In mid 2018, I discovered that there was a huge community out there who makes/watches videos about hobby restorations and retro hardware. That's when I put 2 and 2 together, or rather my puppetry and my hobby: tinkering in almost all fields. Right now, my main series is called "Tinkering with Atkelar" and it features "mini-me" as a moderator and myself doing all sorts of projects: Restorations, workshop improvements, repairs... pretty much everything can be expected. Originally I created the feature puppetry skits that are both "family friendly" but still mostly for a mature audience.
Tektronix 1503B
Workshop Project #36 - Tektronix 1503B TDR
This one took quite a while to complete. Why would I need one of these? Well, getting into some radio stuff more and more recently, I thought it might be good to make sure any antenna cable is halfway decent at least. This unit seems to be still in use by several hobbyists at least, and there's quite a bit of modding info out there. The LCD display is a known failure point, especially the EL backlight. In this video, I do the usual cleanup and repair of the device, so that it does provide proper measurements again.

HP µLab - Take 2!
Переглядів 2,5 тис.14 днів тому
Restoration Project #51 - HP µLab - Take 2! Back in 2021, I did a combination repair and art project for Karpour. It was based on a found PCB from an HP 5036A µLab unit. These were training kits for the emerging microprocessor based devices. I'd say it might have been used in schools and for training professionals alike, since the training manual makes a few assumptions about basic electronic k...
Fluke 8375A DMM - Part 2
Переглядів 2,4 тис.Місяць тому
The Fluke 8375A is a digital benchtop multimeter, made around 1973. It supports DC voltage, /- 1100V as primary function and comes with a module to convert an equal range of AC voltage to an RMS value. As an additonal bonus, it also has a built in current source to measure Ohms from essentially 100µ𝛀 up to 12M𝛀; It does not have built in current shunts however, so current messurement would need...

Restoration Project #50 - Sinclair MTV-1 Back in summer of 2023, I finally scored one of these early portable TVs. You might recognize the different cameras that were used during the course of the project. Somehow, it got shelved after ordering the new batteries and I just recently finished it. Also... the name tag on the bench didn't quite work out as expected... works a bit better for live st...
Fluke 5100B - Part 3
Переглядів 2,8 тис.2 місяці тому
Workshop Project #34 - Fluke 5100B - Part 3 And now for the conclusion! Part one and two had the disassembly, cleanup, most of the recapping and first power supply tests. No magic smoke! So in this final part I start off with the "isolator board" and a quick function test of the first modules! The first tries are promising, so I use that to explain a bit about the overall concept of the device ...

Workshop Project #34 - Fluke 5100B - Part 2 After taking the unit apart, cleaning things and starting to assemble the case again, I start to do some recapping and replacing of thermal paste in this episode, leading up to the power supply adjustments and validations. A quick note #1: based on comments from part one, I did double check on the "RTC" (=real time clock) on the regulator board. It's ...
Fluke 5100B - Part 1

Workshop Project #34 - Fluke 5100B Now what did I get myself into now?! I was browsing e-bay and looking for some affordable - that is below 5 digit including delivery - solutions for reference voltages and currents; as in calibration refrences for my ever growing multimeter collection. So that they at least agree to a certain degree and are close enough to a real absolute value to comfortable ...

Restoration Project #49 - Loewe-Opta "Bella" I was hoping to have that project finished by now, but there have been... well... issues. The day job picked up again, and also there have been a few other projects. While waiting for parts, I kept busy with these in an interleaved fashion. The radio is a Loewe-Opta brand, "Bella" model. It has AM and FM reception (eventually hopefully) and features ...
Philips PM5705 Pulse Generator

Workshop Project #33 - Philips PM5705 Pulse Generator I keep looking for "odd" or "uncommon" devices on e-bay whenever I have spare time... idle paws, you know... anyhow, this time I found myself a Philips PM5705 pulse generator. Its sole purpose is to create a rectangular output signal with a given pulse width and repeat rate. This model can go as high as 10MHz and as low as 0.1Hz for the repe...
HP-3476B Cleanup
Переглядів 2,6 тис.4 місяці тому
Now, what do we have here? The 3476B is a portable DMM from the mid 1970s, so about the same age as myself! It does volts, amps and ohms; the former two in AC and DC. So nothing too spectacular by today's standard. But: digital! With a nifty display! Not Nixies, but the next best thing! The device was offered as complete; but just how complete it was took me by surprise. It arrived with the car...
HP1607A - Logic Analyzer
Переглядів 3 тис.5 місяців тому
Workshop Project #31 - HP1607A Logic Analyzer This time on the bench: a very early logic analyzer. The HP 1600A model that I restored about a year ago (link below!) has a companion model: the 1607A. During the 1600's restoration, I learned that these can be combined to form a 32bit wide unit, so I just got to have one. Normally, I'd be happy with the 1600, since it doesn't need any external dev...
Workbench Island: Drawer Update

Back in July 2022 - yikes! Almost two years ago! - I set up two workbenches for my mini lathe and mill. You can see the project here: ua-cam.com/video/rA_oc7iJncw/v-deo.html Since then, I have been using both of these machines quite often, but I didn't have time to complete the workbenches. This means that quite a few pieces of accessories are still where I left them when I set up the lathe... ...
