Reorganizing lab 3.

Continued to work on the shelf in the lab.
All of the shelfs are sanded most of it finished (3 out of 4)


This week will be off from my lab, I have other, mainly office work related tasks. Hopefully next week I can finish this with the final assembly - but most of the cases, this is too optimistic statement. 😂

Burabu find

Today I was on Burabu (local hamfest).
Scored these things:







The Mean Well supply for 1500Ft (less than €4), and all of the other things for 10.000Ft (~€25).
I got those just for the enclosure or maybe the power supply.
Looked around. I found loop power amplifier for €877 on the internet. Most probably its real value is far from this. I just thinking if it can be sold online for substantial money, or just scrap it as I planned when bought it.

Terraform, AzApi, Sql Managed Instance, DTC and it's consequences

Something from my daily work (It is possible, that I will more about it as I see daily issues).
I got an assignment to enhance out Azure SQL Managed Instances Terraform deployment module with DTC (Yes, it is a good question, why on earth this outdated technology is still needed).
For the DTC you will need two resources added to your managed instance. One is the DTC configuration, the other is the serverTrustGroup what determine which of your managed instances trust each other for the distributed transaction.
As I not even surprised, none of the above exists in the Terrafrom AzureRM provider, so you need to use AzAPI provider for it.
The DTC setting itself is a piece of cake - if you have experience using the AzAPI resources you can easily handle it.
The trustGroup is a different animal.
Here you can find the Microsoft documentation for it: https://learn.microsoft.com/en-us/azure/templates/microsoft.sql/2023-05-01-preview/locations/servertrustgroups?pivots=deployment-language-terraform
You just add the resource and done...


resource "azapi_resource" "symbolicname" {
type = "Microsoft.Sql/locations/serverTrustGroups@2023-05-01-preview"
name = "string"
parent_id = "string"
body = jsonencode({
properties = {
groupMembers = [
{
serverId = "string"
}
]
trustScopes = [
"string"
]
}
})
}



Not exactly. The name, groupMembers, trustScopes are explained in the documentation. The parent_id is not exactly. The documentation said:
"The ID of the resource that is the parent for this resource.
ID for resource of type: locations"
What this means to you?
Usually in the Azure "location" is used as the synonym of "region" - here: wrong
Even, if it would be the region, where should it be located in the management group/subscription/resource group hierarchy?
Anyway, as a normal Azure resource, it should be located in a resource group. Ok, add the resource group ID there. The Terraform give back this error:
"Error: `parent_id is invalid`: expect ID of `Microsoft.Sql/locations`"
What a hack is this Microsoft.Sql/locations ?
Looked through the internet. Yes it is part of the object hierarchy of the serverTrustGroups but, as resource it doesn't exists.
Ok. Deploy the Trust Group manually. Done it. On the portal you can't see the JSON of it.
Try other way.
Try to get it back via AZ CLI:


az sql stg list -g <resource group name> --instance-name <name>


The result:


[
{
"groupMembers": [
{
"serverId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/<resource group name>/providers/Microsoft.Sql/managedInstances/sql-test-01"
},
{
"serverId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/<resource group name>/providers/Microsoft.Sql/managedInstances/sql-test-02"
}
],
"id": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/<resource group name>/providers/Microsoft.Sql/locations/West Europe/serverTrustGroups/trust-group",
"name": "trust-group",
"resourceGroup": " <resource group name>",
"trustScopes": [
"GlobalTransactions",
"ServiceBroker"
],
"type": "Microsoft.Sql/locations/serverTrustGroups"
}
]


Now, can you see?
After this, our code will look like something this:


resource "azapi_resource" "trust-group" {
  type = "Microsoft.Sql/locations/serverTrustGroups@2023-05-01-preview"
  name = var.trust_group_name
  parent_id = "${var.resource_group_id}/providers/Microsoft.Sql/locations/${var.region}"
  body = jsonencode({
    properties = {
    groupMembers = [for ServerID in var.groupMembers : { "serverId" = ServerID }]
    trustScopes = var.trustScopes
    }
  })
}



And I try not to judge the quality of the Microsoft documentation ...

Reorganizing lab 2.

After having hard time to remove the rust and the graphite covering from the iron parts during the week, Today finally I was able to put back the rust. 🤣

 
Just joking. I found redish brown base coating. 😉
I'm planing the black cover paint for tomorrow.

Reorganizing the lab 1.

Most of this years spare time activities went with other tings than electronics, 3D printing and my lab itself.
The result is an extreme chaos down here. A few weeks ago I decided to start to work on this.
The first was to dig out myself from the things around here. The second I decided to build the shelves on the top of my desks to generate some free spaces.
Bought everything needed. Wood panels, table legs (this will support the shelves), some iron profiles to reinforce the front of the shelves as I'm not willing to put support on the center front. Also want to reinforce the table legs as those has extreme wobbling.
The work begun. Cleaned two of my four desks.
The iron profiles are cut and drilled.


Next is sanding, painting those.

I'm back - Thingiverse



A few month ago I stopped to work on my hobby projects. I had many other things in my mind, changed my life a bit, restarted my photography hobby and so on.

In December I started to think about to continue my things, first in 3D printing, but not too much happened (I'll write about it later).

A few years ago when I involved myself in the 3D printing also registered an account on Thingiverse.

I published there a few things: https://www.thingiverse.com/suf/designs

After a while (not really remember exactly when) Thingiverse accused me with a copyright fraud and disabled my account. To understand, all of the designs I published designed by myself and not connected to any copyright protected thing, so I still don't understand why.

I took several attempts to recover my account - unsuccessfully, then I gave up.

Yesterday I got two notifications that somebody commented one of my designs and remixed it. It was interesting as I didn't se such in the last years.

Just tired to login. And miraculously it let me in.

I don't know what happened but I'm happy on it anyways. I just guess it has some connection with the recent events described here: https://3dprintingcenter.net/ultimaker-announces-a-major-update-to-the-thingiverse-platform/

Anyways, I'm happy with it. I feel that an indication to come back in many ways.
