YIHUA 850AD Digital Display Hot Air Desoldering Station Air Pump Can Adjust Temperature Heat Gun SMD Phone Soldering Station (WHL #85)

I got a (reasonably) big box from China!

Since changing jobs, I’m in the process of buying tools that I dearly miss – some of them are no longer easily accessible in the new place, some aren’t available at all, and some are so darn useful, I should have bought a unit for myself at home ages ago. A hot air station checks the last two boxes, since my regular 2000W hot air gun is certainly useful for like removing stickers or preheating boards, but temperature regulation clearly isn’t good enough for soldering. So…I bought a Yihua 850AD. […]

AVM FRITZ!Box 7362 SL to 7520 upgrade + 7530 unlocking (#P39)

Quick reminder/PSA: Router patch week in every parent’s basement starts in a dozen days. Be prepared!

Not actually sure what type of…internet-free telephone service box thing my mom is using in the inherited farm house, but at my place, I needed an upgrade. Until earlier this week, an AVM Fritz Box 7362 SL (the cheapo 1&1 branded one) provided service. Bought that sucker 8 years and a month ago and it’s running just fine – except for the fact that it is considered EoL by AVM. That however is debatable, since on the one hand AVM announced EoM (end of maintenance) and EoS (service) dates for that box type to be June and December of 2019 respectively, but on the other hand nowadays no longer states exact dates for any product and has released FritzOS 7.13 for it just last month.

CR2025/CR2032 battery dummy for power consumption tests and a hungry Supermicro board (#P21)

This bugged me for quite some time now: Ever since a very nice dumpster revealed a stripped Supermicro server chassis including a Supermicro X8DTL board (Dual-1366) to me, the BIOS battery of that system seemed to be empty all the time. You see, I use this machine as an offline backup, so once every couple of months I fire it up, transfer my data, and unplug it from power and ethernet. And almost always it doesn’t start right up because the CMOS data is gone. Ideally it should be a headless unit, so that’s highly inconvenient.

I finally got around to test this – the fix will be another project for some day in the future. […]

Bosch Professional GAA 18V-24 USB charging adapter 1600A00J61 1600A00J5W (WHL #49)

Something out of the ordinary for today, a brand new item, bought for disassembly and kind-of off-label use. A Bosch Professional USB charger which happens to have a 12V port also…

Contrary to my very first thought when I found this charger, it does NOT allow 18V batteries to be charged from USB or a 12V source. Maybe I should test that, but I doubt it. However, it does convert the other way – stick in a 18V power tool battery (ranging from 1.5Ah to 12Ah as of today) and get a USB charger with a lot of oomph, or a “heated jacked” power source with a lot of potential for baggy pockets.

Samsung USB 3.1 Flash Drive BAR Plus MUF-256BE3/EU (WHL #45)

Wan Hung Lo #45 – Christmas Turd Edition!

Yeah…wasn’t planned to do that, but just like with the much more expensive “proper hardware” item from last year, the BenQ EX3501R that caused m u l t i p le revisits, I guess I found something worthy of in-depth reviewing. A simple USB flash drive.

Let me explain. I’m in the market for some 200GB+ device, as I’ve come to the point in the upgrade cycle where my 128GB Sandisk Extreme Pro (wank, wank) is no longer capable of holding all data that I want to carry around. […]

Waveshare 400×300 4.2″ three-color SPI E-Ink / E-Paper display module (WHL #38)

Bit of an upmarket item for today, not the usual Wan Hung Lo…had the honour to make that thing display some demo content for a side project at work. So…why not take some photos, publish the code, and get ahold of a similar unit for use at home?

So this is an e-Paper / e-Ink display, actually a module that consists of the display unit itself and a base PCB that takes the flimsy flat-flex connector, adds some passives and presents a more sturdy interface to the microcontroller that will be handling the thing. Also, the PCB is large enough to offer mount points on each corner. […]

Beetle Virtual Keyboard BadUSB Pro Micro ATMEGA32U4 Module Mini Development Expansion Board For Arduino Leonardo R3 DC 5V I2C (WHL #37)

Having no internet connection because your telephone provider screws up is bad enough – but this time, I screwed up. D’oh…
Well, I’m back, and now speeds have doubled. And cost has halved. Was that worth two weeks of heavily limited 2G/4G cellphone tethering interwebs? I don’t know, I don’t want to do that again… :???:

Today’s item is a small Arduino compatible board. I bought this mid-February for 3.52€ including shipping on AliExpress, and it arrived yesterday.

Why do I buy such a limited version instead of one of the larger (Pro Micro/Mini, etc.) […]

DC5V USB PORT 10X10CM El panel Electroluminescent BackLight panel el foil el paper el sheet Led Board Display with Inverter (WHL #35)

Here’s another random thing from a colleague: A small Electroluminescent panel!

I was asked for an area lighting thingy that is slightly flexible. So unless one wants to bend the stiff backing of a mobile phone backlight unit, EL foil seems to be the solution. I’m not sure if that fits his needs, but I’m confident he’ll tell me if it’s not ;) I bought this thing quite recently on AliExpress (mid-January 2018) for 5.22€ including shipping. Yes, shipping cost have increased by a bit, but shipping times have improved as well. […]

Weißen 128×64 0,96 zoll oled lcd led-display-modul für arduino 0,96″ IIC spi kommunizieren (WHL #6)

…Hi :cool:

I know, it’s been a while. Busy working, busy moving, busy buying metric shittons of furniture that’s not easily available in my size (or budget, or space, or all of them) and takes ages for delivery. Although this city is considered large for German terms, it’s not easy to get what you want – you might as well live in a backwater town. Well, actually I moved to such a lovely place and I couldn’t be more satisfied :)

About the promised “organic” next post: Here it is, I’m back. I’ll also throw in the other headline descriptions, as I actually bought another one for me (which I will review now), and two more for a work colleague who already snitched my first unit. […]
