If you’ve paid for a kit or just keycaps or waiting on spare parts, it’s now posted.

Missed the Saturday run to the post office so sorry about that.

I’ve now a small amount of stock of keycaps and plenty of kits so I can relax a little and have fun printing other stuff for a change! Can you believe that I’ve run at least 6L of resin through the printer …JUST developing and then selling these keycaps, I’ve never printed anything else on it 🙂

Keycap production snapshots-lots of pictures

A quick pictorial ! on the process of creating keycaps.

Step 1, Recycle the IPA. Leave it standing for a few days, it settles, becomes clean! This is a month or two of settling. I now have about 4L left from my original 7.5L…not bad for nearly 10L of resin printed
Step 2. Print and drain! Leave like this for maybe half an hour or so to drain off excess resin.
Step 3. Scrape keyboard off the build plate
Step 4. Throw keyboard into a small bag of IPA
Step 5, throw bag in ultrasonic cleaner! BONUS step….put bottles of coloured resin in for a while to get them mixed well
Step 5a. Drain IPA off into settling container for recycling. Fill Ziplock bag with water and drain to bucket. Repeat again. One clear GPU can run under the tap!
Step 6 – dry and separate the keys! Then leave overnight in a box to dry properly before curing
Step 7 – ensure you agitate the vat well, scraping gently all the pigment off the bottom.
Step 8 – sorting! – visual inspection of each set to grade them A or B. Also, within the same colour mix batch I’m able to potentially make one good set out of two bad ones!

I’ve missed out a few pictures, but this covers the basics. Using a timer, it’s around half hour all-up per keyboard. Sometimes a little more if a print fails!

A failure!

Tried to make a ‘GOLD’ keyboard but need to research a little on how to keep the particles suspended. This one failed due to too much gold. It all sunk to the bottom causing layers to become underexposed and ultimately sticking to the FEP

This was supposed to be clear!

Also tried to make a crystal clear keyboard…unfortunately I topped up the vat with a tiny bit of the gold mix from a poorly labelled bottle I use f or mixing (I didn’t write any label!) I’ll give these away with a kit to the first person that asks 🙂

F Keys!

Quite late into development, I’d realised that the F keys were supposed to be a different colour. So, I add two sets of F keys to kits. Some early ones went out without the extras. Happy to send some out if you shout.
