Hi all,

 

I am looking around at places I can purchase from overseas as the local prices in my country are insane! A DHT22 temp/humidity sensor can be bought from Electrodragon for USD4.20, which equates to about ZAR63.00. The best price I can get locally is around ZAR275.00 which equates to about USD18.00 !!! They have many. many items I would purchase given their great pricing in comparison to my country. And don't even get me started on RS and DigiKey pricing.

 

Does anyone have experience buying from Electrodragon? Any feedback would be appreciated thanks.

No experience with that supplier, but in general, it may take a month or longer to get your parts from china.

If prices are that out of whack, then I suggest you purchase many and resell the others in your local area, become an importer/reseller!

I've purchased from Electrodragon, and got good service from Chow once I convinced him that I wasn't just some noob.  I wrote a review of their LGT8F328p module.
http://nerdralph.blogspot.com/20...

 

I like them for their in-house modules like the CH551/2/4, though Chow isn't quite a board layout and design expert.  The CH552T modules don't fit in a breadboard well because the pin rows are spaced ~13.2mm apart.  When I suggested he fix this in the next board rev by changing it to exactly 12.7mm (0.5"), he replied, "Thank you very much for the suggestion, 12.7mm is the good number and good to know, because we normally just try to measure the breadboard all the time."

Chow just told me they finished developing a HDSC ARM M0+ module, and should be listing it soon.  I'll likely buy a couple to try out once they are available.

 

When it comes to standard Shenzhen market parts like the DHT22, I tend to buy from Aliexpress or Fasttech where I usually can find them a bit cheaper than Electrodragon.

Thank you all for your feedback. i will look at the other sites suggested too.

 

The idea of selling some components locally is a good one. I will have to see if I can make that happen. yes

Wayne,

 

I have purchased several times from here.

I used to order cheap stuff from China (EBay), but SAPO is really unreliable in delivering these "free shipping" packages.  I stopped doing this after the postal service went on strike and I lost a package.

 

For future reference there are local vendors that are somewhat cheaper than your quoted price:

Rabtron (https://www.rabtron.co.za/arduin...) R114.54

Micro Robotics (https://www.robotics.org.za/DHT2...) R105.80

Add ~ R100 courier fee and it is again really expensive :(

I’ve ordered stuff from electrodragon a couple of times with no issues.

Suggestion: dht11/22 are old hat. Look at something like the bme680. More expensive but much much better.

Wasn't ElectroDragon one of the big players in bringing the ESP WiFi chips and modules to "the west"?
IIRC, they had useful wikis and forums while most people were still searching for english translations of the datasheets.

That gets them a couple "likes" from me.

Another Chinese vendor with way-above-average support and "understanding of the hobbyist market" is SeeedStudio  ( https://www.seeedstudio.com/ )

I suspect that stuff comes to the UK or US from China quite easily.

i.e. regular Freight on regular Freight aeroplanes.

 

In fact,  many Ebay "UK sellers" are actually Chinese that import regularly.   They claim to have UK stock in UK warehouse but probably receive bulk deliveries from China and post onwards to individual customers via UK mail.

 

The trick is to look at Ebay delivery times:

2 days implies genuine UK stock

7 days might be "just in time" from China

14-60 days means China via cheapest passenger/freight flight

 

UK does not charge tax or import duties on small packages.

I guess that the "just in time" packages will incur tax.

 

Hey-ho.   Ebay prices reflect the delivery times.

 

I suspect that South Africa will have less flights and always charge tax.   And your local postal service is slower than Royal Mail.

 

I sent a package to South Africa from the UK.   It took over a month to arrive.

Yet I sent package to Iran.   Arrived in less than a week.

 

I bet that any business can get freight deliveries in any country.   But freight cost might be high.   And Tax/Duty might be high.

As a business,  you can't avoid taxes but you might find cheaper freight.

 

I also bet that there are South African / Chinese businesses that already work effectively.

As a simple hobbyist,  I don't want to start a business.   Just buy small items with reasonable delivery times.

@valusoft (Ross)

 

Thank you for taking the time to point out the differences between the DHT11 and DHT22, I appreciate it. I was looking at the DHT22 because most of the so-called sensor boards seem use it instead of the DHT11, but the specs are very close so it would do the job perfectly for my application.

 

 

@ccrause (Christo)

 

I agree Christo, I know many people that have bought from sites like Wish.com and Banggood and never seen their parcels. i suspect it is the South African end where they go missing though given the state of our postal service. At least many of these places offer a free replacement if the parcel goes missing. I had a colleague who waited 4 months for a parcel then notified them it went missing. They replaced it and both the missing parcel and the replacement arrived at the same time! laugh If I buy from overseas I usually wait until I have enough I want/need or combine an order with others and use a track and trace service like DHL if the stuff is small enough. At least that way you know you have a very good chance of getting your items. Combining orders negates the high shipping costs through places like DHL.

 

I had forgotten about Rabtron and I didn't know of Robotics.org, I will check them out, thanks.

 

 

@Kartman and @westfw

 

Thanks for your feedback and suggestions.

 

 

@david.prentice

 

Thanks for your contributions. Here in South Africa we have a terrible postal service that 'loses' parcels at an alarming rate. A few years ago an investigation was done and people were literally found 'sorting' parcels based on what they sounded and felt like, and taking the ones that interested them home. Atrocious!

 

I also know that the postal service takes an inordinately long time to process mail and parcels from overseas, hence the long wait you had of a month. I think it has  something to do with the South African customs and excise. 30 years ago it would have been more like 3-4 months. Ask me how i know. laugh

 

The tax implications do also concern me, but there are many items that can be brought in with nominal/no tax implications. There are certain controlled items that incur higher taxation like GSM/GPS/GPPRS devices but they fall into specific categories for which I can source locally and pay less due to these taxes. Interestingly I saw that some places overseas are prepared to relabel items to prevent/reduce the tax implications. That is not clever in my opinion. if you get caught you will be in for a bit of trouble.

 

 

Again, thanks all for your feedback. yes

Here, air freight is an excellent business; a USA COVID-19 response is to shift some air freight to the airlines.

Interesting article David. I was wondering what the impact of Covid would be on international shipping. I remember seeing so many ships getting turned away from ports all over the world. It seems SA Container Depot in Durban, South Africa got lucky. They started their upgrades a while before Covid struck, and now they have the capacity to handle slow-moving container cargo. Other ports don't seem so lucky.

 

The airlines must be seeing this as another good revenue stream then!

I doubt if Air China small packets go by boat.   

 

I suspect that the "Free shipping" Ebay small packets go via a Chinese agent.   Who fills a single box (per destination country) which then goes by Air Freight.

The Chinese agent might wait until there are enough small packets to make the single box worth moving.

The actual air journey is probably quite swift.

UK customs might inspect the single box

The UK agent will unpack the single box and the individual packets go off to the UK destinations.

 

Pure speculation.   I have no special knowledge.    But I bet someone on this Forum knows how it works.

 

As a punter,   I would really like to know how long a small packet should take.
I don't want to pay $30 shipping for a $1 item.
I don't mind paying $5 shipping for a $5 item if it means 10 days.

"Free shipping" is obviously a lottery.

 

This obviously is different for Wayne in South Africa and for me in the UK

Well, JLCPCB advised me yesterday that my parcel was being shipped. Let's see how long it takes to get to Berlin. That's twenty small PCBs - about 80x50mm.

As someone who used to be involved with designing goods in the UK but having them manufactured in the PRC the fact is that to initially populate the market with some product we would air-freight a few thousand items but the majority would then come by shipping container which typically took 6 to 8 weeks on the water. So when things come from China and take 30+ days you can be pretty sure it's shipped on the sea not air freight. I can well imagine that Chinese "air freight" is used a lot for small packets of light components but if you buy 50 transformers or something it might well say "Air freight" but it's pretty certain to be on a boat and take 6+ weeks.

 

Aside: Aliexpress had their annual sale day on Nov 11. So I bought a Hantek DS02D10 oscilloscope. On Nov 21 I got an email to say it had been shipped. I was told it could take 50 days but if it had not arrived by then to seek recompense. Because of Brexit and Covid delays at our ports recent news reports have said that ships are being delayed and not able to dock so when it got to 50 days I gave it a bit longer. Any attempt to check the tracking number always simply showed "dispatched". In the end I lost patience and contacted the seller to try and get a clearer idea of exactly when it might arrive. Only then was I told "stock was returned by shipping agent" and "it's not coming". At least Aliexpress were good about this - I got the full refund 24 hours after I applied. Now when I go back to Aliexpress and order the same (this time with guaranteed 7-15 day DHL - so real air freight) I'm told it's a "pre-order" and the thing will not ship to the 20th. (also a lack of review videos on Youtube also made me wonder!). So it seems the item was delayed. I think they may have had design/manufacturing problems in fact. But I do feel a bit peeved that they couldn't simply tell me that or at least have sent me some update to say that it was not coming. At least this gave me the chance to (a) order direct from Hantek this time and (b) pay the few quid extra for the DSO2D15 which is 150MHz rather than 100MHz. We shall see exactly how long after the 20th it takes to "ship" across the world.

I am talking about the Ebay $1 transistor with Free Shipping.

 

Obviously heavy items are different.

 

Regarding an Oscilloscope.   Surely you would buy from the UK Distributor.

I bought my Rigol from Telonic in the UK.   Arrived at my door the next day.

 

Yes,  you pay more.

 

Yes,   I understand that sh*t happens.   In which case,   AliExpress, Hantek, Telonic, ... would should inform you.

But an oscilloscope is different to a $1 Ebay item that comes in a Jiffy bag.

 

Many AliExpress sellers have abandoned "Free Shipping" and quote "shipping costs" for small items.

They only promise 50 days but the items actually arrive at my Front Door within 7-10 days.

I would imagine that economy of scale plays a very big part of the logistics behind freighting items overseas. As said above, if you process enough orders on a daily basis, to hold off on shipping for a few days to fill a big box and send out say 20 orders for one country in that one box would save them a fortune, and as I suspect, a lot of companies would do this and turn the shipping charges levied into a bit of a profit-making exercise.

That is my guess.    How else can you get a jiffy bag arrive at your door from China containing a $1 Ebay item?

 

But you can also see how a UK "seller" can have regular deliveries from her Chinese Warehouse.

100 20g packets is only a 2kg box.   She can afford the DHL cost if she charges her local UK customers UK prices.

 

If she is good at her job she might keep popular items as UK stock.

I can also recommend their assembly service. Stupidly cheap and I got exactly what I expected. Pity they don't do through hole and the choice of components is sort of limited.

Haven't looked into that - do they use LCSC as component source? My board is designed to use only LCSC parts so I could get them all from the same place.

 

I'm still waiting for an LCSC order, ordered a couple of days later.

Sometimes I wonder how many "miles" an entire product BOM has travelled to build, say, an automatic water sprinkler & whether anyone is optimizing the assembly.  Say you are on the east coast and order a power supply from the west coast, that uses a fuseholder made on the east coast (so the fuseholder ends up traveling shipped back & forth).  Also the fuseholder terminals were stamped in a plant in Arizona---so those were shipped coast to coast more than once!  Sounds like a way to keep transporters busy shipping things back and forth, with room for a lot of efficiency optimization.  Bet that would make a good business opportunity!

     

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!
