‘Trading Card Dispenser’ control box - servo switch controlled [Part 2]

Back in 2022, I posted up about the electronics

for the TCD Control Box.

This was supposed to be THE new RC switch controlled unit, see picture.

Wrong RC switch [not a momentary one]

.....rather than the previous (and very successful it was too) remote controlled version picture here below.

original remote controlled fob version

The new RC switch that I thought was the correct one, wasn't a momentary version, but an on/off one.

Momentary RC switch

So I had to get a new RC switch, from Model Radio Workshop.

The above switch then links to a (original design) micro voltage regulator (seen in next image) and an adjustable automotive timer (orange)

• The single relay controller (from model radio workshop) has been designed to allow modellers to switch one item on and off (max current 1 amp).
• The unit also allows the user to select latching or non latching mode, so in latching once switched on it stays on until you trigger it to un-latch.

These have gone up in price so had to find another (cost effective) type of adjustable timer, (The timer unit is the orange relay in below picture).

Components List for a RC Transmitter switch version:

• Momentary RC switch from/or similar link to Model Radio Workshop: MRW06 Single Relay Controller Switch
• Adjustable relay timer: example here.

Components List for a Remote control relay switch version:

• Remote control relay: example here.
• Adjustable relay timer: example here.
• Voltage regulator, 12v stepdown version: example here.

The above two versions have different 3D housings (If you'd like this), these can be found on my Prusa account page, FREE to download and print.

I have now created a Facebook page,

dedicated for the

Trading Card Dispenser.

To help and for others to share their builds and modifications etc.

Event: Stars of Time @ Weston-Super-Mare

This coming Saturday, November 30th......

Just some of the droids [from our last attendance] will be joining us this Saturday.

The Mandalorian: R5-D4 trading Card '88' : version No4

Card 88, Gold version, no4

still waiting on one more version to be delivered.

Trading Card Dispenser: WIDE version

December 2023:

Mike’s card maker, unfortunately, don’t always cut them to the same tight tolerance, so in the past I’ve had to trim them down to fit in the TCD unit.

This isn’t really practical lol so I decided to make a second WIDE version of the TCD to allow for this. I couldn’t just increase the size in Cura, as this would mess with all the other dimensions.

So the cartridge inside width was increased and the main body’s slot opening was also increased slightly.

I 3D printed off a full set from the files & assembled them, cannibalising motor parts & spring plate from an older model.

January 2024:

Testing the new version and it worked.

October 2024, I'll be uploading this version to my Prusa account in the near future.

Treadwell WED-15-77: Part 28

July 2024:

Here was to be the final instalment of the Treadwell build 😀

Recent work has been mostly focused on making the sledge to transport WED on, via the cars roof rack.

Sounds:

Needed to fit a speaker and wasn’t happy with my original position idea. So decided to fit in inside the ‘logic housing’.

Position located:

How to find the centre of a circle lol

Dug out this adjustable hole cutter. Think I last used this to make the holes in R5’s legs!

Making a start on the hole.

One hole cut out.

Speaker fitted with its spacer ring, that I had previously made for the GOID-4 messenger Droid.

Re-installed the ‘Logic housing’ (the hole cutter wouldn’t fit inside it).

I had added longer leads from it to reach the amplifier board.

Just need to finish off some connections and save some sound files. Keep forgetting these last two pieces. Needed to buy a proper servo controlled switch, similar to the one used in R5, but this ones a single and much smaller.

Another tweak, was the addition of a volume (potentiometer) to boost the sound. When I couldn’t hear it at Mshed event, I knew I had to install one.

3D printed the knob from a file on the Prusa printables website.

Had to rewire the signal to volume dial to amp to speaker wires.

Claw arm servo:

The new micro servo arrived sooner than expected lol, but I had already started on a modified 3D printable housing to fit a new metal geared SG90 size servo. It didn’t take up much more space , but i had to reposition the securing screw, and add a second one.

I used brass knurled threaded inserts & M3 screws.

I made a slot in the side to allow the servo horn some freedom. This once finished, could be covered.

I needed to add a slot in the claws tube to allow some flexibility for the wire that connects to the servo horn.

I also added a location hole for a screw.

Next was to remove the servo plug so that it could connect with the servo lead.

Almost forgot about painting it…..

Primer applied after some sanding.

Weathering:

Dug out the paints and got to adding brown, yellow and ochre.

Then black to give the dirty oily look.

At the Mshed event, I was asked by some of the builders if Tread was metal construction, they were surprised to hear the upper section was all 3D printing.

Upgrades:

I know I said this was going to be the last post on this build, but I have a few more tweeks to do with things I wasn’t happy with, so there’s more to come.

July 25th…….

Wheels:

The original wheels were spaced away from the base, as can be seen in these two  photo.

original deleted scene SW ANH

remade version for the prequals

    

So I decided to draw up some spacers and 3D printed them. This along with some more substantial axle bushes with bearings in, to better support and properly align the wheels. And finally, some new axle's at over 180mm in length!

Events Media display unit - idea

August 23rd 2023

Having the huge tv screen at our Mshed event, reminded me to sort out a smaller more portable unit for other events.

And the best reminder is when your works IT are scrapping off old (but still good condition) flat screen monitors. I grabbed two the same and that  used standard power cables. I also grabbed a mini PC unit…..but again, no power unit.

Next came the ‘how to??’

Internet searching for power cables led me to smaller media units like the one I was able to purchase off eBay for a tenner (£10 GBP).

I needed an adapter from HDMI to VGA to connect to the monitor, again, off eBay for £5.

Once all connected up, I got this…

And that’s as far as it got. Played around with different ways to access the video, but my suspicions were confirmed when I messaged the seller about the video not playing. These are old devices and they don’t seem to like the newer, faster, more advanced video types. He made some great suggestions on how to attempt to convert to a usable file. So I went online and used video a converter to hopefully a more usable format.

3D printing - Jake Lunt Davies (Part2)

Last week (December 2021), I finished off the lower body of the GONK, as well as creating the unseen sides.

Now, I’ve not drawn this to scale, but by eye only. When it came to 3D printing, I decided to print it at 50% half scale. To save on material and mostly time, as I wanted to see it lol.

Here's the link to part 1

Here's the link to the 3D model I created.

Magazine article about building my R5-D4 (......back in 2018)

Back at the end of March 2018, a fellow builder, Nik H, who happens to work at a magazine publishing company, asked if I'd be interested in writing a piece for his editor. He's proposed the idea to her and she was very interested in it.

Good Woodworking magazine

lol

The Woodworker magazine

So I started writing how I went about building R5-D4 out of wood. Trying to condense three years plus work & to simplify it down to 500 words was a definite challenge lol. I also sent in photo's of the build.

.... unfortunately tho, this didn't get published.

October 2024:

I do still have the transcript, so I may post it up one day lol.

Social Media for updates and more 2023 -> 2024

April 25th 2023

(updated October 2024)

Its been a while, but R5’s back on Facebook 😁. (2023)

Since Google+ ended, Blog notifications ended and so did the amount of visitors to this site. I do Tweet 😂 and of course have my YouTube channel. No adverts as I’m not here for the money lol, just entertainment/knowledge/help.

So to keep up with what’s happening in R5’s world of Droid Building, I would say you can follow me, like, subscribe, search up 'James R5D4'. And any questions, comments, feel free to post up or DM me if you’d prefer.
