My tabletop circular saw for cutting PCB material and whatnot has finally arrived!




It's got everything it must have, including a vacuum hose attachment.

Just like the mini drill press, this saw is clearly built down to a price, but at the same time it was designed by someone who knew how to do it properly so as not to compromise the actual usability and allow for an easy repair and upgrade, should it be needed.

I've already cut some boards, and oh boy, what a vast improvement over doing it by hand, you can't even compare.


The PSU is quite a brick -- at least on the outer dimensions -- and notice that they used a generic case sold for DIY stuff, suggesting that it's manufactured in small batches. I haven't yet looked inside it, but probably I should. It didn't blow up on first use though, so it should be fine I guess.




p.s. the sticker on the saw case says "rated power: 96 W", so no, the motor is not a 240 W one, but that's fine and is enough for small hobby stuff. You wouldn't want to use it for thick wood or metal or any heavy work anyway.


up: 5200 RPM on the saw disk without load. The sticker says 5000 RPM. The motor is nominal 12000 RPM (I didn't measure it).

Just brought home a HP 7550A Plotter. The mightiest beast in pen plotting aside from the stylish 7580. Only thing missing is the paper holder for the backside. Anybody able to make some pictures of theirs so I can DIY my own?

I also now own a Deskjet 650C I still need to get new cartridges for.

Executed some instant buys on Wandel&Goltermann SNA-62 and 7 Service Manuals. I only wanted the former with the latter being a bit of a panic buy as I thought it would be the only one the seller will have for the single digit SNA range. As far as I know they share a common digital and in part analog base with only the downconverter inputs differing from each other greatly.

I will scan these if possible. There is no digital resource for these anywhere.

This picture isn't from me, but might help? Taken from a Kleinanzeige offer (unfortunately already sold).
Try searching for "HP7550 Zubehör" and you might find better ones.

Damn did that sell recently?

Could have sworn I had seen that tray several days ago somewhere.....

Edit: I have the fitting auto paper feed tray and that one looks like it will fit there too. It has the correponding tabs at the back fo match the plotter's backside also.
        Anyway I will have to take it apart, clean and reassemble anyway. Paper feed is acting up and the take up motor for auto feed doesn't move at all.

buy now  or bye for now - this evening I thought I'd take a punt on the attached maths book for my kindle, but it seems I'm now out of the loop. 

[edit

well I think I got the wrong end of the stick there - just bought and downloaded The C Programming Language to check if I was locked out - probably the maths book was not suited to my kindle device - minor panic over, and I have a cheap Kernighan & Ritchie to read instead  ]

These inductor kits were on closeout for $2.85 each. They looked cool so I bought 6

Here's another crazy one. I'm working on a Nakamichi OMS-7 CD player and I'm waiting on a drive belt from Germany. I'm thinking that I'm going to need a CD afterwards loaded with test tones so that I can check the CD player out when it's all back together.

I realized that I don't own a burner for CD's. I have two computers but no drive that burns a CD.

A couple of months ago I helped a friend move and he was previously an owner of a satellite streaming company. During this huge move, he was giving everyone all sorts of boxes of stuff he no longer wanted.

I remember two boxes he handed me but I thought that they were external hard drive enclosures. Not!

I dug them up and realized that they are two brand new external optical drives from 2012 and 2013

The part numbers indicate the drive the customer chooses to goes in them. Sweeeet















I was able to make a test tone CD with files downloaded from the internet

Should arrive on saturday.

Arrived as a kit, was assembled in 10 minutes.
For the function generator and the multimeter I used the Siglent rackmount kit, for the R&S generator I still have to get 19" brackets.
The same applies to the load and let's see what else I will install there.
The rack itself will be placed on the desk.

With the Aliexpress discounts going on I just ordered the following:
DSlogic Plus logic analyser
Andonstar AD210, 10 inch soldering microscope to finally be able to solder 0402 at home
About dozens of different Banana and BNC, crocodile cables and connectors

[shapirus]

Ordered a TinySA Ultra. I have near zero idea why I need it (other than it's going to be a cool piece of kit), but I know I do.

It's tricky to say if I bought it today, but FedEx dropped off another box from LCSC, primarily radial and SMD caps, with a few reels of resistors for good measure. The order took more days to transit from HK, than it did for LCSC to fill it.

[w.v.s.]

In the meantime, I've found a display unit at a reasonable price. 
According to the date codes, I found inside, it might be build in 1987. Prices for the new units appear rather steep, but I have to admit, that at least my old unit makes a pretty good impression, also when you look inside. Appears to be a quality Japanese device.

A new bench power supply, now with a few more features than my old KD3005D.

Not today, but Friday I bought a Bambu Lab X1 Carbon w/ AMS.

I have a (very heavily) modified Creality Ender 3, the OG Gen1 from 2018, that I bought back then to see if I'd even be interested in 3D printing. While I have my Ender 3 pretty well dialed in now, it was no small effort. The cheap Ender series are great but are considered DIY printers that requires a fair bit of work. I've spent more on upgrades than the printer originally cost (multiple mainboards, dual Z upgrade, direct drive extruder, etc.). It taught me a helluva lot about printing and I have no regrets, but now I just want to produce stuff quickly without much tinkering. The X1C is amazing in that regard (at 10x the price, of course).
