Roll Your Own JBC Soldering Station

November 6, 2017 by Al Williams 23 Comments

[Marco Reps] was soldering some boards with a lot of thermal mass and found his usual soldering iron was not up to the task. He noticed some professional JBC soldering stations that he liked, but he didn’t like the price. Even an entry-level JBC station is about $500 and they go up from there. He decided to build his own, but it did take awhile to complete. You can see two videos about the project, below.

How can you build your own soldering station and still claim it is a JBC? [Marco] noticed that the real performance of the iron came from the tip — what JBC calls a cartridge. In addition, the handle provides good ergonomics. You can buy the tips and handles from JBC for considerably less than a complete station. You just have to add the electronics to make it all work.

Field Expedient Quenches Your Thirst For A Soldering Station

September 19, 2017 by Al Williams 21 Comments

In the category of first world problems, it seems that these days no one is happy with just a plain old soldering iron. Today, everyone wants a station with bells, whistles, and features. If all you have is the iron, take heart. Grab a soda, drink it, and then duplicate [Kalvin178’s] makeshift solder station.

The idea is simple: cut or tear a soda can and press in the sides to make a V-shaped holder for the iron. A smaller part of the can might hold a wet paper towel, a sponge, or some copper scrubbing pads to clean your tip.

Another Helping Hands Build

June 25, 2017 by Al Williams 4 Comments

[Punamenon2] wanted a soldering station with integrated helping hands. He couldn’t find one, but he decided it would be a good 3D printed project. In all fairness, this is really 3D printing integrating several off-the-shelf components including a magnifier, a soldering iron holder, a soldering iron cleaner, a couple of “octopus” tripods, and some alligator clips. Total cost? Less than $30.

In addition to holding the Frankenstein monster together, the 3D printed structure also provides a storage tray with special sloped edges to make removing small screws easier.

One Soldering Controller To Rule Them All

March 8, 2017 by Anool Mahidharia 22 Comments

If your favourite programming language is solder, they you’ve surely worked your way through a bunch of irons and controllers over your hacker existence. It’s also likely you couldn’t pick one single favourite and ended up with a bunch of them crowding your desk. It would be handy to have one controller to rule them all. That’s just what [sparkybg] set out to do by building his Really Universal Soldering Controller. His intent was to design a controller capable of driving any kind of low voltage soldering iron which used either an in-line or separate temperature sensor (either thermocouple or resistive PTC).

This project has really caught on. [sparkybg] announced his build about two years back and since then many others have started posting details of their own Unisolder 5.2 builds. [zed65] built the version seen to the right and [SZ64] assembled the boards shown at the top of this article.

The controller has been proven to work successfully with Iron handles from Hakko, Pace, JBC, Weller, Ersa, as well as several Chinese makes. Getting the controller to identify one of the supported 625 types of iron profiles consists of connecting two close tolerance resistors across the relevant pins on the 9-pin shell connector. This is a brilliant solution to help identify a large variety of different types of irons with simple hardware. In the unlikely situation where you have a really vague, unsupported model, then creating your own custom profile is quite straightforward. The design is highly discrete with an all analog front end and a PIC32 doing all the digital heavy lifting.

To get an idea of the complexity of his task, here is what [sparkybg] needs to do:

“I have around 200 microseconds to stop the power, wait for the TC voltage to come to its real value, connect the amplifier to this voltage, wait for the amplifier to set its output to what I want to read, take the measurement from the ADC, disconnect the amplifier from the TC, run the PID, and eventually turn the power back on. The millivolts to temperature calculation is done using polynomial with 10 members. It does this calculation using 32bit mantissa floating point numbers and completes it in around 20 microseconds. The whole wave shaping, temperature calculation, PID and so on is completed in around 50-60 microseconds. RMS current, voltage and power calculations are done in around 100 microseconds. All this is done between the half periods of the mains voltage, where the voltage is less than around 3 volts.”

The forum is already over 800 posts deep, but you can start by grabbing the all important schematic PDF’s, Gerbers, BoM and firmware files conveniently linked in the first post to build your own Unisolder5.2 controller. This Universal Controller is a follow up to his earlier project for a Hakko T12/T15 specific controller which gave him a lot of insight in to designing the universal version.

[sparkybg] has posted several videos showing the UniSolder5.2 controlling several types of Irons. In the video after the break, he demonstrates it controlling a Weller WSP80.

Portable Workbench Crams An Entire Workspace Into One Box

September 17, 2016 by James Hobson 7 Comments

Making on the go is sometimes required in today’s busy lives, and if you find yourself traveling — say, off to university like [ZSNRA] — then a convenient solution is required. To that end, a portable electronics workbench was built in the shape of a relatively nondescript plywood box.

Plywood and foam-core are the main materials used in building this maker’s bug-out box, with two fir runners along the bottom so the case is not resting on the hinges. Inside, [ZSNRA] has packed a staggering amount of hardware which results in an 11kg suitcase.

Here goes — deep breath now: wires, solder, resistors, transistors, capacitors, diodes, clips, switches, logic chips, non-logic chips, an Arduino, ATmegas, fuses, pliers, wire strippers and cutters, angle cutters, tweezers, a 66-piece screwdriver set, a desoldering pump, 12 needle files, a hacksaw blade, a multi meter, oscilloscope, power source, four outlets built into the case(!), steel wool, a third hand, a soldering station, two handbooks, and a breadboard.

Whew.

The work surface is an ESD mat on the inside of the case’s front face that is comfortable enough to work with, though we are surprised that it doesn’t also fold out somehow to create an even larger work-space.

For an elegant — if slightly less mobile — workbench solution, check out The Tempel. Now if you’re looking for ideas on how and what to carry we still think [Kenji Larsen] has the ultimate hacking kit.

Feel Extreme Workbench Envy After Seeing The Tempel

July 4, 2016 by Gerrit Coetzee 24 Comments

For those of us with space to spare, our workbenches tend to sprawl. The others who are more space limited will certainly feel envy at [Love Hultén]’s beautiful Tempel workbench.

The workbench appears at first to be a modern interpretation of a secretary’s desk. There are some subtle hints that it is no ordinary piece of furniture. The glowing model of our solar system on the front, for example.

With the front folded down, rather than the expected leather writing pad and letter sized drawers, a few more oddities become apparent. The back is a pegboard which holds a small selection of tools. To the left, a checkered grid obscures speakers. Knobs control volume There are even USB ports. On the right sits another speaker. Banana jacks let you use the analog voltmeter. Most appealingly, the indestructible Hakko 936 soldering iron has been entirely integrated into the structure of the desk.

If you press the right button on the front, the desk will reveal its last secret. It contains an entire workstation somewhere behind the array of drawers on the front. A linear actuator pushes a computer monitor up from inside the cabinet, covering the pegboard in the back. Awesome.

There is a build log, but unfortunately it’s been imageshacked and only the words remain. We think [Love Hultén] has finally managed to build a soldering station that’s welcome in every room of the house except for the garage.

DIY Hakko Soldering Station

January 5, 2016 by Al Williams 8 Comments

[Julez] wanted another soldering station, so he decided to build one himself using a Hakko 907 soldering iron (or a clone). Of course, he could have bought a station, but anyone who reads Hackaday doesn’t require an explanation for why you would build something you could buy.

The station has two switchable outputs so you can use two different irons (perhaps with different tips) although you can only use one at a time. [Julez] bought a case with a transparent top from eBay and also got a digital temperature controller from eBay, which is the heart of the project. As for the actual iron, you can find clone versions of the 907 handpiece for well under $10.

Because the station uses a module, the actual wiring isn’t terribly difficult. There’s a pot to control the temperature and the controller directly connects to the iron’s heating element and temperature probe. There’s also a standby switch that reduces the temperature using a fixed resistor in series with the control pot.
