More on syringe storage: If the paste prevents the tape from sealing, don’t squeeze any paste into the fold. BTW A 1mm syringe by itself (without the dispenser tool attachment) works well also. A microscope makes the ‘non-stencil’ solder paste process soooo much easier. [A.jpg] [B.jpg] [C.jpg] [D.jpg] [E.jpg]

I don't think this tips will explode and go wiral, but with this part in a Norwegian store cold "Biltema" i found this thing. Finally i have som order in my Jumper Wires :slight_smile: [image]

You can make durable jumper cables for your solderless breadboard by using heat shrink instead of a Dupont housing. The heat shrink acts as a strain relief. Clear heat shrink lets you see the condition of the M/F connector. [A.jpg] [B.jpg] [C.jpg]

larryd: You can make durable jumper cables for your solderless breadboard by using heat shrink instead of a Dupont housing. And they fit into a cramped breadboard better than the bulky DuPont connectors. My favorite manufactured jumpers are just like that.

Hot air does not always work for removing high mass SMD I.C.s. In these situations, cutting the leads is an effective way of removing a faulty chip. I find the 'Olfa AK-4' handle with an 'Olfa 9166 KB4-F/5 Chisel Blade' works best to cut the leads. All you need to do is push down with the blade on the lead, it cuts very easily.

Lately, I have been using a 1 ml Borosilicate glass syringe for depositing solder paste to PCB pads. I fill these to the .4 ml point. The smaller shape makes it easier to control where the paste goes, and it seems to give better flow control. The syringe’s shorter length and screwable plunger make for easy storage. The plunger's 4 rubber seals are much better than the 2 on plastic syringes. These glass syringes will be my go to for hand solder paste application. My thumb joint hurts less too. ;) These syringes can be found on Amazon and Ebay for about $15 for ten. [A.jpg] [B.jpg] [C.jpg] [D.jpg] Edit [image]

I often remove the rubber bulb from an eye dropper and attach a syringe in its place. The nice thing about using a syringe is you can 'accurately' draw up the needed amount of fluid for the job. The same syringe can be attached to a serological pipette and used in a similar manner. When gluing plastics it can be frustrating drawing DCM (methylene chloride) into the dropper. Adding a valve port hole in the syringe makes this job easier. See the images below for the modification: Melt a hole in the barrel end of the plastic syringe; this acts as a control valve. Placing a finger over the hole and pulling the plunger draws fluid. Removing your finger releases the vacuum and releases the fluid. A piece of Scotch tape returns the syringe to normal operation. Insert a glass bead in the syringe barrel to prevent the rubber piston’s seal from being damaged by the air hole. [A.jpg] [B.jpg] [C.jpg] [D.jpg]

Cover box for arduino (IoT) with EU plug Hi, I would like to ask you if you know about any socket (EU 220V) and box where can fit there voltage changer 220/3.3-5V include arduino (nano or smaller). Generally I am looking for case which have connector to wall socket and inside that box I can put my arduino stuff. Something like this: but without front socket (or even without usb plug). It can already contains step-down or trafo from 220V to 3.3/5V (it will make life even more easier :smiley: ) [image] or [image] Do you have any recommendation (even ebay, amazon ci aliexpress) Thank you.
