Hackaday Belgrade 2018 is this weekend 26th of May. Get ready for Retro Computing BASIC badge hacking.

2018-belgrade-badge-featured

This weekend 26th of May Hackaday will have their second conference in Belgrade.

You can see the program here.

The conference badge is cool retro computer running BASIC. There will be badge hacking workshop so we will get with us some PIC-KIT3s .

I will have talk about how we hacked Soldering robot with ugly programming interface with TERES-I laptop and FPGA / Sigrok and how we replaced the soldering robot brain with OLinuXino-MICRO, so now it’s ready to take CAD CNC files and use fiducials and do AOI inspection after soldering.

 

TUXCON FOSS and OSHW conference 2018 in Plovdiv is just 18 days away, so plan your visit properly ;)

TuxCon 2018 conference about Free Open Source Software and Open Source Hardware will be June 9 and 10th in Plovdiv.

This is community driven event done by volunteers with the support of local IT companies and it’s totally free to participate.

In Saturday 9th of June in the Technical University building there will be two rooms, for lectures and workshops.

Hacking Risc-V core, implemented on iCE40 FPGA and playing with it’s instruction set and making small “monitor” program which allow you to enter programs written on machine code and executed on iCE40HX8K-EVB + iCE40-IO will be demonstrated, so if you want to touch and make your first program on RISC-V “computer” with VGA monitor and keyboard you may find Rangel Ivanov lecture interesting.

Plamen Vaisolov is retro computer maniac and keep working on them, implementing modern floppy disk emulators and other peripherials. He will share his experience with all these who miss Karateka and Load Runner 🙂

Neven Boyanov will talk about his experience with LoRA network and how to start on low budged.

Dimitar Gamishev has two interesting talks, one is for the Open Source Hardware and Software GPS car navigation he made. In the  second he will speak about the home assistants like Google Home and Alexa, how to implement them with small Linux computer like OLinuXino and even with ESP32-Lyra and how to impress your girlfriend by switching on and off appliances and lights with your voice.

There will be KiCAD workshop where everyone (even with no knowledge) will learn how to install, configure and make small robot PCB with KiCAD. Then some general knowledges about PCB materials and how to prepare all files and send to PCB board house for manufacturing. How to select the components, footprints, good routing practices, DRC/ERC checks, Gerber generation and tips how to design your PCBs in way to be produced at lower cost. At the workshop will be our design engineers and you can talk to them directly about issues you encountered when worked with KiCAD or other CAD product.

 

In Sunday 10th of June we will have traditional Soldering workshop at Olimex training building, where we will assembly and program with Arduino small robot which can follow line or escape from labyrinth. This will be the same robot which PCB we will design in the KiCAD workshop in the previous day. We will go detailed through the program and study how modifications affect it.

The workshop with end with barbeque in Olimex backyard 🙂

 

We are looking forward to see you in Plovdiv soon!

I’m going to speak at Hackaday Belgrade 26 of May.

My proposal:  Hacking soldering robot with TERES-1 DIY Open Source Hardware Laptop was just accepted!

I will speak about how we hack Soldering Robot and make it intelligent with additional camera, which makes possible use of fiducials. Making programming easy and post soldering quality check with OpenCV.

More about this event you can read (when available) on Hackaday Belgrade conference page.

New soldering products in stock: Solder paste and soldering wire

SLD-SAC305C4

We have new product category: Soldering components which include solder paste and soldering wires.

SAC305 solder paste is with the industry standard Sn96.5Ag3Cu0.5 composition. It’s ROHS compliant and has melting temperature 217C. The paste is Class 4 with 20-38um solder particles and is good for printing down to 0.4mm pich components. The packing is 0.5KG, we recommend to use fast shipment when order this paste as it must be kept at low temperature of 5-10C to prevent solder flux separation. The paste is good for 6 months from the date of manufacture.

Some applications are ROHS exempt and still use SnPb solder paste. This paste is with Sn63Pb37 composition and melting temperature 183C. The paste is Class 4 with 25-38um solder particles and is good for printing down to 0.4mm pich components. The packing is 0.5KG, we recommend to use fast shipment when order this paste as it must be kept at low temperature of 5-10C to prevent solder flux separation. You should not use this paste in ROHS compliant products as it contains Lead. The paste is good for 6 months from the date of manufacture.

For manual soldering we offer no clean SAC0307 ROHS compliant soldering wire with 2.2% Flux core and 0.6mm, 0.8mm and 1.0mm diameter. This alloy has melting temperature between 213 and 228C. Soldering iron temperature should be set between 245 and 375C depend on the components size.

For non ROHS compliant manual soldering Sn60Pb40 solder wire with 0.7mm diameter and 2% core Flux is available. This alloy has melting temperature 190C. Soldering iron temperature should be set between 240 and 350C depend on the components size.

 

TuxCon 2017 Open Source Hardware and Software conference will be 3-4 of June in Plovdiv

Just 70 days ahead is the 4th TuxCon conference in Plovdiv dedicated to Open Source Hardware and Software. For more info watch on conference page at http://tuxcon.mobi/

The entrance is free for all visitors. TuxCon is a community event and it is organized by volunteers.

3rd of June is the day for lectures and lighting talks, if you have something interesting to share please send your request to info@tuxcon.mobi

On 4th of June we invite you to the traditional soldering hardware hackathon in Olimex training building.

Open Fest 2016 – Soldering of the Open Source Hardware GHOST

“A ghost is haunting Europe—the ghost of communism.” said Carl Marx in 1848

We can re-phrase “A Ghost is haunting OpenFest 2016 – the ghost of open source hardware” 😀

We created this Soldering Kit specially for Open Fest as third year in a row we do soldering workshops there:

oshw1

It’s a very simple board, specially made for novices with small PIC10F206 microcontroller which has only 512 words of Flash memory and 24 bytes of RAM, still enough to write C code like this.

In the good Olimex traditions being overwhelmed with work we totally forgot for the soldering workshop and started the project 3 weeks before OpenFest 🙂

The board was quickly routed with KiCAD and we sent to PCB manufacturer in China, who keep the promise to make the blank PCBs for 1 week and shipped on time but DHL late with the customs clearance and we got the board Friday morning! The workshop was Saturday and Sunday, right on time!

Then we had half Friday fun with Microchip’s MPLABX tools, which refused to re-program the PIC10F206 once it’s programmed.

After few hours we found that MPLABX version 3.35 can program and erase PIC10F206 just fine but MPLABX 3.45 don’t.

Still there was enough time till 20.00 o’clock and we managed to program 200 kits ready for soldering next day 🙂

The initial intention was to make LED breathe but after losing so much time with MPLABX we decided the first version to be simple 10 times blink!

Here you can see people assembling it on OpenFest:

openfest

Girls, Boys, Kids all were not afraid and took the soldering irons:

openfest2

openfest3

After OpenFest we continued to investigate why the newer MPLABX refused to program PIC10F206 more than once, the problem was trivial, to erase it the Vcc must be above 4.5V:

voltage-configuration

Still interesting why MPLABX 3.35 was erasing it even without this voltage settings 🙂

This is why working with embedded systems is such fun. You never know where you can step aside and you have to worry not just for the code but also for the hardware as source of mistakes.

Needless to say we had no any assembly instructions for the kit at OpenFest, but now proudly we put them on the web site of the kit.

 

SoftUni camp Soldering workshop – 17th of August in Hisarrya

workshop

This week, right after our vacation we have been invited to make soldering workshop in SoftUni camp – the summer camp of the Software University.

More than 30 enthusiastic youngsters most of who have never worked with hardware assembled their first electronic boards and then learned how to program them with Arduino IDE.

work

The boards they assembled were: OLIMEXINO-85-KIT, FOSDEM-85 and SIMON-85-KIT

It was amazing that all of the boards were working at the end 🙂

ready
