OP3N DOTT Bluetooth headset OP-987

OP3n DOTT ?! WTF ... newest company "from china with love".
Promoting nice 8" Intel CPU based tablet and smartphone, both with android. And here is some accessories for their smartphone and tablet,bluetooth headset
BT 4.0
Integrated MIC
NFC
sounds good!Get one and take a part.
What's under the hood?The Op3n dott don't want to reinvent the wheel.

As you can see he used the well known CSR-8635 module. Limited Datasheet and tools for flashing available on the net,not bad!
And what about the sound quality?Not too bad but if you want to get some nice quality tones probably you will be disappointed. Keep in mind this is a 35$ BT headset :D
Luckily I have a lot of headphones and headset parts. For example a  pair of sennheiser HD-180 headset speakers,and this is much better that the original ones.
The stock speaker

The stock speaker

Truly integrated speaker by Sennheiser.This was fluid XD?



upgraded speaker

Now the sound quality is much better of course.
I discovered something on the main board. Maybe an USB interface. I will try soon what I get if I connect this board to the computer.

    Hey I have these head phones. i have had the bending part break twice. but the real mystery is that after a year the battery just stopped. It will turn on if the USB is plugged in but nothing unplugged. when i plug in the USB the red LED comes on for 3 s and then off and nothing. Any ideas?

      Hi,
      Can you check your battery voltage? (DMM or something?)
      I will make a try, I will remove my battery and I check what will be happening.
      Stay tuned I write soon.

JBC AD2950 Display Backlight Mod

I really like my JBC soldering station, perfect and robous tool. I usually just put the handpiece back to its holder, and after a few minute the station will activate the hibernation mode (no heating). This is a great feature because you don't have to turn on and off the station, but sometimes, for example when your 2 years old daughter start exploring your lab this can be dangerous. If you let the iron in hibernation mode, it is start heating very quickly (5 sec. from room temp.) as soon as you pull the handpiece out of its holder. Fortunately, my daughter dropped down the handpiece in time, and she don't get burned, but this was a terrible mistake as a dad because things could be happen much worse than in my case. The problem is when the soldering station is turned on, you don't get enough visual notification about it. The display are saying "hibernation" of course, but if you tired or you are in hurry, you probably miss it, and you will forget to turn it off.

PCB Plotter a.k.a. Direct Ink To PCB

The simples method to manufacturing PCBs at home is the toner trasfer method.But the laser printer is the most important a part of this technic and the laser printer is expensive stuff for only printing some PCB / month. The cheapest method to manufacturing PCBs at home is using alcoholic pen and drawing the traces with your own hands . But our hands resolution or the precision is not enough in most case. The PCB plotter machine with CNC controlling are the solution of this problem. I spend my last weeks to build this PCB plotter machine from 2 CDROM driver and a floppy driver. The parameters: 38mm*38mm Workspace (enough in most case) 0.0735 mm / steep (in halfsteeping mode) Parts that is used: As I said  : 2 CDROM and 1 Floppy driver 3 * L293 Dual Full Bridge Motor Driver IC Power supply of course ATMEGA88 and USB2Serial bridge Some wires and pin headers The full cost is about 15$!!

Razer GreenSwich issue in BlackWidow keyboard

Recently, I got a used Razer BLACKWIDOW Ultimate 2014 mechanical keyboard with the fancy Razer greenswitches inside. The keyboard looks awesome and I really like the illuminated keys too. I'm not a person who likes the lound, clicking sounds that this switches are make when you press them down but I decided to give it a try. Sadly, the smile in my face went away as soon as I plugged the keyboard in and started typing on it. Every second or third character was doubled or missed on the screen of my computer. Something was wrong for sure with the keys, this issue is called scattering by the way. Actually I know that before I bought the keyboard and this is why I was bought it. There was nothing left, time to investigate the source of this issue. After a few phillips head screws I got inside the keyboard, and I desoldered some of the failed switches. The switch itself was easily disassemblable, 2 securing on each side. The problem was obvious after I looked inside the switch, corrod
