Voltlog #290 – Riden RD6006 Output Noise Using Recommended Power Supply NVVV S-400-60

Welcome to a new Voltlog, this will be a rather short video cause I will only be addressing one short subject regarding the Riden RD6006 ripple noise. In my review of this power supply in Voltlog #284 I did measure the output ripple but that was measured while using a transformer to power the unit. 

That transformer has very little output noise so the results we obtain can be considered best case scenarios but this may vary in practice, especially if you are using the recommended switch mode power supply. The output of that power supply may not be as clean as the one from the transformer so in this video I’m going to measure the output noise with the switch mode power supply installed.

I’m using the recommended NVVV 400W 60V 6.6A rated power supply, this is what RuiDeng officially recommends to use with their power supply kit. In Voltlog 284 part 3 I took a look inside this power supply so I will link that video on screen if you want to check it out.

Voltlog #289 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. Before I get started I’m gonna take a second to remind you to subscribe to the channel and hit the bell notification icon because that’s the only way you will know for sure when I upload new videos. 

I must say I’m noticing delays in delivery of these packages from China, it started with orders placed mid January and I’m probably going to see some packages lost and never delivered so i recommend you keep an eye on your orders and request a refund when the protection time expires.

Voltlog #288 – New BLTouch 3DTouch Plastic Pin Sensor Upgrade

Back in 2018 I installed a Bltouch sensor on my Creality CR10 3d printer and I showed the process in Voltlog #177, that video is one of the most popular videos on the channel and now after using the printer with the upgrade for a couple of years I can clearly say it’s probably one of the best upgrades you can do to your 3d printer and it’s pretty cheap. I won’t go into too much detail about what the sensor does and how to install it because that is discussed in Voltlog #177.

However I did experience a downside after this upgrade, some users are reporting the same problem while others don’t face this issue. It’s important to note I am using a BLtouch clone called 3D touch, purchased from Aliexpress. It’s the type that has a metal push rod through the middle. The issue I’m having is a vibration noise coming from that metal pin vibrating inside the sensor when the printer moves on the Y axis. This issue might or might not be present on a genuine sensor or just another unit which might have tighter tolerances.

Voltlog #287 – Switching From Eagle To Kicad

Welcome to a new Voltlog, today I’m gonna talk a bit about my process of switching from EagleCad to Kicad. So i’ve been an EagleCAD user for years, I’ve practically learned how to do pcb layout in eagle cad so there is that emotional attachment to a piece of software because it’s what I used while developing this skill. And to be honest there wasn’t any better alternative years ago, Eagle was the first decent piece of cad software to offer a freeware license and it quickly became popular for hobbyists. It didn’t have all the bells and whistles of the expensive software like Altium or Candece but it did the job while being user friendly.

Since it quickly became popular for makers and hobbyists it also meant there was an abundance of support on the forums as well as many user generated scripts and libraries freely available. It was similar to the popularity Arduino got but it was never open source and if you needed some extra features like 4 layer layout or pcb sizes larger than 8x10cm you needed to pay for a license.

Voltlog #286 – How Is The Coronavirus Affecting PCB Production?

Welcome to a new Voltlog, I have a couple of projects in the pipeline right now that require PCBs and as usual I will be getting them from JLCPCB who have been sponsoring my videos for a while now and even if they weren’t I would still be ordering from them because I like how their service runs. But the problem right now as you may know is the Coronavirus infection. In order to contain the spread of the virus, companies in China have moved to a work from home scenario with only minimal required personnel present  on site. 

This coupled with the extended holiday which was issued after the spring festival means decreased manufacturing capacity which leads to long lead times as customers line up to get their PCBs manufactured.

So this video is more an update on the current situation because I am in contact with JLCPCB and I want to give you some info on the expected delays for pcb orders. Right now they offer production of 2 layer pcbs as well as smt assembly service and stencil production service but 4 layer, 6 layer and ENIG coated pcb manufacturing has been suspended until further notice.

Voltlog #285 – Is a Cheap Cordless Power Drill Any Good?

Is a cheap cordless power drill any good? That is a question I’ve been asking myself for a while now because I was in the market for a cordless power drill. I can get a well known brand like Makita which sells a kit with two 18V 3Ah batteries, the drill and a charger for about $200. The thing is I’m using a tool like this maybe once every 3-4 months for a couple of drills, generally soft materials or maybe to assemble some new piece of furniture and I don’t feel like spending $200 for a tool that’s not going to be used and worked for that money.

So I started looking at alternatives, there are the clones of Makitas and Dewalts available for probably less than half the price of the genuine stuff but why go that route? I don’t care about what’s written on the label and the color of the drill.  One thing I care about is the shipping of the item, preferably I would like something that can be ordered and shipped from the EU for fast delivery and no additional taxes being paid for customs.

So I started looking at Chinese brands, this particular model got my attention on banggood.com, they call this a 36V cordless drill, it comes with two batteries and it’s available from a warehouse in the EU.

Voltlog #284 – Riden RD6006 Power Supply Review

Welcome to a new Voltlog, if you’ve been watching the channel for a while you might know I’m a fan of the gopher power supply units, I think they are great value for money, they’re simple and they have good specs, in fact I reviewed their latest revision in Voltlog #255 and it had very low noise at the output, even though it is a switch mode power supply. They’re pretty compact, they don’t take up much space on the bench so what’s there not to like about these?

But in recent years there’s been another company which has slowly built-up a name among hobbyists due to their really low priced power supply modules, the name of the company is RuiDeng and they’ve been selling these compact switch mode power supply modules for $20 to $30 for years. They were not great specs, the quality was not great, you needed an external power supply unit but they had a bunch of functionality built into that color TFT display and they were cheap so everyone gave them a try

Now RuiDeng has developed and released a new model RD6006 which resembles a real bench power supply. It has a bigger front panel and it comes with a separate enclosure and power supply unit which are optional.

Can The Coronavirus Travel With Packages Delivered From China?

Welcome to a new Voltlog and yes we are talking about the Coronavirus on this channel and you might think it’s completely unrelated but there is a connection as I will explain in a moment. You know I host a popular type of videos on my channel, that is the mailbag videos with electronic items that I get from China. I am ordering this stuff from Aliexpress, Ebay, Bangood but it doesn’t really matter which website we’re talking about, even on Amazon there are a bunch of shops that ship directly from China to the US or UK or whatever. 

Some of you might be asking is there a safety risk with the Coronavirus infection happening in China, is there a chance of that virus traveling with these products and infecting us the recipients of the packages? Well let’s look at the facts first.

Voltlog #283 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. Before I get started I’m gonna take a second to remind you to subscribe to the channel and hit the bell notification icon because that’s the only way you will know for sure when I upload new videos. I’m gonna start with an item that’s actually disappointing, this is a mini portable vacuum cleaner but I only realized this after receiving the item, because the seller of this item was advertising this as a dust blower vacuum cleaner, it’s the usual keyword stuffing that aliexpress sellers do.

Voltlog #282 – Did I get a trinocular microscope for micro-soldering and inspection?

Welcome to a new Voltlog, to save you from waiting, the short answer is yes, I did get a microscope for the lab but before I show you the microscope let’s talk about why I got a microscope and why you might want one. If you are occasionally soldering boards, electronic kits, mostly through hole components or even surface mount down to 0603 and you have good eyesight, then chances are, you don’t need such a microscope, I’ve been doing that for years.

On the other hand, if you want to be able to solder surface mount components smaller than 0603 comfortably or you want to do board level repairs on modern gadgets like smartphones and laptops, then you most definitely need a microscope as it will massively improve the quality of your soldering and the general repair process at your bench.
