Who here hasn’t put off soldering up a project because pulling out and setting up all your soldering gear is a pain? A lot of hobbyists don’t have a dedicated workbench for such activities and their gear may even be packed away somewhere inconvenient. [laxap] has come up with a solution using a plastic toolbox as a base for his Mobile Soldering Workstation.
[laxap] started with a regular off the shelf toolbox that has a lid and three drawers on the bottom. Although the Weller soldering iron base fit nicely in the bottom drawer, it did necessitate ditching the middle drawer for clearance. The compartmentalized top drawer is unmodified and holds parts and supplies in an orderly fashion.
Lifting up the lid of the box reveals a removable tray, which as intended, is a great spot to store tools such as a multimeter and wire strippers. The area under the removable tray is reserved for a power strip and power cord storage. A hole drilled in the side of the toolbox allows quick access to the power strip’s plug, a quick pull out and plug in is all that is necessary to get this workstation powered up.
That front flip up panel was made specifically for this project. Not only does it help keep the drawers from sliding open during transport, it also holds a lamp to aid in seeing what you’re doing! A bent aluminum strip acts as a latch to keep the panel in position.
It’s a pretty simple idea but it certainly gets the job done and makes soldering a whole bunch more convenient. If you like mobile workbenches, you may want to check out this all-wooden shelf style or one that features integrated solderless breadboards.
Photonicinduction is back! The Brit famous for not setting his attic on fire has built a 20,000 Watt power supply. It connects directly to England’s national grid with huge connectors. Impeccable fabrication and triple servo controlled variacs, and apparently this will be used for making a lot of hydrogen and oxygen through electrolysis of water.
In case you missed it, there’s a group buy for Flir’s Lepton thermal imaging module. Here’s the breakout board.
Need to solder something away from an outlet, and all you have is a disposable lighter? There’s a fix for that.
A Raspberry Pi case designed to be compatible with Lego. Now we need a hat/shield for NXT connectors.
Need another channel in your RC remote? Here’s this. It uses the gyro gain channel on a receiver. If someone wants to figure out how this works, wee do have a rather cool project hosting site.

Here’s something impossibly cool: The Macintosh PowerBop. It’s a Powerbook 170 with the floppy drive replaced with the radio in a cordless phone. It was part of France’s BiBop network, and you could buy private base stations for use at home. It is technically possible to use the radio as a wireless link to a modem, but [Pierre] couldn’t get PPP or a sufficiently ancient browser working. Plus ten points for taking it to an Apple store, and another twenty for trying to connect to our retro edition.
Chicken Lips. [Fran] and our very own [Bil Herd] are hanging out a bunch and recalling [Bil]’s time at Commodore. For this little featurette, [Bil] brought out his very own Commodore LCD. There are three of those in the world. Also included: tales of vertical integration, flipping bits with photons, and 80s era ERC.
Battery powered soldering irons are nothing new, but what about a soldering iron that can recharge via USB? [Solarcycle] realized that it might be handy to be able to recharge a portable soldering iron using such a ubiquitous connector and power source, so he developed the Solderdoodle.
The core component of the Solderdoodle is a Weller BP645 Soldering Iron. The heating element is removed from the Weller and placed into a custom case. The case is designed to be 3d printed. The STL files for the case are available if you want to make your own.
The Solderdoodle does away with large, disposable batteries and replaces them with a lithium ion battery pack. The battery contains no built-in protection circuitry in order to save space. Instead, this circuit is added later. [Solarcycle] appears to be using a circuit of his own design. The schematic and Gerber’s are available on his website.
The Instructable walks through all of the steps to build one of these yourself if you are so inclined. If you don’t have the spare time, you can fund the project’s Kickstarter and pre-order a production model. It’s always great to see a new commercial product with an open design.
Pick and Place machines are one of the double-edged swords of electronics.They build your boards fast, but if you don’t have everything setup perfectly, they’ll quickly make a mess. A pick and place can’t grab a resistor from a pile and place it – so far only humans can pull that one off. They need parts organized and oriented in reels or trays.
[Parker Dillmann] had to load some parts, but didn’t have a tray for them, so he 3D printed his own. [Parker] works at a small assembly house in Texas. He’s working on a top secret design which includes FFC connectors. Unfortunately, the connectors shipped in pick and place unfriendly tubes rather than reels. If he couldn’t find a tray, [Parker] would have to hand place those connectors as a second operation, which would increase the time to build each board and leave more chances for mistakes.
Rather than place each part by hand, [Parker] got in touch with his friend [Chris Kraft] who is something of a 3D printing guru. [Chris] confirmed that a 3D printed tray would be possible, though the PLA he prints with was not static safe. That was fine for the connectors, but [Parker] was hoping to save some tray space by putting his PSOC4 chips in the printed tray as well.
[Parker] used SketchUp to design a tray that would fit his Madell DP2006-2 pick and place. He left .15mm clearance around the parts – just enough to cover any inaccuracies during printing, but not enough to throw off parts placement. He sent the STL file over to [Chris] who used Simplify3D to a create a Gcode file. [Chris] printed the tray at .2 mm layer height on his MakerGear M2 printer, and the results looked great. Would they be good enough for the pick and place machine?
[Parker] received the printed trays in the mail and loaded them with parts. The pick and place had no problem finding and placing the connectors, making this job a huge success. [Parker] even left room for the PSOC4 chips.He plans to paint the tray with anti-static paint before giving them at try.
We really like this story – it’s a perfect example of how 3D printers can speed up processes in manufacturing. Now that the basic design is done, creating new trays is a snap. Nice work [Parker] and [Chris]! Continue reading “3D Printed Trays for your Pick and Place Machine”
[Anton] recently acquired a broken Nintendo 3DS. When the power button was pressed, the device would start booting up only to shut back down after flashing a blue light and making a popping sound. It turns out this problem is pretty common with the 3DS.
[Anton] could have tossed this device into the landfill, but where’s the fun in that? Instead, he cracked the device open like any self-respecting hacker would. It didn’t take him long to discover two broken flex ribbon cables. [Anton] could have then searched for replacement cables, but his inner hacker told him he could repair this himself. He carefully scraped the insulation off of the broken traces and then soldered on some hair thin wires to bridge the gap.
All that was left to do was to glue the wires securely in place and feed them back through the hinges. This project is a great example of how a little determination and know-how can keep a useful device from the landfill. If you attempt this repair yourself, you may find this 3DS teardown to be a helpful reference. What devices have you been able to save from an untimely demise?
Homemade reflow ovens are a great inexpensive way to quickly solder multiple prototypes at once. [Andy] may just have built one of the best ones we’ve featured so far on Hackaday. For his project a £25 1300W 12litre halogen oven was chosen because of its low cost and fast heating time, the latter being required to follow typical reflow profile ramp-up stages.
To control the AC power [Andy] first bought a chinese Fotek Solid State Relay (SSR) on ebay, which was quickly replaced by an american one after reading concerning reports on the internet. He then made the same ‘mistake’ by buying the typical MAX6675 thermocouple-to-digital converter from the same website, as he spent much time understanding why the measurements were wrong when the IC was just defective. His final build is based around a 640×360 TFT LCD that he previously reverse engineered, the cortex-M0 STM32F051C8T7, a SPI flash, some power regulators and buttons. The firmware was written in C++ and we’ll let our readers visit [Andy]’s page to see how well his oven performs.
With the launch of hackaday.io, our project hosting site, we’ve seen quite a bit of interesting hacks flowing in. While we feature some of our favorite projects on the blog, we’ve decided it’s time to start a regular recap of what’s going on in the Hackaday Projects community. We call it The Hacklet, and the first issue is now available.
This installment starts off with information on our Sci-fi Contest and improvements to the Hackaday Projects site. We talk a bit about the various projects relating to the Mooltipass password manager being developed on Hackaday. The Mooltipass has its own project page, but there’s also separate projects for the low level firmware being developed. Next we look at a pair of NFC rings for unlocking Android devices, and finish off with advice on soldering tiny packages.
Check it out and let us know what you think. Our goal is to summarize some of the neat things going on in the community, and we’re always happy to get constructive feedback from the community itself. Or you can flame us… whichever you prefer.
