:Aren't these devices basically Arduinos? It's written on the title atmega328. If so if we could get our hands on the code, we could make our own
I finally found the place where the Chinese get their code and design for the "Transistortester". It comes from a german site
a very extensive project. I doubt if I will ever be able to match or even comprehend what they accomplished. 
-
@AWI great digging!
The specs and list of functions are impressive.
Do you think the Chinese hardware is an identical copy of this design?

Why not? Chinese are great at copying stuff

:Why not? Chinese are great at copying stuff
Yes, and they're great in optimizing for cost; as long as any signal comes out, all components will be removed/replaced by cheaper ones...
-
@Yveaux I soldered the thing myself so build quality is ....
The board I received looks to be solid as well as the components.
Accuracy in resistor/ capacitor meaurement is fine (~5% which is also the toleration of the components tested) Semiconductor analysis is enough for me with Fet / Junction transistors as I can determine the most important characteristics (including the pin layout!) which are within 10% of the datasheet. (pins are 100% correct :-))
-
@AWI did you order the parts or did you make the tester on your own with the parts you had?
-
@gohan I used a kit. There is also a description and suggestions on improvement of the "Chinese clones" in the documentation of the project.
-
@AWI "I soldered the thing myself so build quality is ...."
I guess the missing word is: "top", and the last dot is just interpunction.
-
@core_c Thanks, I missed that
-
I got my 2017 transistor tester and since the cost for the pre-assembled was not far off from the kit, I did go the lazy way and I have to say the soldering quality seems OK.
-
I need little advice: is it worth buying the Ts100 soldering iron for 50€ + some accessories (holder and one extra tip, I already have a laptop power supply I can use) or go for a Hakko FX-888D for 120€ (you get holder in the price and extra tips cost significantly lower but I don't know if I ever need many different sizes)?
-
@gohan Imho - TS100 is beautiful toy, nice gadget, but not really useful tool. TS100 iron has much less ergonomics in comparation with others soldering stations. I recommend buy it only as extra tool, not main tool
-
After changing my HA and network to new location I made some changes to my workshop. Still some work in progress.
-
-
@sundberg84 we have the same model of soldering iron, hot air gun, and multimeter. And we might end up having a similar power supply too, as I'll build one sooner or later.
But my stack of unused EasyPCBs is a bit smaller

And some big spider to kill...
That is Hugo. He has been around since I was a kid. Hard to kill since he is made of plastic but loves to scare new people.
-
@nca78 - haha, thats nice
I been thinking about changing my power supply though. Posting to much images isnt good for you On my swedish blog I had a guy explaining about relative ground. When I probe around with my oscilloscope and power the electronics with my PSU they are not the same ground and this can apparently create some magic smoke. So far so good and I have been to lazy to learn more about the theory (Im sure there are people here with great knowledge about this) but the advice was to change my PSU to a "real" one.
-
So many space, I jealous

So I had to replace a micro USB connector on a tablet the other day. So to get the old connector off, I used my heat gun which is similar to the one pictured below. It worked okay and I was able to get the connector off.
I have been wanting to get a hot air re-work station for a while now. I was looking at the picture of @sundberg84 's workshop and I saw that he had an 858D, so I searched that on ebay. I noticed that there are a variety of 858D stations out there ranging from $30 to $121 US. They all look very similar as far as front panel controls and functionality. My question is, is there a big difference between the lower and higher priced units? I guess, if I get one of the $30 units, is it going to fall apart sooner than one of the others?
-
@dbemowsk i bought mine used from England. It was in the cheaper price range. Works great so far and this is ok for me.
-
@sundberg84 Thanks, hard to tell from your picture, but does yours have the cord for the wand going directly into the base, or is it on a connector that plugs into the front? I noticed that most of the more expensive ones have a removable/replaceable wand, but everything else looks to be about the same. I will probably just order the $30 one and see how it goes.
-
@dbemowsk I bought from AliExpress in the cheapest price range too (but not so cheap with shipping) and it's been working very well until now.
I bought this model, it's not available any more but there are plenty of seller with the exact same brand and model (Youyue 858D+), with extra nozzles (I had 3 only, now it seems 6 is standard) and accessories (I had none):
https://www.aliexpress.com/item/Hot-Air-Gun-700W-UYUE-858D-ESD-Soldering-Station-LED-Digital-Heat-Gun-Desoldering-Station-Upgrade/32657929118.htmlI opened it after reception to check for the common safety problems that were reported with first versions of the 858D/D+ models and it was safely wired and earthed.
It's also show the right temperature when overheating (it was not the case in the first models) so you know when to wait to avoid burning your board (don't worry this is only happening at start-up when it's heating fast from ambient temperature).
-
@nca78 They have a youyue 858D and it is $92 and another for $63. The ones I am looking at are these for $30 with free shipping:
-
Found an old post at eeevblog, where they hacked the Youyue heat gun. It was using atmega328p, so I am considering that one (even though they might have changed hardware since then. You'll never know what the sneaky people are doing ;))
-
@tbowmo So what improvements/changes did they do with the hack?
-
@dbemowsk better PID tuning etc.

Still need to do some setup and sorting of things, but here are some pics of my newly remodeled workshop area.
I really need to get rid of that old Leader analog scope and get myself a DSO. It is a conversation piece though. I have it connected to my old heathkit square/sine wave audio function generator. Does anyone have a recommendation on a cheaper DSO that would be good for microcontroller work?
-
I moved my desk to a new spot in the house and reoriented the desk. Still a mess, but that is how my mind seems to work these days: lots of stuff in parallel ...
-
Multiple parallel projects is a common problem
-
@gertsanders so that's what kept you busy last 7 months!
-
@gohan Agreed. I have up to 5+ going at any given time. That way I have something to do when one project goes stale or gets put on hold for a while.
-
@yveaux indeed. It seems there is always some other thing to do first. Moving my desk was part of a greater reorganisation of desks and rooms. I set myself deadlines to be able to advance a little (next one is 16 May: lasercutting boxes at the FabLab), but still progress is slow.
The fact that my switch to version 2.2.0 on sensors and on ethernetgateway on Raspberry is not going well, also slows down progress. Step by step ...

Well, if you need any help or have suggestions how to make the transition more smooth, you know where to find us!
Good to have you back on the forum though
-
@yveaux I'm not sure the issues is with the MySensors part. The gateway listens, but presenting a new node crashes Domoticz. After reboot I do see the new sensor and can receive and show updates, but the "new node" part is what bugs me now (I made a new node with atmega1284p which I want to add to my network)
I am using the beta version of the gateway & Domoticz
-
@gertsanders said in Your workshop
:I am using the beta version of the gateway
Why are you using a beta version? I thought 2.2.0 was in stable release?
-
@dbemowsk like to push my luck I guess
It seems the latest Domoticz beta (9379 build date 28.04.18-09:18:07) has a problem with presentation of new sensors. So I will have to sweat it until they fix that.
I compiled the gateway on Raspberry also with the beta version (after trying the stable version first), as it was mentioned that this could fix communication errors. No luck so far.
Bu this discussion of my problem should be on another forum branch.
-
Use the 2.2 stable, your is not a radio communication issue.
-
@gohan
Indeed, it is a Domoticz beta issue
-
As I have updated my workshop, so I no longer sit at my family kitchen table, but instead have a man-cave, behind a sliding-door closet, next to the water-heater
-
@bjacobse something is wrong, it's way to organized
-
@tbowmo
Well I must admit, it's just put in place - which means I have not yet started to use it - It must be messy when in use
-
resurrecting this old thread
I got thrown out of my old mancave, and in to a small corner in the main building (the oldest son, aged 21, needed a place to stay, as his 19 year old sister didn't want to share room with him)
Anyways, I have moved from a 240x60cm desk to a 120x80 desk, and no storage space around me, other than a small office cabinet on wheels. Which means that I have to constrain myself, and find some alternative setups. As I have to work from home these days due to corona, I treated myself with a monitor mount for my 3 screens.
As a bonus, I can now use the space below the monitors for my tools (power supply and soldering iron,and probably the oscilloscope as well, when I get to it). I'm re-arranging stuff every other day, to figure out the best setup, and remove cable clutter (which isn't easy).
-
@tbowmo is that KDE?
-
@monte said in Your workshop
:@tbowmo is that KDE?
Nope, Ubuntu / gnome, but with a tool bar at the bottom of the screen.
-
@tbowmo nice! I was too lazy to open full-size image
-
@tbowmo
Looks really good, hope you will spend many good hours doing some fun stuff
-
@bjacobse thanks, hope so too.
Just looked back into the thread, I posted a picture of my old workshop back in 2016, still the same tools around, just a smaller desk to work on.

I thought I'd share a part of my 'workshhop'. Only part of it due the rest being in a bit of a mess at the moment, so here is the 'good' bit......
-
@skywatch if this is the good & organised bit I would die to see the rest
-
OMG...
-
@skywatch that is looking very good, but why would you measure the wind speed of your workshop?
-
@Yveaux - I don't think it is really worth dying over
@mtiutiu - I guess you are referring to the lack of beer on the bench. Don't worry I will be sorting that out very soon!
@dzjr I eat a lot of hot spicy food and you can never be too careful!
Actually the wind speed anemometer is something I 3D printed. The problem is that I need to calibrate it and since I don't have access to a wind tunnel I was thining of securing it to the car and driving at different speeds to note the readings.
Only 2 problems I have found with that so far. 1 - In the UK there are very few calm days. 2 - We have been in lockdown for nearly 2 months and I can't go out to test it.
So it just sits there mocking me for going to all the trouble of creating it in the first place!
-
I assumed that my desk was a kind of a mess... but now I realize it's just average!
-
@MatiasV No-no, you need much more stuff before it will be "average"
-
@bjacobse I agree - when I was putting mine together I could see the desk top. But now it is in constant use 'building' I never know what I will find underneath something!
